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.

 apically broadly rounded ; mandibular teeth of subequal length ; 

 eyes of $ hardly, of tf strongly, convergent above ; ocelli sub- 

 contiguous to the eyes. Antenna? not extending beyond the 

 postpetiole, flagellum generally subattenuate basally. Thorax
