Notes on Dinapate wrightii Horn (Col.).*
By Ricuarp T. GARNETT, Oakland, California.
(Plate II.)

This extremely rare Bostrichid, called by Hubbard the
“dodo” of Coleoptera, was taken by the writer in Palm Can-
yon on May 21 and 22, 1917. Every dead or unhealthy speci-
men of the palm, I’ashingtonia filifera, in Palm, Murray, and
Andreas Canyons was thoroughly examined. Of these only
one log in the extreme lower end of Palm Canyon contained
the beetle. This log, covered by driftwood, was wedged into
a crevice in the rock strata fifteen feet above the summer

stream level. From this log on the days mentioned 13 33, adults,

28 pupae and 17 larvae were taken. Of the adults 81 were
males and 52 females. When the log was discovered, one
adult had made its exit, as was shown by the freshly bored
exit hole. The colony therefore totaled 179.

Many other logs in these three canyons had exit holes in
them, but with the exception of the one above noted all were
black with vears of weathering. The average number of exit
holes, making a count of 20 trunks, was 14, the highest num-
ber being 21 and the lowest 2. A great many must perish and
decay in their pupal cells if the colonies average anywhere
nearly as many as the one which I found.

A few of the adults were yet soft from their change from
the pupae, but the majority were hard and would undoubtedly
have emerged in 7-14 days. Thus, if there are any survivors
of this species, the time of emergence must be the latter part
of June or the first part of July.

The galleries of the fully grown larvae averaged 18 mm. in
diameter. . This diameter was exceptionally constant for larvae
of the curled type. The galleries crossed and recrossed each
other in a confused manner, practically destroying all fibre
in the region attacked, the powdered material being packed ex-
tremely compactly. The galleries never approached closer
than an inch to the hard outer layer of the trunk and the very
centre of the log for six inches in diameter was untouched.
All the wood in between was completely riddled by the bor-
ings. The larvae were working usually at a depth of about
3 to 7 inches beneath the surface. Although the position of
the log may have had something to do with it, almost all of
the pupal chambers were either parallel to the surface of the
log or nearly so. The exit holes were being bored almost
perpendicularly from the pupal chamber to the outside.

Two of the larvae were of a much smaller size than the
rest, thus tending to show that the life cycle is at least of two
years’ duration.

The weakening of the trunk by the galleries often causes
the trees to fall, 19 logs occurring in Palm Canyon alone. A
great many of the standing trees have exits visible on them,
but usually only two or three per tree, most of them situated

ols xxix | ENTOMOLOGICAL NEWS. 43

within ten or twelve feet of the ground, although a few were
noted near the tree crown. When occurring in prostrate logs,
the exit hcles seemed to be indiscriminately dispersed.

The attacks of this beetle are not always fatal as is shown
by a number of standing and perfectly healthy trees with exit
holes on their boles. If these holes are numerous the tree is
generally dead.

In the larval, and possibly the pupal, stages this insect must
be very resistant to water, as the log had apparently broken
off at the roots during the winter of 1916, been carried down
the canyon and jammed into the crevice by the high water. In
this journey down the stream the water must have seeped into
the interior of the log. A live larva was placed in water and
was drowned in 28 minutes. This, however, is a more severe
test of vitality than the water-soaked log was. A live adult
was drowned in 15 minutes 35 seconds. Three hours in a
strong cyanide bottle was insufficient to kill three of the adults.

Larva—Robust, ventrally flat, dorsally convex; yellowish white,
mandibles black; 9 abdominal segments, 3 thoracic; clypeus white,
labrum darker and on anterior two-thirds densely, finely ciliate; labium
and maxillae white with a line along their base chitinized; antennae
3-jointed, bisetose at tip. Body covered with short fine silky brown
hair; body resembles that of a “white grub” being curled, however,
the anterior segments are much the larger. Legs apparently 3-jointed
(Horn says with 4 articulations), tarsal claw one and cleft. Length
46-63 mm. (All measurements following are from the anterior mar-
gin of the thorax to the tip of elytra.)

Pupa.—Resembles the adult, white; head, thorax, and elytra smooth,
the latter bent under the abdomen between the middle and hind pair
of legs; the most prominent costae and tubercles usually visible on
the elytra; dorsal surface of the meso- and meta-thorax and of the
abdomen visible; scutellum prominent; a row of fine recurved teeth
across the dorsal side of each abdominal segment except the last, each
row situated nearer to the posterior edge of the segment than to the
anterior and on an elevated ridge; abdomen g-segmented; on the
end of the abdomen is attached the shriveled larval skin, the mandibles
on the ventral side. Length 42-64 mm., width 15-20 mm.

Adult—Cylindrical, shining black; head concealed from above by
the thorax; antennae 10-jointed, first joint elongate and stout, over
twice as long as the second joint which is also stout; joints 3 to 7
smaller and equal; joints 8 to 10 much wider and clavate, 8 and 9

A4 ENTOMOLOGICAL NEWS. [Feb., 18

triangular, 10 more rounded. Eyes large, prominent. Labrum dis-
tinct, anteriorly ciliate with silky brown hair.

Thorax very~convex, sparsely clothed laterally with short brown
hair; middle of anterior portion without the distinct bulge shown in
Horn’s figure of adult female; posterior half granulate with a median
longitudinal sulcus smooth; anterior half with recurved dentate tuber-
cles (teeth less pronounced in the females), the extreme anterior edge
granulate only.

Elytra shining, glabrous; costae 4, the 2 outer indistinct; intervals
of inner 2 costae foveolate, smoother towards sides; the 2 inner
costae terminate in a tubercle (female), and in a robust tooth (male).
Elytra bent downward behind the upper tubercle at an angle of
45-60 degrees. The declivity smooth in the male, granulate in the
female.

Abdomen 5-segmented, all segments equal and fully visible; entire
ventral surface covered with fine silky brown pile.

Legs more or less covered with hair, front coxae prominent, coni-
cal, trochanters prominent, femora stout, tibiae flat and acutely dentate
externally, tarsi 5-jointed, claws simple and arcuate, 5th tarsal joint
with a bristle-bearing pad.

Length 38-51 mm.; width 14-18 mm.

The adult is lumbering in its movements and has poor eye-
sight as one of the beetles escaped and while in flight collided
with anything that came in its path, making its recapture easy.
Although the wings are well developed, the heavy body im-
pedes swift and unerring flight.

Selenis sueroides (Lep.).

Mr. J. G. Bonniwell has recently sent me a specimen of Selenis mon-
otropa Grote. It is labeled, “Bradentown, Florida, ex larva, August
17th.” Mr. Bonniwell says: “My wife and IJ have raised quite a few
of these from the larvae. It feeds on a variety of ‘sensitive plant’ and
penetrates the stem to make its pupa.” The species was described by
Grote in the Canadian Entomologist, 1876, vii, 209, from Texas. We
have specimens of the same moth from Cuba, in the Poey Collection,
under the name, Selenis sweroides Guénée. Sueroides was described
in 1852—HENrY SKINNER.

bristles; middle and hind coxae black; femora yellow, their tops black-
ish; tibiae yellowish, the hind pair darkened towards their tips; tarsi
darkened from the tip of the first joint; middle femora with a small
bristle on each side near the tip; fore femora with delicate hairs on

tinged with gray, slightly brownish in front of the second vein;
second and third veins slightly diverging; fourth vein parallel with
third and ending in the apex of the wing.

9—Differs from the description given above in not having the
femora blackened above except the hind pair at tip; the front tarsi
are plain; the face wider; and third antennal joint much smaller.

