Males are white, the forewings with a black marginal border, which is broad on the costa, narrowing posteriorly to the submedian fold and continued as a line to the submedian or below it. The edge of this black area is straight from the costa to cellule 4, curved inwards over vein 4, and is then oblique to the margin. There are generally two submarginal dots, but sometimes more. There is some black basal dusting. The hindwings have a narrow grey-black marginal border from the anal angle to vein 4 or a little beyond, sometimes slightly broken up by the white ground-colour.
Females are creamy-white, the forewings with brownish basal suffusion and a broad black-brown outer marginal border shaped as in the males. The costal area beyond the middle is black-brown and at the middle only the edge is darkened. There is also a narrow black-brown discocellular bar joined to the costal area. The edge of the marginal area from vein 4 to the inner margin is toothed at the veins. The hindwings have a black-brown marginal border.
