Wet-season brood. rf . Upperside : pure white. Fore wing : 

 costa, apex and termen anteriorly very narrowly shaded with 

 dusky-black scales, the black colour produced very finely along 

 the veins for a short distance ; the rest of the veins white. 

 Underside : pure white, the black colour merely indicated along 

 the costa and at apex. $ . Upperside : white. Fore wing : costa, 

 the apex and termen very widely and the discoidal cell dusky 

 black, the black in the cell produced in a broad streak to the 

 black on the termen, so as to leave only a short oval oblique bar 

 of the ground-colour beyond the cell ; the black on the terminal 

 portion of the wing narrows posteriorly and has its inner margin 

 irregular ; on the posterior inner portion of the wing also there 

 is a somewhat diffuse dusky-black streak from base, narrowed out- 

 wardly and not extended to the black on the terminal margin. 

 Hind wing : terminal margin more or less broadly black ; a shading 

 of dusky-black scales that forms a diffuse subcostal streak from 

 base, and another more diffuse obscure streak across the disc 

 that leaves between it and the dark terminal margin a series of, 

 posteriorly, very ill-defined markings of the white ground-colour 

 which decrease in size up to interspace 6. Underside : white with 

 similar markings that are however, more diffuse. Fore wing : the 

 black along the terminal margin interrupted by a series of streaks 

 of the white ground-colour in the interspaces. Hind wing : the 

 black scaling along the terminal margin very faint, the dusky 

 shading on the basal and discal areas of the wing as on the upper- 

 side, but more or less obsolescent ; a faint tinge of yellow on the 

 humeral angle. Antennae in both sexes dusky black, obscurely 

 spotted with white ; head, thorax and abdomen above bluish white ; 

 beneath white. 



Dry-season brood. rf . Similar, but the narrow black markings 

 on the fore wing still more restricted. $ also similar but the
