British Braconidce. 53 



Only four instances of the parasitism of these insects 

 have been brought to light, from which it appears that 

 they attack Coleoptera. Cosmophorus Klugii, Katz., 

 was bred out of Polygraphia pubescens, Er., and Perilitus 

 terminatus, Nees, from adult Coccinellce, but ^ neither 

 parasite has been noticed in England. Euphorus 

 paUidipes, Cur., has been reared from Orchesia minor, 

 Walk., and Perilitus falciger, Kuthe, from Timarcha 

 coriaria, F.
