(I'l. wii, Fig. 5, 9 .) 



Head romuled. Eyes small, protuberant, hairy. Ocelli 3, in a triangle. 



Antenu.T, in 9 , 12-jointed, clavate, the scape cylindrical; the pedicel 

 longer than the first flagellar Joint, the second to the last transverse- 

 moiiiliiorin, slightly pedicellate, the last oval, twice as long- as the pre- 

 ceding'; in S , 14:-jointed, tilitbrni. 



Maxillary palpi obsolete; labial palpi not jointed.

Front wings with the submarginal vein not reaching the costa, termi-

Hind wings veinless. 



Abdomen oWong, oval, petiolate. 



Legs normal, the femora stout, clavate; the tibiie subclavate. 



This genus has not yet been discovered in our launa, and the single 

 species described by Haliday, from England, is the only one known. 



Tribe II. — BiAPRiiNi. 



In this tribe, the furthest removed from the Belytinw, the submargi- 

 nal nervure reaches the costa at one-third its length or a little before, 

 the costal cell being most frequently open; or the costal and subcostal 

 nervures are confluent as in the Braconhlw {Loxoiropa^ Basalys, etc.); 

 or it is not, or l)ut slightly, developed ( Galesus). Eleven genera having 

 these characteristics in common are here brought together. All those 

 of which the parasitism is known, are found living upon Dipterous larvae
