NEW THYSANOPTERA FROM CUBA
By DUDLEY MOULTON
San Francisco, California
TEREBRANTIA, 1836
Family THRIPIDAE, Uzel
Anaphothrips alternans, Bagnall
(Euthrips alternans, Bagn.)
Taken on leaf roll of Panicum barbinode, August 24, 1926,
(Moulton No. 1845) and Panicum maximum, August 30, 1926,
by Mr. L. S. Scaramuzza (Moulton No. 1846), both at Baragua,
Cuba, and on Saccharum officinarum, September 28, 1927, by
Mr. H. P. Plank at Central Jaronu, Cuba, (Moulton No. 2604).
This is the first record of this species having been found in
North America, having been known heretofore only from Egypt.
Bregmatothrips venustus, Hood
Numerous specimens of this species were taken in the leaf
rolls of Panicum barbinode, August 24, 1926 (Moulton No. 1845)
and on Panicum maximum on August 30, 1926 (Moulton No.
1846). Both collections were made by Mr. L. C. Scaramuzza at
Baragua, Cuba.
There seems to be no record of the male which was found to
be quite as numerous in these collections as was the female. The
specimens before me are brachypterous and colored like the
brachypterous females as in the original description. This ex-
tends the habitat of the species to Cuba.
Thrips panicus, Moulton, n. sp.
Female holotype. Color of head and thorax brown with much
reddish orange hypodermal pigment. Abdomen yellow at base,
shading to yellowish gray in segments three to seven, two distal
segments blackish brown. Antennal segments one, two and five

to seven dark brown with five lighter at extreme base, three
yellow, four yellow, shading to light grayish brown. Legs yel-
low. Wings brownish gray in second and third quarters. All
prominent body spines clear yellow.
Total body length 1 mm.; head, length .126 mm., width .126
mm.; prothorax, length .12 mm., width .135 mm.; pterothorax,
width .165 mm.; abdomen, width .165 mm. Segments of an-
tennae: length (width) I, 18 (27); II, 27 (21) ; III, 36 (20);
IV, 45 (18) ; V, 33 (15) ; VI, 51 (16); VII, 21; total length 240
microns. Length of spines: interocellars 21 M, pair at posterior
angles of prothorax 45 A, on ninth abdominal segment 135 A, on
tenth 135 microns. Wing spines, fore vein 3-10-2, hind vein 14.
Head as wide as long, slightly projecting in front of eyes,
cheeks almost parallel. Interocellar spines placed anterior to
posterior ocelli and slightly inward, a series of four or five
smaller ones posterior to eyes. Eyes in dorsal view longer than
wide and occupying about .4 the side of the head. Intermission
approximately twice the width of a single eye. Ocelli fully de-
veloped. Antennae twice as long as head, segments four and six
distinctly longer than others with six longer than four, style
almost half as long as four.
Prothorax of about equal length and width with head. A pair
of prominent spines on each posterior angle with one smaller
spine between each pair and three others along either side of
posterior margin. Mesothorax wider than metathorax. Legs
moderately stout. Wings fully developed, with spines as follows:
costa 20, fore vein 3-10-2, hind vein 14.
Abdomen long and slender with segments three to eight of
almost even width, nine and ten greatly reduced, ten with clear-
ly defined dorsal suture over entire length.
Type Material: Female holotype and 13 female paratypes
taken on sugar cane at Molokai, T. H., January 25, 1929 by Mr.
O. H. Swezey and on Panicum maximum at Baragua, Cuba, Aug-
ust 30, 1926 by Mr. L. C. Scaramuzza. Types in author's collec-
tion, one paratype deposited with the Hawaiian Entomological
Society at Honolulu. (Moulton Nos. 1846 and 3272.)
Type Locality: Molokai, T. H.
This species is distinct from all other members of the genus
known to me because of the shape of the head, produced some-
what in front of the eyes as found in the genus Chirothrips and
by the arrangement of spines on the fore vein of fore wings,

