end of the cell, a rather broad apical black band gradually narrowing hindward to the 
lower angle, with three large spots of the ground colour in it in a row, sometimes there 
is a minute spot above and another below this row, and some pale dots on the margin, 
some grey scales at the base. Hmdwing with a band of largish square spots on the

tinged with salmon colour, a large black oval white-centred spot at the end of the cell 
of the forewing, a red-brown, white-centred cell spot on hindwing, and a discal band of 
red-brown spots across both wings. 
Female above and below marked like the male, the spots a little larger, the ground 
colour nearly always white, every example in the B. M. collection is pure white, and in 
most examples there are indications of a discal band of black spots on the hind wings 
above; on the underside the edges of the wings are tinged with pink, the spots large 
and dark, nearly black on the forewing.

Dry-season Brood (Figs. 2c, 2d, $, 2e, $). 
Male. Upperside paler than in the other form. Forewing , with the irrorations of 
the costa and at the base very feeble, the cell spot smaller, the apical band paler in

indicated, there being merely three or four faint marks on it. Underside very pale, the 
markings the same, but very feeble and of a pinkish-ochreous colour. 
Female. Often white like the Wet-season form, sometimes tinged with salmon
