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 suifused. 



Expanse of wings, $ ^ l\ inches. 



Dry-season Brood (Figs. Ic, ^, Id, ?, le, ?). 

 Male. Much paler than the Wet form, the band is broad and continuous from 

 near the costa of forewing, outwards almost joining the two lower spots, the portion of