Described from one male and one female in my collection,

taken at Los Cerritos, Los Angeles County, California, March
2ist.

46 ENTOMOLOGICAL NEWS. [Feb., 18

Hercostomus unicolor Loew.

Dr. J. C. Bradley took two males at Blue Lake, Humboldt
County, California, and a female which seems to belong to
this species in Colorado. I took both males and females at
Kearney, Ontario. Loew described it from Hudson Bay, and
Wheeler from Wisconsin.

Asyndetus appendiculatus Loew.

Dr. J. C. Bradley took a male of this interesting species
at St. Petersburg, Florida, August 10, 1910. Loew described
it from Rhode Island.

Tachytrechus laticrus Coquillett (Figs. 3, 4).

é—Length 5.5 mm. Face covered with yellow pollen which gives
it a velvety appearance, rather narrow in the middle; palpi and pro-
boscis black; antennae wholly yellow, third joint rather small, slightly
pointed; arista black, dorsal, with a small lamella at tip, about as
long as the height of the head; front black, dulled with yellowish
pollen; ocellar tubercle prominent with two large bristles; orbital cilia
black.

Thorax metallic black with bluish reflections on the dorsum, shin-
ing but dulled with brown pollen on the dorsum and silvery pollen
on the pleurae; this white pollen extends along the front over the
humeri but is interrupted before reaching the acrostichal bristles, these
bristles small but forming two close set rows which reach a little be-
yond the middle of the dorsum; scutellum black with a slight de-
pressed, pollinose space on each side, leaving a flat, shining, raised
space in the center.

Abdomen metallic greenish black with considerable white pollen on
the sides; hypopygium rather large, black, shining on the inner side,
covered with whitish pollen on the outer surface; lamellae nearly

round, black, fringed with black hairs, inner appendages shining
black.

Coxae black, with white pollen; fore coxae with yellow pollen and
black hairs and bristles on the front surface; femora greenish black
with white pollen, the extreme tips yellow; fore tibiae pale yellow with
white pollen, much flattened on the distal two thirds (Fig. 3),
inner edge of the flattened portion black and densely fringed with
flattened, black bristles, near the base a more or less distinct brown
ring; middle tibiae more or less yellow towards the base, sometimes
mostly black; hind tibiae and tarsi black; middle tarsi somewhat
yellowish at base: fore tarsi with the first joint mostly yellow, the
following joints brown, last tarsal joint as figured (Fig. 4), claw
with a very small tooth at base which would be difficult to see if the
claw was not in a favorable position.

Halteres reddish yellow; tegulae pale yellow with black cilia. Wings
grayish hyaline, slightly darker between the second and third veins;
tips of the third and fourth veins nearer together than in the other
eastern species, about as in T. olympiae Ald.

9—As in the male except that the face is wider; arista plane, nearly
as long as the face; pollen of the face and fore coxae white; fore
tibiae plane, rather stout, yellowish, more brown towards the tip, with
three large bristles on the inner and five on the outer surface (in one

specimen there is an extra bristle on the inner side of one tibia);
ovipositor black.

My specimens were taken by Mr. Harbeck at Manahawkin,
New Jersey, Julv 30th.

I publish this as I cannot find any record of Mr. Coquillett’s
describing it, and probably it is only a manuscript name. I
am using the name he gave so as to save confusion, as this
species has gone into several collections under this name.

Paraclius nigrocaudatus sp. nov.

ing the third almost from the cross-vein, but not forming an angle
where it bends forward, its tip near the tip of the third vein, and
far before the apex of the wing: last section of fifth vein about two
and a half times the length of the cross-vein.

Described from one male taken at Beaver Creek, Montana,
in August, by S. J. Hunter, at an elevation of 6300 feet.

This species and also P. flavicornis sp. noy. described in
this paper have the venation something like that of a Mede-
terus, but the other characters are those of a Paraclius.

and with a cluster of bristles on the inner side near the base.

Tegulae and their cilia brownish yellow; halteres yellow. Wings
smoky, an indistinct brown cloud on the posterior cross-vein; veins
black; first vein short; second vein long, extending out towards the
tip of the wing and beyond the tip of the first vein running close to
the costa until it merges into it; last section of fifth vein equal to the

50 ENTOMOLOGICAL NEWS. [Feb., 718

Abdomen green with coppery reflections and stiff black hairs, dusted
with white pollen which is more dense on the sides.

Fore coxae clothed with long bristle-like hairs on the front surface;
middle and hind coxae also with stiff black hairs; fore femora a
little enlarged at base and with rather long black hairs, but without

Angeles County, February 28th. All were taken on salt
water. Type in my collection.

This species runs in Prof. Aldrich’s key (Psyche, Vol. xviii,
p. 48) to H. gratiosus Ald., but is quite distinct, the shining
green face, crooked fore tibiae and metatarsi and the second
vein of the wing running so close to the costa make the male
easily recognizable; the female can be separated by the black
hair of the fore coxae and tegulae.

on inner surface.

Vol. xxix] ENTOMOLOGICAL NEWS. 51

Knob of halteres yellow, stem darker. Wings tinged with grayish
brown; a distinct hyaline spot back of the base of the fifth vein and
brown clouds on the cross-vein and middle of the last section of
fourth vein.

Described from two males from California; one taken at
Los Cerritos, Los Angeles County, March 21st, the holotype
at Berkeley, Alameda County, May 27th. Type in my collec-
tion.

A female, taken at San Diego, California, on April 25th,
may belong to the same species but has the pollen of the face
more yellowish or brownish yellow, but otherwise about as in
the male.

This species is quite distinct from H. intentus Ald., although
this difference is difficult to put into words, but intentus is
covered all over with a distinctly yellow pollen, while in this
species the pollen is more gray, that of the face is silvery or
only a little yellowish at most. This species is also a little
stouter than intentus.

Corrections to ‘New York Scolopostethi” (Family
Lygaeidae: Heter.).
By H. G. Barser, Roselle Park, New Jersey.

In the February, 1917, number of ENTomMoLocicat News,
pp. 65-68, appeared a paper on the “New York Scolopostethi”’
by J. R. de la Torre-Bueno, in which occur a number of grave
errors which need correction. The sub-family Aphaninae or
Rhyparochrominae (page 65, lines 18-23) is characterized by
having the suture between the third and fourth ventral seg-
ments (not the second and third) more or less curved. The
tribe Lethaeini (page 65, lines 23-26) was separated by Stal
from the other tribes or divisions because of the position of the
posterior glandular opaque spot on both sides of the fourth
ventral segment, which in this case is placed closer to the an-
terior spot, far removed from the posterior margin of the seg-
ment. In 1913 Dr. Bergroth called in question the tribal value
of these glandular spots, so far at least as the Lethaeini of

the world are concerned, and advocated uniting this tribe
with the Rhyparochromini. However, the consideration of
the position of these glandular spots as a tribal character for
our United States Lethaeini certainly succeeds in grouping
together, without other characters, a fairly well unified group
of genera.

In his synoptic key (pp. 66-67) for separating the three
species of Scolopostethus, Mr. Bueno, in following Horvath
1893, perpetuated his error in reference to the ocular setae.
Dr. Horvath, in Rev. d. Entomol., XII. pp. 238-241, 1893,
published a description of the three American species of Scolo-
postethus, remarking that S. atlanticus and S. diffidens difier
from the introduced European S. thomsoni by the absence of
the two setae placed near the eyes. As a matter of fact all
three species possess these setae. It is also inadvisable to use
claval punctures for specific diagnosis. The spines of the
fore femora are more dependable as a specific character, but
these are subject to considerable variation.

