'broader than the petiole and very finely aciculate ; terebra black,
very slender and about half the length of the abdomen. Legs
testaceous, with the anterior coxa? substramineous ; hind tibiae
blackish at base and apex. Wings broad and somewhat ample ;
radii and tegula? flavescent, stigma and nervures dull ochreous ;
radial cell short and apically straight ; submarginal nervure longer
than half the recurrent, which is emitted not very closely beyond
it ; basal nervure continuous ; uervellus opposite and neither
.geniculate nor intercepted.

Length 5-6 millim.

BENGAL : Pusa, i. 06 and xi. 07.

Type in the Pusa collection.

Extremely similar to the species of Tarytia, but at once recog-
nised by the interception of the external cubital nervure by the
second recurrent distinctly beyond the submarginal.

A unique pair of this pretty little species was bred at the
Agricultural Research Institute at Pusa from the Pyralid moth,
Antigastra catalaunalis. There, too, is a male with the occiput,
antennae, thorax and abdomen almost entirely black, render-
ing it superficially very distinct in appearance, though 1 find no
structural distinctions ' and propose to term it var. nigrescens;
it was bred from the hairy caterpillar of the Arctiid moth,

Didcrisla obliqua, TV Ik. Paiva took a female of this species, witta
Tarytia Jlavo-orbitaUs, ou board-ship, ten miles off Coconada ou
the Madras coast, on 14th April 1908.

Genus TARYTIA, Cam.

Tarytia, Cameron, Journ. Bombay Nut. Hist. Soc. 1907, p. 088.
GENOTYPE, T. basimacula, Cam.

Clypeus distinctly discrete from the face and apically broadly
rounded ; mandibles with the teeth large, divergent and of equal
length ; cheeks distinct and not sulcate ; eyes nude, internally
parallel and not einarginate. Antennae exactly filiform and of
normal length. "Nbtauli sometimes present ; metathorax not at all
rugose, apically subproduced beyond base of hind coxae ; metanotum
irregularly and weakly areated centrally ; spiracles small and very
shortly oval. Abdomen distinctly petiolate, with the spiracles far
beyond centre of the basal segment, which is longer than the
second, with the postpetiole distinctly nodose; ovipositor distinctly
exserted, but not elongate, with filiform valvulae. Intermediate
tibiae bicalcarate ; hind calcaria nearly as long as the second tarsal
joint ; femora not dentate ; tarsi normal, not at all spatuliform,
with simple and not pectinate claws ; basal joint of hind onea
nearly as long as the following three united ; hind coxae stout,.
two and a half times as long as broad. Stigma not broad nor
radial cell short ; areolet entirely wanting ; second recurrent
nervure distinct and fenestrate above its centre, emitted at or
beyond the submarginal ; basal nervure continuous ; parallel
nervure intercepted shortly above its centre ; hind wings with the-
nervellus neither intercepted nor geniculate, and all the nervures
apically pellucid.

Range. India.

This genus does not bear the remotest relationship to Agrypon*
with which Cameron compares it ; I have not seen Szepligeti's
arrangement, to which he refers, but its whole facies is entirely
Cremastid. An examination of the whole of the type specimens
has enabled me to draw up the following table of species, though
it is possible that in some instances the two sexes have been
described as distinct species since, with a single exception, all the
species have been founded on single specimens.

tate, frons and vertex somewhat more strongly punctate, with the
frons centrally elevated and rufescent. Antennae infuscate-brun-
neous, \vith the flavous scape black above. Thorax with the

with flavous stripes on either side of a broad black central
stripe at the apical two-thirds ; radical foveae, and a broad and
apically curved mark on basal third of metanotal disc, black ;

BOMBAY: Deesa, x. 98 (Col. Nurse).

Type in Col. Nurse's collection.

