No. 3. — New Neuropteroid Insects.
BY NATHAN BANKS.

IN the course of identifying the Neuropteroid insects in the Museum
numerous new species were found; some of these are herewith de-
scribed. In several cases Dr. Hagen had given manuscript names,
and in a few cases these have been published, as the South American
species in the appendix to his Synopsis of the Neuroptera of North
America. Wherever possible I have retained his manuscript name.

Pale yellowish red, thoracic notum hardly darker, antennae brownish, wings
almost hyaline, faintly infuscate, stigma with dark basal spot; veins pale.
Head broad, with few erect bristly hairs; antennae minutely hairy, about two

DYPSOCUS PARVULUS, sp. nov.

TYPE.— M. C. Z. 10,794. Straits Settlements: Singapore (C. F.
Baker).

In general appearance similar to D. apicatus and D. coleoptratus; differs
from them in having the antennae very slender throughout. The head is
flattened, with short, dense hair, the antennae are pale brown, minutely hairy.
The fore wings have a broad dark stripe over most of surface, leaving the apical
costal region clear, but a dark band across the tip of the stigma, the posterior
margin is scarcely hyaline except in the areola postica and a little before it.

314 BULLETIN: MUSEUM or COMPARATIVE ZOOLOGY.

The radial sector and median are connected by a cross-vein, the apical branches
are not short and crowded as in the other species of the genus, but like Caecilius,
the areola postica is very small and short, and the stigma of moderate length,
rounded behind.

Length, to tip of wings 3 mm.

I place parculus in this genus on account of the separation of radial
sector and median vein and the structure of the head, but the rest of
the venation and the antennae are like Caecilius. The D. dolobratus
Hagen is a Caecilius very close to C. himaylamis Enderl., besides the
types I have dolobratus from Singapore and Island of Penang.

CALOPSOCUS IRIDESCENS, sp. nov.
TYPE.— M. C. Z. 10,783. Borneo: Sandakan (C. F. Baker).

Vertex, seen from in front, broadly, but not deeply, concave (not narrowly
incised as in C. infelix). Wings proportionally longer than in C. infelix, and
densely reticulately veined, even from before the middle to near the outer edge.

ISOGENUS HASTATUS, Sp. nOV.

TYPE.— M. C. Z. 10,820. N. C.: Andrews, middle of May (F.
Sherman). N. H.: White Mts. (E. P. Austin).

In many ways similar to I. frontalis but darker, especially the wings. The
head has the posterior yellow spot continued into a hastate mark between the
posterior ocelli, a pale spot each side on lower face. The seventh ventral
segment is slightly convex in the middle and there orange in color, the following
segments have apical margins narrowly orange, and the basal segments are
pale on tips. The ocelli form a triangle nearly equilateral, and the wings have
no cross-vein from near tip of radial sector to radius, otherwise much as in 7.
frontalis.

Expanse 36 mm.

Although differing in venation the genital characters are so similar
to those of Isogenus that I include it in that genus as Dr. Hagen had
done in the collection.

Black, with yellowish head and prothorax. In general closely similar to
P. mexicana, but the head has a distinct black spot above each antenna, and
behind the eye is a black trifid mark back of the upper part of eye, instead of
the much larger bifid mark back of entire eye in P. mexicana. The wings are
infumate much as in P. americana, not as black as P. mexicana,' the venation
about as in P. mexicana, the basal cross-vein between the cubitus and first
anal ends on cross-vein much beyond origin of radial sector, the first cross-

Norway (S. I. Smith). Mass.: Milford, 8 June. N. J.: Lafayette,
26 May.

Deep black, some specimens showing the wings paler beyond the basal third.
Structure in general similar to S. infumata and S. concava but the ventral plate
of male is nearly as long as broad, with subparallel sides, and a broadly rounded
tip, usually covering all the other parts from below; the last dorsal segment of
male is broadly excavate below, not so deeply nor so narrowly as in the other

European species. Last dorsal segment of male seen from above is rather
long, slightly narrowed and nearly truncate at tip, being only a little indented
in middle, from behind it is shallowly, broadly emarginate and shows below
a recurved spear-shaped plate with a depressed middle area and appressed to
the ventral plate.

This has been considered the European S. fuliginosa, but the male
genitalia are of very different structure.

SlALIS ROTUNDA, sp. UOV.

(seen from the side) it is tapering; the two lower processes are dark, rather
stout, and with a tooth or enlargement near inner base. In the female the
last ventral segment has a large, apical yellow spot, and a median ridge; the
ovipositor reaches to tip of wings.

MYRMELEONIDAE .

CYMOTHALES HERMOSA, sp. nov.

TYPE.— M. C. Z. 10,565. N. Angola: Dalla Tando, 29 November
(Le Moult); two specimens.

Wings marked in general as in C. spedosa and eccentros; only very small
stigmal spot as in eccentros; apical band broken up more by spots than in
eccentros. The upper part of the middle band is broader in front than behind
(in eccentros broader behind). Head pale, black between and above antennae,
antennae pale, dark on extreme base, vertex with a hump each side which has
a slightly bilobed summit. Pronotum black, a pale line each side, and behind
are two oblique lines on each side; thorax blackish, with a pale line each side;
pleura dark. Abdomen pale with two black stripes above; legs pale, femur
of front legs black except at base and tip, with dense black hair, and longer
erect black bristles, hind femora also with black bristles. Front tarsus has
basal joint longer than the fifth, the spurs a trifle longer than first and second
joints together. In fore wing four to six cross-veins before any are crossed,
but the radial sector arises farther out at the middle band; nine or more
branches to radial sector; in hind wing one cross- vein before radial sector.