The following key will serve to differentiate the three spe-
cies of Scolcepostethus :

1 (4). Hemelytra strongly fasciate with fusccus posteriorly.

2 (3). Membrane commonly juscous, variegated with pale, with a
large pale spot on each side in macropt. form. Lateral margins
of pronotum straight. Anterior femora armed with smaller spines
only towards apex from the larger spine....S. atlanticus Horv.

3 (2). Membrane in macropt. forms commonly pale with the veins
fuscous and without the pale spot on each side. Lateral margins
of the pronotum obviously concave. Anterior femora armed with
smaller spines both before and behind the larger preapical spine,

S. thomsoni Reut

4 (1). Hemelytra not strongly fasciate with fuscous posteriorly,
merely slightly embrowned. Lateral margins of the pronotum
nearly straight. Membrane dark brown with a pale spot on each
side in both macropt. and brachypt. forms....S. diffidens Horv.

Mr. de la Torre-Bueno has one of the specimens from Colo-
rado recorded by Uhler in Gillette and Baker’s Henuptera of
Colorado, 1895. as Eremocoris tropicus Dist. This particular
specimen is S. thomson Reut.

New Species of Buprestidae (Col.) from the Pacific
States—No. 2.

By Epwin C. Van Dyke, University of California, Berkeley,
California.

The following descriptions are in the way of a supplement
to some species described in a previous paper.’
Poecilonota bridwelli n. sp.

Elongate-oval, sub-depressed: brassy green with the exception of the
antennal and tarsal joints which show a cupreous tint; the front and
prosternum moderately densely clothed with long white hair, the
surface elsewhere including the pronotum and elytra more sparsely
clothed and with shorter and more depressed pile; the depressed areas
above and the greater portion of the under surface coated with a
white powdery substance; antennae not reaching hind margin of pro-
notum; front slightly sulcate and coarsely punctured; pronotum less
than three-fourths as long as broad, side margins almost straight and
parallel for posterior three-fourths then gradually rounded to apex,
disc with a smooth median elevated longitudinal line extending from
base to apex and broadest at middle, with a shallow and equally broad
depression on either side, a secondary, punctured, and irregular ridge
outwardly bounding these, the sulci and sides coarsely and cribrately
punctured; elytra three times as long as pronotum and slightly broader
at humeri, side margins almost straight and parallel for anterior two-
thirds, thence suddenly narrowed and slightly sinuate to apex, the tips
hardly prolonged, but slightly divergent, and truncate at apex, the disc
with intervals 1-5 distinctly elevated, rounded, and continuous through-
out greater portion, intervals 7 and 9 equally elevated but frequently
and broadly interrupted, intervals 6, 8 and ro less evidently elevated and
more interrupted, the more continuous intervals coarsely punctured at
irregular distances, the striae finely punctate; the underside in front
rather finely and sparsely punctured in median area and more coarse-
ly and cribrately so at sides, the abdomen with a smooth area down the
middle and with sides coarsely and aciculately punctured. Length
13 mm., breadth 4.5 mm.

&. Prosternum rather densely clothed with long silky white hair
and the last ventral deeply and broadly emarginate.

Q. Prosternum less densely clothed and with shorter hair and the
last ventral with small triangular incisure

The description given above was based upon a single male.

New Srcies of Buprestidae (Col.) from the Pacific States, by
Edwin C. Van Dyke, Entom. News, Vol. XX VII (1916) pp. 405-412.

54 ENTOMOLOGICAL NEWS. [Feb., 18

The only other specimen seen, the companion female, differs
somewhat as regards the sculpturing of the elytra, all of the
intervals here being broadly and frequently interrupted so that
they present a chain-like or catenulate appearance instead of
the more or less regular one which is observable in the male.

This species differs materially from our other species, by
its uniform brassy green color, its more evident hairiness, the
more distinctly defined longitudinal sulci of the pronotum,
and the greater elevation of the elytral intervals, resembling
in this last regard some of our Dicercas, such as D. tenebrosa
Kirby.

Type male and female from Imperial County, California,
June, 1911, collected on flowers by Mr. J. C. Bridwell. The
type male is in my own collection, the type female in the collec-
tion of the University of California. The species is named in
honor of the collector.

Melanophila californica n. sp.

Elliptical, sub-depressed; bronzed above, brassy green beneath; with
minute, short, erect, white hair sparsely scattered over the elytra, denser
and more oblique on under side of body; front of head convex, shining,
densely, coarsely and closely punctate, the median punctures some-
what elongated; pronotum two-thirds as long as broad, widest near
base, distinctly narrowed in front, sides feebly arcuate, hind angles
acute, marginal line obliterated in front, disc rather evenly, coarsely,
closely and regularly punctured, the punctures rarely confluent; elytra
three times the length of pronotum and but slightly broader, densely
granulate-punctate, without costae, lateral margin finely serrulate
towards apex, apices obtuse; beneath coarsely and densely punctate
in front and more finely and sparsely behind; tip of prosternum sud-
denly constricted; last ventral segment obtusely rounded, with a sub-
serrate ridge below the side margin near the apex; posterior tarsi with
the first joint not longer than the next two. Length 8.5 mm., breadth
3.5 mm.

é. Generally narrower, with outer joints of antennae broader, and
with last ventral subtruncate at apex.

9. Generally broader and with sides of pronotum slightly depressed,
with outer joints of antennae less serrate, and with last ventral more
rounded at apex.

The color of the upper surface may vary from greenish or coppery
bronze to a very dark purplish bronze and that of the under surface
from the usual greenish to a deep bronze. Specimens are generally

immaculate but they may have from one to three well defined yellow
spots on each elytron, situated as in the spotted forms of M. fulvogut-
tata Harr. and M. drummondi Kirby.

This species in the table of Dr. Horn? would come immedi-
ately after Af. fulvoguttata Harr. It differs from this by
being generally narrower and more convex, more brilliant,
with more acute hind angles to the thorax, a more densely
punctured pronotum, and by having a subserrate ridge on the
last ventral segment near the side margin. From M. intrusa
Horn which it superficially resembles, it differs by being gen-
erally larger, by having the sides of the thorax less parallel,
and by lacking the uniformly dispersed pile on the elytra;
and from the recently described VM. piniedulis Burke, a closely
related species, it differs by being larger and more convex, by
never having the elytral maculations more than mere spots,
by having the thorax longer and with sides less parallel and
by not having the submarginal ridge of the last ventral either
so distinctly serrate or continued around the apex of the seg-
ment.

My series of fourteen specimens represents material taken
at Carrville, Trinity County, El Dorado County, Tuolumne
County, Shasta County, and Mount Wilson, Los Angeles
County, and from the yellow pine, Pinus ponderosa Dougl.,
Jeffrey pine, P. jeffreyi Vasey, digger pine, P. sabiniana
Dougl., and the big-cone spruce, Pseudotsuga macrocarpa
Mayr., the Mount Wilson specimens being captured on this
last. Besides my series, | have examined at least thirty more
specimens, chiefly in the collections of Mr. H. E. Burke and
Mr. Ralph Hopping. The species is apparently confined to
California and in Northern California and the Sierras seems
to be found only about the pines, while its more common rela-
tive, M. drummondi Kirby, has a’preference for the Douglas
fir, Pseudotsuga taxifolia Britt.

I, 1913, collected on Pinus ponderosa Doug]. by myself, in
niy own collecticn; one paratype deposited in Academy of
Natural Scienees of Philadelphia.

Chrysobothris falli n. sp.

