In general appearance, and in the formation of the prothorax, 
this genus resembles the species of the first section of Paussus; 
whilst the formation of tlie antennae leads towards Cerapterus, with 
some of the species of which it also agrees in the incrassation of the 
labial palpi. Between the anterior part of the eyes there are two 
slightly raised tubercles, the centres of which appear excavated for 
the reception of a circular ball, probably capable of a rotary 
motion, upon the upper or exposed surface of which the lower part 
of the basal joint of the antennas is inserted.
