6 ? White, antennas and palpi black, a thin reddish band behind 

 the head and another in front of thorax which has some brown 

 longitudinal streaks, abdomen scarlet, with black bands, and a row 

 of black spots on each side, and with some thickly disposed white 

 hairs covering the base, wings white. Fore-wings with the costa 

 and veins broadly brown, in some male specimens the vein streaks 

 are so broadly brown as to make the wings look brown with white 

 interspaces, the costal line is inwardly bordered with scarlet, and the 

 brown on the median veinlets thicken into spots forming a discal 

 row, sub-median vein white, on a brown band which fills nearly half 

 the interspace above and all the space below it. 



Hind- wings white with a large brown discal spot and a brown 

 marginal continuous band, which runs in a paler form up the abdo- 

 minal margin. 



Underside, white, face scarlet, abdomen with two rows of black 

 spots ; wings white, costa of fore-wings scarlet, both wings with 

 a large brown spot at end of cells, fore-wings with brown streaks on 

 the outer margin, hind-wings with brown bands ; legs streaked with 

 scarlet, tarsi black, with white marks.

 running parallel with outer margin which has a similar row, and 

 between them three more black spots, 1st on costa, 2nd above, and 

 3rd below the middle. 



Hind-wings more ochreous than fore-wings, a large black discal 

 spot and a black marginal band, divided in the sub-median inter-