there being three basal spines, a series of nine or ten distributed
over the center of the wing and two at the tip. The series of
distal bristles in T. minutissimus, Linn. is not broken at end as
in this species. The long sixth and slightly shorter fourth an-
tennal segments are also characteristic. A new genus might be
erected to include this species but for the present I am placing
it in the genus Thrips.
TUBULIFERA, 1836
Family PHLOEOTHRIPIDAE, Hood
Subfamily Phloeothripinae, Priesner
Tribe Hoplothripini, Priesner
Eurythrips cornutus, Moulton, n. sp.
Female holotype: Color chestnut-brown with head, prothorax
and tip of abdomen somewhat darker. Antennal segment one
and two concolorous with head, pedicel of three yellow, remain-
der of segment three and four to eight dark brown. Legs con-
colorous with body, joints lighter, all tarsi yellow. Wings uni-
formly brownish gray. All prominent spines clear yellow ex-
cept only the large curved wing retaining spines which are dark
brown.
Total body length 1.82 mm.; head, length .183 mm., width .13
mm.; prothorax, length .13 mm., width, including coxae, .25
mm.; pterothorax, width .30 mm.; abdomen, width .36 mm.;
tube, length .135 mm., width at base .075 mm. Segments of an-
tennae: length (width) I, 39 (33) ; II, 45 (30); III, 60 (30) ; IV,
60 (30) ; V, 57 (25) ; VI, 57 (24) ; VII, 42 (22) ; VIII, 30; total
length 390 microns. Length of spines: postoculars 60 M, on an-
terior angles of prothorax 60 p, mid-laterals 60 p, on posterior
angles, outer 60 ,, inner 72 A, on ninth abdominal segment 105
i, at end of tube 90 microns.
Head 1.5 times longer than width across cheeks, front of head
narrowed into a triangular process projecting in front of eyes
and bearing antennae. Cheeks strongly constricted immediately
behind eyes and with a prominent short, broad-seated horn-like
growth immediately behind the constriction, behind this the
cheeks are roughened and slightly arched. The surface within
the ocellar triangle is shaded to appear distinctly reticulate and
the entire head is stippled with white dots but without markings.
Postocular spines approximately as long as eyes, with broadly
dilated tips. Eyes moderately small, with large facets, outer sur-
face including only four or five facets. Ocelli placed far for-

ward, posterior ocelli clearly contiguous with anterior inner
margins of eyes, as large as facets of eyes. Mouth cone short
and broadly rounded, extending not over half way across pro-
sternum. Antenna more than twice as long as head, segments
three to six each with narrowed pedicel, seven with wider pedi-
cel, eight broadly joined to seven but distinct. The prothorax
has long and fully developed spines as follows: one at each an-
terior angle, one in the middle of each side and a pair at each
posterior angle, those along anterior and posterior margins are
vestigial. All prominent spines with dilated tips. The suture
which separates the plate at each posterior angle of the protho-
rax is incomplete, it curves backward, outward and ends abrupt-
ly in front of inner prominent angular spine. These plates are
thus coalesced with the pronotum.
Pterothorax with evenly formed sides. Legs reasonably short,
fore femora not noticeably enlarged, fore tarsi unarmed except
for the long hook-shaped claw. Wings fully developed but short,
reaching only to base of fifth abdominal segment, without double
fringe hairs.
Abdomen considerably wider than pterothorax. The posterior
pair of wing-holding spines on segments three to seven inclusive
strongly developed and dark brown in color, anterior pair weak.
Tube about .7 as long as head and twice as long as width at base.
Type Material: Female holotype, one female paratype col-
lected April 15, 1927 by Mr. L. C. Scaramuzza from an unknown
host plant. Types in author's collection. (Moulton No. 1852.)
Type Locality: Baragua, Cuba.
This species appears to be most closely related to E. macrops,
Hood, found in Florida, but separated from it as follows: post-
ocular spines about .33 as long as head, sides of head clearly
constricted behind eyes, cheeks arched, fore tarsi unarmed. Tube
.7 as long as head. Postocular spines half as long as head in the
species macrops, sides of head almost straight and parallel, fore
tarsus armed with a minute tooth and tube as long as head.
The abdomen is rather widely distended in the holotypic speci-
men while in a second paratype it is contracted and the total
body length is 1.2 mm., and in this latter specimen the wings
reach to the eighth abdominal segment.