Form and appearance nearly that of C. caurina Horn, sub-depressed,
upper surface piceous with cupreous punctate areas, head, sternum
and femora, viridocupreous, tibiae and abdomen with a greenish purple
lustre; antennae gradually more slender towards tip, third joint as long
as the next two, front flat, coarsely, somewhat cribrately punctate.
with two small callosities between eyes, and clothed with fine white,
erect pile, clypeus triangularly emarginate, with sides of emargination
rounded externally; thorax with length two-thirds of breadth, with
sides slightly divergent forwards from base, sinuate at middle, and
obliquely constricted towards anterior angles, disc moderately convex,
a rather shallow though well defined median sulcus densely punctured,
a flat but irregular callosity bounding it on either side and extending
from base to apex, two irregular callosities, one anterior and one
posterior, between this latter and sides, the surface otherwise moder-
ately densely punctured, and with a small amount of white pile at the
sides; elytra well rounded at humeri, with sides somewhat parallel from
in front to beyond the middle, thence slightly arcuate and convergent
to hind angles, disc slightly convex, the sutural costa well defined,
broader and flatter in front, narrower and cariniform posteriorly and
from middle to apex almost straight and but slightly diverging from
suture, the second costa less elevated and defined, but interrupted one-
third from base and one-third from apex, the third only evident in
median portion of elytra, the fourth feeble, all the costae joined by
certain irregular, flat, smooth and transverse areas which are more or
less aggregated or joined into transverse bands, especially just back
of base, at middle, and towards apex, the depressions all coarsely and
densely punctured, and like the elevations, with a tendency to be
formed into transverse belts as is the case one-third distant from the
base and one-third from apex; body beneath shining and quite smooth
posteriorly; prosternum slightly lobed at middle in front, quite densely
punctured, and moderately pilose; anterior femora with a broad obtuse
tooth, serrulate on outer edge; last ventral with its margin serrulate.
Length 11 mm., breadth 4.5 mm.

6. Prosternum more finely and densely punctured; anterior tibia
arcuate, rather abruptly dilated at tip, the dilatation being a lamina
arising from the posterior side about one-fourth distance from apex
and gradually arcuately widening until near apex where slightly notched,
obliquely truncated at apex; middle tibia less arcuate, gradually broader
from apical third to tip, the posterior tibia straight; last ventral seg-

ment semi-circularly emarginate, the last dorsal moderately punctate
and with a triangular emargination at tip.

@. Prosternum more coarsely and sparsely punctured; anterior tibia
moderately arcuate, gradually wider to tip, the middle less arcuate and
gradually wider to apex, the posterior straight; last ventral longer than
in male and with a shallow apical emargination; last dorsal more
grossly and closely punctate than in male and with a small apical notch;
the head, sternum and femora with more of a purplish lustre; size
slightly larger than male, length 12 mm. and breadth 5 mm

This species has the facies of C. carina Horn and is in fact
most closely related to it, though it is also sometimes confused
with C. monticola Fall. It differs from C. caurina Horn in
being more shining and in having the elytra elevations more
flattened, the sutural costa less definitely explanate towards the
apex, the clypeal emargination less acute, and in not having
the apical dilatation of the anterior tibia in the male suddenly
constricted at apex. From C. monticola Fall it can be told
by being generally smaller, more shining, by having the elytral
elevations flatter, the prosternal lobe much less distinct, the
upper margin of the eyes less close together, the dilatation of
the anterior tibia in the male not as broad nor evenly rounded
off towards the apex, and by having the space between the
suture and the sutural costae more or less checkered by alter-
nate callosities and punctured areas, a feature which it some-
times shares with C. caurina Horn and which, though super-
ficial, is quite characteristic.

A series of eighty-one specimens has been examined and
from the following localities, all in California: Independence
Lake, Nevada County, July 12-18, 1916; Donner Lake, Placer
County, July 3-8, 1916; Tahoe Tavern, Lake Tahoe, July 21,
1916, all collected by R. T. Garnett; Tuolumne Meadows,
Yosemite National Park, July 18 and 19, 1916, by G. R. Pilate,
and Forest Hill, Placer County, April, 1898, by myself. The
major portion were secured by Mr. Garnett at Donner Lake
on yellow pine, Pinus ponderosa Dougl., and at Independence
Lake on Jeffrey pine, P. jeffreyi Vasey. At the same time
were also collected one hundred and eighty specimens of typi-
cal C. caurina Horn and several typical C. monticola Fall.
This species most likely somewhat replaces C. caurina Horn

in

in the Middle and Southern Sierras and is there generally
found in company with C. monticola Fall, as is the other with
it in the more northern parts of the State.

Type male and female from Donner Lake, Placer County,
California, July 5 and 6, 1916, in my own collection; para-
types deposited in United States National Museum, Academy
of Natural Sciences of Philadelphia, and California Academy
of Sciences. The species is named in honor of my good
triend,; Mink. Ball:

Chrysobothris laricis Van Dyke.

In a small series of specimens of Chrysobothris received
from Mr. G. R. Pilate and collected by him in the Tuolumne
Meadows of the Yosemite National Park, July 11, 1916, I
found five females and one male of the above-named species.
These specimens all differ slightly from the typical phase
found in Eastern Oregon, in being more cupreous and bril-
liantly metallic, by having the transverse punctate areas of
the elytra more definitely defined, the sutural elevation more
widely explanate near the apex, and the dilated portion of
the anterior tibia in the male less broad though of the same
type. These differences, however, are simply differences in
degree and show that the species, like all of its relatives, is
variable. In this more southern area it also most likely breeds
in the lodge-pole pine, the dominant tree in the region. The
western larch does not extend into California.

Chrysobothris exesa Lec.

Within the last few years I have seen several specimens of
the above-named beetle that were taken in California, one
taken in 1912, in Imperial County, by J. C. Bridwell and the
others taken at Palm Springs, Riverside County, in April,
1917, by G. R. Pilate. These latter were taken on mesquite,
Prosopis juliflora D. C., making the sixth species of the genus
that I know of that lives on this tree, the others being: C.
octocola Lec., C. debilis Lec., C. mali Horn, C. merkeliti Horn,
and C. gemmata Lec. The last, however, has not been re-
corded from California.

The Bembicine Wasps (Hym.).
By T. D. A. CocKERELL, University of Colorado, Boulder, Colo.

Entomologists are greatly indebted to Professor J. B. Parker
for his exhaustive study of the Bembicine wasps of North
America, published in Proceedings, United States National
Museum, Vol. 52, pp. 1-155 (1917). The work represents
the labor of years, and includes full descriptions, tables of
genera and species, and excellent illustrations. Strangely
enough, for reasons which it is hard to comprehend, the author
has failed to complete his elaborate treatment by giving ade-
quate particulars concerning the localities of the new species.
After so much labor, why was that of copying the labels of
the specimens described too great to be undertaken? Why
was it considered,—if the matter was considered,—that in a
State containing six different life zones the type locality of
a species was a matter of utter indifference? There is no
good reason why entomologists should not conform to the
rules of procedure in describing new species, which are well
established in botany, ornithology and other kindred sciences.
It is just as easy to do these things properly as any other
way, and it seems a pity that entomological writings, so ad-
mirable in nearly every respect, should fail where failure
could so readily be avoided. There are two orders of insects,
the Orthoptera and Odonata, in which the treatment in practi-
cally all recent American papers is above reproach. These
orders have been fortunate in being studied by men who were
well acquainted with the best methods employed in other de-
partments of zoology. Why should not Lepidopterists, Hy-
menopterists and Coleopterists take note?

