The male of this species resembles the female in the form of the abdomen and node of the peduncle, they are, however, smoother and more highly polished; all the specimens which I have examined are of a paler colour, being more or less obscurely ferruginous; the head narrower than the thorax, the eyes large and prominent, and the antennae three-fourths of the length of the body.
