LUMINOUS BEETLES OF FLORIDA
To the Editor of The Entomologist:
I have been interested in the habits of various groups of Co-
leoptera for some time, and thought I would write you regard-
ing a subject which might be of interest to the readers of The
Entomologist relative to luminous beetles in Florida. The av-
erage layman is quite familiar with the fact that certain species
of the beetles are luminous and this knowledge is invariaby con-
nected with the group commonly known as "fireflies" or Lampy-
rids. Whenever a beetle flashes a light at night invariably it is
acclaimed a "firefly". In Florida we have two species of lumi-
nous Elaterids scientifically known as Pyrophorus phsoderus
Germ. and Pyrophorus aclanticus Hyslop. I have recently col-
lected a large series of Pyrophorus atlanticus Hyslop in this
section of Florida. The species was observed flying at dusk of
day in fields where species of the so-called "fireflies" were also
present. The distinction between the luminous Elaterids and
Lampyrids is observed in both the location of the luminous or-
gans and their habit of flash. The Elaterids have their light
vesicles situated on the pronotum while those of the Lampyrids
or "fireflies" are situated on the ventral of the posterior seg-
ments of the abdomen. The flash of the Lampyrids is intermit-
tent while at flight while that produced by the Elaterids is quite
constant. It was also observed that the males of Pyrophorus at-
lanticus Hyslop were present in greater numbers on the wing
while those of the opposite sex were scarce in comparison and
were for the most part resting on the foliage displaying a light
at times quite constant, apparently waiting the coming of the
males. The flashes of the Elaterid were only to be observed but
a short while at the dusk of day while the Lampyrids continued
their activities into the night.
We recommend the goods advertised in The Florida Ento-
mologist. Please mention Entomologist when you write our
THE FLORIDA ENTOMOLOGIST
I am merely writing about this subject thinking that it will be
of interest to the readers of The .Entomologist.' Two other spe-
cies of luminous Elaterids occur in the United States, one in
Arizona and the other in Texas, while Florida possesses two spe-
cies. Very truly yours,
G. F. MOZNETTE.

characters but is longer (smaller in most measurements except the abdo-
men); the eyes are not produced on the ventral side; and the intermediate
segments are shorter.
48. Haplothrips graminis Hood.
The author'sAnthothrips floridenis seems to be identical with this spe-
cies and as Hood's description was published a few months earlier it takes

Prothorax very short, less than half as long as the head; sides very
rounding and bearing a thick, heavy spine. Legs moderately long, nearly
concolorous with the body except the tarsi which are lighter. The light
areas on the femora are largest and lightest on the hind femora where
they occupy half of the length and two-thirds of the width of the femora.
They are smaller on the middle femora. Fore femora but slightly enlarged.

collection. Paratype in the National Museum.
This thrips bears a superficial resemblance to H. flavo-antennis (Wat-
son), but it is the apical segments of the antennae which are dark instead of
the basal and the intermediate segments are not elongated.
KEY TO NORTH AMERICAN SPECIES OF HOPLANDROTHRIPS.
In the key to N. A. species of Phloeothrips (Florida Buggist, Vol 1, No 4,
p. 75) those species in Section 1 now go into the genus Hoplandrothrips, as
does also the author's Liothrips flavoantennis. The following additions to
the key will serve to distinguish the species now placed in this genus.
aa. Segment 3 of antennae shorter than 1 and 2 together.
1. Antennae mostly brown or only the bases of 3-7 yellow.
b. bb. and bbb. remain as before.
2. Antennal segments 3-6 light brownish yellow.-H. quercus-
pumulae n. sp.

aaa. Segment 3 about equal to 1 and 2 together, all segments yellow
except 1 and base of 2. Antennae 1 two-thirds as long as head.
H. flavoantennis (Watson)
Myrmecothrips gen. nov.
Head subglobose, well rounded in front and much contracted posteriorly,
much larger than the prothorax, eyes small. Antennal segments, especially
the intermediate ones, all much longer than wide. Mouth cone shorter than
its breadth at the base, reaching more than half way across the prothorax.

enlarged in the males; fore tarsi with a short, blunt tooth in the females.
A large long one in the males. Wings wanting. Abdomen short and thick.
Type Myrmecothrips querci n. sp.
This genus agrees with Uzell's description of Cephalothrips in all char-
acters except the long legs. However, in all other described species of
Cephalothrips the antennal segments are moniliform and it seems undesir-
able to stretch Uzell's description to cover a form so diverse in shape of
head and antennae. Named from its resemblance to an ant.
62. Myrmecothrips querci n. sp.
Female. General color brown, abdomen black with large white spots on
the outer edges of segments 1, 3 and 4. Head dark brown; prothorax a
lighter brown, and metathorax lighter still with a yellow area on the pos-
terior part; legs brown. Antennal segments 1 and 2 light yellow, others

