l62 BRITISH ICHNEUMONS. 



red, of S flavous with segments five and six discally infuscate. Legs 

 normal, glabrous, flavous or fulvous ; coxae black, with the anterior of $ 

 red, of S flavous, beneath ; hind coxae broadly flavous above. Wings 

 normal, of 9 flavescent, of S sub-hyaline ; areolet pentagonal, narrowed 

 though not cjuite coalesced above ; nervures and stigma fuscous or 

 piceous ; radix and tegulae fulvous. Length, 14 mm. 



Mr. Gorham gave me also a male and female of this species, which were 

 mixed with the preceding ; and it is curious that two such obviously 

 closely allied kinds should yet so materially differ in markings and sculp- 

 ture, both having been probably bred, and previously unnoticed.

Sub-equilateral, with clypeus apically sinuate. Head stout, not narrowed 

 behind eyes ; cheeks of ? slightly buccate ; clypeus immarginate and, 

 especially in $ , emarginate ; mandibles stout ; labrum exserted. Antennae 

 somewhat short, hardly attenuate towards apex. Thorax sub-linear, punc- 

 tate, narrower than head ; metanotum with distinct areae ; areola elongate, 

 rectangular ; spiracles linear. Abdomen elongate, sub-linear, narrow with 

 anus acuminate ; central area of post-petiole twice broader than lateral 

 ones ; second segment a little longer than broad, third quadrate ; terebra 

 slightly exserted. Legs not stout \ tarsi not dilated. 



This genus is certainly better placed at the end than at the beginning, 

 as has been the usual practice of the authors, of the Oxypygini, on account 

 of its affinity with the first of the Ainblypygini^ as pointed out by Thomson 

 (Annales Soc. Fr. 1888, p. in). The two species — excluding Ichneiiinon 

 lusens^ Grav., tentatively herein placed by Wesmael — known on the Con- 

 tinent, both occur in Britain ; one is very common with us, but the second, 

 which is now for the first time recorded hence, would appear to be rare or 

 to have been previously overlooked.

Head closely punctate, not narrowed behind eyes, black ; mandibles 

 and labrum usually rufescent ; cheeks and clypeus glabrous with isolated 

 punctures, latter hardly discreted and apically distinctly emarginate, slightly 

 produced centrally ; face rather flat, confluently punctured ; S with juxta- 

 antennal always, and occasionally the facial, but never the frontal, orbits 

 white. Antennae black, of $ filiform, slightly attenuate towards base, 

 tricoloured ; of S setaceous, distinctly setiferous, joints beyond middle 

 somewhat nodulose, apex attenuate, piceous beneath and very rarely (van
