MALARIA IN FLORIDA 12
D. B. LIEUX
CDC Entomologist, Division of Entomology, Florida State Board of Health
Jacksonville, Florida
During recent years, the principal approach to malaria con-
trol and prevention in Florida has been the DDT residual spray
program. Initiated in 1945, this activity was a cooperative one,
with the Florida State Board of Health, local health depart-
ments, and the U. S. Public Health Service participating. The
program involved spraying of walls, ceilings, porches, and privies
of unscreened or poorly screened houses with DDT in those
areas whose epidemiological history showed a high incidence of
malaria. The effectiveness of these treatments has been de-
termined principally by their ability to maintain houses free
of the malaria vector. The tendency of malaria mosquitoes to
rest and linger within houses, especially after a blood meal, has
been well established and it is this characteristic which results
in control by means of the interior residual spraying of homes.
Evaluation of control operations was based on inspections made
in both sprayed and unsprayed houses. These data, during the
period control operations were conducted, showed that an aver-
age of 97 percent of the sprayed houses inspected were found
to be free of Anopheles quadrimaculatus as compared to 68 per-
cent of the unsprayed houses inspected. Through 1950, 313,081
houses in forty counties of Florida have been treated. In addi-
tion to enhancing malaria control and prevention, these treat-
ments have simultaneously yielded a high degree of control of.
other house-frequenting insects. While the concurrent control
of houseflies since 1948 has been relatively poor, apparently due
to resistance to DDT, there is no evidence to indicate that ano-
phelines have developed any significant degree of resistance to
this insecticide, under field conditions.
Reported cases and deaths from malaria in Florida during
the period 1917 through 1949 are shown in Figure 1. The peak
year of reported cases appears to have occurred during 1919,
when 1,895 cases were reported. During 1929, a record 470
deaths from the disease were reported. The graphs indicate a

cyclic decline, during the period observed, the exact cause or
causes for which have never been clearly demonstrated. Judicious
speculation may attribute this decline in malaria to a combina-
tion of factors difficult to accurately evaluate. Undoubtedly the
economic status of the population has played an important role,
greatly influencing the individual's ability to purchase house-
hold insecticides, to provide screening and other protective
measures, medical care, and physical resistance commensurate
with the standard of living. During and following the depres-
sion years, extensive drainage projects were conducted by Fed-
eral relief agencies which resulted in a quantitative reduction
of the malaria vector. Improved education and regulatory
measures, pertaining to water impoundments, likewise appear
to have enhanced this decline. Substantial increases in reported
malaria cases during 1944 and 1946 may be attributed to "im-
ported" malaria, principally involving armed .forces personnel.
The DDT residual spray program may logically be presumed to
have materially assisted in preventing a resurgence of malaria
during and subsequent to this period.
Due to the present low incidence of malaria in Florida, the
Public Health Service has withdrawn financial support of county-
wide DDT residual spray programs. To supplant this, a malaria
surveillance and prevention program is contemplated for the
Fiscal Year beginning July 1, 1951. In each of the thirteen
Southeastern States, where malaria has not been eradicated, the
Communicable Disease Center of the Public Health Service pro-
poses to organize, in cooperation with the States, federally sup-
ported malaria surveillance and prevention teams whose primary
responsibilities shall be the prevention and elimination of ma-
laria. Ideally, a team shall consist of an epidemiologist, an ento-
mologist, and an engineer.
RESPONSIBILITIES OF THE EPIDEMIOLOGIST: The epidemiolo-
gist should investigate and appraise each case of malaria in the
State as soon as feasible. Cases should receive the following
priority in investigation:
a. Laboratory confirmed cases.
b. Cases reported from areas known to have been previously
malarious and cases reported by doctors known to have
given bona fide reports in the past.
c. Rumors and unofficial reports of malaria.
d. Other malaria reports.
133
THE FLORIDA ENTOMOLOGIST
The determination of priority investigation in any of the above
categories should be the responsibility of the state epidemiolo-
gist. If appraisal indicates the possibility of recent local trans-
mission of malaria, immediate steps should be taken to determine
the source and the extent of spread of the infection, specifically
by house to house epidemiological investigation and thick film
surveys. After epidemiological appraisal has located a positive
or presumptive case, the epidemiologist should make available
his findings and interpretations to the other members of the
team for appropriate control procedures.
A continuing and primary responsibility of the epidemiolo-
gist assigned to malaria surveillance should be to assist the state
epidemiologist in promoting better morbidity reporting of ma-
laria.
A secondary responsibility of the epidemiologist, after all
responsibilities on malaria appraisal and surveillance are ful-
filled, should be to participate in finding, investigating, and
appraising typhus fever cases. He should encourage physicians
to obtain confirmation of their diagnoses by means of rickettsial
complement fixation.
A tertiary responsibility of the epidemiologist should be to
obtain epidemiologic information concerning other communi-
cable diseases.
RESPONSIBILITIES OF THE ENTOMOLOGIST: In the vicinity of
positive or presumptive malaria cases, the entomologist should
determine prevalence, abundance, and local distribution of ma-
laria vectors. After control operations are undertaken, the
entomologist should determine their effectiveness.
The secondary responsibility of the entomologist is to par-
ticipate with the engineer and state epidemiologist in the plan-
ning and operation of typhus control and evaluation activities.
The tertiary responsibility of the entomologist is to search
for vector species where insect-borne diseases are reported, and
to participate in the promotion and conduct of programs for
controlling insects of public health importance.
RESPONSIBILITIES OF THE ENGINEER: The engineer's pri-
mary responsibility will be to determine and conduct appropriate
insect control operations around positive or presumptive malaria
cases. This will include responsibility for the assignment and
management of CDC equipment and materials.
The secondary responsibility of the engineer shall be the
organization, operation and direction of typhus control pro-
134

grams within the state. The tertiary responsibility shall be
the promotion and technical supervision of locally sponsored
insect control activities.
The above outlined program should result in more accurate
reporting of malaria, assist in economically directing the final
phases of malaria eradication, and more clearly define the exist-
ing status of malaria in this nation.
A NEW CULICOIDES FROM FLORIDA
(DIPTERA, CERATOPOGONIDAE)
ELIZABETH C. BECK 1
During the course of a study of the distribution of Culicoides
in Florida, conducted from November, 1948, through September,
1950, a new species of Culicoides was found in light trap
material and is herewith described.
A.
CULICOIDES FLORIDENSIS .. .

