BRITISH ICHNEUMONS. 269 



and trochanters sulphureous ; hind coxae black and hind femora infuscate. 

 Length, 3 mm. 



Thomson says, " Ej siillsynt i norra och medlersta Europa " ; in Britain 

 the only record is that of Bridgman (Tr. Norf. Nat. Soc. v. p. 611), 

 " Taken occasionally in the neighbourhood of Norwich." I took what I 

 believe to be a male of this species in the New Forest, near Hurst Hill, on 

 3rd August, 1901 ; and Beaumont has an example, so named by Prof. 

 Brauns, which he took at Whitby, in August, 1897. 



OIORHINUS, JVesmael. 

 Wesm. Nouv. Mem. Ac. Brux. 1844, pp. 166 et 202. 



Head not narrowed behind the eyes ; vertex broad but not deeply 

 emarginate ; clypeus broader than long, strongly convex, deeply discreted 

 from face, at apex broadly and abruptly excavate sub-circularly in the 

 centre ; apices of mandibles strongly narrowed, upper tooth long and 

 acute, the lower short and a little inliexed. Antennae somewhat slender ; 

 scape sub-dilated and gaping at apex ; fiagellum filiform, eleventh joint of 

 ? sub-quadrate. Thorax not elongate ; notauli sub-obsolete ; metathorax 

 not produced apically ; areola short, transverse, sub-reniform ; petiolar 

 area sub-excavate longitudinally. Abdomen narrow, elongate-fusiform, a 

 little shining ; petiole slender, elongate, smooth ; thyridii distinct, trans- 

 verse, remote from base ; terebra short. Legs slender, coxae simple. 

 Areolet complete ; nervellus oblique and hardly intercepted. 



The following is the only known species. 



I. pallidipalpis, Wesm.

Lfead slightly buccate, finely punctured, black ; cheeks more strongly 

 punctate, margined and shining ; palpi and sometimes the mandibles pale. 

 Antennae slender, filiform ; fiagellum ferrugineous, at least beneath ; of $ 

 elongate, with central joints externally sub-dilated. Thorax shining, black; 

 mesonotum finely punctate with obsolete notauli ; metathorax scabricu- 

 lous ; areola short, reniform, apically emarginate ; petiolar area sub- 

 impressed. Abdomen black with the thyridii and incisures fulvous ; 

 segments two to four of ? red; first segment straight, narrow and smooth; 

 second finely alutaceous and somewhat dull, its basal impression distinct. 

 Legs slender, red, with anterior coxae and all the trochanters stramineous; 

 hind coxae black, more or less pale at apex, their femora and tibiae 

 towards their apices, base of the latter, and the tarsi, black. Stigma 

 piceous ; radix white ; tegulae fulvescent. Length, 5-6 mm. 



This species closely resembles Phaeogenes argutus superficially, but may 

 at once be known from allied genera by the peculiar structure of its 

 clypeus. 



H. striatiis appears to differ from the present species in its aciculate 

 post-petiole and fulvous $ coxae and trochanters ; moreover, Bridgman
