This species has much resemblance to Callichroma afrum, 
Linn., but may be distinguished by the following differences :— 
Altogether the head, thorax, and elytra are shorter ; the latter 
are parallel, and do not become more attenuated posteriorly, 
and, instead of being green passing into whitish, are coppery- 
green; and, moreover, the antennz, instead of being ferrugi- 
nous, are black. 
Rare. In my collection.
