SPINED SOLDIER-BUG REARED ON CELERY LEAF-TYER
By DAYTON STONER,
U. S. Bureau of Entomology
In the course of some insectary experiments conducted with
possible predators of the celery leaf-tyer (Phlyctaenia rubigalis
Guen.) at the United States Entomological Field Laboratory,
Sanford, Florida, certain observations concerning the habits and
biology of the spined soldier-bug (Podisus maculiventris Say)
were made.
On December 13, 1928, a female Podisus maculiventris, taken
on a celery plant in an old seed bed, was placed in a small jelly
dish in the insectary with three pupae and a half-grown larva
of the celery leaf-tyer. Two days later moths had emerged from
two of the pupae and the bug held one of the newly-issued moths
impaled on her beak and was sucking its body juices.
Until the time of the soldier-bug's death on January 10, 1929,
it had fed upon three larvae, a pupa, and two moths of the celery
leaf-tyer together with a larva of the southern beet webworm
(Pachyzancla bipunctalis Fab.). It had been in captivity 27
days.
A day before the bug died it laid a mass of 22 eggs on the
4loor of the cage. The eggs proved to be fertile and hatched
within 11 days. When first noticed, the nymphs were congre-
gated in a compact group near the top of the cage. On subse-
quent occasions they exhibited a tendency to mass together in
this way even when only three survivors remained in the dish.
Although a number of small celery leaf-tyer larvae were con-
tinuously available as food for the nymphs, the latter did not feed
on them until 15 days after hatching. However, in the mean-
while the nymphs molted once and some of them were observed
to have their beaks inserted into the petiole of a sprig of celery
that had been introduced into the cage as food for the tyer

larvae. Cannibalistic propensities were exhibited by the Podisus
nymphs, for by February 4, 15 days after hatching, only three
were alive and one was discovered with the body of another
but smaller nymph impaled on its beak. Their gregarious habits
appear to be conducive to cannibalism, at least in captivity. On
February 22 the smallest of the survivors died, leaving only
two of the original 22 alive.
On one occasion, while one of the nymphs was quietly sucking
the body juices of a leaf-tyer larva, the other two nymphs ap-
proached and began feeding upon the same larva and each tug-
ged and hauled about in an apparent effort to pull it away from
the others.
After the nymphs were about 10 days old they were not ob-
served to feed upon the juices of the celery sprigs that were
introduced into the cage as food for the larvae, but several celery
leaf-tyer larvae, in the third to fifth instars, were destroyed by
the bugs.
Three weeks after the bugs hatched a newly emerged celery
leaf-tyer moth was placed in the cage where it remained for
two days before one of the nymphs fed on it although during
this period larvae had been fed upon. From this time moths
were introduced at frequent intervals for food of the rapidly
growing nymphs and were fed upon freely. For a number of
days a live but naked celery leaf-tyer pupa lay untouched on the
floor of the cage but on February 25, when the bugs were 32
days old, this, too, had been sucked dry. On February 26 the
larger nymph had molted for the last time, 33 days having
elapsed since it had hatched; and two days later the smaller
nymph transformed to the adult having completed its cycle in
35 days from the time of hatching.
The observations indicate that Podisus maculiventris may
breed throughout the year in central Florida. The mean tem-
perature out of doors during the incubation period was 650 F.
While this pentatomid does not appear to be of frequent oc-
currence on celery in the Sanford district, wherever it is present
it may be of value in destroying one of the most noxious insect
pests of that plant-the celery leaf-tyer.

ANOTHER IMPORTED ANT
M. R. SMITH
A. & M. College, Mississippi
Probably no state in the union has a larger number of intro-
duced ants than Florida. This peculiar condition is no doubt
due to a number of causes, chief among which may be enumer-
ated the following: (1) that Florida is constantly being visited
by many tourists; (2) being a seaboard Atate she is in direct
communication with many foreign ports; and (3) on account
of the semi-tropical climate nearly any ant that is imported into
her borders is almost sure to thrive outdoors.
Some of the imported ants that have been noted to occur in
this state are the following: Monomorium pharaonis (Linn.),
Solenopsis geminata subsp. rufa (Jerdon), Tetramorium gui-
neense (Fabr.), Wasmannid auropunctata (Roger), Tapinoma
melanocephalum (Fabr.), Paratrechina longicornis (Latr.) and
Camponotus socius Roger. That the Argentine ant Iridomyrmex
humilis Mayr has not yet been recorded from Florida is indeed
remarkable.
Recently I received for determination a number of specimens
of ants which were collected at Miami, by Mr. S. O. Hill. Among
the lot was one species which I had never seen before from North
America. With the available literature the ants were determined
as a species of Paratrechina (Nylanderia). Realizing that the
species was no doubt either a new species or else an imported
one, very. probably the latter, I submitted specimens to Dr.
Wheeler who identified the ants as a variety of Prenolepis

