268 BRITISH ICHNEUMONS. 



Head sub-tumidous, black ; clypeus imperfectly discreted ; palpi and 

 the weak mandibles pale. Antennae very slender, filiform ; basal flagellar 

 joints elongate ; fulvous, somewhat darker above ; scape of $ sub-infuscate. 

 Thorax mainly red : pronotum of 6 flavidous ; metathorax black ; areola 

 not longer than broad, basally rounded and apically truncate ; costulae 

 sub-obsolete ; petiolar area not impressed ; mesosternal sulci short and 

 deep. Scutellum sub-elevated, convex, red. Abdomen elongate, narrow, 

 red ; with the first segment, except usually its apex, basal half of fifth and 

 of sixth and most of seventh, black ; three or four apical segments of ? 

 black ; post-petiole convex, glabrous and shining ; impression deep, entire 

 and situated in the basal third of second segment ; terebra exserted. Legs 

 slender, red ; coxae and trochanters fulvous or stramineous ; ° with apex 

 of hind femora and tibiae, and often base of latter, infuscate ; coxae mutic. 

 Stigma fuscous ; radix and tegulae white. Length, 5-8 mm. 



The mesonotum is sometimes more or less infuscate, and Brischke refers 

 to examples with the thorax and scutellum entirely black (var. Brischkei, 

 Berth.). 



Besides the points already indicated, this species is very distinct from 

 the rest of the genus in the conformation of its body, its gibbulous scu- 

 tellum and very slightly produced meso- and meta-sterna, which characters 

 ally it with Ischnus. 



This is undoubtedly quite a common species in Britain. Mr. A. Beau- 

 mont has taken it at Appledore, in August ; Mr. Tuck, at Tostock and 

 Finborough Park, in Suffolk, in September; Bridgman, at Eaton, in July; 

 and I have found it on Mousehold Heath, near Norwich, early in June, at 

 Bramford early in November, and beaten it from spruce and Scotch fir, at 

 Foxhall and Bentley Woods, near Ipswich, and at Gosfield, in Essex, in 

 April. It is common on the Continent, where Brischke bred it from a 

 Tortrix pupa, on oak. As Holmgren remarks, the male is of much rarer 

 occurrence ; I have seen but one specimen of it, taken probably at Shere, 

 in Dr. Capron's collection.
