3Iah\ Upperside white. Anterior wings with tlie costal margin very 

 narrowly black to two-thirds from the base, the apical third black, the 

 l)lack area extending obliquely from the costal margin, a little Ijeyond the end 

 of the cell, to the outer angle, its inner edge being dusted with white scales. 

 Posterior wings white, with the outer margin from a little below the first subcostal 

 ncrvule to the anal angle narrowly black, rather more widely black in the 

 middle, the inner edge of the black area dusted with white scales. 



Underside. Anterior wings with the costal margin more broadly black 

 than on the upperside to the end of tlie cell ; thence the black area covers the 

 apical area obliquely to the outer angle ; a little before the a])ex are three 

 yellow spots placed obliquely between the veins, the middle spot the smallest, 

 the lowest spot the largest ; the cell and the rest of the discal area white. 

 Posterior wings black, with the basal space above the costal nervure yellow ; a 

 narrow yellow streak on the margin above the first subcostal nervule at the 

 apex, and an oblong yellow spot below it, a little before the margin. 



Finnidc. Like the male, but on the upperside the black area on both wings 

 is more extended, and on the underside the yellow spots are rather larger.

Jilalc. Upperside lacteous white. Anterior wings with the apex and outer

 apical third of the wings, but not extending beyond the lowest median nervule. 

 Except within the dark apical space and on the costa, the veins are white.