THE FLORIDA ENTOMOLOGIST

(Nylanderia) bourbonica, Forel, the type of which is known
from Madagascar. This variety was very probably introduced
into Florida on plants.
Mr. Hill in remarking about the habits of the ants stated that
the workers were observed running over sand and the pavement
of sidewalks at Miami. It would appear that this species is not
only well established at Miami but that it is capable of living
outdoors. Whether the species will prove to be a house infesting
form is not known, but it would appear that there might be a
strong possibility of this since a number of our native Para-
trechina (Nylanderia) have this habit.
Following is the synonymy of the species: P. bourbonica

AN OUTBREAK OF THE CORN SYRPHUS FLY
By J. R. WATSON AND A. N. TISSOT
The larvae of Mesogramnna polita Say, have food habits very unusual
for a syrphus fly, most of which feed on aphids and other small insects,
tho some are scavengers. The larvae became extremely abundant in a corn
field near Waldo, Fla.. in early June. They appeared in such large num-
bers on the tassels and the leaves as to attract attention of the owner of
the field and cause him considerable alarm. In response to an S.O.S. from
him, the field was visited by the writers. By that time the larvae had almost
disappeared; only one was seen. But there were large numbers of pupae,
especially on the leaves. In some cases as many as five pupae were taken
from a single leaf.
In Insect Life, Volume I, p. 5, there is an account under the name of
Mesograpta polite, of two similar outbreaks of this syrphus fly. One in
New Jersey and the other in Florida. In the previous outbreak in Florida,
the larvae were observed to be feeding upon the stalks of corn where they
caused soft discolored places. In the New Jersey outbreak they were re-
corded as feeding exclusively on pollen. In the field at Waldo no damage
to the stalks was seen. The larvae apparently confined themselves exclu-
sively to pollen. They had fed extensively on the tassels, and those found
on the leaves had undoubtedly been feeding on pollen grains which had
fallen there. They had caused no apparent damage to the corn. It seems
probable that this insect is by preference a pollen feeder and feeds on the
other parts of corn only when forced to do so by hunger. A noteworthy
characteristic of this outbreak was the fact that the maggots appeared
in such large numbers suddenly and disappeared as suddenly. Twenty-four
hours after the farmer had first noticed their presence on the corn, they
had almost entirely disappeared, although plenty of adults were found
flying about. Puparia collected from this field were found to be highly
parasited by two as yet undetermined species of Hymenoptera.

In addition to the above S. julianus Burm. has been recorded
by Wickham from Sevenoaks. As the species is definitely known
only from Mississippi to Texas, the record was probably based
on a specimen of antaeus.

neath old logs; abundant beneath arc-lights in July" (Doz.).
Lake Butler (Ag. Coll.); Tampa and Elford (P. B. Coll.). Or-
mond, June 11; Dunedin, June 15; at light (B1.). Apparently
more scarce in Florida than in southern Indiana, where it is of
frequent occurrence. It is the largest Scarab found in eastern
North America and gives off a strong but not unpleasant odor
when handled. The larvae are said to live in rotten wood.

