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.

irregularly and weakly areated centrally ; spiracles small and very
shortly oval. Abdomen distinctly petiolate, with the spiracles far

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
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.

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.

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

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*
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
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
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.

Legs not very slender ; hind femora stout, with a strong obliqun

various small Tortricid and Grelechiid moths, and I once bre.I

distinctions, in the absence of which it is idle to consider it a new

This genus was differentiated from Pristomerus by its entire

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),
