Underside dusky brown, purpures- cent black in cell of fore wing; the white markings as on the upperside but tinged with blue, on the hind wing not so well denned ; the discal streaks shorter; the postdiscal series of spots small, the subterminal series of spots somewhat cone-shaped.

Fore wing: the streak at base of cell broken, forming two elon- gate narrow spots, the spot in interspace 4 of the postdiscal series conspicuously out of line with the rest. Hind wing: the white in the discoidal cell reduced to two short streaks. On both fore and hind wings the spots of the subterminal series more or less hastate in shape with the points directed inwards. Underside : ground-colour as in P. lisarda, the streaks and spots of whit