Genus XLVIII. PHILEURUS Latreille.
Elongate-oblong, subdepressed black beetles of large or me-
dium size, resembling Passalus and having the head and thorax

turned, obtuse; thorax three-fifths wider than long, its apical third gradu-
ally declivent, its punctures coarse, crescentic, each enclosing a fine punc-
ture, the tubercle placed near its front margin; basal half of scutellum
with numerous punctures; elytral striae coarsely punctate, intervals alter-
nating in width and height.
Tampa and Enterprise, rare (Sz.). Everglade and Big Pine
Key (Dav.). Dunedin, June 4, at light; Dec. 24, burrowing in
sand near fresh cow dung; R. P. Park, March 18 (B1.). This is
the P. floridanus Csy. (1915, 270), evidently described from a
single Florida male. While he makes some general remarks re-
garding valgus he does not include it in his key, nor give any
characters separating his species from it, though he makes the
P. castaneus Hald., from Alabama, a synonym of it. The same
form as that found in Florida, occurs quite frequently in south-
ern Indiana, so that Casey's name, even if valid, is a misnomer.

Subfamily CETONIINAE
Medium sized somewhat rhomboidal Scarabs more or less
flattened above and having the mandibles feebly developed, usu-
ally concealed; front coxae conical, prominent; antennae 10-
jointed (9-jointed in Roplisa), club 3-jointed; pygidium exposed;
tarsal claws simple and equal. In certain genera the side pieces
of the mesosternum (mes-epimera) are projected upward to
form a small plate visible from above at the shoulders between
the thorax and elytra. In flying the Cetonids only partially
raise the elytra and slip the inner wings out from the side. They
feed for the most part on pollen, the sap of trees, or the juices
of fruits, fly about by day and at night or in rainy weather con-
ceal themselves beneath loose bark or other cover.

KEY TO TRIBES OF FLORIDA CETONIINAE
a. Mes-epimera visible from above; elytra sinuate on the sides behind the
humeri.

Probably occurs throughout the State. Recorded by Wickham
from Enterprise as E. fulgida but that species is of more north-
ern distribution.
*178. (13940). E. inda Linn.
Length 13-16 mm. Oblong-oval, narrowed in front; thorax, stern and

"Rare" (Sz.); Lake City (Ag. Coll.); Lake Okeechobee and
Winter Haven (P. B. Coll.). Gainesville, Oct. 9; "occurs on blos-
soms of various plants but uncommon" (Doz.). Dunedin, taken
but once, Jan. 22, while sweeping in a garden (B1.).

179. (13952). E. nitens Csy.
Length 11.5-14.5 mm. Oblong-oval; above black, very shining, glabrous
and with a strong deep blue tinge, rarely greenish; under surface and legs
shining black, the sterna sparsely pubescent; clypeus as long as wide, sides
parallel, apex obtusely rounded; thorax and elytra coarsely sparsely punc-
tate, the latter with a few vague whitish or tomentose lines or spots.
This is the E. melancholica Horn, nec. Gory, and is listed by
Schwarz as "common"; also by Hamilton from Lake Worth,
and by Schwarz (Ms.) from Biscayne Bay, but it was probably
confused with sepulchralis and its occurrence in the State is
very doubtful, its main distribution being from Kansas to Texas
and Mexico.

*180. (13953). E. sepulchralis (Fabr.).
Length 10-14 mm. Oblong or oblong-oval; above dark brownish-bronzed,
feebly shining, sparsely pubescent; sides of thorax with a submarginal
whitish tomentose line; elytra with numerous short sinuous transverse
whitish lines; under surface and legs polished black with a coppery tinge;
clypeus as in nitens; disk of elytra with two obtuse costae the sides trans-
versely rugose; antennal club of the sexes subequal in length.
Common throughout the State, especially so in spring on the
heads and in the leaf axils of thistles. Recorded from 14 sta-
tions, and at hand from seven others. The description of the
var. floridana Csy. (1915, 32) has no fixed characters to sepa-
rate it from the typical form, and the name is superfluous.

Genus LI. STEPHANUCHA Burmeister.
Species closely allied to Euphoria, and by Horn and most
American authors, placed under that name. They differ in hav-
ing the body more convex, and especially in having the apex of
clypeus with four small spiniform teeth, the two median ones
somewhat closer and arising from a common base; thorax with
base rounded, not sinuate as in most species of Euphoria.

