H YMENOP TERA A CUL EA TA . 



This again is a very extensive genus, second only to 

 PompUus amongst the Fossores ; we have seven British 

 species. Kohl, in 1884, records 223 known species, of which 

 he says 65 are PaliBirctic. It is distributed over nearly the 

 whole world. All the British species belong to the sub- 

 genus Priociiemis ; they may thus be tabulated : — 



Propodeum pilose .... ruscus. 



Propodeum not pilose. 



Propodeum transversely rugose in the 

 § ; both sexes with a dark, well- 

 defined apical band on the front 



wings AFFINI3. 



Propodeum not transversely rugose ; 

 (J without a defined apical alar 

 band. 



Cubital nervure of front wing pro- 

 duced to, or almost to, the apical 

 margin exaLTAtus. 



Cubital nervure of front wing not 

 nearly reaching the apex. 



Upper basal nervure of front winga in 

 a continuous curve ; pronotal emar- 

 gination very deep in the ? ; (J 

 abdomen generally black, or nearly

Curve of the upper basal nervure dis- 

 tinctly broken at the origin of the 

 cubital nervure; pronotal emargina- 

 tion less deep in the ? ; cj abdo- 

 men red at the base. 

 Legs more or less red ; ? with the 

 clypeus widely polished at the apex ; 

 (J apical ventral segment oarinated obtusivbntris. 

 Legs rarely otherwise than entirely 

 black; ? clypeus entirely dull, or 

 bright only at the extreme margin; 

 (J ventral apical segment not eari- 

 nated. 

 cJ apical ventral valve of the abdo- 

 men notched at the apex, with 

 the sides fimbriated, ? with a 

 clear round spot near the apex of 

 the anterior wing .... pusillus. 

 jj apical ventral valve very narrow, 

 its sides not fimbriated; ? apical 

 clear spot of the wings wanting or 

 ill-defined paevulus.
