The wingspan is about . The forewings are ochreous white with black markings: three spots on the basal portion of the costa, the middle one transverse and reaching halfway across the wing, a narrow irregular fascia at one-fourth with the posterior edge acute prominent in the disc and a small round spot beneath the fold before the middle. There is an irregular oblique blotch from the costa before the middle connected in the disc with a moderate irregular fascia from four-fifths of the costa to near the dorsum at three-fourths, dilated on the costa and touching a round spot towards the termen above the middle. There is also a dot beneath the costa beyond the middle and a round spot above the tornus, as well as a marginal series of marks or dots around the apex and termen. The hindwings are light grey, thinly scaled anteriorly, darker towards the termen.[2]
