 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, giveii me bv Jjignell, 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, 

 through the Bracouid, Apanteles popv.Jaris, Plal., on Eachelia