Very distinct from its congeners in the dull and granulate
scutellum, the entire lack of any trace of the notauli, and in the
continuation of the second recurrent nervure with the sub-
marginal.



t Mr. Green has sent me a fragment of an interesting new species
("No. 857") which he bred at Peracleniya in Ceylon, in December 1901,
from a fruit of Solanum inclongela, infested by larvae of the Pyralid moth
Leuoinodes orbonalis. It is larger, with darker stigma, than any described
Tarytia and approaches T. cariniscutis in its entire mesonotal notauli.

596. Tarytia empusa. sp. n.

~ cJ . A very small, testaceous species, with the head (except
ocelli), legs, second abdominal segment, tegulae, and apex of
scutellum, flavous ; ocelli, antennae, disc of metanotum, and of
iirst and fourth segments, infuscate ; basal metanotal area as long
as the areola.

Length 3| millim.

BENGAL : Pusa, ix. 06.

Type in the Pusa collection.

This species is too closely allied to T. niyromaculata to need a
detailed description ; besides its coloration and much smaller size,
it differs therefrom in the metanotum being much more nitidulous,
with all the areolar caring stouter and more clearly denned; the
basal area is strongly elongate, the head less emarginate posteriorly,
the postpetiole gradually dilated from its centre and not abruptly
from its apical third, and the second segment is not more than
twice as long as broad.



397. Tarytia cariniscutis, Cam.

Tari/tia cariniscutis, Cameron,* Jouru. Bombay Nat. Hist. Soc.

<5 . A clear pale testaceous species. Head (mutilated) with the
face and clypeus closely punctate. Antenna 1 infuscate, paler
below, with the scape flavous. Thorax closely, but not strongly,
punctate ; metanotum with very distinct notauli ; petiolar area
distinct and triangular, with the lateral carinae broad and basal ly
coalescent; areola feebly and sparsely striate, broad, roundly
constricted basally and subconstricted towards the apex, extending
to shortly beyond the centre ; propleura? glabrous. Scutellum
closely punctate and laterally carinate to near its centre, strongest
at base. Abdomen with the basal half of the second and third
segments discally, and the latter laterally, black ; anus black ;
second segment discally finely and closely, base of third more
obsolerely, aciculate; valvuke broad, elongate and strongly exserted.
Legs immaculate. Wings clear hyaline, with the stigma and
nervures pale testaceous.

Length 8 millim.

This species is said to be recognised by the scutellum being
carinate beyond its base, and by the large and distinctly defined
petiolar area ; from the remaining four species it differs in its
elongate notauli, which extend strongly to the pin run through
the disc, in its shining and not very closely punctate scutellum
and in the second recurrent nervure being continuous with the
submarginal.

$ . A testaceous red species. Head flavous, with the ocellar
region triangularly black ; face and base of clypeus closely punc-
tate, the latter apically glabrous ; frons and vertex closely, but
more strongly, punctate ; scrobes elongate and deeply impressed,

separated by a cariua ; eyes large and internally parallel ; ocelli
large and pale, with the basal pair further apart than from the eyes.
Thorax : mesonotum closely punctate, with two broad flavescent
stripes ; metanotum rugosely punctate, with indistinct carinae and
the apical declivity strongly trans-striate ; pleurae closely and
distinctly punctate, with the meso- and meta-pleurae broadly fulvous
basally. Scutellum roundly convex. Abdomen with the Hrst seg-
ment basally, and the basal half of the second discally, black ; anus
infuscate ; second segment and the postpetiole closely and dis-
tinctly aciculate ; third basally substriate ; terebra 2 millim. in
length. Leys somewhat paler than the body and immaculate. Wings
hyaline, with the stigma dark testaceous and the nervures black.

Length 8 millim.

Type in Col. Xurse's collection.

I am strongly of the opinion that this is the alternate sex of
T. cariniscutis, but since they have been described as distinct and
we at present know but single examples of each species of the
genus, it is better to treat them temporarily as different, more
especially as the present specimen has the notauli eutirely apical
and not extending to the disc, while in T, cariniscutis they extend
to the centre of the mesonotum.

