The antennæ are long and slender, consisting of 32 joints. The species named coronatus is black, the abdomen dark red; legs likewise red, the tarsi and and [sic] anterior tibiæ pale. The insect is usually found, according to Jurine, on dry wood, and, when it flies, the abdomen forms a right angle with the thorax.

Pl. 40, fig. 4. generic group is at once known by the singular appearance of the abdomen, which is very long, nearly filiform, arched, and inserted in the thorax a little above the origin of the posterior legs. The hinder legs are thickened, and the antennæ straight and extremely slender. The species above referred to is entirely black, the wings tinged with brownish yellow. It is a native of Jamaica.