Culicoides floridensis n. sp.
FEMALE: Uniformly light golden yellow with unspotted wings, mesono-
tum and legs unmarked. Approximately 1.1-1.2 mm. long as compared to
1.6-1.7 mm. length in C. melleus. There are two spermathecae, clear, with
a broad ring and rudimentary spermatheca. In C. melleus the spermathecae
are black and there is a conspicuous rudimentary spermatheca, but no
apparent ring.

THE FLORIDA ENTOMOLOGIST
MALE: Coloration as in female; antennal flagellum golden brownish.
Hypopygium (see fig.); apicolateral processes of the ninth tergite very
small; dorsal process of side piece long and slender, inner process boathook
shaped; aedoeagus shaped like an inverted V, similar to that of C. stellifer;
parameres are similar to those of C. haematopotus, but stouter with knob-
like projections on the base and finger-like projections near top of stem, the
tips longer and slenderer. In Root and Hoffman's (1937) key by male
hypopygium this species keys out to C. stellifer.
The following specimens are deposited in the United States National
Museum: Male holotype (U.S.N.M. No. 60924), Englewood, Sarasota County,
Florida; Female allotype, Englewood, Sarasota County, Florida. Male and
female paratypes are deposited in the Museum of Zoology, University of
Michigan.
This species most closely resembles C. melleus, except in size.
It has thus far been taken only in Sarasota County, at Englewood
on the Gulf coast, and at Myakka State Park which lies about
fifteen miles inland. It seems probable that this species is not a
salt water breeder.
The author wishes to acknowledge the aid and advice of Dr.
W. W. Wirth of the United States Museum, and Mr. R. H. Foote
of U. S. Public Health Service.

HORNED BEETLES, A STUDY OF THE FANTASTIC IN NATURE,
by Gilbert J. Arrow, edited by W. D. Hincks. iv + 154 pages, 15 plates.
1951., Dr. W. Junk, Publishers, The Hague.
For the entomologist interested in a study of some of the
most bizarre insect forms in the world, the book by the late Dr.
Arrow, who was associated with the British Museum (Natural
History) for many years, gives an excellent coverage of the
subject. The book is interestingly written, well printed, and has
a good series of photographs showing the remarkable develop-
ment of horns on the Coleoptera. Unfortunately, some of the
plates have been crowded and consequently the photographs
suffer. There are author, general, and scientific indexes. The
book should prove useful and informative to the amateur as well
as the professional entomologist.-L. B.

CONCERNING SOME AMERICAN MICROVELIA
(HEMIPTERA: VELIIDAE)
C. J. DRAKE and R. F. HUSSEY 2
This paper is based entirely upon specimens of the genus
Microvelia Westwood in the private collections of the authors.
It includes the descriptions of two new species, new synonymical
and distributional records, and discriminative notes on poly-
morphic forms of several little-known species. The types of
both new species are in the Drake collection, paratypes of M.
pexa in the collections of both authors. In the descriptions given
here, 1 millimeter equals 80 micrometer units.
Polymorphism and especially sexual dimorphism of the ap-
terous forms are very pronounced in many species of veliids.
The occurrence of marked sexual dimorphism in apterous in-
dividuals appears to be independent of polymorphism. Thus it
is necessary to characterize several types of individuals in a
single species. The striking differences in forms of the same
species, as well as widely separated and interrupted distribu-
tional records, account for part of the synonymy.
Original descriptions of a number of the species are wholly
inadequate for their identification. In addition, both the sexes
as well as both alate and wingless forms are not always repre-
sented in long series. Even in the largest collections many
species are not represented by both sexes of apterous and macrop-
terous forms. As a result several species of Microvelia de-
scribed by the earliest workers in the genus are still imperfectly
known.
Numerous species of Microvelia, such as M. summers Drake
and Harris, M. munda Drake and M. hinei Drake, rank among
the tiniest "pygmies" of the waterstriders, measuring less than
two millimeters in length. And, curiously enough, these little
dwarfs are often very widely, though sometimes spottily dis-
tributed. When fully fledged they are capable of sustained
flight. One of the most diminutive pygmies is M. hinei, which
is represented in our collections by specimens from Canada,
many states of the United States, Mexico, Insular and Central
America, and south into Brasil and Peru. In Florida this species
sometimes comes through window screens to lights. Another
widely distributed form is M. albonotata Champion, described
SIowa State College, Ames, Iowa.

from Guatemala but ranging from New York southward through
the eastern United States to the West Indies, Mexico and Central
America. It has been found in numbers in Panama (Drake)
and is plentiful in woodland habitats in Florida (Hussey).
Many species of Microvelia are shy and timid, dwelling on
the quiet waters close to shore (often among partly submerged
vegetation) in the secluded recesses and quiet coves of pools,
ponds and lakes. And, too, similar types of favorable habitats
in slow-moving waters of large and small streams are not in-
frequently inhabited by several species, notably M. americana
and some of the forms related to it.
Microvelia summers Drake and Harris
Microvelia summers Drake and Harris, 1928, Fla. Ent. 12: 8.
This very short robust species is represented by the types
from GRENADA, B. W. I., and a series of alate individuals
from PANAMA, Canal Zone, taken Feb. 10, 1939, by C. J.
Drake. Antennal formula, I:II:III:IV = 10:7:8:13. The wing-
less form is unknown. M. summers is the shortest of the group
of small robust species with short stout appendages. The other
members of this group are M. venustatis Drake and Harris, M.
lujanana Drake, and M. marginata Uhler.
Microvelia venustatis Drake and Harris
Microvelia venustatis Drake and Harris, 1933, Proc. Biol. Soc.