Eurythrips various, Moulton, n. sp.
Female holotype. Color of head, thorax and last three abdom-
inal segments dark brown, segment two light yellowish brown,

three to seven gradually becoming darker. Legs dark brown with
all tarsi and tips of all tibiae yellowish, fore wings darkened at
base, only slightly grayish beyond, antenna uniformly dark
brown except pedicel of three which is yellow.
Total body length (abdomen distended) 1.66 mm.; head,
length .18 mm., width .144 mm.; prothorax, length .13 mm.,
width including coxae .25 mm.; pterothorax, width .28 mm.;
tube, length .144 mm., width at base .072 mm. Segments of an-
tennae (beyond second segment) : length (width) III, 57 (33);
IV, 54 (33) ; V, 54 (28) ; VI, 54 (27) ; VII, 45 (27) ; VIII, 36;
total length 390 microns. Length of spines: postoculars 69 p,
prothorax, at anterior angles 60 f, mid-laterals 54 1, at posterior
angles 75-75 1, on ninth abdominal segment 195 A, at end of tube
120 microns.
This species was found in the same collection with E. cor-
nutus, previously described but may be separated by the follow-
ing characters: head slightly constricted behind eyes, cheeks
arched only a little and without short, horn-like projections im-
mediately behind eyes. Facets of eyes small, not over half as
large as ocelli. Each fore tarsus armed with a short tooth.
Wings darkened at base only and clear or slightly gray colored
beyond. First two or three abdominal segments lighter than
the rest of the body. Spines on the ninth abdominal segment
and at tip of tube are much longer than in the former spe-
cies, namely 195 and 120 m. as compared with 105 and 90 m.
respectively. This species is separated from E. cinctus, Hood by
its clearly dilated-tipped spines and from harti, Hood by the
shorter postocular bristles and armed fore tarsi. In harti the
postocular bristles are pointed, .5 as long as head and fore tarsi
are unarmed. It may also be separated from E. macrops, Hood
by the darker brown color of legs, the lighter shading of wings
beyond the basal fifth and the shorter tube.
Type Material: Female holotype collected April 15, 1927
from an unknown host plant by Mr. L. C. Scaramuzza. Types
in author's collection. (Moulton No. 1852 B.)
Type Locality: Baragua, Cuba.

Eurythrips fuscipennis, Moulton, n. sp.
Female holotype. Color chestnut brown with fore legs and
tips of middle and hind tibiae and middle and hind tarsi almost
clear yellow. Antenna uniformly dark brown, except segments

