NEW PHYTOSEIIDAE (ACARINA: MESOSTIGMATA)
FROM FLORIDA 1
MARTIN H. MUMA
University of Florida Citrus Experiment Station, Lake Alfred
Since the reorganization of the supraspecific classification of the Phyto-
seiidae (Muma, 1961) several new species and one new genus of the family
have been collected in Florida. These new forms are described and illus-
trated below. The types are deposited in the United States National Mu-
seum in Washington, D. C., and paratypes are in the University of Florida
Collections in Gainesville, Florida, and the author's collection.
Amblyseiulus citri new species
Figure 1, A-G.
DIAGNOSIS: This species is closely related to A. lepidus (Chant) from
which it may be distinguished by the proportionately longer S and large
round metasternal scuta.
FEMALE HOLOTYPE: Dorsal scutum 0.33 mm. long and 0.20 mm. wide.
Dorsal setae, except for D1, minute; D1 about five times length of other dor-
sals; M4 and M, small, Ms elongate and weakly plumose: L,, L4 and La
elongate; La longest and weakly plumose, L4 slightly smaller than Ls and L1
about two-thirds as long as L4; Ls, Ls, Ls, L6 and L7 small with L! slightly
longer than the others: scapular setae small with S, about as long as D1 and
S2 about as long as D.-. Sternal scutum slightly wider than long and faintly
reticulate. Ventrianal scutum pentagonal, slightly longer than wide, reticu-
late and with small widely spaced preanal pores lying between the widely
spaced posterior preanal setae. Macrosetae on leg 4 longest on tarsus and
shortest on tibia, leg 1, 2 and 3 without distinct macrosetae. Peritremes
extending anteriorly between D1. Spermathecae with cervix elongate and
narrow tapering gradually from the mesal to the knobbed ectal artium.
MALE ALLOTYPE: Dorsal scutum 0.24 mm. long and 0.13 mm. wide.
Dorsal, median and lateral setae as on holotype: scapular setae as on holo-
type except they are on dorsal scutum. Ventrianal scutum roughly tri-
angular and reticulate with pores and setae as on holotype. Spermatophore
bearer "T"-shaped with one arm much longer than other.
TYPES: Holotype, allotype and female paratypes from litter beneath
citrus trees, July 18, 1960, at Sebring by Martin H. Muma. Male paratypes
from citrus litter, January 27, 1960, at Sebring by Judith A. Murrell.
Amblyseiulus clausae new species
Figure 2, A-I.
DIAGNOSIS: This species is closely related to A. lepidus (Chant) from
which it may be distinguished by the proportionately longer L, and the
remote preanal pores on the ventrianal scutum. The paratype from Titus-
ville has an elongate vase-shaped cervix and a distinct atrium on the
spermathecae.

TYPES: Holotype from canna leaf on July 24, 1960, at Winter Haven
by Martin H. Muma. Allotype and male paratype from citrus litter, De-
cember 7, 1959, at Avon Park by Helen Louise Green and Martin H. Muma.
Five female paratypes from morning glory leaves, August 4, 1960, at Winter
Haven by Martin H. Muma.
Amblyseiulus iphiformis new species
Figure 6, A-G.
DIAGNOSIS: This species is easily identified by its heavy sclerotization,
minute dorsal, median and lateral setae, and large, nearly equal sized meta-
podal scuta.
FEMALE HOLOTYPE: Dorsal scutum 0.45 mm. long and 0.41 mm. wide,
heavily sclerotized and reticulate. Dorsal setae minute; D1 small, about
one-third as long as Li: median setae M1 and M2 minute; Ms elongate, smooth
and distinctly longer than Ls: lateral setae L, L4 and La elongate and smooth
with L& longest and Ls shortest; L2, Ls, Le and L, minute with La about
three times the length of La: (scapular setae S& and S& distinguishable
but tiny), about equal to La. Sternal scutum about one-third wider
than long and reticulate. Ventrianal scutum roughly pentagonal in shape
with rounded sides, reticulate and with the preanal pores adjacent and
located between the posterior preanal setae. Macrosetae on leg 4 short,

TYPE: Holotype from citrus litter, January 19, 1960, in Turnbull
Hammock north of Mims by Judith A. Murrell.
Amblyseius (Amblyseius) hystrix new species
Figure 7, A-H.
DIAGNOSIS: This is a typical Amblyseius but closely agrees with the
descriptions and figures of Amblyscutus grandis (Berlese) of authors ex-
cept that species reportedly lacks the minute L6, L? and S2 of this species.
Should grandis prove to be a typical Amblyseius this species may be synony-
mous.
FEMALE HOLOTYPE: Dorsal scutum 0.42 mm. long and 0.38 mm. wide
and heavily sclerotized. Dorsal setae, except for D1, minute; D1 about
two-thirds as long as Li: median setae minute, except for Ms which are
elongate and smooth: Li, L4 and Ls elongate and smooth; Li less than one-
third as long as L4; L slightly shorter than Ls which is about as long as
Ms; L2, L,, L,, Le and L, minute: scapular setae minute. Sternal scutum
nearly twice as wide as long. Ventrianal scutum pentagonal, reticulate
and with the preanal pores located medial and just posterior to the posterior
preanal setae. Macrosetae on leg 4 short, longest on tarsus and shortest
on tibia. Peritremes extending anteriorly nearly to Di, spermathecae with
a short, tubular, gradually tapered cervix and an indistinct atrium.
MALE ALLOTYPE: Dorsal scutum 0.30 mm. long and 0.23 mm. wide.
Dorsal, median, lateral and scapular setae same as on holotype, except La
and L, are slightly larger than other minute setae. Ventrianal scutum
roughly triangular, produced anteriorly, rounded on the sides, reticulate

DIAGNOSIS: This species is very closely related to A. (T.) simplicissi-
mus De Leon from which it differs in the form of spermatophore bearer;
simplicissimus has no spur on the arm of the "L" and the apex is bent
caudally at the tip.
MALE HOLOTYPE: Dorsal scutum 0.27 mm. long and 0.17 mm. wide.

as La; L2, L3 and L6 small and sub-equal with L5 slightly larger and L, dis-
tinctly smaller: scapular setae small, sub-equal and located on the dor-
sal scutum. Ventrianal scutum roughly triangular, produced anteriorly,
rounded on sides reticulate and with pores situated immediately behind
the mesally located posterior preanal setae. Macrosetae on leg 4 short,
longest on tarsus and shortest on tibia. Peritremes extending anteriorly
just to the leval of D1. Spermatophore bearer "L"-shaped with a blunt
spur on the ectal margin of the arm and a rounded tip on the arm.
TYPE: Holotype from citrus leaf, January 16, 1961, in Turnbull Ham-
mock north of Mims by Judith A. Murrell.