In the particular case under discussion I have thought it
useful to ascertain the type localities of many of the new
species and publish the data. For the particulars given I am
greatly indebted to Mr. S. A. Rohwer and Professor S. J.
Hunter.

A new Genus of Cyrtidae from South America (Dip.).*

By FRANK R. CoLg, Scientific Assistant, United States
Bureau of Entomology.

In preparing a monograph of the Cyrtidae of North Amer-
ica, the writer has had access to the collection in the National
Museum. In this collection of Cyrtidae there are a few speci-
mens frcm Chile, South America, collected by C. E. Reed.
One specimen labeled Lasia dimidiata seemed to be so entirely
different in general appearance from any known species of
that genus that I took the trouble to examine it more closely.
This specimen is of an undescribed genus, quite far from Lasia,
and belongs in another subfamily—the Oncodinae. The ab-
domen has evidently been broken off and is glued on to the
thorax at an impossible angle. One of the front legs is broken
off in the middle of the femur and the last four joints of the
tarsi are broken off from the other front leg.

VILLALUS new genus.

Head hemispherical and composed almost entirely of the
eves. Eyes touching from vertex to antennae and from small
space at antennae to the tiny mouth parts. The mouth parts
are rudimentary and the facial triangle much reduced and on
the under side of the head. There is no proboscis. The eyes
are thickly covered with very short pile. Antennae small and
apparently two-jointed (see Fig. 3), the first joint being sunken
in the head; second joint cylindrical and not much longer than
broad ; the third joint radish-shaped and with a slender style
which is enlarged slightly at the tip and ends in a microscopic
bristle. Ocellar tubercle rather small, with three ocelli, form-
ing an equilateral triangle (see Fig. 4). Odcciput slightly
swollen and with short hairs.

Thorax large and swollen in appearance with rather short
recumbent hair. Upper pleurae swollen and covered with
hair. Humeral callosities quite large but widely separated.
Post-alar callosities of medium size. Scutellum rounded and
about as long proportionately as in Oncodes. Legs including

coxae with thick short hairs, legs of normal size and struc-
ture, the ungues rather short. (See Fig. 5.)

Abdomen quite large in proportion to body, the venter
probably flat in life, or slightly convex (in this specimen it
has been drawn in when the body dried). The abdomen is
composed of six segments.

Wings rather long and narrow and of the general shape
of the wing of Eulonchus sp. Squamae large and of rather
thick membrane as in Oncodes. Alula not projecting. Vena-
tion quite different from any known genus of this family.
The auxiliary, first and second veins are rather long and
heavier than the other veins. There is a long cell above the
discal cell, the outer first basal cell, present in some other
genera. The third vein is not forked and ends in the apex of
the wing. There are four posterior cells, all widely open.
Second basal ceil much longer than the first. Anal cell long
and narrowed in the margin. Anal vein does not quite reach
the margin of the wing. The membrane of the costal, sub-
costal, marginal, submarginal, outer first basal and first pos-
terior cells covered quite thickly with short hairs.

Villalus chilensis new species.

Head and eyes black. The reddish-brown antennae are small, the
first apparent joint cylindrical, the second joint (actually the third)
radish-shaped and with a rather long slender style which expands a
little near the tip and ends in a thin microscopic bristle.

Thorax brownish-yellow with rather thick short pile of a dark yellow
color. Scutellum, humeral and post-alar callosities brownish-yellow.
Pectus blackish. Halteres brownish yellow. Legs, including coxae,
pale yellow, ungues black.

Abdomen brownish-yellow with a reddish tinge, and clothed with
rather short reclinate yellow pile. Venter (probably somewhat dis-
colored) a paler yellow, with dark spots on second, third and fourth
segments. Genitalia very inconspicuous.

Wings rather long, the anterior half clouded with brown, darker near
the costa. Squamae brownish hyaline, margined with black and with yel-
low hairs on the surface. Costa and veins blackish-brown. Membrane of
the costal, subcostal, marginal, submarginal, outer first basal and first
posterior cells covered with very fine short hairs of brownish color.
Auxiliary, first and second veins long and heavy. Cross-veins separat-
ing first basal cell from marginal, submarginal and outer first basal

64 ENTOMOLOGICAL NEWS. [ Feb., 18

cells quite heavy. Third vein unforked and ending in the wing tip.
Second basal cell almost twice the length of first basal and about as
long as discal cell. Supernumerary cross-vein at base of first posterior
cell parallel with the short vein between the discal and second posterior
cells. All of the posterior cells are widely open. There are only two
veins emerging from the discal cell, the third branch, found in Eulon-
chus, Lasta and a few others having disappeared.

Type.—United States National Museum, No. 21074. One
specimen. Habitat——Chile.

The genus Holops Phil. is probably the nearest to Villalus.
Holops inants Phil. is yellow with yellow pile and has the
anterior margin and apex of the wings infuscated. Philippi

in his brief description mentioned that the small mouth open-

ing was triangular. He stated that he could see no proboscis
(as in H. cyaneus), but thought it might possibly be strongly
retracted. No mention is made of the wing venation. The
head of Villalus is like that of Holops and the antennae of like
structure and similarly placed. If the figure of H. cyaneus
given by Philippi can be relied on, the venation is quite dif-
ferent from Villalus. Verrall in “British Diptera,” Vol. V,
p. 451, has a figure of the wing of Holops nigrapex Big. which
is like that shown by Philippi in his “Aufzahlung der chileni-
schen Dipteren.” In both of these figures the third vein is
forked and the veins posterior to this do not reach the wing
margin. Also the anal cell is closed some distance from the
margin and the discal cell has a third vein emerging from it,
missing in Villalus. This is the only Cyrtid that I know of
which has short hairs on the wing membrane.

Verrall in “British Diptera” stated that Megalybus gave a
clue to the venation of Oncodes and Acrocera and was a type
intermediate between Eulonchus and Astomella. This genus
Villalus has a venation very nearly approaching that of Mega-
lybus. We see in this form a modification of the more com-
plex venation of Lasia, Eulonchus and Pteropexus, and a
suggestion of the still more simplified venation of Oncodes.

Material Desired (Coleoptera).
Dr. W. D. Pierce, Bureau of Entomology, Washington, D. C., desires

A Correction Concerning Labia annulata and Labia dorsalis. (Der-
maptera; Labiidae.)

We wish to draw attention to an error recently made by us, Trans.
Am. Ent, Soc., XLIII, p. 318. We have there given Labia dorsalis
(Burmeister) as a synonym of Labia annulata (Fabricius) and have
supplemented this by stating that no differences between the de-
scriptions of these species could be found. Asa matter of fact annulata
and dorsalis are widely distinct species as understood by us, belong-
ing to different sections of the genus as was pointed out elsewhere in
that same paper, and when the group has been thoroughly studied
will probably be found to require even generic separation.

This confusing mistake was made through including in the rough
manuscript an earlier and unverified incorrect note to this effect,
which was in consequence incorporated, but inexcusably overlooked in
both the reading of the finished manuscript and the proof—MorcGan
Hesarp, Philadelphia, Pa.

Argynnis apacheana, a New Name (Lepid.).
By Henry SKINNER.

___ I propose the name afacheana for the species of Argynnis

described and figured by Mr. W. H. Edwards in Volume I
of his Butterflies of North America, plate IV of Argynnis,
figures I, 2, ¢, 3, 4, ?, under the name nokomis.

