DEDICATION
It is with great pleasure that we dedicate this
volume to Dr. Milton W. Sanderson, the dean of
North American Phyllophaga specialists for over
50 years. He was the moving force which
enabled this study to be completed, and he has
always been willing to share his phenomenal
knowledge with younger workers. His monu-
mental collection, accumulated during his tenure
at the Illinois Natural History Survey, will be the
mecca to which all future specialists must go.
His personal friendship to the senior author
resulted in the donation of his library, manu-
scripts, many new species, and other pertinent
materials. Without his stimulation and continued
support, this volume would not have been
completed.

FOREWORD
This is the Part II of The Scarab Beetles of
Florida, initiated in 1973 by Dr. Robert E. Woodruff
with Volume 8 of Arthropods of Florida and
Neighboring Land Areas, (Coleoptera: Scarabaeidae)
Part I. The Laparostici (Subfamilies: Scarabaeinae,
Aphodiinae, Hybosorinae, Ochodaeinae, Geotrupinae,
Acanthocerinae). The high standards of accuracy and
attention to detail are continued in this volume. The
difficult task of preparing a treatment of the subject that
is understandable to the novice and at the same time a
scholarly and comprehensive presentation for other
systematics authorities is accomplished.
This volume is based on more than 30 years of
extensive collecting in many parts of Florida in all
seasons of the year by the senior author, using a variety
of collecting techniques. As in the first volume, virtu-
ally all known collection records for the group studied
are given, and questionable and potential Florida rec-
ords are considered. Over 100,000 specimens were
examined.
In their treatment of the large and difficult to
understand genus Phyllophaga, the authors have made
extensive use of genitalia as the most reliable means of
species identification. Genitalia of all known Florida
species and those of some closely related species are
exceptionally well illustrated through the use of scan-
ning electron microscope photographs of the highest
quality. An extensive bibliography documents infor-
mation presented in this volume and presents refer-
ences for anyone who wants to study the subject further,
although the present volume gives a comprehensive
treatment of whatis known about Florida Phyllophaga.
The present faunal study, like that treated in Part I,
is provided primarily as a manual to assist in the iden-
tification of the Florida species. Specific identification
of an organism is essential to understanding the role it
plays in the environment and in determining the course
of action for controlling those species that become a
problem to humans. The name is the "key" to the
published literature and is essential before controls are
attempted. Illustrated keys for the identification of the
Florida species are provided along with an adequate
description of each species.
Dr. Robert Eugene Woodruff or "Bob" as he is
called by his friends and associates, was born in Ken-
nard, Ohio, on 20 July 1933, son of Marvin C. and
Thelma B. Woodruff. On 27 June 1954 he and Nina
Evelyn Gunsaulies were married in Urbana, Ohio,
where Bob's parents still reside. They have 2 children,
Kris Eugene Woodruff, 29, now living in San Juan,
Puerto Rico, and Cheri Ellen Taylor, 33, now residing
in Silver Spring Shores, Florida. Bob and Evelyn have
2 grandchildren. Bob was educated in the public
schools of Ohio. From early childhood he expressed an
interest in the natural sciences. In 1950 and 1951 he
entered the Junior Science Fairs of the Ohio Academy
of Science, receiving superior awards both years and a
scholarship to any of the 10 state universities. Follow-
ing graduation from Urbana High School in 1951, he
enrolled at Wabash College in Crawfordsville, Indiana.
During 1951-1952 he served as Curator of the insect
collection at Wabash College. The following year he
transferred to Ohio State University where he received
the Bachelor of Science degree with a major in ento-
mology in 1956.
From 1952 to 1955 he was an assistant in the De-
partment of Natural History of the Ohio State Archaeo-
logical and Historical Society Museum where he gained
valuable experience and training under Dr. Edward S.
Thomas and Mr. Robert Goslin. From 1955 to 1957 he
held a graduate assistantship in the Department of
Zoology and Entomology at Ohio State University,
under Professor Josef N. Knull, Curator of the Entomo-
logical Museum. This experience led him to specialize
on the beetle family, Scarabaeidae. Prof. Knull intro-
duced him to the "scratch board" technique of beetle
drawings which he has used in most of his publications,
including 32 habitus drawings in Part I of The Scarab
Beetles of Florida, published in 1973.
From 1957 to 1958 he was employed as a medical
entomologist with the Kentucky State Health Depart-
ment, in Louisville, working on St. Louis Encephalitis
and related mosquito projects. He attended special
courses of instruction on insects of medical importance
at the U. S. Public Health Service, Communicable
Disease Center, in Atlanta, and at the Tennessee Valley
Authority, Wilson Dam, Alabama. In March 1958 he
joined the staff of entomologists at the State Plant
Board of Florida (now Division of Plant Industry,
Florida DepartmentofAgriculture and Consumer Serv-
ices). He was initially employed as the "Survey
Entomologist" to coordinate the federal-state Coop-
erative Economic Insect Survey, in Florida, which he
fulfilled until 1963. The responsibilities included field
surveys, identifications, and reports for pests of turf,
field crops, vegetables, fruit, pastures, and ornamental
plants.
From 1963 more emphasis was on detection of
foreign pests and primary identification for beetles
(Coleoptera) and grasshoppers (Orthoptera). Biologi-
cal control and pest management have been investi-
gated with pests introduced from Latin America. Re-
sponsibilities included curating the Coleoptera and
Orthoptera for the Florida State Collection of Arthro-
pods, now the fifth largest arthropod collection in the
United States, and the development of the entomologi-
cal portion of the DPI library. Consultancies were
interspersed with this position from 1978. Retirement
after 30 years of service for the State of Florida was
effective 31 July 1988. He continues to serve the
program as an Emeritus Entomologist.
In September 1963 Bob entered the Graduate School
of the University of Florida, from which he received the
Doctor of Philosophy degree with a major in entomol-
ogy in 1967. As a part of his studies he attended a
session of the Organization for Tropical Studies at the
University of Costa Rica. His research has taken him to
much of the U. S. and the following countries where he
has collected and studied specimens: Antigua, Argen-
tina, Australia, Barbados, Bolivia, Brazil, Colombia,
Costa Rica, Cuba, Dominican Republic, El Salvador,
Fiji, Grenada, Guadeloupe, Guatemala, Haiti, Hondu-
ras, Jamaica, Mexico, Montserrat, Nevis Island, Nica-
ragua, Paraguary, Peru, Puerto Rico, St. Kitts, St.
Lucia, St. Vincent, Trinidad, Uruguay, and Venezuela.
He has received grants and contracts from the Ohio
Academy of Sciences, United States Public Health
Service, National Science Foundation, Smithsonian In-
stitution, U. S. Department of Agriculture, Australian
Academy of Sciences, Florida State Museum (since
July 1988 the Florida Museum of Natural History),
Illinois Natural History Survey. In 1988 he held a
consultancy with FAO (United Nations) in Barbados,
St. Lucia, and Grenada; and Agro Delta in the Domini-
can Republic. In 1989 he held a consultancy with Texas
A. & M. University in College Station, Texas and
Dallas, Texas. He is currently consulting with United
Nations, FAO and has a 6-month Fulbright Fellowship
for research in Paraguay.

Brenda Miller Beck was born in Key West, Florida
on 23 October 1948, daughter of George P. and Bonnie
S. Miller. Brenda and Dennis A. Beck were married 1
July 1970 in Gainesville, Florida. They have one
daughter, Jessica Denise, age 5. Brenda received her
elementary and high school education in the public
schools of Florida, Oklahoma, and Texas, graduating
from Gainesville High School in 1967. Brenda worked
at the University of Florida during the summer prior to
her last year of high school. In March 1974 she received
the Associate of Arts degree from Santa Fe Commu-
nity College, in Gainesville, Florida. She began work
with the Division of Plant Industry in 1968 and has
worked continuously in the Bureau of Entomology for
21 years. Currently a Laboratory Technologist IV,
Brenda has worked extensively with Coleoptera, par-
ticularly in the preparation of genitalia ofscarabaeid
beetles for study, involving scanning electron photo-
microscopy, and identification of Scarabaeidae and
tera. For many years, under the tutelage of Dr. Woodruff,
and also for the past year under Dr. Michael Thomas,
Brenda has served as the principal, active curator of
the Coleoptera and Orthoptera collections of the
Florida State Collection of Arthropods. Shealsohas
worked extensively in the curating of the large
alcohol-preserved, compactor-stored collections of
the FSCA, and the computerization of collection data.
In recent years she has worked also with Dr. Howard
Weems on the annual summary of all donations to the
FSCA, the computing of estimated values of these
donations, and preparation of several thousand
formal letters of acknowledgment which have been
sent to donors. Working with Dr. Woodruff, Brenda
has acquired a considerable knowledge of the identifi-
cation of Scarabaeidae and other Coleoptera. Her
current research interest is centered on the Phylloph-
aga of the United States and the West Indies. In
February 1989, at the request of Dr. Robert L.
Crocker of Texas A. & M. University, Brenda spent a
week at Texas A. & M. training personnel on the
extraction of Scarabaeidae genitalia and their prepara-
tion for study. Brenda was raised as a Baptist Her
hobbies are raising horses and dogs and working with
plants. She also enjoys writing poetry and some fiction.