Paraamblyseius new genus
Figure 8, A-E.
DESCRIPTION: Six pairs of dorsal setae, three pairs of median setae,
eight pairs of lateral setae all short and simple, two pairs of scapular setae
on interscutal membrane, three pairs of sternal setae, and four pairs of
preanal setae on a massive ventrianal scutum. Fourth leg without macro-
setae.
DIAGNOSIS: This genus is easily distinguished by its small size, and
the possession of a massive pair of metapodal scuta.
TYPE SPECIES: Paraamblyseius lunatus new species.
Paraamblyseius lunatus new species
FEMALE HOLOTYPE: Dorsal scutum 0.29 mm. long and 0.29 mm. wide,
heavily sclerotized and covered with thin lunate areas that increase in
size marginally. Dorsal, median and lateral setae sub-equal in size and
gradually increasing in size from front to back except D1 and D6 in which
are one-third to one-half the length of the others. Scapular setae, Si and
S2 about equal to D1 and Do in size. Sternal scutum nearly three times as
wide as long and reticulate. Ventrianal scutum large and pentagonal in
shape with all angles obtuse, reticulate and with lunate thin areas, and

lands Hammock State Park southwest of Sebring by Martin H. Muma.
Paratype with same collection data on January 29, 1961.
Cydnodromus marinellus new species
Figure 9, A-H.
DIAGNOSIS: This species is closely related to C. marinus (Willmann)
as interpreted by Chant (1959) but differs by lacking distinct macrosetae
on leg 4 and in the more anterior position of the preanal pores on the ven-
trianal scutum. There is variation in the size and distinctness of the
pores on the dorsal scutum on different specimens that otherwise are
morphologically identical.
FEMALE HOLOTYPE: Dorsal scutum 0.33 mm. long and 0.18 mm. wide,
weakly scierotized and provided with scattered irregular ovate thin areas.
Dorsal, median and lateral setae short, slender and sub-equal in size and
gradually increasing in size from front to back except for D1 and Do which
are distinctly shorter: scapular Setae S1 and S2 slightly smaller than other
setae. Sternal scutum distinctly longer than wide. Ventrianal scutum
roughly pentagonal in shape, weakly creased and with preanal pores located
behind and nearly as widely spaced as the posterior preanal setae. Legs
without distinct macrosetae. Peritremes extending anteriorly nearly to
the level of D1. Spermathecae with cervix funnel-shaped at mesal end,
abruptly tapered to a slender tube and terminating ectally in a swollen
ovate atrium.
MALE ALLOTYPE: Dorsal scutum 0.27 mm. long and 0.17 mm. wide.
Setae as in holotype except that S, and S2 are on dorsal scutum. Structure

Muma: New Phytoseiidae from Florida 9
as in holotype except on pair of pores just posterior to L4 are greatly en-
larged and "C"-shaped. Spermatophore bearer "L"-shaped, with a sharp
process opposing the arm and with the blunt apex of the arm bent sharply
forward.
TYPES: Holotype from citrus litter, April 6, 1960, at Minneola by
Judith A. Murrell. Allotype and male and female paratypes from citrus
litter, February 13, 1961, at Lake Alfred by Mary Louise Green. Male and

Cydnodromus planatus new species
Figure 10, A-B.
FEMALE HOLOTYPE: Dorsal scutum 0.34 mm. long and 0.19 mm. wide.
Station and structure nearly identical to that of C. marinellus new species.
Distinguishable differences are the presence of a single basal macroseta
on the tarsus of leg 4 and a constriction of the cervix of the spermatheca
just mesad of the lobate atrium.
MALE ALLOTYPE: Dorsal scutum 0.27 mm. long and 0.14 mm. wide.
Station and structure nearly identical to that of C. marinellus new species.
In this species the spermatophore bearer has the arm of the "L" short and
thick and the opposing process indistinct, and the tarsus of leg 4 bears a
distinct macroseta.
TYPES: Holotype and allotype from citrus litter, December 7, 1959,
at Avon Park by Helen Louise Green and Martin H. Muma. Female para-
type from citrus litter, April 31, 1960, at Arcadia by Judith A. Murrell.

the spermathecae with a bowl-shaped cervix connected by a short tube to
the swollen atrium.
MALE HOLOTYPE: Dorsal scutum 0.28 mm. long and 0.17 mm. wide.
Station and structure as in marinellus new species except this species has
the spermatophore bearer bent apically in an obtuse angle and rounded at
the tip.
TYPES: Holotype and allotype from citrus litter, April 11, 1960, at
Sebring by Judith A. Murrell.
Phytoseius floridanus new species
Figure 13, A-C.
DIAGNOSIS: This species is easily distinguished by the large pores as-
sociated with M1.
MALE HOLOTYPE: Dorsal scutum 0.25 mm. long and 0.10 mm. wide,
weakly sclerotized and with a large pair circular pores posterior to M1.
Dorsal setae small with D6 smallest, then Da and D2, D1, D5 and D4 re-

Comstock. The American Museum of Natural History is to be congratu-
lated on the publication of this magnificent volume, carefully edited by
Dr. F. H. Rindge of that institution.
The taxonomic characteristics of the genus Anaea, family Nymphalidae,
are discussed in detail, followed by a statement on phylogenetic relations
and a key to the subgenera. The bulk of the text is devoted to species de-
scriptions. The monograph is handsomely illustrated with line drawings
of wings and distribution maps. A striking feature of the volume is to be
found in the thirty beautiful, colored plates following the text.
It is rare indeed to see a volume of this magnitude published with such
an outstanding format and on paper of such high quality. The colored
plates were reproduced by offset lithography in nine printings, from paint-
ings in watercolors by Miss Marjorie Statham and Miss Dorothy Fitchew.

