The hind wing above at the base blackish as far as vein 2, then with a broad median band about 5 mm. in breadth, at the inner margin and towards the base light yellow, distally orange-yellow, projecting almost rectangularly distad in cellule 4 (almost as in johnstoni) and adorned with black discal dots; the hindwing beneath light yellowish to the base with free black dots and beyond the middle with a broad blackish transverse band, which is separated from the distal margin by a fine light line; this light marginal line is broken up into small spots by the dark veins and the streaks on the internearal folds.
