d 2 . A small testaceous red species, with sparse markings 

 and the hind tibia) at both base and apex, black. Head testaceous, 

 with the mandibular apices, and sometimes the occiput, alone

 Fig. 152. Mesochorus f adults, Bridg. black, with base of first and

 distinctly aciculate, though usually glabrous and always with its 

 spiracles central ; second segment transverse and strongly dilated 

 apically ; terebra straight and somewhat slender, black, and as 

 long as the second segment ; <3 valvulae ttavous and elongately 

 exserted. Leys testaceous, with the hind femora subfulvidous ; 

 hind tibiae black at both base and apex, with the tarsi blackish 

 and the coxa? externally subinfuscate ; hind calcaria shorter than 

 half the metatarsus ; claws and pulvilli minute. Wings with the

 Type in the Norwich Castle Museum. 



The Indian examples I have seen differ from Bridgman's 

 description only in having the postpetiole aciculate ; specimens 

 from the same brood as the type, given me by Bignell, bear no 

 trace of aciculation. One of the former, too, has the mesonotum 

 entirely black. 



This species has hitherto been known only from Britain, 

 Sweden, and Denmark. It is known to be hyperparasitic,