This species, described from "Brazil", is now known to
range widely over tropical South America. The notes which
follow are based on specimens from: BRASIL, Rio de Janeiro,
Nov. 6, 1938 (C. J. Drake) ; PARAGUAY, Colonia Independencia,
near Villarrica, Nov. 13, 1931 (R. F. Hussey) ; and east-central
PERU, Tingo Maria, Sept. 9, 1944 (E. J. Hambleton). At
Colonia Independencia both alate and apterous individuals were
found in large numbers on a quiet pool in a grass-bordered
brook. The apterous form has not been characterized before,
nor have the male genital characters been described.
APTEROUS FORM: Male, length 1.31 mm., humeral width 0.65 mm.
Female, length 1.38 mm., humeral width 0.80 mm., width at 4th abdominal
segment 0.82 mm. Very dark plumbeous, almost black, the dorsum with
fine prostrate pilosity which is more evident on the first two connexival
segments and toward the sides of the first two abdominal tergites; pronotum
138
VOL. XXXIV, No. 4 DECEMBER, 1951
with a transverse flavo-testaceous band anteriorly, this band somewhat
emarginate behind at the middle; sides of the thorax and entire venter
with sparse prostrate silvery pubescence; first antennal segment, second
rostral segment, trochanters, femora (except the tips), and tibiae beneath,
flavous; last three antennal segments, base and apex of the rostrum, tips
of the femora, tibiae above, and tarsi, fusco-testaceous; last two connexival
segments above and below commonly (though not always in the males)
with the outer half flavous, the extreme edge very narrowly brown.
Pronotum not divided into two lobes by a transverse suture, the pos-
terior half with fine punctures in two irregular transverse rows (not visible
in some males); hind margin of pronotum varying from nearly straight to
distinctly emarginate at the middle; disk with a most obsolete longitudinal
median ridge anteriorly; antero-lateral portion with ( 9 ) or without ( )
some erect hairs. Mesonotum visible only as a narrow transverse strip
behind the pronotum, entirely concealed beneath it at the sides, its hind
margin widely transversely excavated, its median length 5/16 ( 9 ) to 4/18
( ) that of the pronotum; a deep arcuate phragmal impression each side
just behind the humerall angle" of the pronotum. Metanotal triangles
extended forward along the postero-lateral margin of the pronotum about to
the middle of the latter, their median angles truncated, depressed, appar-
ently fused with the mesonotum. First abdominal tergite of males as
long as (18:18) the second and third tergites together, of females slightly
longer (20:18); first tergite with a deep fovea each side on the basal half,
punctiform in males, distinctly transverse in females. Sixth and seventh
tergites commonly with a narrow glabrous median line, narrower on the
sixth segment and abbreviated at both ends; seventh tergite of female as
long as (15:15) the fifth and sixth tergites together, seventh tergite of
male slightly longer (15:13). Fourth antennal segment longest, about
equal in length to the anterior interocular distance, distinctly shorter
(16:20) than the posterior interocular width as seen from above.
MALE: Genital segments withdrawn into the venter, the first one ap-
pearing as a narrow flavous ring, broadly interrupted beneath by a U-shaped
excavation which is largely concealed by the last ventral segment, the
exposed part of the margins of this excavation diverging anteriorly and
bearing a row of 8 to 10 long flavous hairs, this segment also thickly set
externally with yellow hairs, directed upward, on its dorso-lateral portion.
Second genital segment not protruding beyond the first, broadly subconical
as seen from behind, not visible from above.