What he originally described as nokomis in the Proceedings
of The Academy of Natural Sciences of Philadelphia for the
year 1862, page 221, is a different species. The type was a
male and he gave as the locality, “Rocky Mountains, and
Mountains of California.” He also says, “This is much the
largest of the Pacific species, equalling the largest specimens
of Cybele. In color it most resembles Aphrodite. The female
I have not seen.” This is the same species which he subse-
quently described under the name nitacris, in the Transactions
of the American Entomological Society, 1874, Volume XV.
The type of nitocris was “one male taken at White Mountains,
Arizona, by Lieut. Henshaw of the exploring Expedition
under Lieut. Wheeler, August, 1873.”

In volume one of his Butterflies of North America, Mr.
Edwards says in regard to nokemis, “The original specimen
from which the description of the species was drawn was re-
ceived by me in 1862, through the Smithsonian, and was
labelled ‘Bitter Root Mountains’. . . . Until the present
year (1872) it has been an unique in my collection and, so far
as I know, not found in any other.” Recently Mr. R. C. Will-
iams, Jr., searched the Edwards-Holland collection in Pitts-
burgh for this type but was unable to find it. Nokomis was
twice figured by Mr. Edwards for this Volume I, the upper and
under sides of the male being given, and drawn by D. Wiest,
but this plate was not published and the American Entomo-
logical Society, which issued the volume, still possesses the
withdrawn plates. Mr. Edwards, having received five males
and two females, of what I call apacheana, brought from
Arizona by the Exploring Expedition under Lieutenant
Wheeler, in 1871, beautifully figured both sexes, the drawings

68 ENTOMOLOGICAL NEWS. [Feb.,’18

in the plate actually published having been made by Mrs.
Peart.

Mr. B. Neumoegen received quite a number of both sexes of
apacheana and the specimens in collections are from this ma-
terial. Mr. Jacob Doll informed me that all these specimens
were shipped from Kanab, Utah, but he did not know the ex-
act locality where they were taken. There can be no question
but that the original description of nokomis applies to what
we know as nitocris and therefore nitocris becomes a synonym
of nokomis.

If anyone possesses specimens of apacheane, with accurate
data, it would be very useful to have the localities and dates
of capture published. At present 1 am not prepared to say
anything about the specific value of the two names, but I have
not seen any maculation characters that show intergradation.

Variation in Labial Characters in the Nymph of
Gomphus spicatus (Odonata).

By Atice L. Strout, Buffalo, New York..

In the identification of a collection of Gomphus nymphs
sent to the Limnological Laboratory of Cornell University,
slight variations were noticed in the minute characters of labia
whose general form seemed identical. As the labial char-
acters are those most depended upon for the separation of
species, it was necessary to study the variation in one species
before using the minute characters to differentiate between
species. The material for this study was one hundred and
ten exuviae of nymphs of Gomphus spicatus collected by Dr.
Needham at one time and place.

The labial characters used for the separation of species are
as follows: The shape of the median lobe, the presence or
absence of a median tooth on this lobe, the form of the median
tooth when present, the number and shape of the teeth on the
inner margin of the lateral lobes.

In the following study, variations in the above points were
noted. I mounted one hundred and ten labia from the above

70 ENTOMOLOGICAL NEWS. [Feb., 718

mentioned material. The most typical form was that shown
in Fig. 1. The variations occurred in various characters.

The end hook showed four tyes: Type I (Fig. 2) was long
with the first tooth indistinctly separated from it. There were
fifty-five specimens of this type.

Type II (Fig. 3) was short with the first tooth indistinctly
separated from it. There were forty-eight specimens of this
tvpe.

Type III (Fig. 4) was long with the first tooth distinctly
separated from it. There were five specimens of this type.

Type IV (Fig. 5) was blunt at the end and occurred six
times.

The number of teeth on the lateral lobe varied from four
to ten. The most usual number was six or seven. The varia-
tions toward few or many were both rare as is shown by the
data:

Left lobe Right lobe
Number of teeth An 5,0, 7, 8710, 10 4.5, 6, 7,98, oa
Frequency 1, 8, 40, 44,16, 0, I 0, 7,39, 44,18, I, I

The median lobe varied in shape from nearly straight to
very convex (Figs. 6, 7 and 8). The tooth on the front mar-
gin was single or double. Each of these forms varied from
rudimentary to pointed. In some cases it was absent. The
occurrences were as follows: Median tooth absent in eight
cases, single and rudimentary fifty-one cases, single and pointed
thirty cases, bifid and rudimentary five cases, bifid and pointed
nine cases.

These variations show that the detailed characters which
have been used to differentiate between species cannot be
used as absolute criteria, but must be considered with general
shape and size of the labia, which remain fairly constant in
one species.

Professor F. L. Washburn Ceases to Be State Entomologist.

In order to be enabled to devote all of his time to closely allied
economic work in the Agricultural Department of the University of
Minnesota, Professor F. L. Washburn, for fifteen years State Entomol-
ogist, has asked and obtained the consent of the Board of Regents of
the University to drop the State Entomologist work, with its attendant
police and quarantine duties, this change to be effective February 6th,
1918.

PHILADELPHIA, Pa., FEBRUARY, I918.

Entomology at the Convocation Week Meetings.

As announced in the News for December last (page 469),
we shall not print a list of the papers bearing on entomology
presented at the meetings of various societies at Pittsburgh
and at Minneapolis, between December 27, 1917, and January
2, 1918. In spite of the special conditions induced by the
war and the extremely cold weather upon railroad trans-
portation, and of the deterrent letter of the President of the
American Association for the Advancement of Science (pub-
lished in Science for December 28 and elsewhere), the attend-
ance seems to have been fair. We are informed that 50 to
60 persons were present at the meetings of the Entomological
Society, 25 to 50 at those of the Ecological Society, and 20
to 200 at those of the Naturalists. The total number of papers
of entomological bearing listed on the printed programs, with
some additions of which we have been informed, was, at
Pittsburgh, 96, or, if we add those forming parts of the
Paleontological Society’s symposium on “Problems in History
of Faunal and Floral Relationships in the Antillean-Isthmian
Region and their Bearing on Biologic Relationships of North
and South America” (8 titles) and those constituting the
Naturalists’ symposium on “Factors of Organic Evolution”
(6 titles),—110, and 9 at the Zoologists’ meeting at Minneap-
olis—a grand total of 119, in comparison with 139 at New
York in the preceding year (see the NEws for February, 1917,
page 88).

The above-quoted total of 96 was made up of 24 papers
from the program of the Entomological Society of America,
48 from that of the American Association of Economic Ento-
mologists with 7 from its Apicultural and 4 from its Horti-
cultural Inspection Sections, 3 from the Ecological Society of
America, 1 from the American Phytopathological Society,

7 from the American Society of Naturalists and 2 from Sec-
Bon kcA. Aaa:

The subject of the annual address to the Entomological
Society was “The Biological Aspects of the War” by Prof.
Vernon ‘ellosg, that of the President (Prot. Keo
Cooley) of the Economic Entomologists, “Economic Entomol-
ogy in the Service of the Nation.” Dr. L. O. Howard was
scheduled to take part in Section F’s symposium on “Contri-
butions of Zoology to Human Welfare.” Other topics of
more than ordinary interest to be treated were: “The Bio-
climatic Law of Latitude, Longitude and Altitude, as applied
to Entomological Research and Practice,” by A. D. Hopkins;
“Distribution of the Maritime Diptera of Eastern North
America,’ by C. W. Johnson; “Reminiscences of my early
work upon the Diptera,” by S. W. Williston; “Insects and
Camp Sanitation,” by E. P. Felt; a general discussion on “How
can the Entomologist assist in Increasing Food Production?”
and moving pictures of Gipsy Moth Work in New England,
conducted by the U. S. Bureau of Entomology. Doubtless
some of the papers on the geographical distribution of plants
at the joint session of the Ecological and Botanical Societies
will be helpful to entomologists. As in 1916, the Zoologists,
Anatomists and Ecologists distributed, some days before their
meetings. printed abstracts of the papers to be presented at
their sessions.