one and two which are lighter and base of three which is yellow-
ish, wings uniformly grayish brown.
Total body length 1.48 mm. (abdomen distended); head,
length .166 mm., width .14 mm.; prothorax, length .12 mm.,
width including coxae .25 mm.; pterothorax, width .283 mm.;
abdomen width .30 mm.; tube, length .135 mm., width at base
.075 mm. Segments of antennae: length (width) I, 30 (33) ; II,
45 (30); III, 54 (30); IV, 48 (30); V, 51 (27); VI, 48 (28);
VII, 42 (27); VIII, 39; total length 360 microns. Length of
spines: postoculars 54 p, on anterior angles of prothorax 51 /I,
mid-laterals 60 /, on posterior angles, outer 66 I, inner 60 y, on
ninth abdominal segment 120 A, at end of tube 90 microns.
This species resembles E. cornutus, rather closely but is at
once separated by the strong, broad-seated tooth on fore tarsus,
sides of head almost straight and parallel, and the intermediate
antennal segments are shorter. It may be separated from mac-
rops, Hood by the shorter postocular bristles and the position of
the ocelli which are placed far forward and clearly separated
from the inner anterior margins of eyes, also the fore tarsal
tooth is large and distinct in this species. The tube is much
shorter than head, while in macrops, the tube is equal to the
length of the head.
Type Material: Female holotype taken April 15, 1927 from
an unknown host plant by Mr. L. C. Scaramuzza. Type in au-
thor's collection. (Moulton No. 1852 C.)
Type Locality: Baragua, Cuba.
The three new species described in this article were all col-
lected from the same host plant at the same time.
Cornutus and fuscipennis are closely related but apparently
distinct in that the former has unarmed fore tarsi and a projec-
tion behind each eye and the latter has a clearly developed tarsal
tooth. Varius has differently formed eyes, the facets are smaller
and more compact, the wings are dark only at the base and
lighter beyond, while in cornutus and fuscipennis the wings are
almost uniformly light grayish brown. Varius also has much
longer spines on the ninth abdominal segment and at tip of tube.
The postoculars and principal spines of the prothorax are long
and have clearly dilated tips in all three of these species. Fore
wings are without double fringe hairs and the posterior wing-
holding spines are strong while the anterior ones are weak.

CITRUS INSECTS OF NORTHEASTERN ARGENTINA*

I found plenty of pure old Florida red scale in that section of
the country (near Corrientes). I saw grapefruits, oranges and
lemons just covered with the Florida red scale. Saw some trees
it had almost killed. It is a little strange we don't have any Flor-
ida red scale here in the eastern half of the Province of Corri-
entes and Misiones but have the California red scale instead.
The California red scale has been brought into this section only
in the past four or five years when they first began to bring
citrus trees in here from Australia. Groves of Australian trees
are the only places we find California red scale present. I found
plenty of this scale when I first came down here on Australian
trees which had arrived in this country and had been planted
out only about ten days. Some of the trees were just covered
with adult scales showing that they had come from Australian
nurseries on the trees. I haven't seen any of the California red
scale on any of the native trees here yet which proves that it
has just been recently introduced into the country. Purple scale
and snow scale are plentiful here in the old native citrus groves.
I have also found what I suppose to be the citricola scale. It
too seems to be confined to the young groves of Australian trees.
It deposits honeydew which makes the twigs and leaves become
very black with sooty mold. It is a dirty-brownish-colored, soft-
bodied scale, somewhat flat, large and oblong. It confines itself
to the twigs and mostly the veins of the leaves. Ants and flies
are nearly always about the tree where it is present. It seems
to almost completely cover the limbs of young trees and the

trees are always very sooty-black and filthy. The growth of the
tree is also very badly retarded.
I believe I also wrote you that we have the snow scale here
and the common old purple scale which is always so plentiful
in Florida citrus groves.
The rust mite seems to be even worse here than in Florida.
Guess it is because no sulphur dusting or other means of con-
trolling them have ever been practiced here.
We are in our mid-winter down here now. Seems that it should
be Christmas instead of almost July 4th.
We had several heavy frosts here with some ice during June.
Not any damage to citrus but some young nurseries in low lands
suffered some by cold.
Such diseases as gummosis and foot rot are very bad here
among old citrus groves.
They have one disease here that I have been watching closely
and learning all I can about it. It is very fatal to citrus trees.
This disease is called "Lepra explosive." It seems to be a fun-
gus disease. I have seen plenty of it but it would be hard to de-
scribe to you in a letter. No doubt you know something of the
disease but I don't think it has ever been found anywhere in the
State of Florida.
I saw plenty of heavy sandy soil and black soil there (south-
ern border of Paraquay) similar to Florida soils. Also went into
the section where some cotton is being produced. Saw new bales
of cotton and cotton seed being loaded on river steamboats for
the Port of Buenos Aires. I examined the cotton. It was not
nearly as pretty and white as our southern U. S. A. cotton.