Microvelia pudoris Drake and Harris, 1936, Proc. Biol. Soc.
Wash. 49: 105. (NEW SYNONYMY.)
Specimens of M. marginata Uhler from GRENADA, B. W. I.
(determined by Dr. W. E. China of the British Museum) are
identical with the type series of M. pudoris D. & H. from the
THE FLORIDA ENTOMOLOGIST
same island; the latter name is here synonymized with M. mar-
ginata, whose types were from ST. VINCENT.
In addition to the material from Grenada, numerous speci-
mens of M. marginata have been examined from: PERU, Tingo
Maria, Sept. 9, 1944 (E. J. Hambleton) ; PANAMA, Canal Zone,
Feb. 6-8, 1939 (C. J. Drake); Barro Colorado, C. Z., Feb. 10,
1939 (C. J. Drake); VENEZUELA, Barinitas, Dec. 1942 (P.
Anduzee); and TRINIDAD, B. W. I., Oct. 27-29, 1938 (C. J.
Drake). The apterous form is not represented in our collections.
Winged males and females of M. marginata agree closely in
size with M. venustatis D. & H., but are readily separable by the
pale and distinctly pitted hind margin of the pronotum; and the
under side of the first genital segment of the male is without
the oblique rows of long hairs found in M. venustatis. M. sum-
mersi D. & H. is a shorter species. The antennal formula of
M. marginata is: I:II:III:IV= 10:9:11:18.
Microvelia fasciculifera McKinstry
Microvelia fasciculifera McKinstry, 1937, J. Kans. Ent. Soc.
10(1) : 31.
Specimens of this very distinct species are at hand from:
ARIZONA, Huachuca Mts., Aug. 1934 (C. J. Drake); Santa
Rita Mts., Aug. 9, 1934 (E. D. Ball). MEXICO, Durango (H. F.
Wickham) ; Real de Arriba, Temescaltepec, May 13, 1923 (Hilton
and Usinger) ; Colonia Garcia, Chihuahua, May 13, 1923 (D. E.
Beck) ; Mexico City, D. F., July 30, 1950 (C. J. Drake).
WINGED FORM: Length 3.75 mm., width 1.60 mm., gradually narrowed
from the humeral angles backward. Blackish, with short brownish pubes-
cence; pronotum with a rectangular spot on each side (or a band interrupted
at the middle) near the anterior margin, also the posterior margin of the
hind process (except at the middle), testaceous or brownish-testaceous.
Hemelytra dark fuscous, the veins a little darker and clothed with short
brownish pubescence, the outer vein also with some brownish hairs at the base.
Pronotum moderately convex, wider across the humeral angles (124:100)
than long on the middle line; median raised line present but not prominent.
Pronotum in front and sides of head with short silvery hairs; width of
head across the eyes 0.88 mm.; head with the usual impressed median line.
Antennae long, dark fuscous, shortly darkly pilose, formula I:II:III:IV =
42:40:45:42. Legs slender, fuscous with the bases paler, clothed with
brownish hairs on dark areas and with much longer pale hairs beneath on
testaceous areas. Abdomen bluish black beneath.
MALE: Last ventral segment with a prominent cone-shaped tuft of
stiff dark hairs on the middle line slightly behind the middle. First genital
140
VOL. XXXIV, No. 4 DECEMBER, 1951 141
segment very long, its upper side slightly narrowed posteriorly, with the
hind margin deeply excavated; under side basally with the margins sharply
raised to form a deep cup-like cavity with truncate base, the rim on each
side just before the apex distinctly raised and there beset with long, erect,
dark bristly hairs immediately behind the cup-like cavity the concave
hind margin is deeply broadly excavated apically as in other members of
the M. americana group.
The dense cone-like tuft of long hairs on the last ventral seg-
ment and the singularly formed under side of the male first
genital segment are very distinctive characters for the recog-
nition of this species.
Microvelia pexa, new species
APTEROUS FORM: Moderately large, subfusiform (male) or broadly
ovate (female); blackish, with several small patches of silvery pubescence
or silvery hairs; pronotum with the transverse rufous-brown band inter-
rupted at the middle. Connexiva of the male concolorous with the tergites,
those of female with a large quadrate brownish spot in each segment.
Legs dark fuscous with the bases pale; femora and tibiae testaceous be-
neath; front femora largely brownish above. Abdomen bluish black
beneath.
SIZE: Male, length 3.00 mm., width 1.15 mm., female, length 2.75 mm.,
width 1.30 mm. Antennal formula, male, I:II:III:IV =36:35:40:41;
female, 32:30:34:35.
THORAX: Pronotum short, not produced posteriorly, slightly longer
than the posterior lobe of mesonotum, but distinctly (1/ to ) shorter than
the anterior mesonotal lobe, which is narrowed posteriorly and broadly
truncate behind; metanotal triangles narrow, transverse, their median
angles acute.
ABDOMEN: Length, male, 2.20 mm.; female, 1.62 mm. Abdomen grad-
ually narrowed behind in males, broadly ovate in females and with wider
connexiva.
MALE: Thorax and abdomen above rather densely clothed with fine
erect dark hairs which may be difficult to see unless viewed from the side;
abdomen with slightly coarser and slightly longer hairs. Legs rather densely
clothed with moderately long pale hairs which are paler on testaceous
surfaces; hairs longer on middle and hind femora, many of them nearly
or quite twice as long as the diameter of the femur; tibial hairs usually
about twice as long as the diameter of the tibia at their point of origin,
sometimes not longer than its diameter. Hind femora armed beneath on
distal half with numerous short black teeth or short blunt spines. Genital
segments large, blackish, with long hairs; first segment, seen from above,
slightly narrowed posteriorly, broadly and deeply emarginate on the hind
margin. Under side of first genital segment very broad, deeply and
roundly impressed basally with the apex rather sharply rounded and re-
flexed, there beset with a thick, transverse crescent-shaped comb of long
pale bristly hairs just in front of the roundly produced margin; basal
discal impression black at the bottom, the raised brown lateral sides and
THE FLORIDA ENTOMOLOGIST
base beset with a thin ring of long, laterally projecting pale hairs pointed
toward the center of the saucer-like depression; deeply broadly excavated
beyond the discal impression as in other species of the americana group.
Second genital segment small, unarmed.
Type (male), allotype (female) and 20 paratypes, MEXICO,
Mexico City, D. F., July 30, 1950 (C. J. Drake and F. C. Hottes).
Other paratypes, MEXICO: 8 specimens, Valles, July 30, 1950;
3 specimens, Puebla, July 29, 1950; 2 specimens, Aguascalientes,
Aug. 5, 1950; 2 specimens, Guadalajara, Aug. 4, 1950; Durango,
Aug. 6, 1950; Cuernavaca, July 30, 1950 (all collected by C. J.
Drake).
Most closely related to M. irrasa Drake and Harris,, but
smaller, with shorter hairy clothing and different antennal for-
mula. M. gerhardi Hussey has the under side of the first genital
segment (male) somewhat similar in construction, but lacks the
clothing of long hairs on legs and body. The females of both
M. pexa and M. irrasa are very broad, and distinctly broadly
ovate. The winged form of M. pexa is unknown.
Microvelia costaiana, new species
APTEROUS FORM: Moderately large, elongate, testaceous, the sutures
between tergites and connexival segments brownish black; sides of prono-
tum and head in front blackish. Legs dark fuscous-brown, the tibiae and
femora beneath, almost all of fore femora above, bases of middle and hind
femora above, coxae, trochanters, meso- and metasternum, and prosternum
pale testaceous. Abdomen beneath blackish with bluish lustre; connexiva
beneath and last two segments of venter testaceous. Length 2.00 mm.,
width 0.55 mm.
HEAD: Width across the eyes 0.55 mm. Head with two broad yellowish
brown stripes between the eyes, coalescing posteriorly; median line indis-
tinct behind. Antennae brown-fuscous, the base paler; segment I moder-
ately stout, almost entirely pale beneath, slightly curved; II much more
slender, a little thicker apically; III and IV very slender, practically equal
in thickness. Antennal formula, I:II:III:IV= 16:11:24:34. Rostrum tes-
taceous, the terminal segment blackish.
THORAX: Pronotum twice as wide (40:20) as long, covering posteriorly
about half the mesonotum, feebly convex behind; mesonotum nearly one-
half as long as the pronotum, clothed with short hairs which are pale in
testaceous areas, brownish in darkened areas; hind femora unarmed,
scarcely thicker than the other pairs, subequal to the tibiae in length. Tarsal
segments of both middle and hind legs subequal in length.
ABDOMEN: Length 1.25 mm., width 0.58 mm. Last tergite nearly twice
as long as the preceding tergite. Venter without tubercles, slightly flat-
tened; last segment much longer than the preceding, truncate behind.
Male genital segments dark fuscous, moderately hairy; first genital seg-
ment moderately wide as seen from above, truncate behind, slightly nar-

rowed apically with the sides distinctly convex; beneath with a short
smooth base, thence deeply and broadly excavated; second segment beneath
testaceous, very strongly flattened, with some short hairs but without tufts.
Type (male), BRASIL, Rio de Janeiro, Nov. 6, 1938 (C. J.
Drake).
The completely flattened under side of the second ventral
segment at once distinguishes this species from its allies. The
venter, genital segments and hind femora are without tubercules
or spines. The female and the alate forms are unknown. M.
sarpta Drake and Harris, from Brasil, has quite differently
formed genital segments, and its middle femora are greatly en-
larged and strongly compressed and are much stouter than the
other femora. In M. costaiana the middle femora are not at
all stouter than the others. This species is named in honor of
the noted Brasilian entomologist Dr. A. M. da Costa Lima.

