The principal characteristic of this genus, is the peculiar shape of 
its head ; being broader in the fore-part (occasioned by the promi- 
nency of the eyes) than behind, or otherwise gradually tapering 
from the eyes towards the thorax. 
The antennæ are thicker towards their extremity than at their 
base. 
The larvæ of many of the Attelabi so greatly resemble those of 
the preceding genus, as scarcely to be distinguished from them.

Their antennæ are formed of articulations or joints, gradually 
diminishing in size from the base to their extremity. 
The thorax is either armed with spines, or gibbous, made un- 
even by small elevations. 
The elytra are narrow, and throughout of equal breadth. 
The Gerambyces are divided into the following sections : 
1. With the thorax on each side armed with moveable spines. 
2. With the thorax margined, and the sides armed with spines. 
3. With the thorax round, and armed with fixed spines. 
4. With the thorax nearly cylindrical, and unarmed, without 
spines. 
5. Those with the thorax of a roundish form, and depressed on 
the upper side.
