Trickocryptus.\ BRITISH ICHNEUMONS. II 



more than a constant variety of the first) is now recorded hence for the 

 first time. 



I do not find that Dapanus, Forst., is synonymous herewith, and it 

 certainly cannot be the same as Sobas, Forst., as indicated by Ashmead 

 (Proc. U.S. Museum, 1900, p. 29), nor can I find that Forster described 

 Trichocryf^tus as there stated. The name Sobas, as noted by Sclimiede- 

 knecht (Ent. Nachr. 1890) is preoccupied in the Coleoptera.

Head narrower than thorax, black ; temples not narrowed behind the 

 eyes, frons finely reticulate, face pilose ; labrum apically free, palpi rufes- 

 cent. Antennae reaching slightly beyond apex of the thorax, filiform, with 

 the scape excised to its centre ; of ? somewhat incrassate towards the 

 obtuse apex, and the flagellum basally attenuate, with the first joint dis- 

 tinctly curved externally, and the third to the tenth rufescent ; of $ pilose, 

 setaceous and entirely black. Thorax oblong, a little compressed, some- 

 what dull and immaculate ; mesonotum very finely punctate, with notauli 

 distinct and entire; mesosternal sulci nearly entire, epimera punctate; 

 metathorax not transverse, finely rugulose, with long white pilosity, com- 

 plete upper areae, and large though apically obtuse apo[)hyses ; areola 

 rectangular or elongate, emitting the strong costulae from before its 

 centre; petiolar area entire and sub-vertical. Scutellum a little convex, 

 densely pilose and obsoletely punctate ; of c^ black and of ? entirely, or 

 broadly at the apex, white. Abdomen sub-convex, pilose and shining ; of 

 9 oblong-ovate, slightly broader than the thorax, of ^ sub-lanceolate; 

 black, with the seventh dorsal segment, and apices of all the ventral, white, 

 the three basal rarely apically badious ; post-petiole slightly convex and 

 laterally margined, of 9 entirely glabrous and as long as apically broad, 

 with inconspicuous spiracles, of $, elongate and gradually dilated towards 

 the sub-strigose apex, bicarinate throughout, with prominent spiracles ; 

 terebra nearly half the length of the abdomen, straight, with the spicula 

 red. Legs red and somewhat elongate; the fuscescent tarsi setiferous 

 beneath, claws strongly curved and simple ; c? with apices of the hind 

 femora and tibiae black, and joints three and four of all the tarsi basally 

 white. Wings slightly infumate, with the stigma not broad, and the lower 

 external angle of the disc(jidal cell rectangular, its fenestra entire ; radix 

 and tegulae not pale ; nervellus strongly sinuate and intercepting the 

 recurrent nervure slightly above its centre. Length, 5-9 mm. 



In Britain the males are much rarer than the females, and the majority 

 of those I have seen have the hind femora and tibiae entirely red and the