The winged form of this species is characterized here from
a female taken on a spring-fed pool at Colonia Troche, PARA-
GUAY, Nov. 17, 1931 (R. F. Hussey). Colonia Troche is about
35 km. northeast of Villarrica on the road to Caaguaz6. Ap-
terous individuals were found Nov. 18, swarming on temporary
rain-water pools in the road through the forest between Colonia
Troche and Caaguaz6. Apterous specimens collected by E. J.
Hambleton are before us from PERU (Aguaytia, Sept. 7, 1944)
and ECUADOR (El Topo, Oct. 5, 1944), and thus M. braziliensis
has a very wide range in tropical South America.
ALATE FEMALE: Length 3.55 mm., humeral width 1.31 mm., width of
head across the eyes 0.78 mm. Dark fuscous; head dull flavo-testaceous, a
narrow median line and a fovea each side near the hind angle of the eye,
black. Pronotum slightly wider than long (105:95), narrowly black-mar-
gined in front, behind this with a percurrent, uninterrupted, dull testaceous
transverse band; disk rather tumidly convex; lightly depressed within the
somewhat elevated humeral angles and along the posterior margins,
coarsely, shallowly and remotely punctate and covered with fine, prostrate,
rather scanty silvery pubescence; median carina faintly suggested on the
highest part of the disk, not visible elsewhere; a transverse row of punc-
tures at the hind margin of the transverse fascia; the elevated and thick-
ened humeral angles very faintly emarginate$ they and the narrow margins
of the posterior process obscure honey-yellow. Hemelytra obscurely tes-
taceous along the basal part of the costal margin, elsewhere dark fuscous,

the three apical cells and the median pre-apical cell faintly paler, the last-
named with a vague median ocellate dark spot; costa (especially toward the
base) and the corial veins set with silvery hairs somewhat longer than
those on the pronotum, and also with a few longer black hairs. All femora
with rather sparse long pale hairs beneath on the basal two-thirds of their
length, many or most of these hairs twice as long as the thickness of the
femur. Fourth antennal segment subequal in length (60:62) to the width
of the head including the eyes, the third segment very little shorter (58
units).

This quite striking species can be separated from its con-
geners by the small tubercle on the penultimate ventral segment
of the male. In addition, the second genital segment has on each
side, near the hind margin, a long, straight, sharp, horizontal
spine projecting laterally; each of these spines is about as long
as the width of the segment itself. The first genital segment is
very broad and is widened apically to permit the spine-bearing
segment to be exserted or retracted, and its broad posterior
margin is very deeply emarginate. Since the antennal formula
is the same in both sexes, the females too are readily separable
from closely allied species.
M. mimula is quite similar to M. albonotata Champion in form
and size, and both have the conspicuously silvery white spots on
the hemelytra. Their antennal formulas are different. M.
mimula has a small tubercle on the penultimate ventral segment
of the male, while M. albonotata has an extremely large testace-
ous tubercle at the base of the male venter. The spines of the
male second genital segment of M. albonotata are directed down-
ward for about half their length and then are turned obliquely
outward, and are noticeably flattened on their outer sides.
APTEROUS FORM: Male, length 1.60 mm., width 0.51 mm.; female, length
1.95 mm., width 0.56 mm. Color testaceous with some brown or blackish
markings on the pronotum; legs and antennae as in the winged form.
HEAD: Width across the eyes 0.45 mm. Broad; brownish, the median
line more or less obsolete posteriorly. Antennal formula, I:II:III:IV =
19:11:21:36.

THORAX: Pronotum covering a large part of the mesonotum, longer
than wide (male, 46:22; female, 52:21); mesonotum with lateral angles
visible; mesonotum slightly more exposed in female than in male, from 1/3
to 2/5 as long as the pronotum. Hind femora of male with a long row of
sharp spines, beneath, plus a few adventitious spines or a partial second
row.
ABDOMEN: Broader in female than in male; connexival margins almost
straight in male, but wider in female with outer margin distinctly convex.
Male venter with a small tubercle on the penultimate segment, as in winged
form.

