TAKTTIA. — PBISXOMERUS, 507 



At once recof^nised from Camerou's four other specie?; by the 

 second recurrent being emitted from the external cubital nervure 

 at an appreciable distance further from the base of the wing than, 

 the submavginal nervure, though he failed to note this distinction. 



The black and aciculate two basal segments are very distinctive. 



1 am strongly of opinion that this species should be transposed 

 to Cremastns 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 tliat of Tarijtla. 



This appears to be an extremely common species in Bengal 

 and there is a very long series in the Pusa collection, the niajoritv 

 of -which were bred f]-om the Pyralid leaf-rolling caterpillar of 

 Antigastra catalaunalis, Dup. It is also represented by specimens 

 raised from the Tortricid, Eucosma pararjramma, Meyr., thfr 

 Pyralids, ClnJo simplex, Butl., Euzopliora perticella, Eag., and the 

 larva of another undetermined Pyralid, feeding on Acacia arabica. 



Tribe PllISTOMERIDES. 



This tribe is instantly recognised from the remainder of the 

 Ophioxix.e 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 Odontomerus, Grav., though they have hardly 

 another feature in common. It is closely related to Ceemastides 

 in the large stigma, broad A\ings, 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 

 sliould be referred to the following genus, though his descrii^tion 

 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. 



Genus PRISTOMERUS, Curtis. 



Fristomerus, Curtis, Brit. Eiit. 1836, fol. Gi'4. 



Gexotype, Ichneumon vidnerator, Pz. 



Head narrow on the vertex ; clypeus slightly demarcated and 

 apically broadly rounded ; mandibular teeth of subequal lenglli ; 

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

 contiguous to the eyes. Antenna' not extending beyond the 

 postpetiole, flagellum generally subattenuate basally. Thorax
