and with white hairs, the apices of the hind femora and tibia? 

 hlackish ; pulvilli elongate, claws simple. Wings flavescent- 

 hyaline, with the costa, stigma and radix testaceous, the tegulae 

 flavous, and the nervures blackish. 



Length 12 millim. 



PUNJAB : Simla (Col. Nurse) ; BOMBAY, Karachi (T. R. Bell). 



Type in Col. Nurse's collection. 



Besides its larger size and distinctive coloration, this species 

 appears to differ from the remainder of its congeners in the 

 transverse postscutellum, which in the typical C. elegantida, Schr., 

 is quadrate. 



Mr. Bell's specimen was bred from a nest of a wasp, Eumenes 

 esuriens, F.

GENOTYPE, Exochus crassicornis, Grav. 



Head transverse, with the vertex emarginate and the face 

 strongly protuberant ; inter-antennal carina entirely wanting ; 

 clypeus deplanate and but obsoletely discrete ; eyes not 

 emarginate. Antennae stout, with the scape subcylindrical ; 

 flagellum filiform, of J as long as the body and apically attenuate, 

 with the joints elongate and the fifth basally emarginate; of $ 

 short, with the joints subtransverse and externally subdenticulate. 

 Thorax deplanate, with the epomiae wanting and epicnemia entire; 

 notauli very distinct and extending to centre of mesonotum ; 

 metathorax somewhat convex and rugulose, with obvious longi- 

 tudinal, but no transverse, costae ; petiolar area subobsolete. 

 Abdomen of 5 oblong-ovate, of c? subcylindrical ; basal segment 

 rugulose, gradually constricted basally and laterally emarginate, 

 with the spiracles slightly before the centre ; remaining segments 

 transverse and nitidulous. Legs subincrassate and not very short t 

 with the tibiae externally setiferous and the calcaria curved. 

 Wings narrow and somew hat elongate ; areolet wanting ; nervellus 

 intercepted below its centre. 



Range. North and Central Europe, Himalayas, Connecticut. 



The strongly deplanate and nitidulous mesothorax and abdomen, 

 and the peculiar conformation of the antenna in both sexes, will 

 serve instantly to distinguish this genus. No male was assigned 

 to it till 1871, when Brischke discovered that sex in Prussia. 



In its deeplv impressed notauli, longitudinally carinate meta- 

 notuin and the excised antennae of the male there would appear to 

 be some connection with the Pimplid genus Lampronola, though 

 the legs are very much stouter, the head anteriorly prominent and 

 the terebra of the female is not exserted.
