Florida Entomologist
Official Organ of the Florida Entomological Society

VOL. XXVII NOVEMBER, 1944 No. 3

DR. E. W. BERGER

For the third time inside of a year, it becomes our painful
duty to record the death of one of the best known and best
beloved of our members. A charter member of our Society, past
secretary and past
president and asso-
ciate editor of the
Florida Entomolo-
gist Dr. E. W.
Berger. He died in
Gainesville on Au-
gust 24, after a
brief illness. Dr.
Berger was presi-
dent of our Society
in 1917; secretary-
treasurer in 1918
and secretary in
1933-34. He was
business manager of
the Florida Ento-
mologist from 1919
to 1942 and asso-
ciate editor in 1917-
1918 and again
from 1932 until the
time of his death.
Dr. Berger was
born in Berea, Ohio
on November 29, 1869. He received his A.B. from Baldwin-
Wallace College in 1891 and Ph.B. in 1894. He received his
doctor's degree from Johns Hopkins in 1899. He held the chair
of biology in Baldwin-Wallace during 1899-1901. Later he

studied at the Lakeside Laboratory of Ohio State University
at Cedar Point. In 1906, he came to the University as ento-
mologist of the Experiment Station, then located at Lake City,
a position which he held until 1911, at which time he became
state nursery inspector. In 1913, he became the Entomologist
to the newly formed State Plant Board. Failing eyesight and
a chronic disease, forced his retirement from active duty in 1943.
Dr. Berger will be best known for his research and activity
in the control of citrus insects, especially whitefly, by the use
of entomogenous fungi, particularly the red Aschersonia. He
developed the method of growing this fungus on sweet potatoes
and until 1943, supplied it to growers. Many hundreds of cul-
tures were sent out each year. For this work, and an exhibit
at the International Entomological Congress in London in 1912,
he received a silver medal. In the words of a former Chairman
of the Board of Control (Wartman) "He was the man who put
the 'fun' in 'fungus' ". At the same time, he raised and distributed
to growers, the Australian lady beetle (Vedalia) for the control
of the cottony cushion scale on citrus and other trees.
It was he who made the discovery that the whiteflies ordi-
narily attacking citrus in Florida were of two species, the
"common citrus whitefly", Dialeurodes citri (Ash.) and the
"cloudy-winged whitefly", D. citrifolii (Morgan) which he named
Aleurodes nubifera.
Dr. Berger was the first to discover the citrus canker in
Florida and was very active in the campaign which resulted
in its eradication, and he was also active in that of the Medi-
terranean fruit fly.
He was a member of the American Association for the Ad-
vancement of Science, the Entomological Society of America
and the American Association of Economic Entomologists. He
was a member of the Ohio Academy of Science and very active
in the State Horticultural Society.
Dr. Berger was the author or co-author of several bulletins
of the Florida Agricultural Experiment Station, especially on
whitefly studies; articles in the annual reports of the Experi-
ment Station, and in the Quarterly Bulletin of the State Plant
Board; and numerous papers read before the State Horticultural
Society.
He is survived by his widow, Mrs. Emily Muller Berger of
Gainesville, a daughter, Mrs. E. G. Hume, and a granddaughter,
Miss Peggy Hume, both of Florala, Alabama.-Editor.







VOL. XXVII-No. 3


In spite of his busy professional duties, Dr. Berger found
time to be intensely interested in the liberal political life of his
country.
He will be sorely missed in the meetings of our Society and
those of the State Horticultural Society, both of which meet-
ings, he seldom missed.


ADDITIONS TO THE LACHNINI OF FLORIDA
(Homoptera: Aphididae)'
A. N. TISSOT
In August 1939, the writer published some notes on the
lachnids of Florida.2 An attempt was then made to bring to-
gether all records and information pertaining to the occurrence,
distribution and host plants of these insects in Florida. Since
the publication of that paper, 78 collections of lachnids have been
recorded from the state. Two species were taken which had not
been known to occur here and two apparently undescribed species
were discovered. Some additional plants have been added to the
list of known hosts of these aphids and other new host relation-
ships have been found. Unless otherwise indicated, all collec-
tions of aphids here recorded, were made by the writer.
Essigella pini Wilson
Specimens have been collected on loblolly pine, Pinus taeda
L., Gainesville (Sugarfoot), 4/29/1940, F-1905-40; Gainesville
(Agri. Exp. Sta.), 4/10/1941, F-2149-41 and 5/4/1942, F-2352-
42; on pond pine, P. serotina Michx., Micanopy, 4/14/1941,
F-2165-41; and on slash pine, P. palustris Mill., Gainesville,
(Univ. of Fla. Campus), 12/13/1943, F-2416-43.
Eulachnus rileyi (Williams)
The discovery of this aphid at Gainesville in December, 1943,
raises some interesting and puzzling questions. Apparently,
specimens of this species had never been seen or taken in Florida
before that time. For a few weeks during the last half of
December and the first half of January, 1944, it was extremely
abundant in this vicinity. It was found on all species of pines
growing here and practically every tree examined was found

