British Braconida. 219 



entirely unlike anything constructed 

 by a Braconid (see fig.), and rather re- 

 sembles the pedicellate egg of a Chry- 

 sopa. The cocoons of Perilitus cannot 

 be comi^ared, for they are suspended 

 by a thread, not elevated upon a rigid 

 peduncle. Bignell obtained several of 

 these cocoons from Uropterij.v in the 



same manner, although I have only 



three of his now before me. His ob- ^r~I_^— . Tr_ -- 

 servation is singularly confirmed by 

 the fact that among insects kindly communicated by 

 Parfitt for examination, I find a <? of .4. formosus, 

 accompanied by a similar pedunculated cocoon. This 

 specimen is an old one from Dorville's collection. The 

 Microgasterides do not avail themselves of pupa-cases 

 made by other insects, but manufacture their own ; nor 

 is it likely that the $ of any species constructs a 

 cocoon totally dift'erent in material and design from 

 that of the ? . Some further observations alone can 

 explain this difficulty.