Length fore wing 30 to 34 mm., hind wing, 35 to 38 mm.

This belongs to the section or subgenus Mironius.

CHAETOLEON, gen. nov.

Differs from Brachynemurus, Austroleon, and allied genera in having erect
enlarged bristles upon the mesonotum in front, also in that on the fore wing the
second and third anal veins are united for a short distance, the second anal,
however, does not approximate the first anal vein in its basal part (as in the
Formicaleonini). The antennae are long and slender, with much enlarged tip.
Legs slender, with very long bristles, the tarsus shorter than the tibia, the first
tarsal joint a little longer than the second, spurs equal, two tarsal joints.
Wings moderately slender, in fore wings three cross-veins before radial sector,
in hind wings two such cross- veins; radial sector in fore wings arises much
before the fork of the cubitus.

TYPE. — - Myrmeleon pumilis Burmeister.
Brachynemurus pusillus Currie also belongs here.

PUREN.

I include in this genus Myrmeleon inscriptus Hagen. It differs from
Psammoleon in having the basal joint of the tarsus much longer than

BANKS: NEW NEUROPTEROID INSECTS. 329

the second joint, and the spurs elongated and curved only near tip.
In P. inscriptus, as in the genotype, the costal area of the fore wing is
biareolate; in P. connexus this area has but one series of cells. Both
differ from the type of Puren in having more (6 or 7) cross-veins before
the radial sector in the fore wing.

PUREN CONNEXUS, sp. nov.

TYPE.— M. C. Z. 10,848. Calif.: San Jacinto Mts., 25 June (P.
Grinnell).

Head pale, a black interantennal mark, .two transverse rows of black spots
across vertex; pronotum black, a narrow median pale line, and on each side
a spot in front and a line behind; mesonotum with pale spot and stripe each
side. Abdomen black. Legs mostly black, hind tibia pale on outer basal half,
femora and tibia with black bristles, some black and many white hairs; basal
joint of tarsus twice as long as the second, spurs equal almost two joints, but
little curved except near tip, the claws hardly one half as long as the spurs.
Wings hyaline; veins pale, marked with black, mostly in long streaks. As in
P. inscriptus there is in the fore wing a prominent flexuous dark line, formed
by connecting the oblique mark at end of anal with that up from end of cubitus,
this line is not as deeply incurved as in P. inscriptus. In both fore wings there
is a strong vein from forking of cubitus obliquely upward and backward to the
median, possibly this is abnormal. The wings are narrower than in P. in-
scriptus, and the costal area has but a single series of cells.

Expanse 54 mm.

EREMOLEON NIGRIBASIS, sp. nov.

DlMARES HAGENI, Sp. HOV.

TYPE — M. C. Z. 10,555. Brazil: Chapada (H. H. Smith).

Marked on the "same pl^n as D. elegans, but the markings much darker, less
broken up, broader and tending to form bands, the four costal marks before
stigma extend more than one half way across the wing, while the numerous
small spots in the hind part of the wing are so arranged as to almost form
bands with the costal marks; the apical mark consists of a dark preapical band
and an apical spot. In the hind wings the marks also almost form bands;
the spot over the forking of the cubitus extends obliquely upward in an un-
broken band; the apical mark consists of three spots, but little separated;
markings of the body as in D. elegans, but rather broader. Size, a little larger
than D.

This is perhaps what Navas refers to as the true elegans, but his
variety lepida is the true elegans as Perty's figure plainly shows the
form with reduced spots.

COLPOTAULIUS TARSALIS, sp. HOV.

TYPE.— M.' C. Z. 10,880. Col. : Ward (E. J. Oslar).

In color markings and general appearance close to C. perpusillus. It differs
from that species in lacking a row of black spines on the front side of the front
femora, and in that the first joint of the front tarsus in the male is much
shorter than the second joint, in fact less than half as long, and most important
in the shape of the male genital parts (Plate 7, fig. 104), which seen from the
side show no median projecting part which is characteristic of C. perpusillm.
Of the same size as that species.

ZAPOROTA, gen. nov.

Related to Colpotaulius, but the spurs 0, 2, 2, and the pronotum short.
The male palpi are very short, the second and third joints together scarcely as
long as width of face from eye to eye; the front tibia faintly curved in the male,
almost without spines except two close together at inner tip; front femora
with short dense hair beneath; legs with few spines, last joint of hind tarsus
with several distinct spines beneath; no ocellar macrochaetae ; pronotum
short; bristles of mesonotum in well-defined strips. Venation of type usual
in family, fore wings with rounded tip, membrane not granulate; hind wings
scarcely incised at end of cubitus,

In my table of the family (Can. ent., 48, 1916, p. 118) it will run to
Allegophylax except that it has not a granulate membrane; it differs
in very short palpi, bare front tibia, and different shape of wings.

Last joint of hind tarsus without spines beneath; spurs 1, 2, 3. Distinct
ocellar macrochaetae; male palpi only moderately long. Wing membrane
not granulate; venation about normal, but third fork in both wings is pedicel-
late, fourth apical cell in both wings about as broad as third at base; discal
cells very long in both wings, and in hind pair reaching much before the fork
of the median; first fork of fore wings not extending back of the anastomosis;
radius not bent at stigma.

TYPE. — M. moesta, sp. nov.

In my table (Can. ent., 1916, 48, p. 121) it would run to 29, then,
out on account of spur formula, would not agree with either alterna-
tive. From Hylepsyche it differs in normally divided anal cell, and
from most of the other genera in having ocellar macrochaetae, and
the nongranulate membrane.
