The markings are blackish fuscous, finely edged with whitish ochreous and there is an irregular triangular dorsal blotch before the middle, reaching four-fifths across the wing, confluent on the dorsum with a triangular posterior dorsal patch of dark fuscous suffusion, the apex of which reaches the costa at three-fourths, its posterior edge is limited by a nearly straight fine whitish-ochreous line. A small spot is found on the costa before the middle, and a small oblique oval spot in the disc beyond the middle. The hindwings are pale ochreous, the apex and termen narrowly suffused with fuscous.
