Antennae black with minute white specks ; the long hairs on head and thorax greenish-grey; abdomen black ; beneath : head, thorax and abdomen white.
Female has the underside similar to that of the male but the scattering of black scales more prominent, the black on the apex and termen of the fore wing and the black spots on the termen of the hind wing broader, more extended inwards; on the fore wing there is an additional spot in interspace 1, and both this and the spot in interspace 3 in many specimens are connected by a line of black scales along the veins to the outer black border ; also the spot in interspace 1 often extends across vein 1 into the interspace below.
