The species on which I found this genus has much general 
resemblance to Cyrema nigellum, Blackb., but its clypeus being 
dilated widely (quite as much so as in any Orcus or’ Chilocorus) 
on the sides in front of the eyes seems to forbid placing it in 
Cyrema. It may be distinguished from Serangium (which has a 
somewhat similar clypeal structure) by its finely-granulated eyes 
and from Lipernes by the under-surface of its body being deeply 
sulcate for the reception of the legs.

The species for which it is necessary to form this genus is very 
similar in general appearance to Gymnoscymnus, Bucolellus, and 
Serangium, but a glance at the structural characters will show 
that it cannot be placed in any of them. In Dr. Chapuis’ arrange- 
ment of the Coccinellide its place is in the Bucolites. In my 
tabulation of the Australian Coccinellide (Trans. Roy. Soc., XT., 
pp. 1886-7) it falls into the Division “AA” along with Serangium 
and Cyrema, from both which the following characters in com- 
bination will distinguish it:—Prosternum not abnormally pro- 
duced in front, nor having the mediau space abruptly flat.