SUMMER NUMBER

Genus LV. TRIGONOPELTASTES Burmeister.
Rather small, oblong-oval species, having the upper surface
subglabrous and opaque; thorax black, with a large reversed
deltoid yellow impression on middle; elytra, as in the next genus,
conjointly not longer than wide; front tibiae bidentate, male,.
tridentate, female.
*188. (14015). T. delta (Forst.).
Length 7.8-10 mm. Head black; clypeus and a transverse line between
eyes, yellow; thorax black, all the margins and the deltoid impression, also
two spots on scutellum and a line behind it, yellow; elytra reddish-brown,
each with an oblique wedge-shaped spot between humerus and suture, and
two spots on apical half, black, these spots variable in form and size; pygi-
dium and under surface densely clothed with yellow scales, the former
with median line and apex usually naked.
Frequent throughout the State, occurring from March to De-
cember. At Gainesville it was found on chinquepin blossoms,
April 28, and on flowers of Salvia, Cherokee rose and goldenrod
from June to August (Doz.). At Dunedin and R. P. Park it was
taken from flowers of various kinds, March-December; frequent
at light in June.

Genus LVI. TRICHIOTINUS Casey.
This genus comprises the species formerly listed under the
name Trichius. They are oblong, subdepressed species differing
from Trigonopeltastes mainly in lacking the deltoid impression
of thorax and in having the front tibiae bidentate in both sexes.
The thorax is narrower than elytra, rounded at base and, as well
as the head and sterna, thickly pubescent with suberect hairs.
They occur on flowers during the day and fly quickly when ap-
proached.
189. (14016). T. piger (Fabr.).
Length 8.5-11 mm. Head and thorax piceous or greenish; elytra red-
dish-brown to piceous, each with two short oblique whitish bars on side,
the space between and behind these blackish; body beneath and pygidium
rufous; elytra in this and the next three species each with two obtusely
convex costae, the flat intervals between them finely and densely punctate;
pygidium and under surface reddish-brown, the former thickly pubescent
and with a white scaly patch at sides; front tibiae of male in this and
texanus without a spur.
Common (Sz.); Crescent City and Tampa (Wick.); St. Aug-
ustine (Fall); Gainesville, May-June, on flowers of Jersey tea,
magnolia, etc. (Doz.); Enterprise (Dietz); Wauchula on wild
rose (Ag. Coll.).

Length 10.5-12.8 mm. Deep black and shining throughout, the elytra
with pale bars on sides long and oblique as in piger; pygidium with an elon-
gate spot of white scales each side; front tibiae of male with inner edge
very broad.

short narrow white bars on sides of elytra a darker brown; pygidium almost
devoid of hairs, the sides each with a dense elongate-oval patch of white
tomentum; thorax narrow, scarcely as wide as long, evenly and closely
punctate throughout.
Gainesville and Enterprise (Dietz); Marion Co., Florida, 12
males (Csy.); Dunedin, March 30-April 13 (Bl.).

lustre; elytra black, the disk in part reddish-brown, the area between and
behind the pale transverse bars on sides always black; pygidium piceous
or rufescent, with pubescence as in rufobrunneus; thorax distinctly wider
than long, the disk rugose-punctate in front, sparsely punctate near hind
angles.
Type from Jacksonville (Csy.). Enterprise (Dietz). Ormond,
April 14, Dunedin, April 12, on flowers of wild plum; June 10
at porch light (Bl.).

193. (14025). T. affinis (G. & P.).
Length 8-9.3 mm. Oblong-oval; head, thorax, unddr surface and legs
black with a greenish tinge; elytra usually in large part reddish-brown,
the sides black with the usual two oblique whitish lines and black velvety
space between and behind them; head densely, thorax more sparsely punc-
tate, the latter with a median impressed line; second and fourth intervals
of elytra sparsely punctate; third and fifth in this and the remaining
species but feebly convex; pygidium nude at middle, the apex, base and
white tomentose areas on sides with numerous long white hairs.
Enterprise (C. & L.). La Belle, April 27, common; Deep
Lake, April 12-14 (Day.). As the usual distribution of affinis
is more northern, these records may belong to T. obesulus Csy.

*194. (14027). T. bibens (Fabr.).
Length 10.8-12 mm. Head, thorax, body beneath and legs, bright metal-
lic green; elytra reddish-brown, with umbone, and often a spot at apex,

pale transverse lines of elytra more distinct, the hind one much longer;
pygidium with lateral tomentose areas larger, almost meeting across the
base.