THE FLORIDA ENTOMOLOGIST
THE AQUATIC AND SEMIAQUATIC HEMIPTERA OF
NORTHERN FLORIDA. PART 4: CLASSIFICATION
OF HABITATS AND KEYS TO THE SPECIES
JON L. HERRING
Department of Biology, University of Florida
CLASSIFICATION OF HABITATS
Sand-Bottomed Streams
Many of the small streams in northern Florida may be classi-
fied in the sand-bottomed category. The water is swift and
usually quite dark due to seepage and drainage from flatwoods
and swamps. There is practically no vegetation associated with
the stream proper.
Twenty-four species of aquatic and semi-aquatic Hemiptera
have been taken in this type of stream. The most typical are
the gerrids and the rhagovelias. Gerris nebularis as well as
one species of Rhagovelia are found only in swift-flowing sand-
bottomed streams and those of a calcareous nature. Microvelia
alachuana is confined to the sand-bottomed streams. Most of
the aquatics have been taken only in areas where an accumula-
tion of hyacinths have formed or in the small pools where the
water is rather still and leaf debris has collected. Species
present in sand-bottomed streams are:
*Gerris nebularis Mesovelia mulsanti
G. canaliculatus Pelocoris femoratus
*Metrobates anomalus comatipes Ranatra australis
Limnogonus hesione *R. nigra
*Rheumatobates rileyi *R. buenoi
*R. tenuipes Belostoma lutarium
*Rhagovelia choreutes B. testaceum
Microvelia borealis Lethocerus uhleri
*M. alachuana Trichocorixa louisianae
*Velia brachialis T. verticalis verticalis
Hydrometra myrae T. naias
H. australis Sigara zimmermdni
Calcareous Springs and Streams
Calcareous springs and streams, which form one of the most
interesting ecological habitats, occur in many areas in the high-
lands region and along the Gulf Coast. They are characterized
by clear, cold water derived from huge springs of calcareous
nature.
Characteristic forms are indicated by an asterisk.
146
VOL. XXXIV, No. 4 DECEMBER, 1951
The most striking fact about the water-bug fauna of this type
of habitat is the superabundance of the supraneuston fauna and
the almost complete absence of aquatic forms. All of the cal-
careous streams visited have been extremely rich in water strid-
ers. No other habitat offers either the abundance or variety of
forms encountered. Huge colonies of the swifter forms dart
over the surface or may be found resting in compact masses in
the shade of overhanging branches and under bridges. On only
one occasion has an aquatic species been taken. A few speci-
mens of one of the hot-bugs (Pelocoris sp.) were collected in the
roots of water hyacinths present in the stream.
Two species, Hydrometra wileyi and Trepobates pictus, have
been collected only in calcareous streams. The former is rep-
resented in my collection by numerous specimens collected at
Salt Creek and Peace River. T. pictus is known to me only
from a few specimens taken in Rainbow River in company with
Metrobates hesperius ocalensis.
The water bugs that have been collected in calcareous streams
are:
Gerris nebularis Microvelia borealis
G. canaliculatus *Rhagovelia choreutes
*Trepobates pictus Velia brachialis
Limnogonus hesione V. watsoni
*Rheumatobates rileyi Mesovelia mulsanti
*R. tenuipes Hydrometra myrae
*Metrobates hesperius depilatus H. australis
*M. h. ocalensis *H. wileyi
*M. anomalus comatipes Pelocoris sp.
Swamp-and-Bog Streams
The swamp-and-bog stream, with a pH ranging from 4.3 to
5.2, is not a common type in northern Florida. To my knowl-
edge, only one, Blue's Creek, occurs in the Gainesville region.
Its location is not well known due to its relative isolation. This
stream originates along the west side of a shallow cypress
swamp and meanders through a hydric hammock. Its banks are
rather indefinite for some distance. The water is sluggish,
strongly stained, and flows over deposits of semi-suspended silt.
The faunal list for this habitat is small but interesting. Ten
species of Hemiptera occur here, four of which are character-
istic. Microvelia buenoi and Notonecta uhleri are confined to
swamp-and-bog streams and Velia watsoni and Hydrometra
australis are found in them more frequently than elsewhere, al-
147

though both are capable of withstanding the more alkaline waters
of calcareous streams. Species present are:
Gerris canaliculatus *Hydrometra australis
*Microvelia buenoi Ranatra buenoi
M. hinei *Notonecta uhleri
*Velia watsoni Trichocorixa naias
Hydrometra myrae Sigara zimmermani
Larger Rivers
North-Central Florida is bounded by two rivers, the St. Johns
on the east and the Suwannee on the west. Both of these have
been investigated and the waterbug fauna in them has been
found to be very meager.
I have collected at only one locality on the Suwannee. This
was at the crossing of U. S. Highway 19. At this point the water
is very dark and the shore zones are completely devoid of vege-
tation. Extensive areas of yellow sand are clean-swept by the
rapid current. Chable (1947) points out the variation in vege-
tation zones in this river from its source to the mouth. No
waterbugs were collected here on any of the several trips to
this river.
The St. Johns, although differing in its arrangement of
ecological microhabitats, differs very little from the Suwannee
in its aquatic hemipteran fauna. I believe that the few species
that have been collected here are present owing to the abundance
of water hyacinths which probably brought them into the river
from the bordering swamps and small creeks. Most of the col-
lecting was done about four and one-half miles southeast of
Bostwick. During the years 1941 to 1948, a hyacinth trap was
in operation approximately thirty yards south of my collecting
point. No waterbugs, except a few corixids, were observed dur-
ing this time. In early 1948, the trap began to collapse and
large rafts of hyacinths now float along the shores. At that
time, several belostomatid nymphs, a single Ranatra australis
and numerous Mesovelia mulsanti were collected along the edge
of the river in the masses of hyacinths.
Lakes
Rogers (1933) and Chable (1947) suggest a distinction be-
tween the hammock-region and sand-shore lakes. They may be
recognized as distinct types on the basis of their geological origin.
Those of the sand regions were formed by the solution of lime-
148
VOL. XXXIV, No. 4 DECEMBER, 1951
stone at considerable depth beneath the surface of the water,
and occupy many of the deeper depressions of the rolling pine
and scrub country. They are probably the deepest of the Flor-
ida lakes and have a large expanse of open water. The lakes of
the hammock-region are usually more shallow and their surfaces
are not much lower than that of the surrounding terrain. Ac-
cording to Sellards (1914), the hammock-region lakes were
formed along the course of a former stream. From the stand-
point of aquatic Hemiptera there is very little basis for a con-
sistent division of these two types of lakes. Most of the lakes
appear to be composite in origin and they may show all degrees
of succession in some part of their basins so that there is little
consistency from one lake to another. Thus, the lakes usually
are inhabited by all of the aquatic forms of the surrounding
region. However, there is some tendency for the belostomatids
to be more abundant in the hammock-region lakes. This abund-
ance may be due to the shallowness of the water in these lakes
and the predominance of marsh vegetation. Microvelia albono-
tata is known only from a sand-shore lake, and Ranatra kirkaldyi
is also known from this type of lake, and one other locality.
List of species present in hammock-region lakes:
Limnogonus hesione Belostoma lutarium