Benjamin Dann Walsh.

A brief account of the life of Benjamin Dann Walsh, whose like-
ness appears on the cover of the News for 1918, was published in this
journal, volume V, pages 269-270, November, 1894, accompanied by a
different portrait.

Emergency Entomological Service.
Numbers 8 and 9 of these mimeographed Reports issued by the
United States Department of Agriculture appeared under the dates of
November 6 and December 3, 1917, respectively. No. 8 is supplementary

Vol. xxix | ENTOMOLOGICAL NEWS. 73

to No. 7 (noted in the News for December, 1917, page 470), as it con-
tains reports received too late for inclusion in the latter; additional
data on the cotton boll weevil in South Carolina, Georgia, Tennessee
and Oklahoma are recorded; Euphoria inda is noted as injuring cotton
bolls in Tennessee for the first time; injuries to apples, due to the
codling moth are widespread, as in New York, Oregon, Tennessee and
Utah; corn-stalk borers and peach-twig borers in Arizona, fall migrant
aphids in Idaho, apple and thorn skeletonizer (Hemerophila pariana)
in New York, Crioceris asparagi for the first time in Oregon, the
strawberry root louse in Tennessee and grasshoppers (4 spp.) in Utah
receive special mention.

No. 9 contains a report of the Federal Horticultural Board on two
additional outbreaks of the pink boll-worm in Texas, reported to the
Department early in November. The more serious of these is at Trinity
Bay, north of Galveston, “the total infested area involved being up-
wards of 5,000 acres”: “clean-up operations are being pushed with the
utmost speed.” Results of a recent trip by Mr. Busck to study the
status of this insect in Mexican cotton fields are given.

“As the sesson of field activities for 1917 nears its end, the outlook
as regards the chief insect pests of cereal and forage crops in general
is encouraging. With the exception’ of white grubs and grasshoppers,
none of the more dangerous enemies seems to be present in sufficient
numbers to warrant apprehension. Of course, this does not mean that
a great outbreak of chinch bug, Hessian fly, army worm, or green bug
cannot occur during the growing season of 1918. Nevertheless, field
conditions at present indicate no such probability.”

The sweet potato weevil (Cyclas formicarius Fabr.), “the most im-
portant pest of the year,” was found in November for the first time in
(coastal parts of) Georgia and Mississippi, as well a im Tennessee;
data on the present known distribution of this species are given. Plans
for extension work in bee-keeping west of the Appalachians are out-
lined. We shall reprint elsewhere in the News a very interesting state-
ment concerning Jcerya control at New Orleans. There are reports
trom fourteen States and from Porto Rico, dealing with many
insects of economic importance.

Report No. 10, for January 5, 1918, contains some little additional
information on the pink boll-worm in Texas and Mexico. The Secre-
tary of Agriculture has prohibited the importation of any variety of
sweet potato or yam (Ipomoea batatas and Dioscorea spp.) from all
foreign countries and from Hawaii and Porto Rico into any part of
the United States, from January 1, 1918; this is in relation to the
spread of the sweet potato weevil, for which additional localities in
Mississippi are reported. The report from California, occupying
nearly three pages, consists of a statement by Mr. George P. Gray on
the consumption and cost of the economic poisons employed against

74 ENTOMOLOGICAL NEWS. [Feb., 718

insects, fungi and rodents in that State. Mr. E. N. Cory, of the
Maryland Experiment Station, proposes the installation of a large
rotary dryer at each army cantonment for the drying of horse manure
and the distribution of the dried article “through the help of the
National Fertilizer Association at a cost plus percentage basis, thus
relieving the soldiers and civilians of the menace of flies and provid-
ing for the farmer a source of fertilizer in the time of scarcity. More-
over, the number of cars required to handle this material will be
greatly reduced from the number required under the old plan to handle
daily the fresh manure produced at each camp.”

Changes of Address.

C. W. Howard, Associate Professor of Entomology, University of
Minnesota, will remove to Canton, China. Address: care of Canton
Christian College, Hongkong, China.

H. H. Knight, formerly of Ithaca, New York, and F. R. Cole, of
Hood River, Oregon, have entered military service.

Dr. J. Chester Bradley, of Cornell University, has accepted an assist-
ant professorship of entomology at the University of California for
19018.

A New House Spider (Aran.).

One day in October, 1914, I was in a restaurant in Boston when
a spider walked over the table and was caught. It looked different
from any native species and I put it aside for further examination.
In December, 1915, I stopped for a meal in the railroad restaurant
at Cleveland, Ohio, and there a spider came onto the table and was
caught. It turned out to be the other sex of the species found in
Boston. In May, 1917, a friend who has a tannery in Danvers, Massa-
chusetts, sent me another of the same species out of a bale of hides
from Africa. I then consulted Mr. Banks and he was at once re-
minded of Thanatus coloradensis Keyserling and brought out a bottle
of this species from Claremont, California, which on comparison
proved to be the same as the eastern spiders. So it appears that we
have here a western spider that takes readily to life about houses and
is spreading across the country—J. H. Emerton, Boston, Mass.

Interrelations of Different Species of Insects (Hom., Col., Hym.).

All things considered, the progress of Icerya control at New Orleans
during the summer and fall [of 1917] has not been entirely satisfactory.
Apparently several agents have retarded the successful propagation of
the V’edalia. Chief among them must be mentioned the Argentine ant.
This ant undoubtedly aids in a very material increase of the Jcerya.
In the fall of the year they reach their maximum numbers and these
hordes so effectively patrol and guard the scale infestations that the

Vol. xxix] ENTOMOLOGICAI, NEWS. 75

adult lady beetles are not allowed a moment’s peace. By means of a
natural protection the Vedalia larvae are not molested by the ants, nor
are the stationary pupae, but the adults seem to lack this protective
quality and many of them are actually killed and devoured by the ants.
The extremely high temperatures accompanied by relatively high
humidity during the summer exerted a very depressing effect upon the
propagation of the Vedalia. They died off in millions so ... that they
could not entirely hold the scale in check. For about a month, from
mid-September to the middle of October, the weather was ideal for
their propagation and they did very nicely, then it turned much too
cool and for the past six weeks [to Nov. 27] they have done very
little outdoors. . . . . . . . Very interesting results have been
obtained through the very effective control of the Argentine ant
in and around the hothouse used for the propagation of the Vedalia.
Until the ants were controlled no difficulties were encountered in
obtaining heavy infestations of the Jcerya on three large Pittosporum
bushes which were planted in the hothouse and caged for Vedalia
propagation. Since the control of the ant, however, the Jcerya is not
doing nearly so well. The honeydew which was assiduously gathered
by the ants for food now remains attached to the scales and as it con-
tinues to be excreted it drops down forming threads which “candy”
in the dry atmosphere. So much of this honey-dew is in evidence that
the plants have taken on a snowy appearance.—C. L. Marvatt in Re-
port No. 9, Emergency Ent. Service, U. S. Dept. Agr., Dec. 3, 1917.

