BRITISH ICHNEUMONS. I75 



The variety pallipes appears to differ only in having an elongate white 

 patch at the base of the hind femora; \ds. flavator has the central seg- 

 ments flavous, with their bases ferrugineous. 



[Ichneumon nnipnfatorins, Panz. et Grav., has been considered a variety 

 of the present species by authors following Wesmael, and of ^. unigJittatiis, 

 by Tischbein {cf. Stett. Zeit. 1875, p. 274), but it was reinstated as a good 

 species by Thomson. From C. fossorius it differs in having the abdomen 

 more or less clear red, and from C. divisorius and C. viessorius in its 

 entirely flavidous hind tibiae, &c. ; the (?, moreover, has the hypopygium 

 apically acute, though not acuminate. I know of no authentic British 

 records of this species.] 



C. fossorius is a widely distributed and apparently common species on 

 the Continent, where the female is known to hibernate. Stephens says it 

 is abundant about London, in June and July, on flowers, but he probably 

 mixes more than one species under this name. The only at all reliable 

 record I can find is that of Parfitt, who tells us it is common in Devon, 

 where it has occurred in July ; I have seen two old males in Bignell's 

 collection and it is recorded also from Essex. It has been bred from 

 Vanessa Atitiopa, Leucania lithargyria, Hadena baliica and H, adusta.

Closely allied to C. fossorius, from which it primarily differs in the elon- 

 gate fourth flagellar joint and the usually rufescent central abdominal 

 segments, and, compared with which, the temples of the ? are more finely 

 punctate. All the basal flagellar joints are longer, more slender, and some- 

 times red ; in the 6 the antennae are longer. The apophyses are wanting, 

 the spiracles oval, and the petiolar area of the ? is tri-divided ; the $ 

 has the mesonotum more coarsely punctate and less shining ; the white 

 scutellum is more sparsely punctate. Abdominal segments two and 

 three more or less red, with a concolorous ventral fold ; the S has the 

 ventral fold on these segments fulvous with their apical margins fuscous. 

 The shorter and more slender femora, as well as the anterior tibiae and 

 tarsi, are fulvous ; the cJ coxae are more sparsely punctate and shining. 

 Length, 11-14 mm. 



The male varies in having the thorax and scutellum rarely black, or tlie 

 antennae white-dotted above ; its abdomen, too, is sometimes black. 



Marshall considered this to be a variety of the preceding insect, and it 

 probably has no right to an individual position in our fauna at present, 

 though somewhat widely distributed on the Continent and not unlikely to 

 occur with us ; the female is said to hibernate among moss, but I do not 

 think it has been yet bred.