to be infested. Hundreds of alate and apterous viviparous
females and nymphs could be taken by thrusting the tips of a
few branches into an insect net and shaking them vigorously.
A very few males were taken but no oviparous females were
found. By the middle of January a decrease in their numbers
became apparent and by the end of February no more could
be found. Whence came these vast hordes and what factors
enabled them to multiply so rapidly? The following collections
were made: on slash pine, Gainesville (Univ. of Fla. Campus),
12/13/1943, F-2402-43; on loblolly pine, Gainesville (Agri.
Exp. Sta.), 1/5/1944, F-2421-44; on spruce pine, Pinus glabra
Walt., Gainesville (Agri. Exp. Sta.) 1/5/1944, F-2423-44; and
on longleaf pine, P. australis Michx. f., Gainesville (Univ. of
Fla. Campus), 1/5/1944, F-2424-44.

Cinara carolina Tissot
This still remains by far, the most prevalent and numerous
species of the group in Florida. Specimens were taken as fol-
lows: on loblolly pine, Gainesville (near Newnan Lake),
4/10/1940, F-1886-40; Gainesville (Sugarfoot), 4/29/1940,
F-1926-40; Gainesville, 4/8,/1941, F-2134-41, J. S. Haeger, coll.;

Gainesville (Univ. of Fla. Campus), 4/7/1943, F-2387-43.
Cinara juniperivora (Wilson)
Four collections of this cedar inhabiting aphid were made,
all being taken on the southern redcedar, Juniperus silicicola
(Small) Bailey: at Alachua, 3/11/1941, F-1989-41, Erdman
West, coll.; Grove Park, 3/31/1941, F-2096-41; Starke,

and E. West, colls.
Cinara longispinosa Tissot
This large lachnid with the peculiar, laterally expanded head
was taken only on the spruce pine. Collections were as follows:

Cinara osborni new species
Alate Viviparous Female Figs. 1-7
COLOR.-Living aphids were used for making the following
notes: Prevailing color brown. Head dark shining brown, eyes
and ocelli black; a narrow band of white pruinose material be-
tween the antennal bases. First two antennal segments slightly
lighter than the head, segments III to V pale yellowish-brown
with apices dark brown, VI entirely dark brown. Thorax con-
colorous with the head except for the dorsal lobes which are
dull black; the dorsal lobes and the scutellum more or less cov-
ered with pruinose material. Wings hyaline, stigma and anterior
veins black, median vein grayish, cubital and anal veins pale
at base getting gradually darker toward the apex. Femora of
all the legs very pale yellow on basal half, mid portion light

the others. Tarsi dark brown to black. Abdomen somewhat
lighter than the thorax, with small oval or circular darker brown
spots between and posterior to the cornicles. Cornicles black.
Cauda and anal plate very dark brown. The white pruinose
material forms a longitudinal row of spots on the dorsum, a
patch anterior to each cornicle, and it practically covers the
entire area between the cornicles and the cauda. It completely
covers the ventral surfaces of the head, thorax and abdomen.
HEAD AND APPENDAGES.-Width of head across the eyes,
.688 8 to .755, ave. .717. Head about twice as wide as long, with
rather prominent lateral projections supporting the eyes, the
median suture distinct. Eyes large, with large circular omma-
tidia and prominent ocular tubercles. Ocelli large, the median
one situated far down on the front of head. Head armed
with numerous long, fairly heavy, slightly curved hairs which
are situated on raised bulbous bases. Antennal segments
III to VI somewhat uneven in profile; the antennal hairs recli-
nate and generally less heavy than those on the head; the sixth

