Perilissus | BRITISH ICHNEUMONS. 263 

Unmistakable in the very dull thorax and head, in the size of the 
latter, combined with the black hind legs and immaculate red anus. The 
36 has not before been described. 
Holmgren knew a single Q captured in Smolandia in Sweden by 
Boheman, and it was probably this that Thomson reviewed in 1883; 
Gaulle records the species from France in 1908. It has not hitherto 
been noticed in Britain, but I possess a full series of five examples, com- 
prising both sexes, which was captured, presumably in the neighbourhood 

of Shere in Surrey, by Dr. Edward Capron some twenty years ago ; anda 
? found at Felden in Herts by Mr. Albert Piffard about the same time. 
The ¢, so well figured by Stenton, was taken by him at Wimbledon 
Common in Surrey during June, 1909.