In his re-evaluation of the Phytoseiidae, Muma (1961) erected a large
number of new genera. The validity of some of these genera will certainly
be questioned and some of the species shifted, but in general his arrange-
ment seems better than the arrangement of species by Chant (1959) and so
Muma's classification has been followed in the present paper. In the listing
of setae and when giving setal lengths, however, the designations suggested
by Garman (1948) for distinguishing the setae of the dorsal shield have
been used rather than Muma's modifications.
All measurements are in microns and all drawings are of females except
for the spermatophoral process. The distance apart of the drawings of the
2 metapodal shields is on the same scale as the drawings of the shields.
The drawings of the services of the spermathecae are all made to the same
scale; the services are indicated by heavy lines and the atria, or what appear
to be the atria, by stippling; the vesicles have been omitted. The termin-
ology used by Schuster (1960) for the parts of the spermatheca has been
followed. The term macroseta is used here to designate leg setae which
are coarser and generally longer than are the other setae of the segment;
the tips of the macrosetae in some species are enlarged.
Typhlodromella nodosus, n. sp.
(Figures 1-5)
Typhlodromella nodosus resembles T. vulgaris (Ehara) in having the
macrosetae of leg IV enlarged at the tips, but differs from that species in
having L10 enlarged at the tip and in other characters. The male is un-
known.
FEMALE: Dorsal shield 330 long, 175 wide, strongly imbricate, with 10
lateral, 2 median, and 6 dorsal pairs of setae of the following lengths:

M1 11, M2 22; D1 19, D2 11, D3 11, D4 15, D5 16, D6 9; L10 in most speci-
mens with tip strongly expanded, in a few nearly blunt. S1 23, S2 20,
VL1 30 long. Sternal shield indistinct, apparently with 2 pairs of setae;
genital shield 69 wide near base; ventrianal shield smooth, slightly waist-
shaped, 105 long, 72 wide near anterior end and 72 wide at about level of

Holotype: Female, Erwin, Tennessee, September 24, 1960 (D. De Leon),
on Nyssa sylvatica. Paratypes: 1 female, on Rhus sp. other data same as
for holotype; 13 females, Erwin, Tenn., October 1, 1960, on Tilia sp. Addi-
tional specimens were collected on various plants at Harrison, Arkansas,

lina, March, 1958.
The species also resembles T. caudiglans (Schuster), especially in the
shape of the cervix of the spermatheca. It differs most noticeably from
that species in having all the setae of the dorsal shield shorter, except D5
which is longer; the ventrianal shield is narrower anteriorly; the macro-
setae of leg IV are shorter (leg IV of 2 paratype specimens of caudiglans
bears 3 macrosetae with tips slightly expanded), and tarsus IV is shorter.
Galendromus ruralis, n. sp.

Galendromus ruralis resembles G. pomi (Parrott) as redescribed by
Chant (1959), but differs from that species in the shape of the ventrianal
shield and in leg IV having a macroseta.

Galendromus juniperi (De Leon)
(Figure 22)
Tpyhlodromus juniperi De Leon 1959: 127; Fig. 4.
Two species were included under the name Typhlodromus juniperi. A
study of the spermathecae of the specimens under this name showed that
the holotype is distinct from the paratype specimens, which are thus un-
named. Differences in number and size of structures which at the time
appeared to be variations within the species are specific differences; these
are for juniperi as follows: L1 20, L2 20, L4 13 long, ventrianal shield bor-
dered by 3 pairs of interscutal setae, primary metapodal shield 24 long,
tarsus IV with macroseta 14 long. Cervix of spermatheca of shape shown
in figure 22 and about 12.6 long. The male is unknown. The illustration
of the dorsal shield and of the ventrianal shield of this species applies
equally well (except for the less waist-shaped ventrianal shield of juniperi)
to the unnamed specimens which are described below.
Galendromus juniperoides, n. sp.
(Figure 23)
Galendromus juniperoides resembles G. juniper differing most notice-
ably from that species in the number of interscutal setae, in the length of

Vol. 45, No. 1
De Leon: New Phytoseiids from Southeastern States 27
specimen was collected at Columbus, Ohio, August, 1957, on Helianthus.
This species also resembles A. (T.) dillus (De Leon) in general facies,
but can be readily distinguished from that species by the longer M2 seta
and longer and narrower cervix of the spermatheca (the cervix of the
spermatheca of dillus is about 27 long and 2.1 wide at midlength). A species
that is A. dillus or very close to it is rather common in the area between
Erwin, Tenn., and Pensacola, North Carolina; the specimens in that area
differ from the type specimens from Florida and Georgia in having some-
what longer setae on the dorsal shield, but the male is unknown and until
it is collected the status of the more northern population is uncertain.
The types and paratypes of the new species described above are in the
author's collection.

The Mite* is no longer mighty
The ability of KELTHANE to
kill on initial contact the impor-
tant mites that endanger your
crops, plus its long residual
action, add up to both effective
and low cost mite control.
KELTHANE cleans up mites fast,
including species that have
developed resistance to phos-
phates. Its long and strong
residual action also means effec-
tive control of migrant mites
and late-hatching colonies.
When used as recommended it
is completely safe for new foliage
and fruit finish. KELTHANE can
be used up to seven days before
harvest. Compatible with most
pesticides, it kills mites, but
will not harm beneficial insects.
To insure thorough coverage
on hard-to-wet foliage, add
TRITON B-1956, the non-oil
spreader sticker. Ask your

