232 BRITISH ICHNEUMONS. [Heteropelma 



bred from puj)ae of Panolis piuipcrda and HyJophiJa prasinana by Brischke, 

 Fidonia piniaria by Kawall, from specimens of Anaria myrtilli by Schm. 

 and Litniifia I'an'aia by Gaulle. Bridg. -Fitch, however, correctly con- 

 sidered it rare in Britain and there seem to be no records ; it must never- 

 theless be widely distributed, since the two in IMus. Brit, are from Epping 

 Forest and Fsher, I possess a female taken at Forres in Elgin during 

 Sept. 1892 (Chitty), another from Cornworthy in Devon (Marshall), and 

 both sexes in July from Miss Chawner and Mr. Adams at Lyndhurst in 

 the New Forest, where I captured a pair on 12th July, 1909, flying over 

 heather at Setlev. It is probably attached to fir woods.