TARYTIA.. PBISTOMEBUS. 507

At once recognised from Cameron's four other species by the
second recurrent being emitted from the external cubital nervure
at an appreciable distance further from the base of the wing than
the submarginal nervure, though he failed to note this distinction.

The black and aciculate two basal segments are very distinctive.

I am strongly of opinion that this species should be transposed
to Cremastus on account of the analogous neuration ; but the
metanotum is somewhat more produced than is usual in that genus
and its facies is altogether similar to that of Tarytia.

This appears to be an extremely common species in Bengal
and there is a very long series in the Pusa collection, the majority
of which were bred from the Pyralid leaf-rolling caterpillar of
Antigastra catalaunalis, Dup. It is also represented by specimens
raised from the Tortricid, Eucosma paragramma, Meyr., the
Pyralids, Chilo simplex, Butl., Euzophora perticella, Bag., and the
larva of another undetermined Pyralid, feeding on Acacia arabica*



Tribe PRISTOMERIDES.

This tribe is instantly recognised from the remainder of the
OPHIONINYE by the usually strong and elongate hind femoral
tooth, followed by a series of serrations in the typical genus or
close to the apex in Pristomeridia, Ashm. ; and this allies it to the
Pimplid genus Odontomems, Grav., though they have hardly
another feature in common. It is closely related to CBEMASTIDES
iii the large stigma, broad wings, and single elongate submarginal
nervure.

The only species of this tribe hitherto recorded from India was
placed by Cameron in Pristomeridia, but from his account of the
subapical serrations of the hind femora it is obvious that it
should be referred to the following genus, though his description
of the metanotum is too vague to determine the shape of the
areola.

This tribe is universally distributed, since Tosquinet has de-
scribed several kinds from Africa and Cresson others from
America, but the known species are very few in number, hardly
amounting to a dozen in all.

4ipically entire, with the costuloe strong. Basal abdominal seg-
ment apically somewhat broad, with distinct glymmal sulci ; second
segment with the epipleurae iuflexed ; terebra slender and exserted.
Legs not very slender ; hind femora stout, with a strong obliqun
tooth slightly beyond the centre, followed bv small subcrenulate
processes ; hind calcaria of unequal length ; fifth tarsal joint
longer and a little broader than the fourth, with the short claws
pectinate. Wings with the stigma large and broad ; areolet
entirely wanting ; discoidal cell not elongate, but with its lower
external angle subacute; lower wings with the median nervure
not basally obsolete, nervellus subgeniculate below its centre.

The species of this very distinct genus are known to prey upon
various small Tortricid and Grelechiid moths, and I once bre.I
numbers in a room of stored apples, where they emerged, in all
probability from the codlin moth (cf. Zoologist, 1909, p. 213)
though not elsewhere recorded as a parasite of this species.

I am not entirely satisfied that the present species is indeed
distinct from the well-known P. vulnerator, Grav. ; the above
sexes differ somewhat in coloration, and further, the 6 from
Mt. Abu has the head mainly and the thorax entirely bright red,
with the legs nearly entirely' black, yet I can trace no structural
distinctions, in the absence of which it is idle to consider it a new
species. P. vulnerator is known to range throughout nearly the
whole of Europe, and quite possibly extends to Asia.

Pristomeridia, Ashmead, Proc. U.S. Nat. Mus. 1900, p. 100.

GENOTYPE, Porizon agilis, Cresson.

This genus was differentiated from Pristomerus by its entire
and not geniculate or intercepted nervellus, pentagonal aud not
hexagonal areola, the scarcely thickened hind femora, the tooth of
which is near the apex and not merely slightly beyond the centre.
It was erected for the reception of a single species, described
from Texas by Cresson (Trans. Amer. Ent. Soc. 1872, p. 175),
and referred by him, with some hesitation, to the genus Porizon.
Our Indian insect certainly belongs here, though the areola
is hexagonal and the femoral tooth is at some distance from the
apex.
