The characters of this genus are perhaps as interesting as 
any hitherto presented to the entomologist. ‘The various parts 
of the mouth, especially the development of the palpi and their 
basal scapes, and the internal labium, are worthy of notice, as 
is also the insertion and structure of the antenne. Between 
the upper part of the eyes there are two slightly raised tuber- 
cles, the centres of which appear excavated for the reception of 
a circular ball, probably capable of a rotatory motion, upon the 
. upper or exposed surface of which the lower part of the basal 
joint of the antenne is inserted. In general appearance and in 
the formation of the thorax, this genus resembles the first section 
of Paussus; whilst the formation of the antennz would lead 
towards Cerapterus. ‘There are four joints more in its antennz 
than in Paussus; while Cerapterus exceeds it by four joints 
more. In the incrassation of the labial palpi it approaches 
Cerapterus ;