Head subglobose, only a little longer than wide, rounded in front; cheeks
arched and strongly converging posteriorly to a neck whose diameter is only
.6 that of the' greatest diameter of the head, which is directly behind the
post-ocular bristles; post-ocular bristles short (.05 mm.); a little longer
bristle in front of each eye; both light brown and dilated at the tip into a
large colorless head. Eyes small with a few facets.
Antennae 8-segmented; spines few and pale; sense cones short Mouth
cone reaching about .6 distance across prosternum.
Prothorax also subglobose; rounded posteriorly; with a deep constriction
near the middle of each side; covering only the basal half of each coxa;
each posterior angle and each coxa provided with a capitate bristle. Legs
long and slender, nearly uniformly dark brown; fore femora considerably
enlarged near the base, provided with a few knobbed bristles. Fore tibiae
with an especially stout but rather short bristle on the inner side near the
end. Fore tarsi with a short tooth; middle and hind tibiae with a row of
about 8 stiff, pointed bristles along the inner side, the terminal one and
another on the outer side longer than the tarsi.
Abdomen short and thick, abruptly rounded behind the seventh segment.
On side of segment 1 there is an elongated, pearly white area, on segment
3 a similar small round one, and on segment 4 a larger round spot. The
posterior segments bear modestly long, light brown sharp-pointed bris-
tles. Tube short and thick with a terminal ring of 15 bristles, 8 of which
are about as long as the tube.
Male similar to the female, but a little larger. Fore femora greatly en-
larged and tarsal spines very long, stout, and curved.

tal length 0.67 mm.
Described from six females and two males obtained by beating "oak run-
ners" (Quercus pumula) near gainesville, Aug. 2. 11919.
Dolichothrips gen. nov.
Head nearly twice as long as wide and longer than the prothorax, sub-
rectangular in outline, the anterior angles not rounded; sides nearly par-
allel, somewhat narrowed posteriorly. Mouth cone very short and blunt not
reaching the middle of the prothorax. Legs rather short. Wings very short
and feeble. Abdomen exceedingly long and slender.
Type Cephalothrips elongata Watson.
The species used as the type of this genus agrees in every particular
with Uzell's description of Cephalothrips. But the other species of the
genus have a short abdomen and the head is rounded in front. It now seems
undesirable to include a form so diverse in shape of head and abdomen in
that genus. Hind's figure of Cephalothrips yuccae does not show the head
to be rounded in front but all specimens the author has seen show the char-