Sinkhole Ponds
Sinkholes, many holding water, are a conspicuous element in
the Central Highlands since the area was developed upon a karst
topography of relatively slight elevation. Stubbs (1940) has
discussed the effect of solution on the geomorphology of penin-
sular Florida.
More species of waterbugs have been taken from sinkholes
than from any other type of habitat. Of the thirty-one listed
149
THE FLORIDA ENTOMOLOGIST
below, twenty-two are true aquatics. Fourteen of the forms are
characteristic of the habitat, although none of them are con-
fined to it. Many creeks enter sinkholes and may bring their
respective faunas with them into the sink.. Species present are:

Nymphaea Marshes
Nymphaea marshes, representing a stage of succession of
ponds and lakes, are common in northern Florida.
Like the other habitats that are rich in vegetation, the
Nymphaea marsh has an extensive waterbug fauna. Twenty-
four species have been collected, of which eleven are more or
less characteristic. The fauna is predominantly aquatic; only
eight of the forms are water striders. Species present are:
Gerris canaliculatus
*Limnogonus hesione
Microvelia hinei
M. borealis
Velia brachialis
*Mesovelia mulsanti

Fluctuating Ponds
In Northern Florida, numerous shallow ponds are found that
have been formed by the local solution of thinly-buried, shallow,
150
VOL. XXXIV, No. 4 DECEMBER, 1951
limestone strata. Their basins have very indefinite margins and
during the rainy seasons they may fluctuate several feet. The
permanent water is seldom more than eighteen inches deep, and
usually less. Some of these ponds disappear during the dry
seasons and are therefore not capable of supporting true hydro-
phytics. In more permanent fluctuating ponds, the water is
filled with submerged, floating and emergent vegetation.
Two rather definite types of fluctuating ponds have been in-
vestigated, the hammock-region and the flatwoods fluctuating
ponds. The first of these types is found in dense hammocks
where it is well shaded. When the shade is very heavy, the
bottom of the pond is usually covered with a thick layer of leaf
debris, and the submerged and shore vegetation are not well
developed. Receding water leaves a broad zone of bare, black
muck along the shore, often covered by layers of leaf debris.
From the standpoint of waterbugs, the hammock-region fluctuat-
ing pond is distinct from the flatwoods type. The notonectids
and corixids are more common in the former than in any other
type of pond. The list of twenty-seven species found in the
first type is almost twice as large as that of the second. Species
found in hammock-region fluctuating ponds are:
Gerris canaliculatus Belostoma lutarium
G. nebularis B. testaceum
Microvelia hinei *Notonecta indica
M. borealis *Buenoa margaritacea
Velia brachialis *B. elegans
Mesovelia mulsanti B. scimitra
M. amoena *Hesperocorixa martini
Hydrometra myrae H. nitida
H. australis *Sigara sigmoidea
Pelocoris fenoratus *S. bradleyi
Pelocoris sp. S. zimmermani
Ranatra buenoi Trichocorixa minima
R. nigra T. naias
R. drakei
The flatwoods fluctuating ponds are situated on poorly
drained, flat terrain. Their basins are very shallow and most
of them dry up completely at least once a year. Sixteen species,
of which belostomatids are the most characteristic, have been
collected in this type of pond. Species present in flatwoods
fluctuating ponds are:
Gerris canaliculatus Mesovelia mulsanti
Limnogonus hesione *Hydrometra myrae

Cypress Swamps
Cypress swamps are a conspicuous feature of northern Flor-
ida. The cool, dark water is well shaded and numerous rotting
logs are partly submerged in the black mud of the bottom. Water-
bugs are not abundant in cypress swamps. Thirteen species
have been collected, of which only three are characteristic.
Species present are:
*Gerris canaliculatus
Limnogonus hesione
Rheumatobates tenuipes
*Mesovelia mulsanti
Hydrometra myrae
*H. australis
Pelocoris femoratus
Ranatra nigra
Belostoma lutarium

Miscellaneous Habitats
ROADSIDE DITCHES: The fauna of the roadside ditches is
not distinct from that of other smaller bodies of water. The
sometimes temporary habitats usually reflect the character of
the surrounding terrain. In flatwoods, the roadside ditches are
almost identical with the fluctuating flatwoods ponds in respect
to their fauna. However, many of the smaller water striders,
as well as Gerris canaliculatus, seems to reach their peak of
abundance in these situations. Species present are:
Gerris canaliculatus
Limnogonus hesione
Microvelia borealis
M. hinei
Velia brachialis
Mesovelia mulsanti
Abedus immaculatus
Notonecta indica
Plea striola
Trichocorixa naias
BORROW PITS: Borrow pits are artificial ponds formed by
the removal of soil, usually for use on public roads. They lend
a peculiar appearance to the landscape since they are often
square or rectangular in shape. Only four species of Hemiptera
have been taken from these pits:
Mesovelia mulsanti
Buenoa margaritacea
Sigara sigmoidea
Trichocorixa naias
152
VOL. XXXIV, No. 4 DECEMBER, 1951
MUDHOLES: This classification is included since some species
of Corixidae may be confined to this type of habitat. A single
mudhole yielded three species of corixids, two of which are
known from no other locality. For a discussion of this habitat,
see part 3 of this series (under discussion of Hesperocorixa in-
terrupta). Species present are:
Hesperocorixa nitida *Sigara hubbelli
*H. interrupt
SEWAGE DUMPS: The sewage dumps may prove to be a fer-
tile habitat in which to collect notonectids. Over four hundred
specimens of Notonecta indica and Buenoa scimitra were col-
lected in a few minutes at the Alachua Airbase sewage dump.