nent lateral tubercles situated far back, almost at the posterior
margin. Fore wings with subcostal vein heavy and prominent;
medial vein twice forked and very faint; stigma parallel-sided,
its outer margin extending beyond the base of the radial sector.
Legs armed with prominent hairs which are reclinate on all
the segments, those near the middle of the hind tibia about
twice as long as its diameter; length of hind tibia, 2.70 to 2.90,
ave. 2.75. Hind tibia strongly curved, tibiae of the other legs
less so. Length of hind tarsus exclusive of the claws, .311 to
.366, ave. .331.
ABDOMEN.-Dorsum of the abdomen rather thickly set with
slightly curved hairs which are generally shorter and finer than
those of the legs; some of these hairs with dark areas surround-
ing their bases. Cornicles on very steep sided conical bases
whose height is about half their greatest diameter at the base.
Height of cornicle cones, .222 to .288, ave. .264; diameter at
the base, .377 to .466, ave. .437. Cornicle bases armed with
slightly curved hairs which are about as long, but somewhat less
heavy than those at the middle of the hind tibia. Cauda and
anal plate with curved hairs, longer and heavier than those on
any other part of the body.
Apterous Viviparous Female Figs. 8-11
CoLoR.-Prevailing color brown. Head dark, shining brown;
eyes black. First antennal segment concolorous with the head,
second somewhat lighter, third segment pale with apical one-
fourth dark brown, fourth and fifth pale with about the apical
third dark brown, sixth entirely dark brown. Thorax and
abdomen brown, lighter than the head. Metathorax and all
the abdominal segments with dark irregular broken patches on
the dorsum, those on the thorax, the first abdominal segment,

and the segment between the cornicles largest and most compact.
An irregular median white line partially divides the dark patches
in the middle. Dark lateral patches on the metathorax and the
first two abdominal segments. A patch of grayish waxy ma-
terial anterior to the cornicles, and on each side of the meta-
thorax. Femora of all legs with basal portion pale and apex
dark brown. Fore and middle tibiae light brown with base
and apex dark brown; hind tibiae with a smaller light portion

as in the alate, except.that those on the antennae are somewhat
shorter in proportion to the diameter of the joints than in the
alate. Beak as in the alate, reaching well beyond the hind coxae.
THORAX, ABDOMEN AND APPENDAGES.-Legs as in the alate.
Length of hind tibia 2.64 to 2.82, ave. 2.67. Length of hind
tarsus exclusive of the claws, .311 to .355, ave. .333. Cornicle
bases with sides somewhat less steep and with the outer mar-
gin more irregular than in the alate. Height of cornicles, .266
to .311, ave. .291; width at the base, .422 to .555, ave. .482.
TYPES.-The material of this species available for study
consists of 46 microscope slides bearing 26 alate viviparous
females, 24 apterous females and 7 immature specimens. An
alate viviparous female taken on Pinus taeda L., on the Agri-
cultural Experiment Station farm, 4/10/1941, F-2152-41 and
an apterous viviparous female from the same colony, are desig-
nated as holotype and morphotype respectively. All of the
remaining specimens are designated paratypes. The collection
records of the paratypes are as follows: Gainesville, 3/22/1937,

on P. taeda, Geo. R. Swank, coll., F-1474-37 (this collection was
misidentified and listed under C. carolina in the previous paper) ;

Gainesville (Univ. of Fla. Campus), on P. palustris Mill.,
1/5/1944, F-2425-44 and 1/18/1944, F-2428-44.
The holotype and morphotype deposited in the U. S. Na-
tional Museum (Cat. No. 57186). The paratype material in
the collection of the writer and in the collection of the Ento-
mology Department, Florida Agricultural Experiment Station.
TYPE LOCALITY.-Gainesville, Florida.
TAXONOMY.-This aphid seems to be most closely related to
C. carolina Tissot but the shape of the cornicle bases and the
sensoria on the antennae serve to separate them easily. In
carolina the cornicle bases are much broader and flatter and
the sensoria are more numerous and more prominent than in
this species.
This species is named for my former teacher, Dr. Herbert
Osborn, whose help and guidance have been an inspiration to
the many students who were fortunate enough to be associated
with him.