PREFACE
When Part I of this series on the "Scarab Beetles
of Florida" was published (Woodruff, 1973), it was
anticipated that succeeding parts would be completed
soon thereafter. The press of routine duties, consider-
able travel and field work, and the volume of speci-
mens have each contributed to this 16-year delay.
The senior author's retirement in August, 1988,
provided the impetus and opportunity to complete the
manuscript. The delay allowed the inclusion of many
more specimens and permitted the illustration of the
genitalia and other taxonomic characters by use of the
scanning electron microscope. We believe it was
worth the wait, and the resulting publication should be
more useful for identifying the Florida fauna of these
interesting insects.
This part is co-authored, the work and responsi-
bilities being equally shared, except for the final
writing. The authors have jointly worked for over 50
years with the Florida Department of Agriculture,
during which varying amounts of time were spent
preparing specimens and data for this eventual publi-
cation. We have also prepared many of the specimens
and recorded much of the data for the final part (III),
which will include the remainder of the Melolonthinae
and the subfamilies Rutelinae, Dynastinae, and Ce-
toniinae. We anticipate completion of Part III without
the attendent delays previously encountered.
As with Part I, emphasis was placed on preparing
a faunal study to enable the user to identify specimens
and then to learn what is known about that species. It
is therefore a compilation of original data, integrated
with the existing literature on the Florida species.
Such faunal surveys are useful to a wide audience,
including homeowners, biologists, biogeographers,
ecologists, entomologists, pest control operators, and
environmentalists.
Permanent preservation of vouchered specimens
is an important part of any such study. The Florida
State Collection of Arthropods* is the primary reposi-
*The Florida State Collection of Arthropods is com-
posed of several collections which were previously main-
tained as separate: Univ. Florida, Agr. Exp. Sta.; Univ.
Florida, Dept. Entomology and Nematology; Florida State
Museum; Florida State Plant Board; and Division of Plant
Industry. My private collection (REW) of Scarabaeidae is
located with this collection which is abused by the Division
of Plant Industry, Florida Dept. Agr., Gainesville, Florida

tory for our specimens, and it is now the second best
collection of this genus in the World (behind the
Illinois Natural History Survey; see Woodruff, 1987).
Many times during this study we were stymied and
unable to solve problems, because previously reported
specimens were not documented and properly vouch-
ered in a permanent public collection.
Our emphasis on providing an identification manual
required that some traditional elements were short-
ened by time and space restrictions. Although the
species of Phyllophaga are externally similar, their
distinctive genitalia provide exceptional characters for
identification. As a result of this, long verbal descrip-
tions are both superfluous and misleading. We thus
chose to expend our time and energies in preparing the
genitalia illustrations from scanning electron micro-
scope photographs (Plates 1-32, fig. 1-378).
We believe that these illustrations should permit
easy comparison and positive identification, far better
than words could convey. Ironically, just 100 years
ago, Smith (1889b:485) first used these structures with
the following comments: "No words could accurately
describe their peculiar turning and twistings. I shall
not undertake verbal descriptions of these parts, but
prefer to let my figures answer most questions."
We hope that this volume will stimulate collectors
and students to pursue the many gaps in ourknowledge
of a dominant element of our diverse Florida insect
fauna. If it accomplishes these goals, we will be repaid
adequately for the efforts expended in its preparation.

FRACT
In this faunal study, data are presented for 54 species of Phyllophaga recorded from Florida. Two new
species, pseudofloridana and skelleyi, are described, and 9 other species are recorded from the State for the first
time: anxia LeConte, apicata Reinhard.forbesi Glasgowfoxii Davis, implicit Horn,perlonga Davis,profunda
Blanchard, puberula DuVal, and yemasseei Cartwright. In addition, illustrations are provided for the first time
of the female genitalia for 4 species: clemens Horn, elizoria Saylor, georgiana Horn, and okeechobea Robinson.
Two species [P. murrea Sanderson, previously known from a unique female, under P. elongata Linell, and P.
vanalleri Schaeffer, originally described as a subspecies of obsoleta, under obsoleta (Blanchard)] are syn-
onymized.
Scanning electron microscope photographs are provided for the male (4 or 5 views) and female (2 views)
genitalia, as well as other relevant taxonomic characters. Data are presented for each species under the following
headings: synonymy, type locality, diagnosis, description, taxonomic notes, distribution (Florida and United
States), biology and ecology, adult host plants, immatures, specimens examined, and selected references. Maps
showing both Florida and United States distribution are provided for each species.
Keys are provided for the adults of 54 species, and for the known larvae of 23 species. Eight tables provide:
1) an alphabetical checklist of figures and maps; 2) a chronological list of Florida Phyllophaga descriptions; 3)
the arrangement by "groups" of various authors; 4) a summary chart of life cycle data; 5) an alphabetical list and
references to known larvae of Florida species; 6) a list of 17 misspelled names of Florida species, and their
citations: 7) an annotated alphabetical checklist of the 96 names used for Florida species; and 8) a summary of
22 basic taxonomic character states. Specimen label data are listed in the Appendices (1-39) as is a list of the
figures (40), and the Bibliography contains 376 references.

over 50 similar species would rarely be helpful and
would occupy an inordinate amount of space. We
believe this is a special group in which the saying, "a
picture [of the genitalia] is worth a thousand words",
aptly applies. We have discussed the following char-
acters for each species: Length was measured from the
tip of clypeus to the tip of elytra (not abdomen, which
may move, especially after dissection). These num-
bers represent the minimum and maximum length in
our series of specimens to the tenth of a millimeter.
Width was measured at the maximum point (variable
because some specimens have elytra slightly separated
at the suture and therefore appear wider). These
numbers represent the minimum and maximum in our
series of specimens. Numbers in parentheses, fol-
lowed by an author's name, are extensions (either
direction) of our measurements and the reference for
them. Shape: Thegeneral form isdescribedasoblong,
oval, parallel, widest behind, convex, or subdepressed.
Color: The species of Phyllophaga vary from pale
yellow through various shades of brown to nearly
black. Unfortunately no standards have been estab-
lished for these colors, and they are difficult to express
precisely. The older, latinized terminology, used by
LeConte, Hor, et al., has been followed by most
workers. Even though we don't believe the terms
convey the shades of color effectively, we have no
better system at present. However, many species are
distinctively colored and often can be rough sorted
from mixed collections by color alone. Vestiture: The
surface coating is either pubescent (hairy), pruinose
(velvety), or glabrous (smooth). Occasionally a spe-
cies (e.g., aemula) has the surface pruinose and pubes-
cent. The hairs setaee) of pubescent species may be
recumbent or erect, short or long, dense or scattered,
and may differ on head, pronotum, elytra, and abdo-
men. Glabrous species are shiny or dull. Antenna:
The most obvious character is the number of segments
(from 9 to 10), and the sexual dimorphism in length of
the club (larger in males). The length of the male club
is given in relation to the previous segments of the
scape (stem). Clypeus: The front margin is either
entire (not indented at middle) to emarginate (with
median indentation deep, shallow, or moderate). The
margin is reflexed or not, the edge raised prominently,
moderately, or slightly. Tarsal claws: The claws are
curved slightly or strongly. They are cleft in the
subgenus Phytalus (georgiana & obsoleta), but toothed
in nearly all others. The tooth position is most fre-
quently median, but may be basal, nearer the base
(subbasal), or nearer the tip (antemedian). The tooth
shape may be acute, blunt, and prominent or reduced.
It appears to be absent in males of panorpa. Male
posterior tibial spurs: Normally there are 2 enlarged
terminal spurs, the lower (outer) one may be fixed
(unarticulated) (fig. 391, 392, 394, 400,402) or mov-
able (fig. 393,401) (articulated), but the upper (inner)
spur always is movable, normally longer. The lower
spur occasionally is modified into a twisted shape (fig.
395) or reduced to aborted (fig. 396, 500,402). The
shape of each spur is described as are their relative
lengths to each other and to the first tarsal segment.
Genitalia: Because there is no standard terminology
and there are several basic genitalia types, no lengthy
descriptions are attempted. However, figure refer-
ences for the various views are cited, and these should
provide positive means for identification ofboth males
and females.
5) Taxonomic Notes: Any information was in-
cluded here on synonymy, type specimens, questions
about validity, variability, etc.
6) Distribution: We provide maps, and reference
to them, for both Florida and the U.S. We have divided
them so that discussions on records are clearer. Florida
records are based on specimens examined only, unless
a specific questionable literature record is discussed.
All specimen data are either listed under SPECIMENS
EXAMINED (10 or less records) or in the Appendices
(10 or more records). The U. S. distribution was
basically plotted from the literature, but trying to
locate specific records in order to place dots accu-
rately. Questionable or unusual records are shown on
the map by a question mark.
7) Biology & Ecology: General remarks are given
first on such things as seasonal activity, abundance,
and other notes. These are followed by 2 subdivisions:
a) Adult Host Plants: These are primarily literature
records, normally with Luginbill & Painter's (1953)
list by family first. It is then followed by other host
records, usually by state, with author and date citation.
Few adult hosts were recorded in our study, partly
because of the apparent non-specificity of most spe-
cies and the ease by which they may be collected at
light; b) Immatures: The known larvae are described
from the literature. Little time or effort was spent on
rearing, so there is little original data here. However,
the pertinent literature is cited to aid the reader in
obtaining information.
8) Specimens Examined: For those species with
less than 10 records, the data are listed here; the others
are only summarized, with the total number and refer-
ence to the full data in the appropriate Appendix.
9) Selected References: Except for catalogues or
checklists, we have attempted to cite all references to

Historical Resume
The first list of Florida Phyllophaga was that
included in the "Coleoptera of Florida" (Schwarz,
1878). Six described species (latifrons, cerasina,
glaberrima, micansfraterna, and tristis), and 4 unde-
scribed species were recorded under the generic name
Lachnosterna. Dozier (1918) listed 5 described spe-

cies (prununculina, glaberrima, parvidens, latifrons,
and micans) and 1 undescribed species "near nova"
from Gainesville.
The first extensive list (29 species) was produced
by Blatchley (1929) in his "Scarabaeidae of Florida".
Young and Thames (1949) reported 41 species in their
"PreliminarylistofthePhyllophagaofFlorida". The
monograph on the 'May Beetles of the United States
and Canada" (Luginbill & Painter, 1953) contained
records of40 Florida species. In Part I of the "Scarab
Beetles of Florida", Woodruff (1973) listed 40 de-
scribed and 2 undescribed species of Phyllophaga.
In the present study we recorded 54 species,
including 2 new species, 9 new State records, and 2
species placed in synonymy; 16 additional species are
listed as questionable or potential.
Methods and Materials
Over 100,000 specimens of the genus Phylloph-
aga were examined for this study. Because the geni-
talia are the most reliable taxonomic characters, these
were normally dissected. Since many species are
extremely common, voucher specimens of these often
were preserved in alcohol (70% isopropyl) rather than
conventional pinning.
Genitalia: Dissection of genitalia from these large
beetles is an easy operation. The last ventral segment
and the pygidium are pried apart so that the genital
opening is accessible. Generally forceps are an ade-
quate tool to extract the genitalia on fresh specimens.
However, an insect pin or dissecting needle is handier
for females and alcohol preserved specimens. Dried
specimens must be relaxed in a humidity chamber, in
an ultrasonic machine, or in boiling water, prior to
dissection.
On specimens to be retained in alcohol, the geni-
talia were exposed sufficiently for identification, but
were left attached to the internal membranes. For
pinned specimens, the genitalia may be handled the
same way, but they often are mounted on traditional
triangular card points or preserved in microvials with
glycerine. Some minor cleaning of the male claspers
and the female pubic process may be required to see all
the features, but clearing with potassium hydroxide is
not required.
The male internal sac or aedeagus usually is
hidden within the basal piece and often requires everting
in order to study it. In some species (e.g., apicata,
bruneri, tristis, youngi, the sac is always somewhat
everted and normally visible without further dissec-
tion (fig. 4,59,64,119,124,179,184,239). Presently
most taxonomic characters are found on the para-
meres, but limited study suggests that excellent char-
acters may be found on the aedeagus. These may be
useful in clarifying some of the similar species, such as
the fraterna complex.
During our early studies we made microscope
slide preparations of these, but their 3-dimensional