THE ENTOMOLOGIST is receiving many complimentary letters
on the article by Dr. Hodge in the last number. The awakeping
interest in this most important matter of reducing the mosquito
fauna of our state is indeed encouraging.
In this connection the Jacksonville Times-Union of Sept. 12
has an interesting article on the campaign now being waged to
make the city of Perry an example and an object lesson for the
other cities of the state.
Last month the editor spent an all too brief vacation in one of
our beach resorts. We enjoyed the days hugely; the fish bit
well and the surf was fine. But the nights! Well, it was nec-
essary, soon after sunset, to beat an inglorious retreat to the
shelter of our rooms and stay there. The half hour before retiring
was dedicated to mosquito swatting and it was frequently nec-
essary to repeat the operation between 12 N. and 2 A. M. 'How-
much more attractive would be our resorts would they but spend
a few thousand dollars in cleaning up the local breeding places of
At the "city limits" of many of our towns we see a sign "Wel-
come to Our City". It tickles our vanity to feel that the resi-
dents think enough of us to erect those signs. But, unfortunate-
ly, in many towns the culicidae extend an even more hearty wel-
come, including a reception committee of "prominent citizens"
to meet us the second our car stops.
Now in all this we are not "knocking" Florida but endeavor-
ing to do a little missionary work. If the mosquito were a nec-
essary evil we would be like the "man convinced (by his wife)
against his will", who was "of the same opinion still"- (mighty
still). But the problem in most Florida towns is so simple and
so cheap compared with the interests involved that we feel that
it is the one largest opportunity for real service to the state now
before us. The mosquito is the most powerful "knocker" we
have. Culicid delendus est.
Many of our boards of trade etc. are spending hundreds or
even thousands of dollars and much nerve energy in advertising
their towns. How would it do to spend at least a part of that
money in eradicating mosquitoes and let every delighted tourist
and traveling man advertise our town gratis, especially if we are
going to inaugurate a movement to open the tourist season on
Oct. 1, the very date when mosquitoes are at their maximum
In the review of Applied Entomology (London, Eng.) Vol.
VIII. Ser. B. Part 8, p. 141, occurs an abstract of a paper
by E. Roubaud on the feeding habits of Anopheles in France
The author states that the.malaria mosquito much prefers the
blood of cattle, horses and mules to that of man and that malaria
is on the decrease in those regions where cattle are numerous.
He thinks, however, that this is a recently acquired habit of the
mosquitoes. Some observations along this line in Florida would
be interesting. In any event there is no doubt but that if our
farmers would keep their horses and mules in a tightly screened
barn at night and install one of Hodge's traps in the windows,
they could greatly reduce the numbers of mosquitoes about the
premises; particularly if the house also was well screened.
THE TOILET OF THRIPS
There is at least one thing quite humanly feminine about a
thrips. Her chief concern is for her hairs. When she has noth-
ing else to do, and frequently when to our masculine minds she
has many more important duties, she nevertheless elaborately
brushes and smooths her hairs. There are some minor peculiar-
ities of behavior necessitated by her anatomical plan. The more
important hairs are on her wings instead of her head and she
uses mostly her hind feet for a comb.
Invariably before she can start on a journey or drop in in her
neighbor she must comb her hairs. Even in the face of grave dan-
ger, as the approach of the collector's needle, she cannot take
flight until she has combed her hairs. Combed she must be even
tho the delay proves fatal.
THE FLORIDA ENTOMOLOGIST
The camphor thrips especially spends a goodly part of her
time in-combing her hairs. Even while she sucks the life sap
of a camphor twig her hind legs are busy-combing her hairs.
Having drunk her fill she retires to a shady, secluded nook and,
resting on her four fore legs, doubles her hind ones over her
back and-combs her hair. Watch her under a glass until your
patience is exhausted-she continues to comb her hairs. Go
back hours later-she is still combing her hairs. The
wingless young show none of this concern for their hairs, but
the first act of the adult is to comb her newly acquired wings.
Collect one in a bottle and almost before you can insert the cork
-she is combing her mussed hairs. If caught in a shower her
first act after the rain has ceased is-to comb her hairs. Injure
one mortally and with her last mite of strength she-combs

the outer surface. Fore femora considerably enlarged. Fore tarsi with
a strong curved tooth and a smaller straight one. Wings well developed
but not reaching the tip of the abdomen. Membrane clear in distal half
but the proximal half of fore wing clouded with brownish gray. Fore wing
much contracted in the middle, destitute of prominent veins or bristles;
fringing hairs numerous and fairly long, 4 or 5 interlocated ones.
Abdomen rather long, sub-cylindrical, conspicuous bristles on only the
last two segments but a few of these are quite long, light brown.
Described from two specimens; one obtained from sweeping vegetation
including scrub oak at Daytona Beach Aug. 1919, and another from beating
Basswood foliage Tilia americana at Gainesville, May 1920.
Male similar to the female but the fore femora more enlarged and the
tarsal spine larger.
Described from a single specimen collected from underneath the bark of
an oak tree (Quercus falcata) at Orlando Oct. 1919. Stated by Mr. Funk
of the U. S. Drug Garden who called our attention to this insect, to have
been abundant on the oaks in the spring.