Cinara saligna (Gmelin)
The synonymy of this large willow-feeding species with the
prominent dorsal abdominal tubercle is considerably confused.
Since having been described as Aphis saligna by Gmelin in
1788, it has gone under the generic names Lachnus, Pterochlorus
and Tuberolachnus and the specific names dentatus, punctatus,
saligna and viminalis. Various combinations of these names
occur in literature. Miller, (The American Midland Naturalist,
19: 658-672, 1938) sinks Tuberolachnus Mordvilko, the genus
under which this aphid has been most generally placed, under
Cinara, and as the validity of the specific name saligna appears
to be pretty certainly established, the name as used above seems
the best now available for the species. The Florida records are:
St. Petersburg, 2/13/1941, on Salix sp., B. C. Neeld, coll.,
F-1972-41; Bradenton, 3/24/1941, on Salix longipes Anders.,
F-2062-41; Rochelle, 4/4/1941, on S. longipes, F-2113-41; and
Gainesville (Devils Millhopper), 5/13/1941, on S. longipes,
F-2224-41.







VOL. XXVII-No. 3


Cinara wacasassae new species
Alate Viviparous Female Figs. 12-18
COLOR.-Living aphids were used for making the observa-
tions on color. This aphid is predominantly brown though the
color is partly obscured by the waxy secretion which covers
portions of the body. Head, medium brown; eyes black; ocelli
very dark brown. First antennal segment concolorous with
the head, second lighter than the first, the remaining segments
pale to slightly dusky with apices dark brown. Thorax about
same color as the head, except for the dorsal lobes which are
shining blackish-brown. Wings hyaline with venation pale.
Femora of all legs with basal two-fifths pale (practically
hyaline), apical three-fifths very dark brown. Tibiae of fore
and middle legs rather uniform blackish-brown, the hind tibiae
somewhat lighter toward the base, but with the extreme base
very dark brown. Tarsi of all the legs pale except for the
extreme apex and the claws which are dark brown. Abdomen
slightly lighter than head and thorax with a large dark brown
area around each cornicle. Cornicles black. Cauda and anal
plate concolorous with abdomen. The waxy secretion commonly
assumes the following pattern on the abdomen; three more or
less interrupted transverse bands on the dorsum near the base,
a narrow transverse stripe between the cornicles, another be-
hind the cornicles, the sides of the abdomen rather completely
covered.
HEAD AND APPENDAGES.-Width of head across the eyes,
.688 to .777, ave., .714. Head broadly rounded in front, nearly
semi-circular in outline when viewed from above. Eyes large,
globular, with circular ommatidia, ocular tubercles prominent.
Lateral ocelli situated close to the eyes. Dorsum of the head
with numerous long, fine hairs. Antennae short and rather
thick, segments III to VI faintly imbricated. The unguis of VI
arising abruptly, slender and finger-like. Sensoria large, rather
irregular in shape, and strongly tuberculate. Segment III with
5 to 8 sensoria arranged in a fairly straight row, the basal one-
third of the segment always free of them; IV with 2 or 3
sensoria; V with a secondary sensorium in addition to the
larger primary one; VI with about 6 small secondary or ac-
cessory sensoria which are widely scattered and often at some
distance from the primary sensorium. Antennal hairs long,
fine, standing at an angle of 45 to 60 degrees. Length of an-
tennal segments as follows: III, .377 to .466, ave., .421; IV,

.155 to .222, ave., .180; V, .177 to .222, ave., .199; VI, .133 to
.177 + .033 to .055, ave., .155 + .042. Total antenna, 1.13 to
1.31, ave., 1.19. Beak reaching well beyond the hind coxae,
the fifth segment long and acute.
THORAX AND APPENDAGES.-Subcosta of the fore wing
strongly developed, the other veins rather weak, the median vein
very faintly indicated, twice branched. Stigma with sides nearly
parallel, its outer apical margin extending well beyond the
base of the radial sector. Legs rather short, thickly beset with
long slender hairs which are mostly reclinate, but inclined to
be more erect on the outer side of 'the fore and hind tibiae and
the bases of the femora; the longest hairs near the middle of
the hind tibia measuring .254. Length of hind tibia, 1.55 to
2.11, ave., 1.93; length of hind tarsus exclusive of the claws,
.290 to .317, ave., .307.
ABDOMEN.-Surface of the abdomen thickly beset with long
slightly curved hairs, some of the longest on the dorsum measur-
ing .185. Cornicles situated on rather flat conical bases which
have very irregular outer margins. Hairs on cornicle cones
varying in length from .053 to .133, the longest situated on the
base of the cones and the shortest at their apex. Cauda broadly
and evenly rounded, both it and the anal plate with long, slightly
curved hairs measuring up to .215 in length.

