General DescriptionA medium-size (3.5-4.2 cm wingspan) pale grey moth. The forewings have a prominent black basal dash, which forks upward and downward at the antemedian line, and a thin, prominent black streak through a dark patch ("dagger-mark") in the anal angle. The cross-lines, with the exception of the postmedian line, are incomplete and indicated mainly by black marks where they meet the costa. The orbicular is a prominent pale spot narrowly outlined in dark scales. The reniform is vestigial, and consists of a dark marking the proximal side. The postmedian line is complete, s-shaped, doubled, and filled with white scales. The fringe is checkered, with the dark scales between the veins. The hindwing is dirty white in the male, darkening near the outer margin and along the outer veins, and light grey with a faint postmedian band in the female. Antennae in both sexes simple.
