Hophcrypftis.] BRITISH ICHNEUMONS. 29I 



segments closely and finely punctate ; terebra hardly shorter than abdo- 

 men. Legs black, femora slender and not inflated, hind legs elongate ; 

 femora and anterior tibiae entirely red ; hind tibiae apically infuscate, 

 basally red in 9 , white-banded in S ; tarsi infuscate, the hind pair 

 centrally white in both sexes. Areolet emitting recurrent nervure from 

 a little before its centre, of S sub-cjuadrate ; radial nervure apically 

 inflexed. Length, 8-12 mm. 



This species differs from H. co)ifector in the basal segment not being 

 dilated, the spiracles of the metathorax rotund and the upper wings with 

 the ordinary transverse nervure situated before the cubital fork. The 

 female is said to be much like that of P. peregrinator, but its hind femora 

 are much longer and not incrassate, with the basal segment less glabrous 

 and carinate. C. albi/s, which has somewhat the facies of C. albatorius, 

 is considered distinct by Schmiedeknecht, but a comparison of Taschen- 

 berg's description with Thomson's male leaves little doubt that Brischke is 

 correct in considering them synonymous. 



I can find no mention of this species as British till T. Wilson bred it 

 from rose sticks, in which it was parasitic upon the saw-fiy, Emphyius 

 ductus (cf. Entom. 1883, p. 33), though it is widely distributed throughout 

 Europe.

Clypeus often angularly produced at apex. Thorax usually broadly red ; 

 metathorax densely tomentose ; coxal areae distinct. Post-petiole bi- 

 carinate, glabrous or finely punctulate ; anus white. Onychium with the 

 pulvillus and claws stout and elongate ; tibiae mutic and in $ inflated. 

 \Vings somewhat narrow ; areolet large and parallel-sided, rarely externally 

 incomplete. 



Thomson somewhat extended Forster's genus, and authors are conse- 

 quently at variance as to its correct name ; but, since the former himself 

 acknowledges this synonymy, the earlier name is here adopted, although it 

 may be open to doubt whether A. signaiorii/s, a common British species 

 which finds no place in the last European review of this genus, should be 

 included or raised to generic rank. Only five certified and two doubtful 

 species are referred to this genus on the Continent.