Apterous Viviparous Female Figs. 19-21
COLOR.-Prevailing color brown; in life, a pruinose covering
gives portions of the body a silvery-grey appearance. Head very
dark brown; eyes black; first antennal segment concolorous
with the head, second lighter brown, the remaining segments
pale, with light brown apices. Beak dark brown at base and
apex with lighter middle portion. Thorax brown, somewhat
lighter than the head, dorsum with two broad diverging black
bands which extend back to the second abdominal segment and
form a very conspicuous inverted V. In cleared specimens
these diverging bands are seen as closely placed, paired, dark,
quadrangular patches on the thoracic segments and smaller
more irregular ones on the first two abdominal segments. Aside
from these bands the thorax is rather densely covered with
pruinose material. Femora with basal halves pale and apical
halves dark brown, tibiae light at base and shading darker to-
ward the apex; tarsi dark brown. Abdomen dark bronzy-brown,
with the pruinose covering less dense than on the thorax.

armed with long fine hairs which are generally more erect than
in the alate. Segment III without sensoria, IV with one to three
small sensoria, V with one or two small secondary sensoria in
addition to the larger primary one, VI with about six small
accessory sensoria which are widely scattered as in the alate.

gins as in the alate. Hairs on these bases measuring .026 to
.132, the shortest being at the apex of the cone and the longest
near the base. Cauda and anal plate as in the alate.
TYPES.-Two collections of this species have been made.
The specimens taken, consisting of seven alate viviparous
females and 42 apterous females are mounted on 25 microscope
slides. The collection records are as follows: Wacasassa River,
Levy County, Florida, 4/15/1942, on southern redcedar, Ju-
niperus silicicola (Small) Bailey, A. N. Tissot and Erdman
West, colls., F-2254-42 and Gainesville, 4/25/1942, on J. silici-
cola, A.N.T., coll., F-2342-42. An alate viviparous female and
an apterous viviparous female (F-2254-42) are designated as
holotype and morphotype respectively, the remaining specimens
being designated paratypes. The two slides bearing the holo-
type and morphotype (each bearing a paratype specimen) are
deposited in the U. S. National Museum (Cat. No. 57187). The
paratype material in the collections of the Entomology Depart-

ment, Florida Agricultural Experiment Station and of the
writer.
TYPE LOCALITY.-Wacasassa River, Levy County, Florida.
TAXONOMY.-This species appears to be closely related to
C. juniperi (DeGeer) and C. sibiricae (Gillette and Palmer)
and more extensive collecting and study may prove them to be
identical. However, certain morphological and biological fea-
tures indicate that this species is distinct from the others and
it is so considered here. In the apterous female, the cornicle
base is much broader in sibiricae than in wacasassae (.55 and
.35 respectively). The hairs on the body and appendages are
considerably longer in wacasassae than in sibiricae. Swain
(Ent. News, 32: 213, 1921) gives measurements of C. juniperi
based on specimens in the British Museum, which indicate an
appreciable difference in the relative lengths of the antennal
segments in that species and wacasassae. Average lengths are
as follows: juniperi---II, .364; IV, .168; V, .224; VI, .238;
wacasassae-III, .421; IV, .180; V, .199; VI, .197. The widely
spaced accessory sensoria on antennal segment VI appear to be
a characteristic feature of wacasassae. All specimens of this
species have been taken in colonies on fairly large branches,
beneath "ant sheds" constructed by the large brown carpenter
ant, Campanotus abdominalis floridanus (Buckley). Gillette and
Palmer state that sibiricae is solitary on the bark of twigs.

Cinara tujafilina (Del Guercio)
Only one collection of the arborvitae aphid was made during
the past five years though it could no doubt have been taken
on numerous occasions. The record is as follows: Gainesville
(Univ. of Fla. Campus) 4/7/1943, on arborvitae F-2389-43.

DREPANAPHIS TISSOTI,1 A NEW SPECIES OF APHID
FROM FLORIDA 2
CLYDE F. SMITH
This species is easily recognized by the numerous accessory
sensoria on antennal VI. Most of the known North American
species of Drepanaphis have 4 accessory sensoria around the
center primary sensorium. Drepanaphis sabrinae Miller usu-
ally has 5 or 6; D. tissoti, however has 8 to 14. The coloration
of antennals I & II of tissoti is very similar to D. nigricans
Smith but tissoti differs from nigricans in tubercles I and II
being shorter, in averaging fewer sensoria on antenal III, and
in having more accessory sensoria on VI.
COLOR: The following notes on the coloration of living ma-
terial were contributed by Dr. Tissot:
Head-black with three longtudinal milk white stripes, one
median and one on each side just inside the compound eyes,
ocelli pale, eyes reddish. First two antennal segments dusky
brown, segments III, IV and V very pale, with apices black,
extreme base of VI pale, rest of basal portion dusky, filament
dusky. o

1Named in honor of Dr. A. N. Tissot of the Florida Agricultural Ex-
periment Station, who collected this species and contributed notes con-
cerning it.