THE TRUE GOMPHUS CONSANGUIS SELYS
(ODONATA: GOMPHIDAE)
MINTER J. WESTFALL, JR.' AND RICHARD P. TROGDON 2
In 1879 Edmond de Selys-Longchamps described Gomphus consanguis
from a single male specimen collected in North Carolina by M. Morrison.
James G. Needham in 1943 described a nymph collected in Cataloochie Creek,
Great Smoky Mountains National Park, North Carolina, which he supposed
to be this species. A male specimen in the American Museum of Natural
History collected by W. Beutenmueller in "Valley of Black Mountains",
North Carolina, June 25, 1906, was described in 1944 by Elsie Broughton
Klots. She figured this specimen and referred it to Gomphus consanguis,
writing that, "This specimen differs from the original description in the
absence of the small yellow spot behind the median ocellus, in the black in-
stead of the yellow occiput, in the confluence of the humeral and ante-
humeral stripes, and in the interruption of the first lateral stripe. There
are no round yellow spots on the sides of segments 4 to 7 of this specimen,
although there are narrow yellow lateral margins." She further pointed
out that it strongly resembled Gomphus rogersi, as described by Leonora
K. Gloyd in 1936, three paratypes of which were taken near Black Moun-
tain, Buncombe County, North Carolina. In this same paper Dr. Klots
reports that Mrs. Gloyd, in describing Gomphus rogersi, had considered the
possibility of its being consanguis, but after carefully comparing her speci-
mens with Selys' description, she concluded that the differences were spe-
cific. Dr. Klots thought the American Museum specimen showed a rela-
tionship with Selys' description of consanguis that was not evident in Mrs.
Gloyd's material. The color of the occiput is not a variable character, she
stated, and it was hardly likely that in one species the color would range
from the black of Gloyd's specimens to the yellow occiput of Selys' speci-
men. Dr. Klots concluded that it was quite possible that Selys' saw a
yellow median spot and thought the entire occiput yellow with the lateral
corners obscured.
Erich Schmidt, in 1937, was unable to find a specimen in the Selys
collection labeled consanguis, but sent Mrs. Gloyd some sketches of a male
specimen from North Carolina, collected by Morrison, with the label Gom-
phus melanogaster. According to an editorial note by P. P. Calvert in a
paper by C. S. Brimley (1903), Morrison's North Carolina specimens were
probably from Morganton, which is about forty miles from Black Mountain.
It was Dr. Klots' opinion that all of these specimens were consanguis with
individual variations, such as are found in other species of Gomphus. In
1953 the senior author collected six males at Highlands, North Carolina 3,
which fitted Mrs. Gloyd's description. In the light of Dr. Klots' paper dis-
cussed above, these were labeled consanguis.

In the Manual of the Dragonflies of North America, Needham and
Westfall (1955) treated rogersi as a synonym of consanguis. A male speci-
men collected by Ralph L. Chermock at Foltz Hill, Pennsylvania was de-
scribed and illustrated. This specimen was sent to Dr. Needham by Robert
S. Hodges and Septima C. Smith of Tuscaloosa, Alabama. It was returned
to Drs. Hodges and Smith and later was almost completely destroyed by
dermestids. George H. Beatty, III, and Alice Ferguson Beatty have sent
the senior author a reared female of this same species from Pennsylvania,
and they have others in their collection. They have kindly given us per-
mission to report this rearing in confirming the identity of many nymphs
the senior author collected in North Carolina.
On June 16 and June 23, 1959, the junior author collected near Blount-
ville, Tennessee, a total of nine males, one of which he sent to the senior
author for identification. It was seen at once that his specimen fitted per-
fectly Selys' description of consanguis, and was obviously different from
the North Carolina and Tennessee specimens described as rogersi by Mrs.
Gloyd, as well as all other specimens seen which had previously been re-
ferred to consanguis. He was urged to collect additional specimens, espe-
cially females and nymphs. From June 9 to June 29, 1960, he collected 19
males and one female at the same location, but he could not find the nymphs
or exuviae.
In 1961 the junior author collected six nymphs at the Sullivan County
locality where he had taken the adults. They were transported alive to
Knoxville, and subsequently to Gainesville where the senior author reared
two males and one female. These were unquestionably the true consanguis.
The characters to separate them from the nymphs of rogersi were readily
seen.
Gomphus consanguis Selys
Since the original description of the type male is in French and the
female has not been described, we here present a description of both sexes.
We base the description of the male on a specimen which we are designating
as a neotype since the type male is apparently lost or destroyed. The de-
scription parallels that of Mrs. Gloyd's 1936 description of rogersi for
comparison.
NEOTYPE MALE: Pale colors are light greenish gray unless otherwise
stated.
Head: Labium pale, apical two-thirds of median lobe and tips of lat-
eral lobes black. Labrum pale with a black apical border, narrower basal
stripe, and a median rounded spot black. Mandibles pale, mesal margins
and tips black. Genae black. Anteclypeus pale, postclypeus pale with the
fronto-clypeal suture covered laterally by a black band which almost dis-
appears in the middle and is not connected with the small isolated spots on
the fronto-nasal punctae. Frons pale, basal one-fifth of dorsal surface
black extending laterally to join the black of the fronto-clypeal suture.
Vertex black with a rounded spot behind the median ocellus. Dorsal sur-
face of the occiput pale except for narrow lateral margins of black. Rear
of head black except for the under surface of the occiput which is pale.
Thorax: Prothorax mostly black; front lobe with a broad pale anterior
margin; middle lobe with a small bilobed median and a postero-lateral spot
pale; hind lobe entirely black. Synthorax with the middorsal carina to its
Westfall: The True Gomphus consanguis Selys
angulation, and mesothoracic half-collar pale. Dorsal mesepisternal pale
stripes broad, slightly divergent, broadly confluent with the wide half-collar
below and almost reaching the antealar carina above. Pale antehumeral
about one-third as wide as the mesepisternal stripe, complete, though con-
stricted above and widest near the antealar carina. Black posthumeral
broad, about one-third the width of the mesepimeron and confluent with
the black of the mesepisternum. First lateral dark stripe complete, about
half as wide as the dark posthumeral, and confluent with it both above and
below. Second lateral dark stripe slightly wider above, connected obscurely
with the latero-ventral dark area of the metepisternum ventral to the meta-
stigma and to the dark ventral area of the metepimeron. Upper three-fifths
of the mesinfraepisternum and upper half of the metinfraepisternum black.
Antealar sinus black. Coxae pale with a basal black spot; remainder of
legs entirely black except for the ventral surface of the prothoracic femur
and trochanter which are light. First tibial keel brown, low, inconspicuous,
almost one-half of the length of tibia. Femora ventrally with numerous
prickles, some of which are larger and more or less lined up in two rows,
one on the antero-, the other on the postero-vental edge.
Abdomen: Black with following pale markings: on segment 1 a large
middorsal and a large ventro-lateral spot; on segment 2 a wide middorsal
stripe from base to apex, sharply constricted about two-thirds of the dis-
tance to apex, a small basal midlateral spot only obscurely separated from
a long median ventral area along the margin which is continuous with a
large apical spot, upper and lower surfaces of the auricles; on segment
3 a middorsal stripe almost entire length of segment, a large latero-ventral
basal spot prolonged narrowly along the entire margin; on segment 4-6 a
wedge-shaped middorsal spot about one-third length of segment, and a con-
spicuous round spot on the lateral surface at base of segment; on segment
7 a larger wedge-shaped middorsal spot about one-half length of segment,
tapered to a hair line reaching to three-fourths length of segment, a round-
ed latero-basal spot as in 4-6, and the rather broad ventral border yellow;
the expanded border of segment 8, and the border of segment 9 yellowish
half way to dorsal carina, intersegmental membranes between last three
segments yellow. Segment 10 entirely black. Urosternites pruinose black
in contrast to the shiny black of remainder of segments.
Hamules brownish black. Anterior hamule in lateral view extends
about .7 mm. beyond the ventro-lateral margin of the tergite, reaching
only about one-half the distance to the shoulder of the posterior hamule;
laminate with the mesal part directed caudad; apical margin flattened and
narrowly recurved giving a rolled appearance. Posterior hamule larger,
extending about 1.26 mm. beyond the ventro-lateral margin of the tergite;
cephalic margin with a pronounced shoulder or angulation at about three-
fourths the height of the hamule, continuing caudad for about .5 mm.
terminating in a broad recurved hook.
Abdominal appendages black. In dorsal view the inner and outer mar-
gins of each superior are subparallel almost to the apex where the outer
is rounded off to join the inner margin forming an acute sharp point.
The tips of the inferior may be seen lateral to the tips of the superiors,
being more divergent than the superior. In lateral view there is a small
anteapical ventral tooth.