shape was lost, and relative positions of characters was
obscured. In order to study them "in the round"
techniques were developed (by P. E. Skelley) to keep
the soft parts rigid. The sacs were everted either by
dissection with jeweler's forceps and hook-tipped
minutes (for previously dry specimens that had been
relaxed in detergent water), or by squeezing the sur-
rounding muscles to inflate the aedeagus by osmotic
pressure (for freshly killed specimens). The inflation,
especially on the relaxed specimens, could be in-
creased by injection of 70% isopropyl alcohol through
a hypodermic syringe.
Once inflated, they were dehydrated through several
changes of ethanol (80-90-100-100%). Dehydration
required at least 10 changes for fresh specimens (from
10-100%). They then were dried in a critical point
drier (Tousimis, Samdri 780A*), so that all parts
remained rigid and in place. They were mounted
finally on card points which were glued to a stub for
eventual study and photography under the scanning
electron microscope. Our studies are very preliminary
for the aedeagus, and we only illustrate a few to show
how significant they may be and to encourage their
future study (fig. 433-450, 583, 601, 602).
Illustrations: The genitalia are at a size range and
complexity that conventional photography is difficult
(particularly depth of field). No single view of the
male genitalia is adequate to clarify characters in most
species, and line drawings of several views each (about
380 required) were planned. However, the use of a
scanning electron microscope enabled us to prepare
much better and more detailed illustrations.
Specimens (genitalia) were cleaned in an ultra-
sonic cleaner, glued to an aluminum stub, and coated
with 24 karat gold (fig. 412) (approximately 150
angstroms thick) in an Eiko Engineering IB-2 Sputter
Coater*. They were placed then in the chamber of the
scanning electron [SEM] microscope (Hitachi S-450*)
with a camera attachment. Most study was done at 20
kilovolts, permitting a minimum magnification of 16
times. After specimens were oriented, they were
photographed on Polaroid (55 Professional, positive/
negative*) 4x5in. instant sheet film. Negatives were
developed and stored with the positive print for later
darkroom work. Scale lines (in microns) were pro-
duced automatically by the microscope and appeared
on the photographs. Over 1000 photographs were
taken, in order to obtain the final 548.
All final prints for the plates (1-35) were made
from the polaroid negatives, enlarged or reduced for
uniform size, and improved for reproduction, with
standard techniques in the darkroom (for which we are
greatlyindebted to JeffLotz). They then were cropped
to a uniform 2 1/4in. square for composition into the
plates.
Because the backgrounds of the SEMphotographs
were not uniform, obscuring certain features, we de-
veloped a technique for painting them black (see
beforeandafter, fig.413,414). The finishedproductis
therefore a combination of photography and artwork.
Painting was done on the photograph surface with fine
camel's hair brushes (0000 to 2), using the opaque
black water soluble paint (No. GY9) of a Gamma
Retouch Set (25/8, M. Grumbacher, Inc*.). Dirt and
damaged areas also were retouched with the other 7
shades of white and gray in this set. Over200 hours of
painting time were required.
The finished illustrations were mounted on heavy
stock in the format of the plates, using strips of double-
facedcarpet tape (Super Stick,Superior, Union, Mo*.).
Legends for the plates, scale lines, and the squares for
the illustrations were generated on a computer with
Aldus Pagemaker*. The scale lines were measured to
the nearest millimeter on the polaroid print and then
drawn to that length on the computer. The sheets with
figure legend, scale lines, and outlines of the squares
were used as an overlay negative by the printer to crop
the photographs uniformly, when combined with the
half-tone negatives. Windows, the size of the finished
half-tone areas, were made of ruby lith to match the
computer generated squares. Plates 1 to 34 were
finally reduced by 6%, but Plate 35 was reproduced at
original size.
Halftone negatives of 150 line screen, using the
Duo-tone process, were prepared by Storter Printing
Co., Gainesville; printing was done by Paramount-
Miller Graphics, Jacksonville, Florida.
Collecting Techniques
Perhaps this section might appear superfluous,
since even children can easily collect "June Bugs"
around the lights at night. Probably all the Florida
species are attracted to lights, if they are within a
reasonable distance of their habitat. Morethan95% of
our specimens were collected with blacklight (ultra-
violet) light traps of various design (see U. S. Depart-
ment of Agriculture, 1961).
However, many of the rare species either have
restricted habitats, or we know too little about them.
Some (e.g., taxodii on cypress) are so host specific that
special effort must be made to operate traps near the
host. In other cases (e.g., skelleyi in turkey oak scrub)
the general habitat must be located to collect speci-
mens.
Because they feed and mate at night (with the
possible exception of okeechobea), they are collected
easily from their hosts, with the aid of a headlight
(flashlights require a hand, and both are needed to hold
the container and to collect specimens). Beetles usu-
ally are so intent on feeding or mating that they are not
disturbed easily, and they may be picked like grapes.
Often more diversity and specimens may be collected
from foliage (in a comparable time period) than a light
trap in the same area. Usually we try to use both
techniques.
Specimens may be collected in killing jars with
cyanide, ethyl acetate, or lighter fluid, or they may be
preserved in alcohol (70% isopropyl preferred). Be-
cause they are large and exude body fluids on death,
the latter technique is better, providing adequate pro-
tection until genitalia can be dissected and specimens
can be mounted.

number may be found in Mexico and Central America.
Because there are so many species, generalities are
difficult to make. They occupy many ecological
niches, andevery major habitat(exceptaquatic) seems
to have been invaded. Since they are often economic
pests in both adult and larval stages, it is imperative to
know which of the many species is involved, so that
control strategies can be planned effectively.
Taxonomy: The United States fauna is fairly
well-known, partly due to the work of M. W. Sander-
son (1937-1958, and unpublished) and the faunal study
byP.LuginbillandR. H. Painter (1953). This is not the
case in other areas (e.g., Mexico and the West Indies)
where up to 50% of the species may be undescribed.
The Florida fauna was well-known previously, and the
2 new species described herein are the first in nearly 40
years.
However, the U. S. fauna was not always on such
a firm foundation. Historically, our species were
placed in numerous genera from 1781 until 1916 and
namedby 25authors. They are shown in chronological
order in Table 2. The name of the genus is firmly
established now, but past confusion about its validity
contributed to some homonomy and disagreement
among various workers. Glasgow (1916) provided a
detailed review of the confusion and was instrumental
in stablizing the name.
Briefly, the problems revolved around Harris'
(1827) original description of Phyllophaga in a foot-
note, which contained several valid species, but was
not accompanied by a description. The International
Rules of Nomenclature clearly recognize this as an
"indication", and the name should be recognized for
these insects. The type species, hirticula Knoch, was
chosen by Glasgow (1916).
The date of Harris' description has been listed
often as 1826 (e.g., Glasgow, 1916; Saylor, 1942). In
a later edition of the same book (Harris, 1863:30) he
again used a footnote to cite the original description as
follows: "A genus proposed by me in 1826. It
signifies leaf-eater. Dejean subsequently called this
genus Ancylonycha." However, in 1869 Scudder
published the "Entomological correspondence of
Thaddeus William Harris, M. D." and included a
complete list of his publications, giving the date of the
relevant paper as 1827. The reference was published
in the Massachusetts Agricultural Journal (Reposi-
tory), Volume 10, No. 1, on which the date July, 1827
appears. Harris may have referred to his 1826 date, on
the basis of letters (see Scudder, 1869:17) in that year
or when he submitted the manuscript, but the actual
date of publication should be 1827. However, that date
is of no apparent consequence in the synonymy.
Several prominent early workers (e.g., LeConte,
1856; Horn, 1887; Smith, 1889) believed that Phyllo-
phaga was not valid, because it was not accompanied
by a description. They used the generic name Lach-
nosterna Hope (1837), rejecting both Ancylonycha
Dejean (1833) andPhyllophaga on the same grounds.
In addition to Lachnosterna, LeConte (1856) also
recognized 3 new genera (Eugastra, Endrosa, and
Gynnis) and the Listrochelus of Blanchard (1850)
within what we now call Phyllophaga.
When Horn (1887b) published his monograph of
Lachnosterna, he suppressed LeConte's genera, as
wells Trichestesand Tostegoptera Blanchard (1850).
Saylor (1942) treated the genera related to Phylloph-
aga, establishing the following as subgenera: Phytalus
Erichson (1847), Listrochelus Blanchard (1850), Ch-
laenobia Blanchard (1850), Tostegoptera Blanchard
(1850), Eugastra LeConte (1856), Chirodines Bates
(1888). He also created 3 new genera: Triodonyx,
Clemora,andCnemarachis. Saylorlater(1937)raised
Chlaenobia to generic status, at the same time uniting
the Old World Brahmina Blanchard (1850) and Holot-
richia Hope (1837) with Phyllophaga.
Sanderson (in several papers and pers. com.) pre-
ferred to treat most of the "genera" as subgenera,
breaking them down into "species groups". This
avoids creation of homonomy and keeps the near
relatives together. There appear to be no sets of
exclusive characters which will suffice to segregate
the Phyllophaga relatives into clear cut genera (even
from different continents). Luginbill and Painter (1953)
avoided the problem in their treatment of the U. S.
species by not mentioning subgenera, eliminating the
species of the subgenera Listrochelus and Phytalus,
but including those in the subgenera Tostegoptera and
Eugastra (without reference to these names).
Moron (1986), treating the Mexican species, rec-
ognized the subgenera Phyllophaga, Phytalus, Listro-
chelus, Chlaenobia, Tostegoptera, Eugastra, and Tri-
odonyx, as well as species groups and "complejos"
within the groups. Thearrangements of Horn (1887b),
Boving (1942), Sanderson (mss.), and Moron (1968)
are summarized for the Florida species in Table 3.
The most important breakthrough in the taxon-
omy of this genus came with the discovery that the
genitalia of both sexes offered excellent characters to
distinguishotherwisevery similar species. These were
first used by Smith (1889b), when he illustrated the
genitalia as a supplement to Horn's (1887b) mono-
graph. Prior to that, some of the leading workers had
such difficulties in distinguishing species that they

described the opposite sexes as different species, placed
the same species in 2 genera under different specific
names, and generally added to the problem ofcorrectly
identifying the many species. Horn (1887b) stated that
"Lachnosterha is certainly one of the most difficult
genera in our fauna...," and Riley (1891) published a
paper entitled "On the difficulty of dealing with
Lachnosterna."
When Glasgow revived the name Phyllophaga in
1916, he also was able to establish the synonymy of
many species by reference to genitalia of most type
specimens available at that time. This provided the
nomenclatural stability which has greatly aided later
workers, but unfortunately Glasgow never published
his proposed monograph, nor illustrations of the geni-
talia as he planned.

