Description.
Upperside: the antennae are brown and thread like. The head, body, abdomen, and wings are of a very dark brown, bordering on black, and appear somewhat glossy. All the wings are a little dentated, and on the anterior ones, from the base to the extremity, is a series of black indented lines or bars, whereof the last or outer one is strong and conspicuous, crossing the wing from the anterior to the posterior edges, about a quarter of an inch from the external margin. The posterior wings are marked exactly like the superior.
The underside is of a lighter colour, with the same kind of markings, but fainter. The wingspan is about 2 inches (5 cm).
