54 BRITISH ICHNEUMONS. 



the male, among undergrowth, on September T2th, and Wesmael saw it 

 frequently throughout the summer around Brussels. Stephens says it used 

 to be very rarely found around London and in Norfolk, in June and July, 

 which latter record, however, Bridgman overlooks ; Bignell has not found 

 it in Devon though he has seen an example recently taken at Hollington, 

 near Hastings ; and I do not know that it has ever been bred.

Bignell has bred this species in S. Devon, from Tephrosia extersaria, 

 and Marshall knew it as British. It is sometimes abundant in woods and 

 fields, in Sweden, where Holmgren found it i?i cop., a rare occurrence to 

 come under observation in the genus Ichneumon. On the Continent, 

 where it is also found in France and Belgium, it has been bred from 

 Fidonia piniaria and Lithosia rubricoUis.
