Wet-season Brood (Figs. 1 <£, la, ?, lb, £). 
Imago. —Male. Upperside of a nearly uniform blackish-brown colour. Forewing 
with an obscure discal band of small whitish spots, one or two obliquely, beyond the 
cell and two below them nearer the margin, these spots mostly suffused with scales 
of the ground colour, sometimes nearly obsolete. Hindwing without markings, cilia 
white. Underside, pale pinkish-grey. Forewing with an obscure and irregular 
whitish patch on the lower half of the disc, three spots in the cell, caused by six 
whitish lines crossing it, a similar spot below the middle of the cell, some similar but 
smaller sub-costal spots, four joined together from the costa near the apex, three below 
them, and a series of sub-terminal brown spots. Hindwing with basal, sub-basal and 
medial bands of spots, similar to those on the forewing, a discal band of similar spots 
joined together, and a sub terminal angulated brown line. 
Female. Above and below similar to the male, but the band on the forewing 
above is better pronounced, and the spots larger, but often much suffused.