Discussion: Because of the nature of the present
publication (faunal rather than monographic), it is not
appropriate to devote more space to the synonymy
than the basics listed above. More complete and
detailed accounts may be found in Saylor (1942),
Sanderson (1951),and Moron(1986). Thegenus name
Stenothorax Harris, 1827 (not 1826), has been listed by
some authors (e.g.. Moron, 1986; Riley, 1988) as a
synonym of Phyllophaga, but I have found no justifi-
cation for such treatment. The name was proposed in
the same footnote as was Phyllophaga, both being
coined for parts of the old genus Melolontha. How-
ever, Harris (1827:8) clearly stated that "Stenothorax
would be a good name for the subgenus having the
subspinosa for its type." (Riley, 1988:26 stated:
"Type species not designated"). The subspinosa,
referred to by Harris, is currently placed in the genus
Macrodactylus and has nothing to do with Phylloph-
aga.
Morphology
The dictionary definition of morphology involves
the form and structure of plants and animals. As such
it encompasses just about anything we can see on an
organism. Someone once said (and rightfully so) that
no species has been thoroughly or completely de-
scribed. The job of the taxonomist is to determine
which characters are important, of the thousands pos-
sessed by agroupoforganisms,andthenapply them to
the scheme of classification and to comparative stud-
ies.
Phyllophaga species are so similar in general
appearance that the normal comment of a casual ob-
server is: "they all look alike". That is only superfi-
cial, and the taxonomist is fortunate that excellent
distinguishing morphological features are found in
nearly all the species. The most distinctive structures
(the genitalia) happen to be hidden inside the abdo-
men, but they are extracted easily. Most of these have
been mentioned already in the Format of Presentation
and Taxonomy sections, and they are shown graphi-
cally in Table 8.

the taxonomic status of the sympatric, closely related
elizoria and okeechobea. After we finally sorted the
specimens to our satisfaction, we noticed that the label
data suggested a daytime activity for okeechobea
(none at light) and a nocturnal one for elizoria (nearly
allatlight). Although furtherobservations areneeded,
we believe that okeechobea is diurnal, and that this is
the species isolating mechanism that maintains the 2 in
the same locality (e.g., Archbold Biological Station).
Although there are probably some species of Phyllo-
phaga occasionally found in the daytime, we know of
only one other (Triodonyx n. sp., from Arizona; W. E.
Warner, pers. com.) which flies regularly during the
day. However, many of the relictual Melolonthinae
appear to be diurnal (e.g., Gronocarus, Hypothyce,
Phobetus, Polylamina, Thyce).
Attraction: May beetles obviously are attracted
to their host plants and to their mates. The nature of
these attractions (possible sex or aggregating phero-
mones) has received little attention, and we have not
studied them. However, the most notable attraction is
that to light (especially ultraviolet). This behavior has
produced nearly all of our specimens for study. Their
attraction to light was known to early workers as well,
and led to the control recommendation of suspending
a light over a tub of water with a layer of kerosene on
top. The nature of the attraction is still poorly under-
stood, although types of lights and height of light trap
location were studied by Chandler, et al. (1956). The
nature of the light attraction was the subject of a 10-
paper symposium (USDA, 1961), and various trap
designs were discussed by Hollingsworth,etal. (1963).
I have found that even the flightless cribrosa group are
attracted to lights in Texas.
Season: In northern states, most species appear in
May or June, giving rise to the common name. Even
though this generality holds for most species in many
areas, some species emerge in the fall, especially in the
desert areas of the southwestern United States. The
season often appears to be extended (both early and
late) in Florida, as can be seen in the records undereach
species. We have collected brunerievery monthofthe
year in Miami, but it appears to have 2 population
peaks (one in May-June, one in Aug-Sept.) and possi-
bly 2 generations per year.
Plant Hosts: Adult beetles feed on a great variety
of plant species in diverse plant families (see species
treatments under the heading "Adult Host Plants").
Most are found on broad leaved trees and shrubs, buta
few are primarily conifer feeders (e.g.,prununculina,
debilis, tacodii, and clypeata). The latter 2 species
appear to be host specific to cypress. Of those feeding
on the non conifers, they have such diverse hosts
(sometimes with different preferences in different
localities) that few generalities can be made. I studied
the negative and positive hosts for the introduced
bruneri in Miami (Woodruff, 1961) without finding
any pattern of plant families. Sometimes a close
relative (in the same genus) of good host would have
no beetles or feeding signs. The positive hosts and
their families are shown under bruneri in the species
treatments.
General Behavior: Other aspects not heated above,
but which had some discussion in the literature, in-
clude: proportion of the sexes (Chamberlin & Seaton,
1941); larval spatial pattern (Guppy & Harcourt, 1970);
oviposition (Sweetman, 1927); height of flight (Sh-
enefelt & Simkover, 1951); mite symbiosis (Jarvis,
1964); soil temperature influence on grubs (McCol-
loch & Hayes, 1923; species of a single host (haw-
thorn) (McCulloch & Hayes, 1922); and especially in
the following general references: Chamberlin, et al.,
1943-1941; Forbes, 1891b-1916; Hayes, 1925, 1929;
Hayes & McColloch, 1928; Ritcher, 1939-1958.
Immature Stages: Unfortunately we know less
than half the larvae for our Florida species, and only
the pupa of bruneri has been described (Woodruff,
1961). The known larvae are summarized in Table 4,
and they are treated in the following key. Taxonomic
characters are found primarily on the last ventral
abdominal segment (fig. 460) and the epipharynx (fig.
459). Space does notpermit a moredetailed treatment
here, but theknown larvae are described in detail under
each species. The primary references to larvae are as
follows: Boving (1937, 1942); Boving & Craighead
(1931); Davis (1913-1920); Hayes (1925-1929); Hayes
& McColloch (1920, 1928); Moron (1958); Peterson
(1951); Ritcher (1938-1967); Uhler (1941); Wade
(1935).
Phyllophaga pupae have rarely been treated, and
never in a taxonomic sense. Ritcher (1939) reviewed
the literature on the depth at which pupation takes
place. He found that some species (e.g., hirticula)
pupated deep in the soil, others (e.g., inversa) were
shallow, and most were intermediate (e.g., futilis).
Factors influencingdepth included the structure, drain-
age, and moisture of the soil,but they "did not change
the relative positions of the various species." Differ-
ences in latitude also had no effect on the depth for a
given species.
Moron (1986:163-168, fig. 281-287) described
and illustrated a typical pupa, the spiracles, and sexual
characters for a Mexican species (brevidens Bates).

Distribution and Zoogeography
Although different names have been used for
Phyllophaga in various parts of the World, we feel that
nothing is accomplished (and much is lost) by splitting
the group into genera purely on the basis of geography.
We therefore believe that Phyllophaga (sensu lato)
occurs in both Eastern and Western Hemispheres,
even though the European and Asiatic literature often
uses the names Lachnosterna, Holotrichia, and Brah-
mina.
With the above as a premise, we believe there are
probably more than 1000 species of Phyllophaga. We
have not studied Old World species, and little further
will be said about them here. In the New World, about
200 species are found in the United States, 254 in
Mexico (Moron, 1986), 80 in South American (Frey,
1975), and probably more than 150 in the West Indies
(Sanderson, pers. com. and Woodruff, unpublished).
Several checklists for the United States were
consulted for various reasons, but their short (and often
vague) distribution records were of limited use. However,
they are listed here for the benefit of the reader: Austin
(1880); Blackwelder (1939, 1957); Blackwelder &
Blackwelder (1948); Crotch (1874); Dalla Tone (1912);
Haldeman & LeConte (1853); Henshaw (1885, 1887,
1889, 1895); LeConte (1863); Leng (1920); Leng &
Mutchler (1927, 1933).

