The female, which in colour and depressed form resembles the 
male, differs from that sex in having the interstices of the elytra 
thickly and strongly punctate. As is the case in the other species 
of this genus, the armature of the mandibles is subject to con- 
siderable variation; in small male specimens the subapical tooth 
is entirely wanting.

One of the minor species of the genus, remarkable for its 
smooth and polished appearance, and allied to Agus myrmidon, 
Thomson, from which species it differs, however, in its more 
parallel and convex form, in the anterior part of the head being 
scarcely emarginate, in the rounded sides of the prothorax, and 
in the more delicate striation of its elytra,
