 blackish ; pulvilU elongate, claws simple. Wirir/s flavescent-

PuNJATJ : Simla {Col. Karse); Bombay, Karachi {T. R. Bell). 



Type in Col. Nurse's collection. 



Besides its larger size and distinctive coloration, this species 

 appeal's to differ from the remainder of its congeners in the 

 transverse postscutellum, which in the typical C. eler/aniuhc, Schr., 

 is quadrate. 



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

 esuriens, E.

Head transverse, ^ith 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 ; 

 rtagellum filiform, of c? fis long as the body and apically attenuate, 

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

 short, with the joints subtransverse and externally snbdenticulate. 

 Thorax deplanate, with the epomise 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, costse ; petiolar area subobsolete. 

 Abdomen of $ oblong-ovate, of S 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 verj^ short, 

 with the tibiae externally setiferous and the calcaria curved. 

 AVings narrow and somewhat elongate ; areolet wanting ; nervellus 

 intercepted below its centre,

The strongly deplanate and nitidulous mesothorax and alxlomen, 

 and the peculiar conformation of the antennae 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 deeply impressed notauli, longitudinally carinate meta- 

 notum and the excised antennas of the male there would appear to 

 be some connection with the Pimplid genus Lampronota, though 

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

 the terebra of the female is not exserted.