Within the United States, there have been many
state lists or faunal studies which give a general idea
of Phyllophaga species found therein. These are
variable in quality of both the collecting and the
knowledge at the time they were prepared. They are
listed alphabetically by state, with the number of
species in brackets, and with the author and date in
parentheses: Alabama [66] (Loding, 1945); Arkan-
sas [44] (Sanderson, 1944); Arizona [44] (Butler &
Wemer, 1961); Connecticut [13] (Britton, 1920);
Florida [42] (Young & Thames, 1949), [54] (present
study); Georgia [66] (Fattig, 1944); Illinois [34]
(Forbes, 1916); Indiana [26] (Blatchley, 1910); Iowa
[33] (Travis, 1934); Kansas [44] (Knaus, 1897);
Kentucky [36] (Ritcher, 1940); Louisiana [62] (Riley,
1988); Missisppi [45] (Langston, 1927b), [53] (Lago,
1980); Missouri [27] (Owens, 1950); Nebraska [25]
(Dawson, 1922), [+8] (Ratcliffe, 1974); New Jersey
[32] (Smith, 1910); New York [30] (Leonard, 1926);
North Carolina [39] (Brimley, 1938); North Dakota
[10] (Lago, et al. 1979); Ohio [36] (Neiswander,
1963); South Carolina [31] (Luginbill, 1928) [55]
(Kirk, 1969, 1970); South Dakota [17] (Kirk &
Balsbaugh, 1975); Texas [96] (Reinhard, 1950); Wis-
consin [18] (Chamberlin, et al., 1943)
We have attempted to provide detailed distribu-
tion records for Florida and also the United States
distribution for those recorded here. These are dis-
cussed under the DISTRIBUTION heading, and maps
are provided for Florida (the dots as near the localities
as possible) and the U. S. (general distribution area
outlined and indicated by shading; questionable rec-
ords are so indicated). We used Luginbill and Painter
(1953) as our basic source, but their maps and written
records were not documented by citations. Theirdots
usually appeared in the center of a state, although this
is misleading in several coastal species in the south-
east. We have tried to verify any unusual distribution
records, butwehavenot alwayssucceeded. Although
most of the major state lists are noted in the previous
paragraph, there are many smaller references, dealing
with only a few species. The several papers by Hatch
(1928,1929, 1941) are extremely useful as a starting
point for such a literature search.
In the Florida fauna, 3 species (bruneri, pube-
rula, andyoungi) are introduced from the WestIndies.
P. obsoleta has basically a Mexico-Central America-
South America distribution, just barely extending into
the United States, in Florida occurring only in the
panhandle. The following 8 species are recorded only
from Florida and may be precinctive (endemic): elizoria
Saylor, elongara Linell,floridana Robinson, okeechobea
Robinson, ovalis Cartwright, skelleyi n. sp., and tecta
Cartwright
Other New World references, by geographic area,
which may be useful in interpreting zoogeography of
Phyllophaga are: Central America (King, 1984; King
& Saunders, 1979, 1984); Cuba (Garcia-Vidal, 1975-
1987); Hispaniola (Sanderson, 1951); Lesser Antilles
(Chalumeau, 1983,1985;Chalumeau&Gruner, 1976);
Mexico (Moron, 1986); Puerto Rico (Wolcott, 1948);
South America (Frey, 1975); andWestIndies (Saylor,
1940).
Economic Importance
Few other groups of insects are as abundant and as
economic in both the larval and adult stages as are the
"white grubs" and "June bugs". Although we have
seen severe damage to sod and tree foliage in Florida,
ithasnotbeen asextensive asreportedelsewhere. Most
references discuss economic damage, but few have
quantified it. In addition to isolated economic reports
and those of a general nature, we have tried to summa-
rize, in the following paragraphs, some references with
meaningful figures.
Surprisingly,Luginbilland Painter(1953)devoted
little space to economics in their treatment of the U. S.
species. They mentioned that thousands of acres of
pasture in a single locality had the feed value reduced
by larvae, and the damage of white grubs to corn,
timothy, and potatoes (during peak years in the north-
central states) amounted to "... several million dollars
in a single year." They suggested that one reason, that
damage by adults in the south is seldom serious, is the
"... steady rise in temperature in the spring ... causes the
adult May beetles to emerge gradually."
Davis (1916a:270) gave more graphic data on
numbers. In May and June of 1914, he surveyed the
area of northern Illinois, Iowa, Wisconsin, and Michi-
gan, where he found "... the timber, which consisted
chiefly of oak and hickory, was completely stripped of
its foliage ... the beetles were so abundant that the dead
ones accumulating beneath the lights had to be swept
away each morning to prevent or at least modify the
terrible stench which they produced." The volume was
so great that "At one small town in Wisconsin the
beetles accumulating beneath the ten arc lights of the
town were hauled away each morning for period often
days or two weeks, by the wagon load."
In 1918, Davis provided more specific damage
figures for the heavy larval infestations of 1912 in
Iowa, Illinois, and Wisconsin. He estimated the damage
to corn, timothy, and potatoes in that area at $7,000,000,
and in other areas at $5,000,000. He also gave esti-
mates of larval populations in heavily infested areas at
106,680 per acre. In the fall (when they are well-fed),
he estimated that each grub weighed 1 gram (454 per
pound), and thus there were 235 pounds of grubs per
acre. He even recommended feeding them to hogs
because they had nearly the samepercentage offat and
protein per pound as corn (although deficient in carbo-
hydrates). Hisfigureoffoodvaluebeinggood at$3.00
per acre (presumably 235 pounds) is related to the
economics of the time, and can hardly be compared
with modem costs.
Forbes (1908:166) had earlier given statistics on
the quantities of grubs found in a 10-acre destroyed
cornfield in Illinois. By sifting the soil of each hill (3.5
ft. square) to a depth of 20 inches, he collected 3460
grubs per 100 hills, or "... about three hundred pounds
ofgrubstotheacre." Swine (100pigsabout75pounds
each and 8 large sows) were introduced into the field
on September 23, and by October 13 (20 days) the
entire 10 acres were rooted to a depth of 10 to 12
inches, and the grubs were reduced by 86% to4.8 per
hill. He did point out that the thorny-headed worm of
swine (Echinorhynchus gigas) uses white grubs as an
intermediate host, so that swine should not be used for
control where they have been pastured previously.
Forbes also mentioned hand collecting of adults as a
means of control. He quoted statistics from Sweden
(presumably for the related genus Melolontha) in a
ten-year period (1885-1895), when residents collected
29,736 bushelsofbeetlesata laborcost of$15554 (52
cents per bushel). They believed that this system
reduced the population from 14,801 (1887) to 5,611
bushels (1895), even though more collectors were
involved in 1895.
Since conifers are one of the most significant
elements of Florida forests, the species feeding on
them have an economic impact, however difficult to
assess. Grubs are known to damage pine nursery stock
(Baker, 1972,1985;Nairn &Wong, 1965; Shenefelt &
Simkover, 1951; Yeager, 1950), and adults of several
species damaged pine flowers in Louisiana (McLem-
ore, 1953).
Rolston and Barlow (1980) reported larvae dam-
aging sweet potato tubers in Louisiana sufficiently to
require preplanting insecticide treatment.
In Mexico, Moron (1986:7-8) reported a reduc-
tion of 1,314 kilograms per hectare of corn, due to
Phyllophaga larvae. He listed another case in the state
of Jalisco where grubs destroyed 13,784 hectares of
corn, beans, rice, and sorghum. Damage resulted in
the use of many insecticides over the years: Carbofu-
ran, Chlorfenvinfos, Chlorpirifos, DDT, Diazinon,
Foxim, heptachlor, Isofenfos, Protiofos, and Terbufos.
The use of such a chemical arsenal has had not only an
economic impact, but a profound effect on the envi-
ronment as well.
In Florida, sugarcane is the one specific economic
field crop which may be affected by white grubs.
Although grubs of other scarab genera are pests, appar-
ently the only species of Phyllophaga involved is
latifrons (Gordon & Anderson, 1981; Cherry, 1984-
1985; Sosa, 1984). The introduced species, bruneri, is
a known sugarcane pest in Cuba(Stahl & Scaramuzza,
1929), but it has not yet reached the Lake Okeechobee
sugarcaneregion. Because many speciesofPhylloph-
aga are sugarcane pests elsewhere, the following addi-
tional citations may be useful: Box (1953); VanDine
(1926); VanDine &Christenson (1932); Wade (1951);
Williams, et al. (1969); Wilson (1969).
Wolcott(1914-1948) devoted considerable atten-
tion to the white grubs as pests of sugarcane in Puerto
Rico, where they were once an economic threat. He
stated (1948:250) that they "... reached such a peak of
abundance as to become the decisive factor in deter-
mining whether the growth of sugarcane or any other
crop was possible." He further indicated that they "...
were the major insect pest of every crop grown ... in
bulk,... overbalanced all the other insects of the Island,
not only individually, but all other insects combined."
All this was before the introduction of the giant Suri-
nam toad (Bufo marines L.) which brings us to the next
section on natural enemies.
Natural Enemies
As pointed out in the previous section, these in-
sects can occur in tremendous numbers (wagon loads!).
When such populations explode, they are often fol-
lowed by some measure of control by natural enemies,
such as predators and parasites. We all know the story
of seagulls and grasshoppers in the history of the
Mormons in Utah.
From the economic viewpoint, we are fortunate
that there is an entire complex of such natural enemies
of the genus Phyllophaga. J. J. Davis (1919), the
author of the "wagon loads" quote, published an
extensive monograph on these natural enemies. We
have mentioned most of these under the species of
beetle parasitized or preyed upon. Because chemicals

known to feed on Phyllophaga, is too extensive to list
here, but involves many birds, mammals, and toads.

much larger than recorded, the following species are

Elateridae: Pyrophorus lumiiosus Illiger (Davis,
1919; Wolcott, 1948); P. havaniensis Castelnau (pres-
ent work).
Miscellaneous. The following groups of parasites
or predators are either minor ornon-insect and are only
briefly and generally cited here.
Mites: Davis (1919:102) recorded Rhizoglyphus
phylloxerae Riley, Tyroglyphus armipes Banks, and
Parasitus sp. on larvae, and Uropoda sp. on adults.
Jarvis (1964) discussed the association between a spe-
cies of Caloglyphus (Acaridae) and Phyllophaga anxia.
It was described as a new species by Oseto and Mayo
(1975). Fetch and Hammond (1925) listed hypopial
nymphs of Tyroglyphus sp. infesting 100% of white
grubs in one area in Quebec, but they found Rhizoglyphus
phylloxerae infrequently.
Parasiic worms: The helminth known as the thorny-
headed worm of swine (Echinorhynchus gigas) was
reported by Stiles (1892) to be secondary in white
grubs. It was discussed in detail by Glasgow (1926).
Hall (1929) discussed helminths and their intermedi-
ary hosts. Davis (1919) reported only a few larvae
infested with hairworms (Merminthidae) of the genus
Mermis (one of which was obtained at Pensacola,
Florida). Davis (1919) reported 2 species of nema-
todes in white grubs: Diplogaster aerivora Cobb and
Cephalobus(?) sp. Berberet and Helms (1969) studied
2 species of Eugregarina (Gregarina sp. and Actino-
cephalus sp.) in Phyllophaga anxia.
Spiders: Davis (1919) listed the following spiders
preying on adult Phyllophaga: Lycosa helluo Wakeman,
Xysticus gulosus Keys, and Plectana stellar Hentz.
Jennings (1974) discussed crab spiders preying on
scarab beetles. In our study, we found Phyllophaga
young being consumed by Nephila clavipes (Lin-
naeus), and P. skelleyi was trapped by Acanthepeira
marion Levi.
Toads: We cannot treat natural enemies without
considering the giant Surinam toad (Bufo marinus L.)
which has been introduced around the world to control
white grubs in sugarcane. Phyllophaga guanicana
Smyth, from Puerto Rico, is possibly extinct from this
toad's predation. Wolcott (1948) treated the success in
control of white grubs in Puerto Rico. Although the
toad was introduced into south Florida many years
ago, it does not seem to be extremely abundant and has
had no apparent effect on the Phyllophaga fauna here.
Protozoa: Little information is available on the
protozoan parasites which seem to be common and
play a commensal role in Phyllophaga white grubs.
Travis and Becker (1931) described and illustrated the
following from white grubs: Class Mastigophora
(Polymastix phyllophagae n. sp., Monocercomonas
melolonthae Grassi, Eutrichomastix passale Tanabe,
Eutrichomastix phyllophagae n. sp., Embadomonas
phyllophagae n. sp.). Class Rhizopoda (Arcella sp.,
Allantion sp.).
Diseases: Many types of diseases have been found
in scarab larvae, and some are available in commercial
formulations to use in control. Milky disease is one of
theimportantones(Dutky, 1941). Micrococcusnigro-
faciens Northrup, a bacterial disease, was considered
of minor importance in control (Davis, 1919). Several
fungus diseases of white grubs have been reported.
Metarrhizum anisopliae Metsch. (the green muscar-
dinefungus).Isaria densa Link (=Botrytis tenella) (the
white muscardine fungus), and Cordyceps melolonthae
Tulasne all were reported by Davis (1919). Isaria
vexans Pettit and Cordyceps melolonthae (Tulasne)?
were recorded by Pettit (1895). In Nova Scotia, Piers
(1889) reported a fungus from May beetle larvae
(probably Cordyceps melolonthae).

