Io8 BRITISH ICHNEUMONS. [Panargyrflps. 



declived throughout, apically produced above the hind coxae, with com- 

 plete upper areae of which the areola is hexagonal, entire and elongate ; 

 petiolar area discreted. Abdomen strongly elongate-fusiform and black, 

 with the incisures of the three basal segments very narrowly red and of 

 the remainder narrowly white ; basal segment linear, finely aciculate, 

 centrally sub-canaliculate with prominent spiracles ; the second segment 

 twice longer than broad ; anus of ? compressed, with the terebra hardly 

 shorter than the abdomen. Legs fulvous, of $ with the anterior pairs 

 stramineous ; hind tibiae and tarsi infuscate. Wings normal with the 

 radix and tegulae ilavous ; areolet sub-pentagonal ; stigma piceous, nervelet 

 indicated ; internal cubital nervure parallel with the basal ; nervellus inter- 

 ce]ned below the centre. Length, 6^-8 mm. 



This species has been hitherto known in Britain as ^^ Nemaiopodius" 

 afer (I cannot tell why, for Brischke did not name it so), though Lepto- 

 cryptus clixvigo- figures in MS. in Marshall's own copy of his 1872 

 Catalogue, which I possess. It may at once be distinguished from all 

 the other species of this genus by its black and narrower body, apically 

 bidentate clypeus and the very long terebra. Even in 1883 it was hardly 

 referal)le to Nemafopodiiis, which has the metathorax glabrous and uni- 

 costate, with the areolet small and quadrate ! The villose head, sternum 

 and metathorax, elongate basal segment, deflexed terebra and slender legs 

 place it with certainty in the present genus, among whose species its areolet 

 exactly resembles that of P. teniiipes. 



Capron first took this species in Britain and I have a long series of 

 both sexes in his collection ; males were subsequently found commonly 

 close to Norwich towards the end of May by Bridgman (Trans. Ent. Soc. 

 1882, p. 145), and Marquand records it from the district of Land's End. 

 Brischke bred it from the cocoons of Lophyrus pini in Germany, whence 

 its range extends to Lapland ; and T. Wilson of York in some numbers 

 from Empliytus ductus in Britain.

Marsh. E.M.M. iii. (1867), p. 193. 



Antennae stout and twice longer than head and thorax. Metathorax 

 incompletely areated, rugose and punctulate ; petiolar area indicated by 

 slight lateral carinae. Scutellum conspicuous. Body deplanate through- 

 out " et sub saxis degenti idoneum." Abdomen much longer than head 

 and thorax, dorsally deplanate ; basal segment punctulate and not acicu- 

 late, triangular, basally very broad and gradually narrowed to apex, with 

 no tubercles ; terebra as long as the first segment. Legs with tarsal joints 

 not bilobed. Wings reaching slightly beyond base of metathorax ; radial 

 cell short and ovate, two cubital cells present, areolet wanting, all the 

 nervures stout and pilose.
