278 BRITISH ICHNEUMONS. [Spilocrypius. 



The male sometimes has the scape immaculate, a white dot beneath the 

 radix, the coxae and trochanters immaculate, and the base of the anterior 

 femora is usually black. 



It is very like ^S". ////Vnz/^r, but a little smaller ; the cheeks are buccate 

 and the head somewhat narrowed behind the eyes, the female post petiole 

 is less transverse and its carinae are a little elevated, the second segment 

 is more closely and much more finely punctate, the epistoma is less pro- 

 minent, the terebra is consideral)ly longer and its hind femora are apically 

 more broadly, with the trochanterellus entirely black ; the white coloration 

 of the male is less profuse. 



The male variety migrator has a dot on the scutellum, generally the 

 post-scutellum and sometimes the pronotum anteriorly, and dots on the 

 metathorax, white. 



^. fumipeiinis is not uncommon throughout northern and central 

 Europe in May and June, but it has been much overlooked in Britain, 

 whence it was first recorded by Desvignes in 1856. Perkins bred five 

 males and three females at Wotton-under-Edge from cocoons of Zygaena 

 finpendulae, which he had collected just twelve months before (Entom. 

 1880, p. 69), and Bridgman from Saturnia carpitii (I. c. 1881, p. 139) ; on 

 the Continent Tschek records it from Psyche viciella and Laboulbene from 

 Zygaefia laeta. Chapman has given me both sexes, bred from Psychids at 

 Locarno ; and Miss Chawner the only British specimen I have seen, from 

 the New Forest,