QUESTIONABLE AND POTENTIAL
RECORDS
In any study of this nature, dealing with thousands
of museum specimens and voluminous literature rec-
ords, errors are likely to be encountered. We have
included here those records for which we have some
doubts, specimens which have been intercepted at
ports and are potential introductions, and those which
we believe are most likely to be added to the Florida
faunal list. These are treated below, alphabetically
under each species. In addition, we must point out
what we believe to be a number of mislabelled speci-
mens (perhaps in othergroups of insects as well), all of
which bear the collector label F. W. Walker, mostly
1920 to 1922, and from Gainesville, Florida (mostly in
the University of Michigan Museum of Zoology). A
similar case, involving the same basic label data, was
encountered for another scarab of western origin
(Canthoan imitator Brown), which resulted in the erro-
neous description of a new subspecies floridanuss
Brown) based on this disjunct distribution (Woodruff,
1973:38-39). During the present study, we saw several
specimens with this data, some of which were well out
of the normal geographic range, including the only
Florida records for ilicis and ephilida, as well as the
only Gainesville records for georgiana and hirticula.
We are convinced that the above Walker speci-
mens, and potentially any with similar data, were
mislabelled. According to Dr. T. H. Hubbell (pers.
comm.), F. W. Walker was normally meticulous about
keeping field notes, for which a number was usually
attached to the pinned specimen. In reference to the
Canthon mentioned above, Hubbell stated "I think
your surmize that they were mislabelled is probably
correct, ... the chances are that Walker had nothing to
do with this material."
In general, we have had other specimens for which
we had good evidence or good reason to doubt their
validity. We have eliminated most of these from our
data bank without comment. Our basic philosophy is
that it is much more difficult to eliminate an error in
print than it is to addor clarify questionable records by
future collection or study. Some distribution records
perpetuated by Luginbill and Painter (1953) are im-
possible to refute or check because they gave no data
source for their maps or statements.
Two other incidents point out the possibility of
disassociating genitalia from the specimens, causing
confusion and, in one case, synonymy. Luginbill and
Painter (1953) used special "smoking" technique on
the genitalia to eliminate glare during photography, so
these specimens are easily recognized. Unfortunately
they did not reassociate the genitalia with the speci-
mens. Their figures and genitalia (which we have seen
in the USNM) for floridana are actually the new
species, pseudofloridana, but we could not locate the
beetles from which the genitalia were dissected.
The other incident was even more confusing.
Sanderson (1950) described murrea from a unique
female from Florida. He mentioned that it resembled
elongatla, but that the female genitalia were of a very
different type, comparing it to congrua. No further
specimens have ever been found that match this com-
bination. We borrowed the holotype from the UMMZ
and mounted it for the scanning electron microscope
photographs. Although we treated it as a species
during preparation of this manuscript, we are now
convinced that the body is that of elongata and the
genitalia are those ofclypeata, creating the new synon-
ymy.
Individual Species Discussions
Phyllophaga analis (Burmeister)
(=bifoveolata DuVal, subsericans DuVal)
Two specimens in the FSCA represent intercep-
tions of this Cuban species at Miami, Florida: (1) 19-
III-47,R. Baker, onSolanum melongenaLinnaeus var.
esculentum Nees, from Cuba, SPB Ace. #95342; (1) 1-
VI-56, F. A. Buchanan, from Cuba.
Chapin (1932:197-199, fig. 31) redescribed and
illustrated this species, recording itfrom the following
Cuban Provinces: Havana, Santa Clara, Camaguey,
andtheIsleofPines. Healsomentionedthat a pairwas
taken at Ancon, Panama, May 10, 1909, feeding on
marineses, the only Cuban species known to him
with a continentalrecord. Box (1953)andStahl (1929)
both listed it as a pest of sugarcane. There is no
evidence that it is established in Florida.
Phyllophaga cribrosa (LeConte)
Young and Thames (1949:126) recorded a speci-
men of this species from "?Orange County, H. T.
Townsend". Although they indicated that it was "...
very doubtful", they state "It may, however, occur in
the xeric sand areas of the Central Highlands of Flor-
ida".
Aside from the western distribution (Texas, Okla-
homa, New Mexico;fide Luginbill & Painter, 1953:51),
it is wingless and has limited dispersal powers. We
believe the specimen was mislabelled.
Phyllophaga dtssimilis (Chevrolat)
This Cuban species has been intercepted several
times at Miami, Florida: 6-VI-50, 11-VI-50, 24-VI-50,
all by J. E. Porter, on aircraft from Havana, Cuba
[INHS]; 5-VI-56,B. B. Sugarman, from Cuba [FSCA];
2-V-57, D. A. Miller, at Hibiscus esculentusLinnaeus,
interception No. M-10281, from Cuba [FSCA].
Chapin (1932:201-202, fig. 35) redescribed and
figured the species, recording it from the following
Provinces in Cuba: Santa Clara, Camaguey, and
Oriente. Other Provinces represented in the INHS
include: Havana, Pinar del Rio, and Matanzas. Box
(1953:9) listed it as apestof sugarcane in Cuba. There
is no evidence that it is established in Florida.
Phyllophaga drakii (Kirby)
Early in this study, we believed this species was
found in Florida. However, on further study, all
specimens proved to be eitherpostrema (fig. 44, 104,
164, 224, 257, 347, 350) or ulkei (fig. 56, 116, 176,
236,262,371, 374); two species with similar genitalia.
It is illustrated here (fig. 14, 74, 134, 194, 243, 283,
286) to aid in this distinction. *
Luginbill and Painter (1953:92-93) recorded it
from nearly all eastern states, except Florida. It is a
very large (av. 22mm long), dark species, often easy to
pick out from large collections of mixed species.
Phyllophagafraterna Harris
Several older lists (Blatchley, 1929; Young &
Thames, 1949) recorded this species for Florida. Because
of the similarity of several species in this group (e.g.,
curialis, floridana, foxii, incuria, mississippiensis,
paternoi, pseudofloridana), some of which were sepa-
rated only recently, these probably were misidenti-
fied. There appear to be no valid Florida records for
this species.
It is illustrated here (fig. 22, 82, 142, 202, 247,
300, 303) and distinguished from floridana (fig. 18,
78,138,198,244,293,296) andpseudofloridana (fig.
47, 107, 167, 227, 259, 353, 356). Sincefraterna is
recorded from nearly the entire eastern half of the
United States (Luginbill & Painter, 1953), additional
study is needed to clarify the species in this complex.
Phyllophaga glabricula (LeConte)
Although no specimens were seen from Florida in
the present survey, Luginbill and Painter (1953:60)
recorded it from "the prairie States of the United
States and also in Florida (fig. 54)." The other states
shown on their map are Colorado, Kansas, Nebraska,
Oklahoma, and Texas. Since we were unable to find
confirmation of this record 1) in the USNM (where
many of Luginbill & Painter's specimens reside) or 2)
in the extensive collection and records of M. W.
Sanderson at the INHS, and 3) this is a very unlikely
distribution to include Florida, we doubt this record.
It is possible that the "glabricula" was somehow
mistakenfor "glaberrima", a ubiquitousandcommon
species in Florida. The genitalia of glabricula are
quite distinct and were illustrated by Luginbill &
Painter (1953: pi. 53, fig. 6-11).
Phyllophaga hirtiventris (Hurn)
One specimen bf this species was intercepted at
Lake Buena Vista (Orange Co. Florida), 25-III-87, by
C. Phelps in a nursery, on Yucca recurvifolia Salis-
bury, from Houston, Texas.
It is treated and illustratedbyLuginbill and Painter
(1953:57-58, pl. 53, fig. 1-5) and was considered
common in some areas. However, no specimens were
recorded from Florida, and no others were found
during our survey. Fattig (1944:17) recorded a single

Georgia specimen from Tate, 27-VI-1932. Except for
that record, it appears to be distributed primarily in the
central part of the United States (i.e., Arkansas, Indi-
ana, Iowa, Kansas, Kentucky, Louisiana, Mississippi,
Missouri, Nebraska, Oklahoma, and Texas). The male
and female genitalia are similar in general shape to
latifrons, but distinct in specific characters.
Phyllophaga hondura Saylor
Three specimens of this Central American species
were found at a nursery in Apopka (Orange Co.,
Florida), 13-V-85, P. Gibson, in unrooted cuttings of
devil's ivy or golden pothos (Epipremnum aureum
(Linden & Andre) Bunt.), shipped from Honduras.
One of these was still alive when it was received in
Gainesville for identification.
The species is known from Honduras, Belize
(British Honduras), and Costa Rica (Saylor, 1943). In
Honduras, King (1984) found it common in areas with
between 1000 and 2000mm annual rainfall (normally
with a 2 year life cycle); he illustrated the genitalia
(fig. 5, p.44). Although there is no evidence that it is es-
tablished in Florida, the increased flow of plants from
Central America in the nursery industry, and the inter-
ception mentioned above, indicate the probability of
introduction.
Phyllophaga hubbelli Cartwright
This species may occur in northern Florida. It was
described from 3 specimens (1 male, 2 females) taken
in: Alabama, Calhoun Co., Oxford, 1.5mi. S., 18-VII-
38, Hubbell and Friauf (misspelled Freauf in original
description) [USNM, 1 male]; Georgia, Summerville,
4-VIII-37, P. W. Fattig, on hickory andred oak [INHS,
2 females]. No additional specimens have been re-
ported for this rare species. The distribution suggests
that it may be found in the panhandle of Florida.
Phyllophaga lobata (Fall)
There is a single specimen in the FSCA with a very old
handwritten label, indicating "Jackson Co., Fla.",
probably from the University of Florida Agriculture
Experiment Station collection; undoubtedly misla-
belled. A rare species found only in Arizona. It is
treated and illustrated by Luginbill & Painter (1953:19,
pl. 21, fig. 1-5).
Phyllophaga lodingi Sanderson
A single specimen in the FSCA is from Alachua Co.,
17-1-36, with no collector or specific locality. The
label is similar to that used for student collections at
the University ofFlorida; undoubtedly mislabelled. A
rare mountain species from Madison Co., Alabama. It
is treated and illustrated by Luginbill & Painter (1953:82-
83, pl. 62, fig. 8-14).
Phyllophaga omani Sanderson
This rare species is a member ofthe subgenus Phytalus
and is similar in appearance to georgiana and gracilis.
It is known from 7 specimens: Alabama, Bumsville,
20-VII-30, P. W. Oman holotypee, female); Georgia,
Prattsburg, 24-VII-30, R. H. Beamer, at light (al-
lotype, male); Georgia, Thomasville, 28-V-38, W. H.
Thames, Jr., on crab apple (1 male) [INHS]; "North
America" (Saylor, 1939:162-163; pl. 9, fig. 2a-e; 1
male); Mississippi, Biloxi (Lago, 1980; 1 male); Aiken
Co., South Carolina (Riley, 1988; 1 male); and Louisi-
ana, Washington Parish, Lee Memorial Forest, near
Sheridan, 7-VIII-85, C. B. Barr, mercury vapor and
blacklight sheet (Riley, 1988; 1 male).
Nothing else appears to be known about the spe-
cies. The record from Thomasville, Georgia, suggests
that it may occur in Florida. It was treated and the
genitalia illustrated by Saylor (1939:162-163, fig. 2a-
d).
Phyllophaga onchophora Chapin
A single specimen of this Cuban species was
found at Savannah, Georgia, by P. W. Fattig, at light.
The date was recorded by Sanderson (1942:42) as
"May 2,1929", butFattig (1944:31) listed itas "May
21,1929" andmisspelledthenameas "anchophora".
The species was described from 5 specimens
from the following localities in Cuba: Paso Estancia;
Trinidad, Santa Clara; Santiago de las Vegas, Havana;
Perico, Matanzas. Since 2 other West Indian species
youngi Cartwright and bruneri Chapin) are estab-
lished in Miami, another (puberula) was collected
once in Miami, and onchophora was found in a Geor-
gia port, it eventually may be found in Florida. It was
treated and the genitalia illustrated by Chapin (1932:184,
fig. 18).
Phyllophaga portorlcensis Smyth
A single specimen of this Puerto Rican species was
takenatPalm Beach Co.,Florida, Delray Beach, 17-V-
79, K. Stolley, on Dracaena deremensis Engl., from
Puerto Rico. It was intercepted live in a shipment of
plants, but is not likely to be established in Florida.
Along with the similar Phyllophaga vandinei Smyth,
this is the most economic species of Phyllophaga on
sugarcane in Puerto Rico (Wolcott, 1948:255-262;
Box, 1953:9). It is another member of the subgenus
Cnematachis.
Phyllophaga rugosa (Melsheimer)
A single, badly damaged, male specimen has the
label data: Florida, Alachua Co., Gainesville, Chan-
tilly Acres, 11-VI-68, F. S. Blanton, mosquito light
trap. Although this is a common species in the north-
east and midwest, it is not recorded from the tier of
states north of Florida (Luginbill & Painter, 1953: fig.
76). Additionally, hundreds of light trap samples over
30 years in Gainesville, and many from Chantilly
Acres, have produced no further specimens.
Because of the above, and knowing that the
collector operated traps in New York also, this appears
to be a label error. It probably is not found in Florida,
but for aid in identification, refer to the genitalia
illustrations in Luginbill & Painter (1953: pl. 71, fig. 6-
12).
Phyllophaga submucida (LeConte)
The only published Floridarecord for this species
is Luginbill and Painter (1953:29, fig. 17). Their
distribution map is similar to that for glabricula (an-
other questionable Florida record); including Arkan-
sas, Kansas, Missouri, Oklahoma, and Texas, with no
records for the tier of states north of Florida. We were
unable to verify the source for any Florida specimens
(including pers. comm. with M. W. Sanderson), and
we do not believe it occurs here. The genitalia were
illustrated by Luginbill & Painter (1953: pl. 33, fig. 1-
6).