Penis with the caudal margin of the first segment, known as the peduncle
or vesicle, with about a 650 sharp angle at about two-thirds the length from
the base, making a high prominent end lobe which, gives the vesicle a
greater width than length; segment 2 normal, curved; segment 3 straight,
with broad prepuce extending below segment 4 to the bases of the short
recurved filaments; segment 4 with no strong angulation on lower margin
at origin of the short filaments.
The other males are like the neotype male except for slight differences
in color pattern. In the reared and younger males the light colors tend to
be more yellow, the ventro-lateral margins of abdominal segments 8 and 9
appearing broadly yellow, but in older specimens these wide margins may
be obscurely brown with only a faint indication of yellowish in the middle.
In two specimens the antehumeral light stripe is completely separated at
the dorsal constriction, and rarely the first lateral stripe is incomplete in
the middle for a short distance, never as much as in rogersi.
FEMALE: The coloration is similar to that of the males.
Head: Labium pale, only the apical margin of the median lobe and
tips of the lateral lobes brownish.
Thorax: The hind lobe of the prothorax has a small median yellow
spot. Synthorax with mesepisternal pale stripes narrowly joined with the
antehumeral light stripes above. This is also true in the reared female but
less so. The first lateral stripe is incomplete in the middle in both females.
Abdomen: Middorsal stripes on segments 1-5 full length, only slightly
shorter on 6-7; segments 3-6 with rounded lateral spots at base, and also
with isolated lateral median stripes, the stripe on 3 only very narrowly
separated from the basal spot and the hind margin, becoming smaller on
segments 4-5, very small on 6. Ventro-lateral margins of 7-9 broadly yel-
low. Appendages black, sharply pointed, equal to segment 10 in length.
Subgenital plate (Fig. 11) extending about half the length of segment
9, the plate rather widely divided by an apical notch for about one-third
its length.
WINGS: Venation black, costa narrowly yellow on front margin in
males, obscured in some specimens; pterostigma light brown; wing tips
slightly smokey, more so in younger specimens. In the following cross vein
counts there were only two females available, one of them lacking a hind
wing. Counts are stated separately for the neotype male. Ten other males
were selected, some from each year's collecting and percentages are given.

the senior author by George H. Beatty, for inclusion in this paper. Mr.
Beatty had earlier labelled this specimen as an undescribed species. It
remains in the collection of Mr. & Mrs. Beatty.
NYMPH: Length 26.5-28.5 mm.; abdomen 16.5-17.5; hind femur 4.7-5;
width of head 5.3-5.4; width of abdomen 7.5-7.8.
General color light brown, with obscure markings of darker brown.
Surface conspicuously granulose.
Antennae, legs, and lateral margins of abdomen hairy.
Head with postero-lateral angles swollen, and hind margin only slightly
excavated. The third antennal segment is almost twice as long as the first
two segments taken together, and the fourth is only a small rounded rudi-
ment. The labium is short and stout, extending back to base of procoxae.
The prementum is parallel-sided distal to the hinge fold, the length about
equal to the width. The median lobe of the prementum equals about one-
third or slightly less of the total width, its anterior border distinctly con-
vex, with the usual brush of flat scales. In the middle there is a small
acute tooth. Palpal lobes stout, strongly incurved, forming a prominent
end hook which extends much beyond the level of the most distal of about
six conspicuous and deeply incised teeth. These teeth are obliquely trun-
cate at the tips with the sharp angles directed to rearward.
Thorax: The lateral surfaces of the prothorax are darker brown than
the dorsal surface. Synthorax with diffuse lateral brown bands. The hairy
legs have conspicuous parallel linear scars on the femora and tibiae.
Abdomen: The abdomen is depressed. There is a wide middorsal band
much darker than the areas lateral to it. There are the usual conspicuous
scars on the tergites each side of the midline. The wing cases reach the
middle of the fourth abdominal segment. The sides of the abdomen are
nearly parallel along the middle segments, becoming strongly narrowed to
rearward on segment 9. There is a middorsal groove present. There are
no dorsal hooks, though on segments 8 and 9 there are several small teeth on
the posterior margin near the midline, and on segment 9 especially, one
or two may be considerably larger than the others. The lateral spines are
well-developed on segments 7-9, but there is no trace of one on segment 6.
The lateral spines of segment 9 are about equal to the middorsal length of
segment 10, or slightly shorter. The lateral margins of segments 8 and 9
are conspicuously spinulose-serrate. The superior appendage is about one
and one-half times the middorsal length of segment 10. It is equal to the
inferiors in length, and the laterals or cerci are about four-fifths as long.

