coxal cavities. The var. dejeani, Hope, has an orange stripe on 

 each elytron. The insect has nothing to do with C. bicolor, Eab., 

 with which it has been considered synonymous and with which it 

 may superficially be compared ; it might perhaps be placed in the 

 C. aurofasciata section, towards which it has distinct affinities.

Much larger than C. bicolor, with which it has been confused, 

 and of a darker, duller and more uniform colour ; upper surface dark 

 cyaneous, with a slight greenish tinge, almost black, with the sides 

 of the labrum, head, pronotum, and elytra shining green, the 

 colour on the latter being duller ; the clypeus and front of the 

 head are also green : head broad, eyes not as prominent as in 

 C. bicohr ; pronotum very slightly narrowed at base ; elytra dull, 

 immaculate, with the sculpture very fine, but more distinct than 

 in the allied species ; underside more or less violaceous, abdomen 

 without the reddish margins and apex, and with the pubescence 

 much more scanty, and almost wanting, but apparently fugitive. 



Length 22-23 millim. 



Bengal : Chota Nagpur, Palkot, Sahibganj. 

 Var. dejeani, Hope. 



This variety has the elytra ornamented throughout their length 

 with a yellow stripe, starting from the shoulder and becoming 

 widened behind. It has occurred in Chota Nagpur with the type- 

 form, and there is a specimen in the British Museum from 

 Berhampur : it has also been recorded from Murshidabad. It 

 appears to be a very rare insect. 



Group 18. 



Large black species with the head and pronotum very strongly 

 rugose, and the elytra smooth, with conspicuous orange or yellow 

 markings ; underside black, smooth and shining, as a rule practi- 

 cally without pubescence. (Length 19-23 mm.) 



Key to the Sjoecies. 



I. Elytra more convex and less parallel- 

 sided, humeral markings crescent- 

 shaped and extended almost or quite 

 to the suture, forming a more or less 

 distinct common cruciform yellow 



patch aurofasciata, Dej., p. 407.
