The base of the fore wing and the basal portion of the costa, and base and upper margin of cell with a scattering of black scales; apex and terminal margin to about the middle, decreasingly, black, on the latter the black extended for n very short distance triangularly along the veins ; a round black spot in interspace 3. The hindwing has a subcostal black spot as in Pieris rapae but is generally larger and more conspicuous, and a series of four or five terminal black spots that vary in size at the apices of the veins.
Underside : fore wing white ; cell and costa lightly irrorated with black scales; apex somewhat broadly tinged with ochraceous yellow; interspaces 1, 3 and 5 with conspicuous subquadrate black spots, the spot in interspace 1 sometimes extended into interspace 1 a, that in 5 ill-defined. Hind wing : from pale, almost white, to dark ochraceous, thickly irrorated all over (with the exception of a longitudinal streak in the cell, and in the darker specimens similar longitudinal streaks in the interspaces) with black scales ; costa above vein 8 chrome-yellow. 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.
Has a wing expanse of 42–60 mm.