MATERIAL EXAMINED: Tennessee, Sullivan County, midway between
Tri-Cities Airport and Blountville, intersection of Adam's Chapel Road
and Tennessee Highway 37, small stream at Fowler's Fish Hatchery: 6
nymphs, April 20, 1961, from which 2 & & emerged May 2, and 1 9 May 3,
R.P.T. (U. of F.)
HABITS AND HABITAT: L. R. Fowler, who operates the fish hatchery on
the stream where all but one of the specimens were taken, stated that he
had never heard of a name for the little stream which varies from two feet
to ten feet in width, and is less than knee-deep in most places. It is spring
fed, arising about a mile from where the dragonflies were taken. The
stream is relatively short, emptying into Boone Lake approximately three
miles from the hatchery. Very little water flows during dry weather.
Mr. Fowler stated that a ten-inch pipe would carry all the water during
the driest part of the summer season. He also stated that the elevation is
about 1600 feet, and said that the underlying rock formation is slate and
limestone.
Due to the dark background along the Sullivan County stream the drag-
onflies were difficult to see while they were in flight. Fortunately they were
not unduly wary of the collector, and could be caught by a sweep of the
net from behind them. When they were at rest on vegetation along the
stream, they were easily netted. They patrolled the stream rather slowly
and hovered over the water at a height of about two or three feet. All
specimens were captured in an area approximately 150 yards below a small
rock dam on the hatchery property. None was observed farther upstream
or downstream.
Gomphus rogersi Gloyd
Mrs. Gloyd's description fits our males from Highlands, North Carolina,
very well. We give drawings for comparison with consanguis, including
a drawing of the penis which she did not describe, and the subgenital plate
which she did not see because her one female lacked abdominal segments
4-10. The ventral surfaces of the prothoracic femora and trochanters as
in consanguis are light colored, and this was not mentioned by Mrs. Gloyd,
but could easily have been overlooked on the types. Uniformly in our speci-
mens the dorsal mesepisternal light stripe is strongly constricted below
at the half-collar, and in two specimens is narrowly separated from the
half-collar by a black stripe. Also in all of our specimens the antehumeral
light stripe is always widely divided into an upper spot near the antealar
carina and a narrow lower stripe. The first lateral dark stripe is always
widely interrupted, and the second lateral stripe is slightly wider and more
distinct than in consanguis. In one male specimen there is the very slightest
indication of basal lateral spots on abdominal segments 4-7 where they are
so conspicuous in consanguis. One might easily overlook them if he were
not looking for them.
The penis (Fig. 2) has the caudal margin of the peduncle arched
slightly to an inconspicuous enlargement at the apex, so the greatest width
of the peduncle is much less than the length; segment 2 normal, curved;
segment 3 slightly curved, with a narrower, longer prepuce extending below
segment 4 than in consanguis; segment 4 with a strong angulation on lower
margin at origin of the short filaments which are still twice as long as
those of consanguis, but very short compared with such species of Gomph-

urus as fraternus. There is also a strong spine at the base of segment 4
on the upper margin.
In the single female we have at hand from Pennsylvania there is a
broad, lateral, yellow band from the base of abdominal segment 1 to the
supplementary transverse carina of segment 3, extending posteriorly to the
margin, with an indefinite dark area in the middle of the band on 2; there
is a light, lateral stripe posterior to the transverse carina of 3, but such a
spot is missing from the remaining segments, only 4 showing a faint trace
of a spot; prominent basal light spots on the sides of 4-7 as in consanguis;
ventro-lateral margins of all segments yellow, much wider on 7-9; middorsal
yellow streaks present, wider on the anterior segments, full length on 1-4,
about two-thirds length of segment on 5-7; 8-10 completely black dorsally;
appendages black, sharply pointed, equal to segment 10 in length. Sub-
genital plate (Fig. 12) extending about half the length of segment 9,
the plate narrowly divided by an apical notch for about half its length.

Pennsylvania, collected by Ralph L. Chermock June 19 and May 31, 1942,
respectively. The male was photographed for The Manual of Dragonflies
of North America, as mentioned earlier. Both specimens were almost com-
pletely destroyed and the remnants are now in the University of Florida
Collection. In the "Manual" a general female specimen, in the Smith-
Hodges Collection at the University of Alabama, was reported from Ala-
bama, collected on May 12 by E. C. Martin at Auburn, Lee County. The
specimen was softened, placed in a vial of alcohol after determination by
J. G. Needham, and was apparently returned to the Smith-Hodges Collec-
tion. The envelope with the original data label from which it was removed
is in the University of Florida Collection and was given to us by Dr. Hodges.
It has the note saying the specimen was removed to alcohol, but we have
been unable to observe the specimen again to verify the determination.
NYMPH: Dr. Needham, as mentioned earlier, described and figured the
nymph of this species by supposition under the name of consanguis in 1943.
We have been unable to find his specimen from Cataloochie Creek collected
on April 4, 1934, but the senior author has studied five nymphs collected
and labeled by Dr. Needham as "G. consanguis?". They are from Hazel
Creek, Great Smokies, North Carolina, collected the same day as the one
from Cataloochie Creek. The largest (obviously immature) is 23 mm. as
opposed to 31 mm. reported for the Cataloochie Creek specimen. Near
Highlands, North Carolina, in 1953 the senior author collected a great num-
ber of nymphs which were identified with Mrs. Gloyd's species. This in-
itial determination was prompted by the fact that the adults, with which
some of them were taken, were obviously her rogersi, which species we at
that time considered as a synonym of consanguis. Also, the fact that the
nymphs fitted exactly Dr. Needham's description of the nymph of consan-

were conspecific. This was further established upon examination of the
reared female from Pennsylvania sent to us by George H. and Alice F.
Beatty. They have generously given us permission to publish this record
and illustrate the nymph again from the exuviae.
These exuviae (31 mm. in length) have the same measurements as the
Cataloochie Creek specimen described by Dr. Needham and are undoubtedly
the same species. The exuviae are illustrated in Figs. 19-22 for ready com-
parison with the nymph of the true consanguis in Figs. 15-18. Important
differences will be emphasized in the ensuing discussion.

