<$ , Upperside : white ; base of both wings and costa of fore wing 

 for a short distance sparsely irrorated with black scales. Fore 

 wing sometimes narrowly, sometimes broadly black ; a round black 

 spot in the middle of interspace 3. Hind wing uniform with only 

 a very short, transverse, laterally compressed, and generally diffuse 

 black spot in interspace 7 that crosses vein 7 to the costa. Under- 

 side : ground-colour similar. Pore wing : upper half of cell and 

 costal margin above it sparsely irrorated with black scales ; apex 

 faintly shaded with ochraceous or cream colour ; a black spot in 

 interspace 3 as on the upperside and another in line with it below 

 in interspace 1. Hind wing : dorsal margin somewhat broadly 

 white, remainder of wing cream-colour ; base and cell sparsely 

 irrorated with black scales. Antennae, head, thorax and abdomen 

 black checkered with white scales and a little whitish pubescence 

 on the head and thorax ; beneath : head, thorax and abdomen white. 

 $ . Similar to the tf , but in fresh specimens on the upperside the
