On the anterior is a large chocolate patch, situated on the middle of the wings, and joining to the anterior edge; between which and the shoulders is another that is much smaller.
Underside: tongue obsolete. Palpi, breast, abdomen, and wings brown, as on the upperside; the latter immaculate, except a dark patch on each wing near the shoulders. Margins of the wings slightly dentated.