TAXONOMIC AFFINITIES
The adults and nymphs of consanguis and rogersi seem to show the
relationship of these species to be with the subgenus Gomphurus, though
the end segments of the abdomen of the adult males are less expanded
than in most other members of the group, and they are slightly aberrant
in some other ways. As in the other species, veins A1 and A, are separated
at their origin from the anal vein by a single cell. The gaff (common
course of Cu2 and At from the triangle to their separation) is relatively
short compared with the subgenus Hylogomphus, which almost invariably
shows two cells between the origins of A1 and A2. In Hylogomphus A,
usually runs straight or in a smooth curve to the hind margin of the wing
after leaving the end of the long gaff. In Gomphurus there is a "kink"
in this vein so that it bends sharply toward the base of the wing after leav-
ing the end of the shorter gaff and then turns toward the hind margin of
the wing. In consanguis and rogersi the penis is of the "short type", as
referred to by E. M. Walker (1957), not the "long type" of G. fraternus
(Say) which he illustrated for Gomphurus. The senior author, in describing
the new species G. septima (1956), illustrated the penes of septima, fra-
ternus, and hybridus Williamson. The first was shown to have the "short
type" of penis, and that of hybrids is intermediate in length between the
other two. In other respects these three species are all good members of
the subgenus Gomphurus. Evidently the "long type" of penis is not a
subgeneric character for this group.
In the nymphs there is the characteristic mid-dorsal groove of Gom-
phurus, as well as the coarse granulation of the surface. The lateral mar-
gins of abdominal segments 8 and 9 are strongly spinulose-serrate as in
other species of the group.
The Florida Entomologist
In the key to the adults of the subgenus Gomphurus on page 182 of the
"Manual" by Needham and Westfall (1955), rogersi should be substituted
for consanguis in the first couplet. Then consanguis will key out at couplet
10 with modestus Needham and vastus Walsh. It is very different from
these species, the end segments of the abdomen being much less expanded.
The senior author has a paper in preparation which will give further means
of differentiating both nymphs and adults of the species of the subgenus
Gomphurus in the United States.
In the nymphal key of Gomphurus on page 183 of the "Manual", con-
sanguis? falls in couplet 2 because the lateral spines of segment 9 equal the
middorsal length of segment 10, whereas in the other known species they
are one and one-half to two times the middorsal length of 10. The reared
nymphs of rogersi and consanguis will both fall in the key at this place;
however, they may be readily separated by characters shown in the draw-
ings given here. The most obvious difference is that rogersi has a well-
developed lateral spine on segment 6 which is missing in consanguis.
There are conspicuous dorsal hooks on segments 8 and 9 of rogersi, and
only the faintest suggestion of one on 9 in consanguis. The end hook of
the lateral labial or palpal lobe is much more incurved in consanguis, and
the teeth are larger and fewer.
George Beatty has sent the senior author a copy of the illustrations
mentioned earlier of G. melanogaster made for Mrs. Gloyd by Dr. Schmidt.
From these drawings it seems beyond doubt that this specimen is con-
specific with Mrs. Gloyd's species. Thus, melanogaster should be considered
as a manuscript name for G. rogersi, and an appropriate name it was, for
the abdomen appears very black in this species. The drawings portray
among other things the black occiput, the confluence of the humeral and
antehumeral dark stripes, and the interruption of the first lateral stripe.
The shape of the peduncle of the penis, the shape of the posterior hamules,
and the relative size of the anterior hamules are as in rogersi, not con-
sanguis.

STRIDULATING ORGANS IN THREE SOUTHEASTERN
IPS BARK BEETLES
R. C. WILKINSON
Agricultural Experiment Station
Gainesville, Florida
The presence of stridulating organs on the female head and prothorax
of certain Ips spp. from the western United States was reported and dis-
cussed by Wood (1961)2. Records from southern Ips spp. are lacking.
Similar organs are here reported for Ips avulsus Eichh., Ips grandicollis
Eichh., and Ips calligraphus Germ. from Alachua County in north-central
peninsular Florida.

of female (left) and male (right) Ips, calligraphus general adults. Female
head capsule shows pars strides on the midline. (x34)
Fifty males and 50 females of each species were examined after the sex
had been determined by dissection. In each of the species, a narrow, file-
like organ (pars stridens.) is located on the midline of the posterior, dorsal
surface of the female head capsule (Figure 1). The structure is trans-
versely ridged with striae spaced at approximately 0.001 mm. intervals.
The superposed complementary organ (plectrum), against which the pars
stridens rubs, is an elliptical similarly striated plate on the anterior por-

tion of the prothorax. When the head is in its normally retracted posi-
tion, the pars stridens in general females is visible through the lightly pig-
mented prothorax and offers a means for differentiating the sexes. As pig-
mentation progresses in the prothorax, the pars stridens becomes ob-
scured. Fully pigmented beetles, firmly held between the thumb and fore-
finger, move the head forward so that the presence or absence of the stridu-
lating organ can be observed through a 10x hand lens. This behavior of
the beetles allows determination of the sexes in the field.
Tests conducted with I. calligraphus show that stridulating sounds are
produced only in association with movement of the female head capsule.
Microscopic examination was made of adults held between the thumb and
forefinger in front of a high frequency microphone and sound was trans-
mitted through an amplifier to a headphone set. When a female beetle was
rotated slightly, repeated short head movements resulted in production of
a series of "squeaking" sounds ranging from 2,000 to 16,000 cycles per sec-
ond. Similar sounds were induced at will by moving the head capsule with
a dissecting pin. Males did not produce audible sound under such conditions.
INSECT INFESTATIONS OF THE HUMAN INTESTINE:
SOME UNUSUAL RECORDS
HAROLD GEORGE SCOTT
Infestation of the human intestine by the larvae of Diptera (James,
1947), Coleoptera (Palmer, 1946), and Lepidoptera (Hope, 1837) have been
reported. Diagnosis is usually made by examination of feces. Dipterous
larvae, while uncommon in fecal samples, are found regularly, but coleop-
terous and lepidopterous infestations are exceedingly rare.
Commonest larvae found in stool samples are those of flesh flies (Dip-
tera, Sarcophagidae). These probably represent contaminations of exposed
samples, since flesh flies can deposit developed larvae on samples during only
a few minutes exposure. Most other stool infestations probably involve
the presence of larvae in the intestinal tract (see James, 1947, pages 14-16).
Six unusual insect infestations of the human intestine have been diag-
nosed by the author during recent months:
BLACK CARPET BEETLE, Attagenus piceus (Olivier) (Coleoptera, Derm-
estidae), from Alabama, November, 1960 (See Hinton, 1945).
LARGER CARPET BEETLE, Trogoderma versicolor (Creutzer) (Coleoptera,
Dermestidae), from New Jersey, October, 1961 (See Hinton, 1945).
FRUIT-WORM MOTH, Carposina sp. (Lepidoptera, Carposinidae) Alabama,
October, 1961 (See Peterson, 1948).
BLUE BOTTLE FLY, Calliphora vicina Robineau-Desvoidy (Diptera, Cal-
liphoridae) New Jersey, July, 1961 (See Hall, 1948).
BRONZE BOTTLE FLY, Phaenicia cuprina (Wiedemann) (Diptera, Calliph-
oridae), New Jersey, September, 1961 (See Hall, 1948).
CHEESE SKIPPER, Piophila casei (Linnaeus) (Diptera, Piophilidae), from
New Jersey, September, 1961 (See Peterson, 1951).
As far as the author is aware, stool-sample infestation by Attagenus
piceus, Trogoderma versicolor, or Carposina spp. has not been recorded pre-
viously. Calliphora vicina and Phaenicia cuprina have been reported only
rarely from stool samples.
Piophila casei, once one of the most common flies infesting human in-
testines in the United States (Simmons, 1927) appears to have become a
rare species in stool samples due probably to improved handling of meats
and cheeses. This is the first intestinal infestation of Piophila casei that the
author has diagnosed in seven years.