Maternal Care in Dinocoris tripterus Fab. (Hemiptera).
Early in February, 1017, in conversation with Ralph Ballin, |
a high school youth of this city, I learned that he had found on a
banana, and still had in his care, a mother bug and her brood. I
urged him to make what observations he could and later he presented
me with the mother and her fifteen offspring. The adults and
nymphs were identified by Mr. E. H. Gibson as Dinocoris tripterus
Fab. Mr. Gibson writes that, so far as he has been able to learn,
members of this genus occur only in Central and South America, and
that the nymphs are in the second instar.

Since there was some doubt in the mind of Fabre as to the ac-
curacy of the observations on the maternal instinct in Hemiptera,
and as Kirkaldy has unearthed much evidence (Entomologist, 36:
113-120, 1903) to show the unfairness of Fabre, I quote the following
from a letter from Ralph Ballin in reply to certain questions, with
a figure made from a rough sketch by this youthful observer:

“Early in February I found the group, mother, empty egg shells and
young, on part of the banana nearest the stalk; this was concealed
by other bananas. The young were already hatched when I found

76 ENTOMOLOGICAL NEWS. [Feb., 718

the group; they were ranged around the empty egg shells. These
shells were all together, like the cells of a honey comb, and one end
of each had been broken by the young as it emerged.

“Close to the egg shells and the young bugs was the mother. The
entire group for the most part remained motionless and apparently
lifeless. She neither brooded over the young, nor did the young
crawl over the mother’s body. Occasionally, however, one of the
young would move and in so doing would disturb the others; except
for this they remained motionless. The mother remained in the same
position almost all the time: only a few times did she slightly shift her
position to one side or the other.”

With food abundant at hand, there was little occasion for much
activity and still I hardly think it was entirely due to this cause that
the mother remained with the brood into the second instar. While
it is possible that the whole phenomenon is accidental, there is some
probability that this is an actual case of maternal solicitude in this
insect.

Further observations will have to decide whether the mother’s close
proximity to her brood is one of maternal solicitude or only one of
physical economy.—Puit Rau, St. Louis, Missouri.

Doings of Societies.

Entomological Society of France.

The treasurer’s report of the Entomological Society of France for
1916 shows receipts to the amount of 27,670 francs and expenditures
(including investments) of 25,400 francs. The capital of the Society
December 31, 1916, was 139,038 francs. (Bull. Soc. Ent. France, 1917,
No. 7). The Society awarded the Dollfuss prize for 1916 of 300 francs
to Prof. Auguste Lameere, of the University of Brussels, for his works
on Prionidae, and the Constant prize of 1916 of 500 francs to J. Sainte-
Claire Deville for his Catalogue critique des Coléoptcres de la Corse
(1914).

Entomological Section, Academy of Natural Sciences of Phila-
delphia.

Meeting of November 22, 1917, Director Philip Laurent presiding
and eight persons present. Henry W. Fowler was elected a contributor.

Mr. J. A. G. Rehn made a communication on the physiography of sev-
eral collecting regions of southern Arizona, illustrated by lantern slides.

Diptera.—Dr. Skinner read an abstract of an article by McDunnell
& Eastwood, relative to the overwintering of the house fly. Dr. Cal-
vert exhibited larvae of Bibionidae (identified by comparison with fig.
225, p. 476, of Vol. vi, Cambridge Nat. Hist.), some of a very great num-
ber found near Media, Pennsylvania, November 11, 1917, by Dr. J. P.
Moore. The larvae were observed in an area of about two square feet,
at a depth of 2-3 inches, in soil near a peach tree, on which soil goat
manure, mingled with decaying corn stalks and forest leaves, had been
placed in the preceding winter. He referred to similar observations in
the work cited, in Packard’s “Guide to the Study of Insects,” and in
Kellogg’s “American Insects.”

Lepidoptera.—Mr. Laurent presented two specimens of Aetha-
loptera anticaria Walker from Chestnut Hill, Pennsylvania, and blown
larvae of three species of Datana. He also exhibited an interesting ab-
normal male of Samia cecropia, also a female cecropia seven and one-—
eighth inches in expanse. The speaker stated that this was the largest

8e ENTOMOLOGICAL NEWS. [Feb., 718

specimen, by a quarter of an inch, out of many hundred that he had
bred. Dr. Skinner spoke about his work on the genitalia of Argynnis.

Orthoptera.—Mr. Rehn commented on, and gave some illustra-
tions of the genitalic characters of several Orthoptera, showing that the
value of certain characters is not constant in the various groups or
families—E. T. Cresson, Jr., Recorder.

OBITUARY NOTES.

ANTOINE GROUVELLE, specialist on the Clavicorn Coleop-
tera, died at Neuilly-sur-Seine, France, June 9, 1917, aged
74 years. He became a member of the Entomological Society
of France in 1870, served as President in 1891 and 1897 and
was elected an honorary member in 1911. Until his retire-
ment, in 1907, he was Director of the State Tobacco Factory.
His papers number more than 150, one of the latest having
appeared in the Bulletin of the French Society for March 28,
1917. His collection of Coleoptera, said to be very large and
valuable, was bequeathed to the Paris Museum. (Obituary
notices in Bull. Soc. Ent., Fr., 1977, pp. 181-2, and Ent. Mo.
Mag:, August,’ 1917.)

The deaths of Commandant PrerrE XamBeEu, “author of
numerous works of compilation on the larvae of Coleoptera,”
at Ria, Pyrénées-Orientales, France, on June 9, 1917, aged 80
years; of Dr. E. A. Gotpr, formerly director of the museum
at Para, Brazil, subsequently named the Museu Goldi in his
henor, at Berne, Switzerland, July 5, 1917; and of Dr. Max
STaNpFuss, of Zurich, well known for his experimental re-
searches on the variability of Lepidoptera (date of death not
given), are announced in the Bulletins of the Fntomological
Society of France, 1917, Nos. 12 and 14.

Among the deaths of entomologists during 1917, as a re-
sult of the war, we note with sorrow and sympathy for his
father, that of REGINA, JAMES CHAMPION, Lieutenant, Scots
Guards, July 18. 1917, at the age of 22. He had already pub-
lished four papers on insects. (Ent. Mo. Mag., London,
Sept., 1917.)

2 The Celebrated Original Dust and Pest-Proof

METAL CABINETS

FOR SCHMITT BOXES

These cabinets have a specially constructed groove»or trough around the front,
lined witha material of our own design, which is adjustable to the pressure of the front
cover. The cover, when in place, is made fast by spring wire locks or clasps, causing a
constant pressure on the lining in the groove.. The cabinet, in addition to being abso-
lutely dust, moth and dermestes proof, is impervious to fire, smoke, water and atmos-
pheric changes. Obviously, these cabinets are far superior to any constructed o: non-
metallic material. ; ;

' The interior is made of metal, with upright partition in center. On the sides

are metal supports to hold 28 boxes. The regular size is 424 in. high, 13 in. deep, 18%

in. wide, inside dimensions; usually enameled green outside. For details of Dr. Skin-
ners: construction of this cabinet, see Entomological News, Vol. XY, page 177.

METAL INSECT BOX has.all the essential merits of the cabinet, having a

:

groove, clasps, ete. Bottom inside lined with cork; the outside enameled any color
‘desired. The regular dimensions, outside, are 9x 13x 2h in. deep, but can be furnished
any size.

WOOD INSECT BOX.—We do not assert that this wooden box has all the quali-
ties of the metal box, especially in regard to safety from smoke, fire, water and damp-
ness, but the chemically prepared material fastened tothe under edge of the lid makes
@ box, we think, superior to any other wood insect box. The bottom is cork lined.

_ Outside varnished. For catalogue and prices inquire of