MINUTES OF THE THIRTY-FOURTH ANNUAL MEETING
OF THE
FLORIDA ENTOMOLOGICAL SOCIETY
The thirty-fourth annual meeting of the Florida Entomologi-
cal Society was held in Winter Haven, in the Citrus Building
during September 13th and 14th, 1951. The meeting started at
10:00 a.m., September 13th, with papers being given during
the morning and afternoon sessions. The program was divided
into four main groups as follows: Miscellaneous Insects, Vege-
table Insects, Insects Affecting Man and Animals, and Citrus
Insects. Thirty-one papers were presented before the society.
A most enjoyable hospitality hour was provided by Industry in
the Florida Room of the Citrus Building, followed by a banquet.
President W. G. Bruce was toastmaster at the banquet. One
hundred and twenty-three members and guests signed the at-
tendance register.
The business meeting was called to order by President Bruce
at 11:00 a.m., September 14th. The reading of the minutes of
the 1950 meeting was dispensed with as they had been published
in Volume 34, No. 1 of the FLORIDA ENTOMOLOGIST. Presi-
dent Bruce called for old business, and the first item was a report
from the Constitutional Committee by Dr. J. W. Wilson. The
Committee recommended a change in the election of new mem-
bers of the society. The following constitutional amendment
was presented by Dr. Wilson and seconded by Dr. W. V. King,
passed with a vote of 36 to 0.
ARTICLE III-Membership
Section 1. All persons having entomological training or a sincere
interest in entomology may become active members of the Society. Applica-
tion for membership will be endorsed by two members of the Society,
accompanied by the payment of the annual dues and submitted by the
Membership Committee to the Executive Committee for action. The Secre-
tary will notify the applicant of the action taken.
Section 2. Honorary membership may be conferred by action of the
Society on anyone who has performed long and distinguished service in the
field of entomology. Any active member may propose the name of a person
for Honorary Membership. This name should be submitted in writing to
the Membership Committee not less than thirty (30) days prior to an annual
meeting.
Section 3. Upon payment of one hundred dollars ($100.00) any active
member may become a life member and shall thenceforth be granted the
privileges of the Society, be exempt from annual dues, and supplied with
THE FLORIDA ENTOMOLOGIST without further charge.

VOL. XXXIV, No. 4 DECEMBER, 1951
Mr. Jack Russell read a report prepared by Mr. Toffaletti,
who was Chairman of the Membership Committee of the society
which was charged during the 1950 meeting to study the "ways
and means of the Society." Mr. Toffaletti's report follows:
1. Members arrear in payment of dues: that a mimeographed letter be
sent again to such members urging them to forward amount due and, if
not received in a reasonable time, that such members be dropped from the
rolls of the Society in accordance with Constitution and By-Laws.
2. That the committee chairman be mailed a current list of members.
This list will be reviewed and checked against the membership list of the
American Association of Economic Entomologists. Commercial pesticide
companies will also be contacted to attempt to ascertain if other qualified
and interested personnel in their employ may be contacted, in order to
increase membership. A mimeographed letter can be prepared to send to
these prospective new members.
3. A subscription list of educational institutions and commercial firms
who are now receiving the FLORIDA ENTOMOLOGIST be provided the chairman
of the committee. This list will be reviewed with the idea of contacting
other similar institutions in an attempt to increase circulation of the
Society's journal.
4. That all entomologists in the Southeast who are not now members of
the Society be contacted by mimeographed letter urging them to join the
Society.
5. That a table be set up (if permissable) at the February meeting in
Memphis of the Cotton States Branch of the AAEE. Members of our
committee can staff this table at certain intervals during the meeting to
attempt to increase membership.
6. Preliminary programs be mailed to all members as early as possible
before annual meeting, If this is done, attendance at meetings will be
increased. Revenue from registration fees will also be increased. More
dues can be collected. Many members wait to pay their dues at the
meeting.
The Secretary was called upon for new business. A letter
was read from Julien C. Younge, Director of Library of Florida
History requesting the Society place in this library any printed
material relating to the Society's activities. The Library of
Florida has the FLORIDA ENTOMOLOGIST through Vol. 19, Nos.
1 and 2. The Secretary recommended the Society supply
the Library of Florida History a subscription to the FLORIDA
ENTOMOLOGIST beginning with Vol. 19, No. 3, which would be
a permenant record of the Society. This motion passed.
The Secretary announced he had applications for 37 new
members and 4 student members for action of the Executive
Committee. The new members are:

VOL. XXXIV, No. 4 DECEMBER, 1951
Dr. Tissot brought up the proposal made by Mr. Oliver I.
Snapp of the Georgia Entomological Society. The proposal,
made by Mr. Snapp on September 13th, was that members of the
Georgia Society would like to work out an agreement with the
Florida Society whereby the Georgia members could publish in
the FLORIDA ENTOMOLOGIST. Mr. Snapp said maybe some-
thing in the way of a subsidy could be given the Florida Society
for the right of the Georgia members to publish their papers.
A discussion followed Dr. Tissot's remarks. Dr. Berner said
outsiders could publish in the FLORIDA ENTOMOLOGIST now
and that no change would have to be made. Mr. Thames sug-
gested the Executive Committee look into the matter and try to
work out an agreement satisfactory to both societies. Dr. Tissot
also recommended the Executive Committee investigate the
matter. Dr. Griffiths said he did not think the Society should
vote on the matter until the Executive Committee made a report
at the next meeting. Mr. Deim said we should vote today and tell
the Georgia Entomological Society they can publish. Mr. Mul-
rennan moved that the President appoint a committee of five (5)
members to study the matter and report back at the next annual
meeting, and that the Georgia Entomological Society be notified
of the action taken. Motion passed. The following committee
was appointed: A. N. Tissot, Chairman, George Merrill, Lewis
Berner, W. P. Hunter, and Lewis Maxwell.
Mr. Bruce appointed Dr. Gray Butcher of Miami to represent
the Society at the Governor's Highway Safety Conference to be
held in Miami, September 27th and 28th, 1951.
Mr. Lewis Wright commented on the fact that many of the
papers given at the annual meeting were never published in the
FLORIDA ENTOMOLOGIST. He suggested that all speakers should
send in their papers to be published. Mr. W. L. Thompson
said that many speakers failed to send in their papers to be
published and that he would be one to try and do better in the
future. Dr. Berner reported that for the first time the FLORIDA
ENTOMOLOGIST had a backlog of papers. Dr. Stoner suggested
that maybe a summary of papers could be published if the
backlog was large, so that the most recent information would be
in the FLORIDA ENTOMOLOGIST. No action was taken on the
above.