MINUTES OF THE 44th ANNUAL MEETING OF
THE FLORIDA ENTOMOLOGICAL SOCIETY
The 44th annual meeting was held in conjunction with the Annual Meet-
ing of The Entomological Society of America in Miami, November 27-30,
1961. Since the 43rd meeting (1960 in Jacksonville), The Florida En-
tomological Society has become an affiliate of The Entomological Society
of America. The Florida Entomological Society did not have a separate
program in Miami; members were urged to submit papers and participate
in the E.S.A. program.
A business meeting of The Florida Entomological Society convened in
the Columbus Hotel at 5:35 P.M. on November 27th, 1961. President Lewis
Berner presided and about 30 members were present. Minutes of the 43rd
annual meeting were printed in Vol. 43, No. 4, of The Florida Entomologist.
No objections were stated so the minutes were considered as approved as
printed.
Although a second and final business session of Florida Entomological
Society was scheduled for 8:00 A.M. on November 29th, President Berner
asked that all business be transacted at the initial session. The final busi-
ness session, as scheduled, was not held.
The Treasurer-Business Manager reported on the financial status of the
Society. This report was accepted by voice vote.

cepted by voice vote.
REPORT OF AUDITING COMMITTEE
We examined the records of the Treasurer-Business Manager and found
the books in good order and the accounts in balance. We commend the
Treasurer-Business Manager for the excellent manner in which he has con-
ducted the business of the Society.

A. N. Tissot, Chairman
Chairman W. P. Hunter reported on the activities of the Interim Ad-
visory Committee on Public Relations. He commented on the difficulties
of operation of a committee of 11 members designated from various fields
of entomology in different parts of the State.
Chairman M. H. Muma of the Honors and Awards Committee reported
that this committee had decided to defer action in 1961.
Dr. R. M. Baranowski headed a committee to arrange collecting trips for
visiting entomologists to the Everglades National Park. He reported on
the success of these trips. (Since the meeting, a number of letters express-
ing appreciation for these trips have been received from entomologists who
participated in them. These letters have been placed in the Secretarial file.)
President Berner reported on his duties as Editor of The Florida En-
tomologist. A continuing publication of 48-52 pages per issue seems assured
for 1962.
The Secretary distributed copies of the proposed amendment to the
Constitution that would enlarge the Public Relations Committee to 11
members. (This proposed amendment was also mailed to members in June,
1961, by the Secretary.) J. T. Griffiths moved and D. 0. Wolfenbarger sec-
onded the adoption of this amendment. Discussion followed by Murphey,
Hunter, Hetrick, and Rogers. J. T. Griffiths withdrew his original motion
and made a new motion that the amendment be tabled. This was seconded
and passed by voice vote. The Interim Advisory Committee on Public Re-
lations will therefore be continued in 1962 with members to be appointed
by the new President.
President Berner reported that the Executive Committee had recom-
mended that surplus Society funds be placed in an insured savings account.
He also reported that the Executive Committee had chosen Gainesville for
the 1962 meeting with tentative dates of Thursday and Friday, August 30
and 31, 1962.

There were no additional nominations from the floor and these officers
were elected by voice vote. Through an error, the office of Secretary was
not designated; the current Secretary has agreed to "carry on" for another
year. The election of John O'Neill to the Executive Committee for a two-
year term replaces John King. Dr. Lewis Berner, as Immediate Past Presi-
dent, replaces Dr. A. J. Rogers on the Executive Committee.
The new president, W. C. Rhoades, was escorted to the rostrum and
installed in this office by retiring President Berner. President Rhoades
thanked the members present for their confidence in electing him and ad-
journed the meeting at 6:27 P.M.

THIS MAGNIFICENT NEW
AGRICULTURAL RESEARCH CENTER
WAS CREATED ON OUR
FAITH IN YOUR FUTURE
Working in new laboratories and greenhouses equipped with sci-
entific apparatus unknown just a few years ago, 200 American
Cyanamid Company scientists develop new chemicals to help agri-
culture produce more, better, at lower cost.
Cyanamid's new Agricultural Center in Princeton, New Jer-
sey, is a 640-acre experimental farm dedicated to finding new
products and new ideas that will solve the problems facing every-
one in the business of farming: insects, diseases and the hungers
of plants and animals. Here, new or improved chemicals for agri-
culture will go the long road from idea, through test tube, pilot
plant, on-farm test, to proven performance.
Your future is part of this new Center. For it could not have
been built without your demand for better, lower-cost chemical
tools for farming. We proudly dedicate these facilities to all the
men and women who shape the future of agriculture.

At the root of a
'100,000,000
problem...
Smaller than these dots .. the nema-
tode is destructive enough to cause
more annual damage to agriculture
than any insect known to man.
Nematodes choke off the roots of
plants so that nourishment which would
normally be gained from the soil is
severely reduced. When nematodes in-
vade a field, the plants wither, their
growth is stunted and in extreme cases
the plants die.
Shell Chemical Company, a pioneer
in the field of nematology, working
closely with federal, state and local
agricultural specialists, has developed
two outstanding soil fumigants for pro-
tecting plants from nematode damage.
They are D-D Soil Fumigant for pre-
planting application and Nemagon
Soil Fumigant, a potent soil fumigant
which can be used for treating living
plants. Both of these products have
been used by farmers all over the world
in the never-ending battle against the
nematode.
This is just another example of how
Shell Chemical Company is helping the
agricultural community grow bigger,
better yields for a growing America.