NOVEMBER MEETING OF THE SOCIETY

The Society met in the Agricultural Building on November
22nd, with nine members and two visitors present. Messrs. R.
D. Whitmarsh and H. A. Bess were elected to membership. The
address of the meeting, by Dr. O. C. Bryan on the classification
of Florida soils, was given upon the request of several members
interested in the ecological distribution of the plant and animal
life of the region. Dr. Bryan stressed the relation of the soils
to the biota.

Subfamily RUTELINAE
The members of this subfamily of Scarabaeidae and those
which follow comprise the division Pleurosticti of Lacordaire
and Leconte, and differ from those already treated mainly in the
position of the abdominal spiracles, the majority of which are
placed on the dorsal parts of the ventral segments and there
forming strongly diverging rows, the last spiracle being visible
behind the elytra, which do not cover the pygidium. In addition,
the Rutelinae have the ligula corneous and fused with the men-
tum to form a single plate; labrum free; antennae 9- or 10-
jointed, club 3-jointed; head and thorax unarmed in both sexes;
tarsal claws unequal, the inner one usually much more slender
than the other. In general facies they resemble closely the
Melolonthinae, and like them are phytophagous, living mainly on
the foliage of trees and shrubs. The subfamily is represented
in Florida by two tribes and eight genera.

front angles of thorax acute; body covering thin, pale; tarsal
claws entire.
*139. (13707). A. semilivida (Lec.), 1878. 403.
Length 6-6.5 mm. Oblong, parallel; head black, clypeus piceous; thorax
with a large piceous median area; elytra usually wholly pale; thorax not
twice as wide as long, narrowed in front, sides subparallel; elytra con-
jointly one third longer than wide, sides parallel; alternate intervals slight-
ly convex with scattered punctures.
Described from Tampa and Capron; "common in March and
April in the pine woods, flying shortly before sunset" (Sz.).
Gainesville on beggar weed, Aug. 13 (Doz.); Sanford (Wick.);
St. Petersburg (Fall). Ft. Myers, at light (Day.). Key West
(Schf.). Dunedin, frequent in March and April, on the foliage
of shrubs in recently burned-over ground (Bl.).
140. (13708). A. flaccida Csy., 1915, 10.
Length 6.6 mm. Differs from semilivida, according to Casey, in having
the "form more oval; clypeus wholly pale yellow; thorax twice as long as
wide, with sides more rounded; elytra conjointly not longer than wide, the
intervals all nearly flat, the second with an irregular row of punctures."
"Florida, the locality unrecorded" (Casey). Probably only a
variety of semilivida; a specimen taken with semilivida at Ft.
Myers by Davis has a yellow clypeus and shows other intermedi-
ate characters.
Genus XXXIII. ANOMALA Samouelle
A large genus of rather small dull yellow species, possessing
the characters of the subfamily and tribe, and having the ligula
large and broad, sinuate at tip; thorax with a basal marginal
line; mesosternum flat between the coxae, the metasternal su-
ture always evident; elytra not submarginate at base or deeply
striate, the striae punctate, the surface rarely with metallic
lustre; large claw of the front and middle tarsi usually cleft at
tip.
141. (13713). A. servilis Csy., 1915, 16.
Length 8 mm. Oblong-oval, stout, widest behind middle; black or pice-
ous, elytra pale near the scutellum which is broadly margined, legs reddish-
brown; thorax three-fourths wider than long, rather finely, irregularly and
sparsely punctate; elytra with intervale irregular in width, the second with
punctures broadly confused.
Described from a single male, taken at Jacksonville; no other
record.
142. (13714). A. ludoviciana Schffr.
Length 8-8.5 mm. Oblong-oval; head, thorax and scutellum dark red-












THE FLORIDA ENTOMOLOGIST


dish-brown, elytra dull yellow, the large irregular punctures darker; under
surface and legs brown, both with numerous long hairs; clypeus deeply
concave, margins broadly reflexed; elytra very irregularly and unevenly
punctate, only those punctures on sides in somewhat regular rows; tarsal
claw of front and middle tarsi feebly cleft much below the tip.
Florida, without definite station (Csy, 1915, 17). Described
from Louisiana and, as A. pubescens Blatch., from Indiana.

143. (13715). A. minute Burm.
Length 6-6.5 mm. Oval, rather robust; color very variable, sometimes
wholly black, often in great part testaceous; clypeus deeply concave; lar-
ger claw of front tarsus simple in both sexes, very small, never cleft as in
our other species.
Capron, Sanford and Enterprise (Sz.); Marion Co. (Fall).

143a. (13715a). A. minute mendica Csy., 1915, 20.
Differs from the preceding in its narrower, less convex form, and wholly
black color; punctuation everywhere stronger.
Marion Co., Florida (Csy.); Gainesville (Schf.); Brookers
(Ag. Coll.).

*144. (13730). A. undulata Melsh.
Length 8.5-9.5 mm. Dull brownish-yellow; disk of thorax piceous; elytra
usually with a curved row of piceous spots across the middle and another
at apical third, the spots often merged to form a cross-bar, sometimes re-
duced to a single spot at apical third; larger claw of front tarsi cleft
nearly to base in male, only near tip, female, its supporting joint not
toothed beneath.
Common throughout the State; recorded from eight stations
and at hand from seven others, including Ormond, Royal Palm
Park and Key West. About Dunedin it hibernates in bunches
of Spanish moss and occurs on elder in early spring. The A.
varians of the Schwarz list is a synonym.

145. (13731). A. nigropicta Csy., 1915, 33.
Length 7.8-9.5 mm. "Larger, more convex and more elongate; pale
luteo-flavate, shining; head rufous, black basally; thorax black, pale at
sides; elytra never with a small rounded subapical spot, but with two ir-
regular fasciae of detached elongate spots; thorax three-fifths to two-thirds
wider than long, surface smoother, punctures, much fewer and sparser than
in undulata; tarsal claws as in undulata." (Csy.).
"North Carolina and Kentucky to Lake Worth, Florida"
(Csy).
*145a. (13731b). A. nigropicta floridana Csy., 1915, 33.

to three transverse rows of spots on elytra, piecous, sometimes wholly
black or piceous, shining; outer or larger claw of front and middle tarsi
cleft; the claw joint toothed on under side.
Pennsylvania and Florida (Csy.). No definite station record.
146a. (13732a). A. innuba piceola Csy., 1915, 35.

148. (13737). A. exigua (Sz.), 1878, 362.
Length 4-4.5 mm. Oblong-oval, convex, shining, glabrous; head and
thorax piceous with greenish reflections; elytra dull yellow, sides fuscous,
the alternate more elevated, intervals a brighter yellow; thorax narrowed
in front, sides strongly rounded, not angulate at middle; hind tarsi much
longer than tibiae; front tibiae not dentate, the outer apical angle much
prolonged; larger claw of front and middle tarsi bifid at tip.
Types taken in May from oak shrubs on the sand hills east of
Lake Altapopka, Sumter Co. No other record. Described as a
Strigoderma.
Genus XXXIV. PACHYSTETHUS Blanchard.
Species larger and with thicker body covering than in Anom-
ala, the surface with metallic lustre; thorax without a basal mar-
ginal line; mesosternum with a polished protuberance between
the rather widely separated middle coxae, the metasternal su-
ture wanting; larger claw of front and middle tarsi cleft in both
sexes.

*149. (13739). P. marginata (Fabr.).
Length 12-15 mm. Oval, robust; head and disk of thorax green or red-
dish-brown; sides of thorax and under surface and femora dull yellow;
elytra reddish-brown; entire surface except the yellow areas with a green-
ish metallic lustre; elytral striae deep, punctate; intervals narrow, convex.
Common throughout the State; recorded from numerous sta-
tions and at hand from nine others including Ormond, and Key

West. About Dunedin it begins to appear in February on grape
and other foliage, and later on is often taken at light. The "Fla."
record of P. incolumis Csy., in the Leng Catalogue, should be
"Pa."
Genus XXXV. STRIGODERMELLA Casey.
Very small, oblong, subdepressed species, having the lateral
elytral striae irregular and confused, not deep and distinct
throughout as in the larger species of Strigoderma with which
our only species was formerly listed.
*150. (13750). S. pygmaea (Fabr.).
Length 4.6-5.2 mm. Head and thorax black, usually with a greenish
tinge; under surface and legs piceous; elytra blackish-piceous, usually
with a scutellar spot and some oblong spots on the intervals, dull yellow,
sometimes pale with only the suture and outer margins dark; front tibiae
with a short tooth and long acute spur; hind tibiae shorter than either the
femora or tarsi.
Tampa, common in April (Sz.). Gainesville, abundant on va-
rious weeds, corn and cotton, April 20-August (Doz.). Sanford
and Crescent City (Wick.); Gulfport and Miami (Fall); La
Grange and Ft. Myers (Dav.). Frequent at Dunedin in April
on the new growth in recently burned-over tracts. The S. flori-
dana Ohaus, described from Titusville, Fla. is considered by
Schaeffer (1907, 72) to be a synonym of pygmaea.

Genus XXXVI. PELIDNOTA MacLeay.
Large, convex, dull reddish-brown species having the clypeus
fused with the front, the suture absent; mandibles emarginate
or bidentate on outer side; thorax in this and the next genus
with marginal line at base. This genus and the next three com-
prise the tribe Rutelini, characterized as in the tribal key.

151. (13755). P. punctata Linn.
Length 20-25 mm. Oblong-oval; clypeus, thorax and elytra dull red-
dish-brown, glabrous; occiput, scutellum, under surface, pygidium and legs
black, strongly shining, with a darker greenish lustre; in typical punctata
(Linn.) the thorax with a small black spot at middle of each side, and usu-
ally three smaller spots on sides of each elytron; in var. notata Blanch.,
these spots absent.
Enterprise, common in May (Sz.); Biscayne Bay and Buck
Key (Sz. Ms.); Gainesville, at light in May (Doz.). Ft. Myers,
Everglade and Parish (Dav.). Though Leng retains notata
Blanch. as a var. of punctata, Casey does not mention it in his
revision of the genus (1915) and it is usually regarded as a mere
color form.









WINTER NUMBER


*152. (13757). P. lutea (Oliv.).
Length 20-22 mm. Differs from punctata in having the head, legs and
tarsi wholly pale, under surface brown with greenish lustre very faint,
the dark spots on thorax and elytra very small (var. brevicollis Csy.) or
wanting; pygidium pale with transverse scratches more distinct than in
punctata.
Florida (Csy.) ; Jacksonville, var. brevicollis (Csy., 1915, 74).
Lake City and Centreville (Ag. Coll.). Dunedin Feb. 19-June
20; Ft. Myers, March 9 and R. P. Park, June 15, taken mostly
at light. All my specimens have the black spots of thorax and
elytra evident but very small. The majority of the State records
of punctata probably belong to lutea.
Genus XXXVII. COTALPA Burmeister.
Very similar to Pelidnota in form and size, differing mainly in
having the clypeus distinctly separated from the front, paler
color and dense pubescence of under surface.
153. (13769). C. lanigera (Linn.).
Length 20-26 mm. Broadly oval, convex, robust; head, thorax and scu-
tellum greenish or yellowish with a strong metallic sheen; elytra dull yel-
low, less shining; under surface piceous, bronzed, the sterna and sides of
abdomen densely clothed with long white hairs.
Jacksonville (C. & L.). This is the only Florida record, though
the beetle doubtless occurs over the northern fourth or more of
the State.