Lachnosterna aemula Horn 1887b:271.
Phyllophaga aemula, Glasgow 1916:373.
TYPE LOCALITY: "northern Georgia".
DIAGNOSIS: Superficially it is similar to the follow-
ing hirsute Florida species (see genitalia figures in
parentheses for comparison): crenulata (male: 9, 69,
129,189; female: 275,278); elizoria (male: 15,75,135,
195; female: 287,290); ilicis (male: 29, 89, 149, 209,
250; female: 313, 316); mariana (male: 36, 96, 156,
216; female: 329,332); parvidens (male: 42, 102, 162,
222; female: 342, 345); and skelleyi (male: 51, 111,
171, 131; female: 360, 363).
In addition, aemula and parvidens have pruinescent
elytra under the pubescence, whereas crenulata does
not. In male ilicis the body is narrower, the antennal
club is longer, and the lower tibial spur is fixed. The
male genitalia of aemula have the bottom of the claspers
projecting, but in crenulata they are gently rounded.

tral), 266 (lateral). Male Genitalia: fig. 1 (caudal), 61
(ventral), 121 (dorsal), 181 (right lateral).
TAXONOMIC NOTES: A fairly uniform species,
with no synonyms having been created. Variation was
noted primarily in body color (from light to dark or
reddish brown). As with crenulata, the pubescence
sometimes appears more noticeable, due to the thick-
ness of individual setae and partial removal from wear.
The holotype male (Type No. 3683) and paratype
female (No. 3683), labelled "Ga.", from the Horn
collection, were examined at the MCZC; both have the
genitalia dissected. Also in the Horn collection are: (2)
"Haulover, Fla., March, 364", and (1) "Horn Coll. H
10259."
U.S. DISTRIBUTION (fig. 465): Luginbill & Painter
(1953: fig. 11) recorded it from Alabanma, Arkansas,
Florida, Georgia, Mississippi, New Jersey, North
Carolina, Oklahoma, South Carolina, and Virginia.
In addition, Reinhard (1950:37) recorded it from Texas
(Brazos Co.), and Riley (1988: map 2) recorded it from
Louisiana (8 localities in 7 parishes).
The Arkansas record was based on 1 specimen
from Crawford Co. (Sanderson, 1944:21). Smith
(1910:319) saw only 1 from New Jersey (DaCosta).
Loding (1945:105) listed 8 counties in Alabama, and
Langston (1927:63) listed 9 records from Mississippi.
Cartwright (1934:268) saw a single specimen from
Clemson, South Carolina. Although the type locality
is "northern Georgia," Fattig (1944:27) saw only 5
specimens in his extensive Georgia survey (Albany,
Head River, Thomasville).

FLORIDA DISTRIBUTION (fig. 464): Our south-
ernmost record is Ocala (Marion Co.), and it probably
occurs from there north and west to include the entire
panhandle. Smith (1889b:518) reported specimens
from Haulover, Florida collected by Schwarz, and
these are the basis for Blatchley's (1929:69) record
from "Haulover (Sz. Ms. and Fall)". He apparently
saw no Florida specimens. We believe these specimens
may be a misidentification and represent one of the
elizoria complex. Young and Thames (1949:128)
dO""'
repeated Blatchley's record and added: "locally common
in northern part of state."
BIOLOGY & ECOLOGY: Luginbill & Painter
(1953:20) listed the adult season as May to July. Our
earliest Florida record was April 18 (Florida Caverns
State Park) and the latest was October (Gainesville). At
Gainesville it was most abundant in July and August.
There is a curious note on behavior by Schwarz
(1891:241) which follows: "In 1875 while in camp at
Haulover Canal, in Florida, I had occasion to observe
Lachnosterna aemula, which in the earlier part of
March was flying about after dark, but also in the early
morning, when it was still so dark that the flying beetles
could only be heard but not seen."
Smith (1889b:518) erroneously cited this reference
to read "... Haulover, Fla., March 11-13 ... they fly
shortly before sunrise, instead of at dusk and early
evening, as do most of the other species." [italics ours].
The identity of Schwarz's specimens is in doubt, since
we have not found aemula that far south, and in 1891
the 2 species that we suspect he had (elizoria or oke-
echobea) were not yet described. However, the reference
to a species having early morning flight gave us another
clue to the habits of the rare okeechobea (see discussion
under that species).
Adult Host Plants: Beech, ebony, pine, rose, willow
[families] (Luginbill & Painter, 1953:20); cypress, pine
(Langston, 1927b:63); willow oak (Sanderson, 1944:21);
red oak, persimmon (Fattig, 1944:27); pecan, grape
(Reinhard, 1950:47); dogwood (Riley, 1988:72).
Immatures: Only the first instar larva has been de-
scribed, and care should be used when comparing it
with the third instar of other species (e.g., in our Key).
On larval characters, Boving (1942:29-30, fig. 2, 8)
placed it in his group 1, along with crenulata, rubigi-
nosa, and parvidens. His description follows: "Poste-
rior part of labrum with no setae. Anterior marginal
region of frons with 2 setae on each side. Epicranium
on each side opposite concave posterior part of frontal
suture and epicranial suture with 2 setae. Dorso-molar
region of right mandible (Fig. 4) with an oblique series
of about 5 setae at the anterior part of mola and 15 to 20
setae in a patch behind; dorso-exterior region with a
few punctures or usually bare; scrobis with a longitudi-
nal row of 6 punctures; ventro-lateral carina without
setae. Maxillary articulating area ventrally with about
5 short, thick, dark granules (Figs. 2, 6). Epipharynx
with 5 large heli in a distal row and 2 short ones in a
proximal row. Proplegmatium (Fig. 5) distinct, subel-
liptical, moderately wide with 7 to 10 preplegmata;
chaetoparia with few, usually setula-bearing punc-
tures; crepidal punctures about 4. Raster (Fig. 8) with
inversely spatulate septula; each palidium with one
irregular row of from 25 to 27 straight, sharply pointed,
moderately long, densely set pali; preseptular setae
about 12, long, and arranged in three very irregular
transverse rows. Hatching spine (Fig. 3) represented by
a weakly sclerotized, thin, yellowish plate."
SPECIMENS EXAMINED: 450 from the following
9 Florida counties: Alachua, Gadsden, Jackson, Jeffer-
son, Leon, Liberty, Marion, Santa Rosa, and Wakulla.
Over 255 specimens, representing 111 records, were
from Gainesville. For complete data, see Appendix 1.