0.17 mm.; prothorax, length 0.20, width including coxae 0.288; mesothorax,
width 0.37 mm.; abdomen, width 0.24. mm. Antennae, segment, 1, 32; 2,
42; 3, 40; 4, 48; 5, 43; 6, 37; 7, 37; 8, 27 microns.
Head 1.1 times longer than broad, sides slightly bulging, parallel or
slightly converging posteriorly, sparsely pilose, post-ocular bristle short and
pointed, not reaching the middle of the eye. Eyes moderately large, occupy-
ing .4 the length and .7 the width of the head. Ocelli large, posterior pair
set in front of the middle of the eyes and touching their margins. Mouth
cone evenly and bluntly rounded, reaching a little past the middle of the
prosternum. Antennae 1.5 times as long as the head; almost uniformly
grayish brown, segment 2 a little darker and segment 3 a little lighter than
the others; sense cones and bristles pale and inconspicuous.
Prothorax shorter than the head, nearly 1.5 times as wide as long, trap-
ezoidal in outline; posterior angles well rounded and each bearing a pair of
heavy but rather short, colorless bristles which are blunt at the end.
Pterothorax sub-rectangular in outline, sides converging slightly pos-
teriorly. Legs moderately long; except the tarsi and fore tibiae which are
lighter brown, concolourous with the body. Fore femora slightly enlarged.
Fore tarsi with a small spine.
Wings well developed. Membrane clear except for a small area at the
base and the scale of the fore wing which are clouded with brown. Fore
wing noticeably contracted in the middle; fringing hairs long, 6 or 7 inter-
Abdomen quite short. The sides of each segment about parallel but ab-
ruptly contracted at the point of contact with the next. Bristles rather
short, tube small, terminal bristles short.
Male similar but fore femora much enlarged and fore tarsal spine robust.
Sides of the head converging posteriorly. Eyes larger.
Described. from a single female and two males beaten from scrub oak at
Daytona Beach, Fla., Aug. 1919. Type in the author's collection. Very
close to H. Graminis but the color is less yellowish brown and the inter-
mediate antennal segments are more elongated, especially the third. There
is a sense cone on the inner surface of the segment 3 but it is thin
and inconspicuous. The most noticeable difference is in the shape of the ab-
domen which is much shorter than in H. graminis.
67. Heliothrips fasciatus.
A single specimen of this species, which is very abundant in California
where it is called the "Bean Thrips" because of its ravages on cultivated
beans, was collected from Cassia at Seabreeze, Fla., Aug. 1919. This was
far from any cultivated land and there can be no doubt that it is a native
insect. This is the second report of its presence in the East, Mr. Mor-
gan having collected it in Tenn.
68. Heterothrips tiliae, n. sp.
Y. General body color dark brown, intermediate antennal segments,
tarsi, tips of all tibiae and entire fore tibiae brownish yellow.
Measurements: Total body length 0.75 mm. Head, length 0.07 mm.;
breadth 0.13 mm.; prothorax, length 0.08, width 0.19 mm.; mesthorax, width
0.23 mm; abdomen greatest width 0.24 mm.; antennae, total length 0.19.
Segment 1 (exposed portion) 9.5; 2, 28; 3, 48; 4, 38; 5, 29; 6, 26; 7, 11;
8, 12; 9, 10 microns.
Head about twice as wide as long, broadest behind the eyes; entire dorsal
surface conspicuously transversely striate; cheeks bearing several short but
stout hairs; frons deeply emarginate at the base of each antenna. Eyes
black, prominent, projecting; hairs between the facets conspicuous, fully
as large as those on the cheeks. Ocelli large, yellow, prominent. Posterior
pair contiguous with the posterior inner angles of the eyes; flattened on
the side next to the eye. Anterior facing forward. Mouth cone reaching
nearly across the prosternum. Antennae almost three times as long as the
exposed portion of the head; 9-segmented; segment 1 cup shaped, 2 and 6
barrel shaped, 3 urn shaped, 4, oblong, 5 ovoid, 8and 9 conical; 1, 2 and 6
to 9 dark brown, 3 to 5 brownish yellow; 3 nearly colorless at the base,
4 shaded with brown on apical half; 3 with two deep constrictions near
the base and many shallow ones above. Bristles and sense cones short and
very inconspicuous, nearly colorless except those on segment 2 which are
larger and brown; segments closely united, articulations brown.
THE FLORIDA ENTOMOLOGIST
Prothorax considerably longer than the head, twice as wide as long, sides
arched and strongly diverging posteriorly; dorsal surface transversely
striated; two or three short, curved spines at each anterior angle; and a
heavy, dark but short one at each posterior angle directed backward. Legs
brown except the tarsi, distal ends of the hind and mid tibiae and the entire
fore tibiae which are brownish yellow; surface marked with diagonal stri-
Mesothorax wider than either the prothorax or the metathorax; anterior
portion of dorsal surface transversely striated, middle longitudinally stri-
ated. Wings considerably longer than the abdomen, membrane brown, cov-
ered with minute hairs, abruptly widened at the base, costal margin sparse-
ly fringed with long hairs and bearing about 28 stout bristles, fore vein
bearing about 14 and hind vein about 19.
Abdomen oval in outline, last segment markedly narrow and elongated,
tubular. Bristles very short, those of the last two segments longer but still
Male. Considerably smaller. Body length 0.50 mm. Head 0.047 mm.
long and 0.14 mm. wide; prothorax, length 0.095 mm., breadth 0.18 mm.;
m6sothorax, greatest width 0.2 mm.; abdomen 0.14 mm. Antennae, seg-
ment 1, 10; 2, 28; 3, 50; 4, 36; 5, 30; 6, 27; 7, 12; 8, 14; 9. 11 microns.
Striations on the head and prothorax are less marked. Abdomen very
small, scarcely twice as long as wide. Wings much exceeding the abdomen.
Described from a singe female and a single male collected from Bass-
wood (Tilia americanna) at Gainesville, Fla., May.
This species is very close to Heterothrips vitis Hood but is smaller, lacks
any suggestion of orange on the third antennal segment which is much
shorter as is also the prothorax, and the forth antennal segment is also
yellow. Type in the author's collection.
