The wingspan is about 32 mm. The forewings are white shaded with grey. There are two transverse ochreous antemedian lines and a median line from the inner margin to vein 2, where it disappears in a broad shade. There is a transverse distinct line from the costa to vein 2 beyond the cell. The hindwings are white with a transverse dark line from the angle to the costa and another from the costa beyond the cell to vein 2. The margins of both wings are bordered by a dark, thin, double line enclosing a paler portion.