TYPE LOCALITY: no specific locality, but pre-
sumed to be "Lake Superior".
DIAGNOSIS: Superficially itis similar to several dark
glabrous Florida species, but is easily distinguished by
the genitalia. As a member of thefusca group, the male
genitalia are asymmetrical (but only mildly) (fig. 2,62,
122, 182, 241), and the female genitalia (fig. 264,267)
have a distinct transverse fold on the basal plates. Of
Florida species, genitalia are similar only to implicita
(male: 30,90, 150,210,251; female: 317,320). However,
that species has 9-segmented rather than 10-segmented
antennae.
DESCRIPTION: Length: 17.2-22.5mm (23.6mm,
Riley); Width: 9.3-11.6mm (12.6mm, Riley). Shape:
oblong, ovate, subdepressed. Color: dark brown to
black. Vestiture: glabrous, moderately polished. An-
tenna: 10-segmented; male club length nearly equal to
stem. Clypeus: emarginate; border moderately reflexed.
Tarsal Claws: tooth strong, median. Male Posterior
Tibial Spurs: lower fixed, half length of upper. Female
Genitalia: fig. 264 (ventral), 267 (lateral). Male Geni-
talia: southern form: fig. 2 (caudal), 62 (ventral), 122
(dorsal), 182 (right lateral), 241 (left lateral); northern
form: fig. 3 (caudal), 63 (ventral), 123 (dorsal), 183
(right lateral), 242 (left lateral).
TAXONOMIC NOTES: With the 7 synonyms listed
above, it is obvious that there has been much confusion
about anxia. Variation in body size and in genitalia are
noticeable. Two distinct types of male genitalia (north-
ern and southern forms) are recognized (fig. 2,3,62,63,
122, 123, 182, 183, 241,242). Our few Florida speci-
mens are clearly the southern form. It has the widest
distribution of any U.S. species. Luginbill & Painter
(1953:80) mentioned that Utah specimens are half the
size of those from other parts of the country.
Space does not permit a thorough accounting of the
above synonymy, which was established by Glasgow
(1916:371). This is one of the species which needs
more detailed study, especially the internal sac, to
clarify the extensive variation.
U.S. DISTRIBUTION (fig. 467): Luginbill & Painter
(1953: fig. 73-74) recorded it from every state except
Arizona, California, Florida, Nevada, West Vir-
ginia and Wyoming. They also list 11 provinces in
Canada, making this the widest distributed of all U.S.
Phyllophaga.
FLORIDA DISTRIBUTION (fig. 466): The 4 Flor-
ida specimens were all taken at Torreya State Park
(Liberty Co.), the source for several records of northern
species in this relictual area along the Apalachicola
River. These are the first Florida records.
BIOLOGY & ECOLOGY: Because there is a north-
ern and southern form, based on genitalic differences,
some of the references to biology may refer to one or the
other. Our 3 Florida records are for April, May, and
July.
Forbes (1916:227-228) called it a distinctly northern
species in Illinois where it apparently has a 3-y;ear
cycle, collected as early as April 15 and as late as July
8. In North Carolina, Brimley (1938:203) reported
collecting it in the ground or under stones or logs in
winter and early spring. Hayes (1929:66) cited a report
that it had a 4-year life cycle in Manitoba, Canada.
Because of its economic importance and its widespread
distribution, there havebeen more studies (and resulting
publications) on this species than any other in the U.S.
Space permits only citing the references by subject
matter as follows:

Immatures: The third instar larva was described by
Boving (1942:44, fig. 114-116), who places it in his
group 16, along withfusca, vehemens,fervida, margi-
nalis, and drakii (based on larval characters). His
description follows: "Posterior part of labrum with a
tranverse series of 5 to 7 long setae on each side.
Anterior marginal region of frons with a transverse,
somewhat irregular series of 5 to 7 setae on each side.
Epicranium on each side opposite posterior concave
part of frontal suture and epicranial suture with 3 or 4
setae. Dorso-molar region of right mandible (Fig. 116)
with a patch of about 30 setae; dorso-exterior region
with either from 3 to about 10, or from about 20 to 25
punctures; scrobis with about 7 punctures in an irregu-
lar, longitudinal row and occasionally with a single or
2 to 3 setae; ventro-lateral carina with 6 to 8 setae; baso-
lateral region with a patch of about 8 setae and some
punctures. Epipharynx with about 12 heli; propleg-
matium rather broad, long and spatulate with 11 to 15
curved proplegmata; right chaetoparia with numerous
punctures among the setae; crepidal punctures about
25. Raster (Fig. 115) with anterior third of septula oval,
tapering posteriorly into a subrectangular part; palid-
ium with one very irregular, in places double row of pali
numbering from 20 to 30 or more; palus (Fig. 114)
compressed, with concave sides and hooked at the tip;
majority of pali separated by a distance half as long as
a palus or shorter; preseptular setae 6 or more. (Length
of body about 40 mm.; width of head about 5.5 mm.)."
Ritcher (1966:87-88) included it in his key, but
included no illustrations.

Phyllophaga tristis apicata Reinhard 1939:58-59.
Phyllophaga apicata, Sanderson 1944:20.
TYPE LOCALITY: "College Station, Texas".
DIAGNOSIS: This and tristis are the only small (10-
13mm long), yellowish brown, hairy species in Florida.
These two are difficult to distinguish except by the
aedeagus (internal sac) of the males (females can be
identified only by association). In apicata (fig. 4, 64,
124, 184) there are 2 apical aedeagal processes; the
dorsal toothed near the apex, the distal process single
bladed, looped downward, then curved upward and
with apex entire.

fig. 473. Phyllophaga tristis: aedeagus (right lateral view) (5mm
= 0.05mm).
DESCRIPTION: Length: 10.0-13.0mm; Width: 5.2-
6.5mm (7.3mm, Riley). Shape: oblong, slightly wider
behind. Color: rufotestaceous. Vestiture: pubescence,
long, erect on head and pronotum, shorter, suberect on
elytra; surface more shining than in tristis. Antenna:
10-segmented; male club shorter than stem. Clypeus:
entire, rounded to nearly straight medially; margin
broad, strongly reflexed. Tarsal Claws: tooth small,
antemedian, acute. Male Posterior Tibial Spurs: lower
movable, slender, obtuse, longer than first tarsal segment.
Abdomen: fig. 403 (venter). Female Genitalia: fig.
265 (ventral), 268 (lateral). Male Genitalia: fig. 4, 5
(caudal), 64, 65 (ventral), 124, 125 (dorsal), 184, 185
(lateral).
TAXONOMIC NOTES: This form was originally de-
scribed as a subspecies of tristis, along with amplicor-
nis and suttonana. These are now considered species,
although they are similar and confused in all literature
before 1939. The tristis complex has an extremely
broad geographic range and extensive external vari-
ation in vestiture. The only secure characters for
distinguishing the forms are in the aedeagus (internal
sac) of the male genitalia (fig. 468,470,471, vs. 469,
472,473). Females of all forms are presently insepa-
rable. The complex needs a thorough evaluation from
its entire range and an examination of the Fabrician
type of tristis.
U.S. DISTRIBUTION (fig. 475): Reinhard (1939:59)
listed paratypes from: Alabama (Mobile, Auburn);
Arkansas (Cody's Gap); Georgia (Zebulon, Perry,
Rome); Kansas (Tonganoxie State Lake); Kentucky
(Paducah); Maryland (Takoma Park); South Carolina
(Walhalla, Chappells, Florence); Texas (College Sta-
tion, Atlanta, Smith Co.); Washington, D.C. Riley
(1988:86) listed it from 6 parishes in Louisiana.
This is a wide and spotty distribution which needs
clarification by further collections. Many of the older
literature records for tristis possibly refer to this species.
Luginbill and Painter (1953: fig. 19) show tristis from
the eastern two thirds of the U.S.
FLORIDA DISTRIBUTION (fig. 474): The only
definite records are from Alachua Co. and Union Co.
Older Florida records of tristis by Blatchley (1929:70)
from Haulover and Ft. Barrancas need to be reexam-
ined in the light of the several species now in the tristis
complex. Young & Thames (1949:128-129) recorded
tristis as "not uncommon around Gainesville' (proba-
bly all apicata) and "in western parts of the state"
(probably true tristis).
BIOLOGY & ECOLOGY: Reinhard (1941:526-532)

College Station, Texas) and compared it with other

curved; tooth triangular, median, stouter than apical
portion. Male Posterior Tibial Spurs: lower movable,
two-thirds length of upper; longer spur twice length of
first tarsal segment. Abdomen: fig. 404 (venter). Female

talia: fig. 6 (caudal), 66 (ventral), 126 (dorsal), 186
(right lateral).
TAXONOMIC NOTES: This introduced Cuban spe-
cies has no synonyms. Saylor (1942:159) created the
genus Cnemarachis for most of the West Indian species
of Phyllophaga. Sanderson (1951) treated it as a
subgenus. Variation in the claspers was described and
illustrated by Woodruff (1961:15, fig. 25). It is related
to suturalis (Chevrolat), aeruginosa (Burmeister), micro-
soma Chapin, aeneotincta Chapin, and alquizara Chapin
(all Cuban species).
I examined the holotype male labelled: USNM
Type 43800, Cuba, Santiago de las Vegas, Havana, 14-
VI-1921, B. T. Barreto, and compared it with Florida
specimens. They are conspecific in all respects, including
the genitalia. The allotype female was described by
Woodruff (1961:16, fig. 11) with the following label
data: Miami, Florida, 28-IV-60, P. E. Briggs, blacklight
trap (FSCA). Because the female was not known to
Chapin when he originally described the species, and
because of the importance of the genitalia in establishing
the identity of both males and females, it was deemed
important to create the allotype as a point of reference.
Even though this was more than 30 years after the
original description, it complies with the original definition
of the term allotype (see Fernald, 1939).
U.S. DISTRIBUTION (fig. 479): This introduced
Cuban species is known in the U.S. only in Florida.
Agricultural inspectors (pers. com.) at the Arizona
border have intercepted it several times in vehicles
originating in Miami, Florida.
FLORIDA DISTRIBUTION (fig. 478): Originally
found only in Miami (Woodruff, 1959, 1960, 1961), it
has spread to 3 counties; Broward, Collier, and Dade
(see Appendix 3 for complete data).
BIOLOGY & ECOLOGY: Considerable work was
done on this Cuban species shortly after it was intro-
duced into Florida about 1959. It is now well estab-
lished, and in the 30 succeeding years it has spread to
both coasts. This species is a known pest of sugarcane
in Cuba, but it has not yet been found in the sugarcane
growing regions around Lake Okeechobee. It has been
the subject of a Master's thesis (Samol, 1968) and a 2
year USDA, ARS grant (Habeck & Wolfenbarger,
1968). The following resume' is taken from personal
observations, along with data from the above refer-
ences.
Egg production varies greatly, but averages about
12 per female. No specimens have been reared from
egg to adult, and no definite larval food has been
established. Presumably they feed on grass roots.
Adults are found during the day, within the top 3 inches
of soil; larvae in the upper 6 inches. Average head
capsule width for the 3 larval instars is as follows: 0.95,
1.56,2.47mm. Two peaks of adult activity occur (86%
April, May, June; 12% August, September, October),
although adults emerge every month of the year. The
greatest number taken on one night in a blacklight trap
was 58,400 on May 12, 1965. Adult evening flight
takes place primarily at about 25 minutes after sunset,
with less than 1 foot candle of light. Their return from

the foliage to their hiding places occurs early in the
morning during a brief 15 minute period (6 to 6:15a.m.
on May 17-19). Duration of copulation averaged 21.6
minutes (17 to 26).
The giant Surinam toad, Bufo marinus Linnaeus,
fed on adults. The larvae of a luminescent click beetle,
Pyrophorus havaniensis Castelnau, were found feeding
on larvae. Adult click beetles of this species were
collected by the hundreds (it was previously rare) in the
same light traps with the Phyllophaga.
Within 2 years of its discovery (June, 1959) in
Miami, it had occupied an area of about 10 square
miles. It was not seen at the Subtropical Experiment
Station (near Homestead) until 1968. It was first found
at Ft. Lauderdale in 1977 and on the west coast at
Naples in 1986.
In addition to the list of positive hosts above, a list
of 36 negative hosts was provided (Woodruff, 1961:
