SIX NEW APHIDS FROM FLORIDA
With Description of the Sexual Forms of Another Species*
A. N. TISSOT
Many families of insects of Florida are well known through the
collections and writings of entomologists from this and other
states. The Aphiidae, however, have been largely neglected, espe-
cially from a taxonomic standpoint, with the result that compara-
tively little is known concerning the Florida fauna of this group
of insects. In the fall of 1925 the writer began a systematic study
of the aphids of the state which has been carried on continu-
ously since that time. About one-hundred-ten species are now
known for the state and this number will doubtless be greatly
increased when some practically untouched portions of the state
have been visited by collectors. A number of these species are
apparently new to science and it seems well that they should be
described and recorded. This paper contains the descriptions
of all the known forms of six new species together with the
description of the sexual forms of another species.

Type locality: Gainesville, Florida.
Types: Holotype alate viviparous female, collected near Pond
A., from Pinus taeda, April 18, 1928, (F 354-28), and morpho-
type apterous viviparous female of the same colony deposited
in the U. S. National Museum collection. Cat. No. 44302. Para-
types in the collection of the Entomology Department, Florida
Agricultural Experiment Station and in the collection of the
author. Type material collected by the author, and selected
from a series of forty-five alate and twenty-three apterous
Notes: This species is included in an unpublished manuscript
of H. F. Wilson, which was kindly loaned to the writer by Pro-
fessor Wilson. To this insect he has given the name carolina
which name is being retained with the permission of Professor
Wilson. The species is apparently rather close to Cinara australi
(Ashmead), but differs from his description in that the rostrum
reaches only to the cornicles and the third antennal segment is
not widest at the apex. On account of these differences and due
to the very general nature of Ashmead's description it seems
best to describe this as a new species rather than to refer it to
the species australi.
In the FLORIDA ENTOMOLOGIST, Vol. V, no. 2, 1921, A. C. Mason
lists Lachnus pini as feeding on Pinus taeda and in Vol. V, no.
4, 1922 of the same journal reports upon some life history ex-
periments with this same species. Slides prepared by Mason
and labeled Lachnus pini have been examined by the author and
found to be identical with the species above described. There is
some variation in size and form of body structures in different
individuals. The minimum and maximum measurements of 15
alate females are as follows:
Length of body 2.72-3.52 mm.; width of head across the compound eyes
.653-.680 mm.; length of antennal segments, I, .095-.109 mm.; II, .109 mm.;
III, .462-.544 mm.; IV, .204-.218 mm.; V, .231-.258 mm.; VI, .163-.177 mm.;
length of hind tibia 2.00-.212 mm.; first joint of hind tarsus .095-.109 mm.,
second joint .245-.286 mm. Third antennal segment with 5 to 10 sensoria,
fourth with 1 or 2, and fifth with 1 or 2 in addition to the primary apical
one. A study of seven apterous females gave the following measurements:
length 3.0-3.5 mm.;, width of head through the eyes .694-.725 mm.; length
of antennal segments, I, .095-.122 mm., II, .095-.129 mm., III, .449-.503

Notes: The most outstanding and distinctive characteristic of
this aphid is the shape of the head which is very short and broad
with pronounced lateral projections on which are situated the
eyes. These latter organs are without ocular tubercles and pro-
jecting as they do give the aphids a very peculiar appearance
when viewed from above. There is considerable variation in
size among different individuals from the same colony.

Width of head across the compound eyes, .394 mm. Head with a few very
short, fine spines. Eyes reddish; closely appressed to the head, with defi-
nite ocular tubercles. Ocelli rather small. Antennae slightly over half as
long as body. First two segments dusky or light brown; third, fourth, fifth,
and base of the sixth segment pale or very light brown, apices dark brown;
unguis of the sixth segment with basal portion pale and apex light brown.
Third segment with four rather large circular sensoria, fourth segment
without sensoria. Antennae with a few extremely short fine hairs. Length
of segments as follows: I, .048 mm., II, .048 mm., III, .190 mm., IV, .136
mm., V, .136 mm., VI, base, .109 mm., unguis, .122 mm. Rostrum yellow-
ish, with the tip light brown.
Prothorax olive-brown, lighter than the head. Meso- and meta-thorax
dark brown with the lobes very dark brown, almost black. Prothorax
somewhat wider than the head, narrowest in front, with low, blunt, lateral
tubercles. Meso- and meta-thorax each with a conical tubercle at the
anterior lateral margin. Wing insertions yellowish. Wings hyaline. Fore
wing with radial sector present though somewhat fainter than other veins;
media twice-branched. Stigma and veins light brown, a very faint shading
at the tips of the veins. Hind wing with two cross veins present; veins
very light brown. All pairs of legs dusky or light yellowish-brown, with
the tarsi light brown. Legs with short, fine, reclining, hyaline hairs, most
numerous and longest on the tibiae.

ish-yellow. Along each side of the dorsal median line is an irregular longi-
tudinal band of brighter yellowish-green with areas of the same color
along the lateral margins. Cornicles very pale yellow, almost white; trun-
cate, slightly longer than wide, somewhat constricted above the middle.
Cauda knobbed, much wider than long; armed with several curved hyaline
hairs which are slightly longer than the cauda. Anal plate bilobed with
numerous hairs much longer and thicker than those of the cauda, situated
on large conical bases. Cauda and anal plate pale dusky.
Type locality: Gainesville, Florida.
Types: Holotype alate viviparous female collected from Quer-
cus nigra, May 12, 1928 (F 302-28), placed in the U. S. National
Museum Collection. Cat. No. 44306. Paratypes from same host
and locality in the collections of the Entomology Department,
Florida Agr. Exp. Sta., of A. A. Granovsky, and in that of the
VOL. XVI-No. 1
author. Types selected from sixty-three alate females. Type
material collected by the author.
Notes: This species appears to be rather close to Neosymy-
dobius mimicus Hottes but differs from that species in the fol-
lowing respects: the abdomen does not have the greenish-brown
bands found in mimicus; the fourth and fifth antennal segments
are subequal and the unguis of the sixth is as long as, or longer
than, the fifth, and the base of the sixth is longer than the
unguis. It also appears to be rather similar to Neosymydobius
memorialis Hottes and Frison but can be distinguished from
that species by the sensoria of the third antennal segment and
the relative length of the base and unguis of the sixth segment.
This species has four to six sensoria on the third antennal seg-
ment, whereas memorialis has eight to ten. The unguis of the
sixth antennal segment is subequal to the base in luteus; in
memorialis the unguis is much longer than the base. In some
specimens of this species the abdomen is pale yellowish with
orange markings taking the place of the brighter green mark-
ings of the specimess having the greenish-yellow abdomen. A
single apterous viviparous female was taken. This specimen
was yellowish with the tarsi and the apices of the antennal seg-
ments dusky or light brown. Measurements of five alate females
as follows: length, 1.24-1.72 mm.; width of head, .367-,435 mm.;
length of antennal segments, III, .177-.258 mm.; IV, .136-.190
mm.; V, .136-.177 mm.; VI, base, .109-.136 mm.; unguis, .122-
.136 mm.; third segment with 4-6 sensoria, fourth segment
always without sensoria.

ocular tubercles. Antennae slightly shorter than the body. First two seg-
ments dark brown; third segment with basal portion yellowish-brown,
middle yellow, and apical portion very dark brown or black; fourth seg-
ment with basal half yellowish, apical half dark brown; fifth segment with
basal half light brown and apical part dark brown; sixth segment entirely

Type locality: Gainesville, Florida.
Types: Holotype alate viviparous female collected on the
grounds of the Florida Agricultural Experiment Station April
16, 1930 (F 587-30), deposited in the U. S. National Museum
Collection. Cat. No. 44307. Paratypes from the same host and
locality, in the collections of the Ent. Dept., Florida Agr. Exp.
Sta., of A. A. Granovsky, and in that of the author. Type
selected from a series of one-hundred-three alate females. Type
material collected by the author.
Notes: On the growing tips and young leaves of the native
bamboo, Arundinaria tecta were found during the spring of
1930 rather large colonies of this green aphid. The alate vivi-
parous female is the only form that has been taken, and appar-
ently all mature females are winged.

PIN WORM ON TOMATOES
Growers of tomatoes in the Bradenton district suffered rather
severe losses during the past spring from attacks of a small
caterpillar. This caterpillar bores into the fruit under the calyx.
It does not enter the fruit far, but attacked tomatoes will invari-
ably decay before they get to market; and, because of the fact
that these caterpillars are so well hidden under the calyx, detec-
tion of infested fruit is very difficult.
The caterpillars became particularly abundant towards the
close of the season. An investigation after the season closed
revealed that practically 100', of the fruit still clinging to the
vines had been attacked.
These insects were reared by Mr. H. E. Bratley of the Depart-
ment of Entomology, and submitted to the Bureau of Ento-
mology, U.S.D.A. They were identified as Gnorimoschema lyco-
