crebre punctulatis ; prosterno bicarinato ; metasterno antice 
truncato ; abdominis laminis nec apicem nec marginem 
lateralem segmenti attingentibus. Long., 1?—211.; lat., 
13—141. 
The black marks on the prothorax are a basal fascia, the front 
margin of which is sinuous, and there are two discal spots immedi- 
ately in front of the basal fascia (in some examples joined to it). 
The black lateral margin of the elytra is dilated in the middle; the 
sutural black margin is more or less dilated a little before the 
apex. This species is apparently near to C. Ripponi, Crotch, but 
differs in being much smaller, with the discoidal vitta of the 
elytra not reaching the base, and constricted in the middle (inter- 
rupted in some examples). I should suppose it to be possibly a 
var. of Ripponi, were it not that Mr. Crotch expressly states 
that in that species the abdominal lamella reaches the lateral 
margin of the segment.

ORCUS. 
O. nummularis, Boisd. Mr. Koebele informs me that this is 
certainly a good species and that its larva is quite different from 
that of O. Australasie, Boisd., of which insect it has been con- 
sidered a variety.