THE FLORIDA ENTOMOLOGIST


HERSE CINGULATUS Fab as an armyworm
The caterpillars of this moth are not uncommon on sweet
potato vines, but one seldom sees many in a place. They occur
scattered over the fields. However, the first week of July, 1944,
they occurred in armies in several fields near Santa Fe, in
Alachua County, Florida. They had completely stripped the
leaves from one 30-acre field and had destroyed fully half of the
leaves of another field of equal acreage. Several other fields
in the neighborhood suffered lesser damage, the caterpillars
completely stripping the plants of their leaves, including veins
and mid-rib and had fed extensively on the petioles. They
had evidently entered from adjoining fields and were making a
complete destruction of the leaves as they moved forward,
marching across the field like an army worm. Practically every
leaf was destroyed. A few feet beyond the zone of destruction,
practically none were to be observed. Behind this active front,
there would be a scattering of worms but nothing left of the
sweet potato vines except the up-standing petioles of the leaves
and the stems. There were literally hundreds of thousands of
the caterpillars in the fields. The armyworm habit was un-
doubtedly forced upon them as they consumed the potato leaves
behind them, forcing them to move to new pasture. Most of
the caterpillars were in an advanced stage of their development,
dark brown with black stripes in color, or green with heavy
black stripes bordered with yellow and the sides with prominent
V-shaped black markings. A few half grown caterpillars were
observed. The surrounding fields and woods carried a consider-
able supply of wild morning-glory vines. These were probably
the source of the infestation. Santa Fe is quite a center for
the cultivation of sweet potatoes. This insect gives promise
of being a first class pest. J. R. Watson


THE DAMAGE OF MELIPOTIS ACONTIOIDES TO THE
ROYAL POINCIANA
J. R. WATSON
The Royal Poinciana is justly famous as one of the most
beautiful shade trees in southern Florida. Until the past three
years, we had received no complaints of insect damage to these
trees, but in January 1942, as reported in the Florida Entomolo-







VOL. XXVII-No. 3


gist of December 1943, we received complaints and caterpillars
from St. Petersburg, Florida. These caterpillars, we were'able
to raise out and have identified by authorities on Lepidoptera in
the Bureau of Entomology and Plant Quarantine, U. S. D. A.
Because we could not get them
to feed on any relative of the
Poinciana which grows in the
Gainesville section, we were not
S i- able to study their life history.
During the past year, we have
had complaints of severe damage
from Ft. Myers and especially
Key West, through Mr. Stephen
C. Singleton, manager of the
Key West Chamber of Com-
c merce. He states that the de-
Sfoliation, due to the caterpillars
of this noctuid moth became
alarming in July of 1943 and many trees were defoliated during
that summer. These defoliated trees did not put out any new
growth until June of this year. A normal Poinciana tree in
that section drops its leaves in November or December and puts
them out in March or April so that the retarding of the leafing
of these trees was marked-so marked that Mr. Singleton de-
cided that they were dead in April and May. This retarding
of leafing due to the defoliation by the caterpillars is just the
reverse of what we see in such trees as pecans and hawthornes.
When these trees are defoliated, in the late summer or early
autumn, by the fall army worm, tent caterpillar or walnut de-
foliator, they are very apt to put out a flush of new leaves in
the fall, which, with pecans, seriously interferes with the blos-
soming and nut setting the following spring.
This damage to the Royal Poinciana, if repeated year after
year, will certainly have a very injurious effect on the trees.
Some trees are killed. We are reproducing a photograph that
Mr. Singleton took of one of these defoliated trees during the
first part of June of this year. This shows a tree in the back-
ground which was not defoliated, with normal foliage. We very
much need to study the life history of this pest and hope that
some of our readers who are located in the region where the
Royal Poinciana grows will make some observations. Its life
history seems to be very interesting. (To be continued)
