the apex are two rather large white patches, witli an iiulica- 

 tion of a smaller patch above and another below them. Pos- 

 terior wings with a marginal black band extending from the 

 anal angle to the lowest subcostal nervule. 



Underside. Anterior wings white, with the costal and 

 apical areas more broadlj black ; in the black apical area 

 are situate five spots, of which the three uppermost are yellow, 

 the two nearest the costa are oval, the second being the largest, 

 the third is more conical, the two lowest spots are nearer the 

 margin and whiter and smaller. Posterior wings bright yellow, 

 inclining to orange towards the anal angle, with the marginal 

 black band wider than on the upperside, in which are situate 

 five yellow subconical spots, the spot nearest the anal angle 

 almost obsolete and the spot nearest the apex merging into 

 the yellow area. 



Female. — Upjjerside. Both wings white, with the black 

 costal and marginal bands much wider than in the male, and 

 on the anterior wings extending broadly along the outer 

 margin to the inner margin at about one fourth from the 

 outer angle; the white subapical patches on the anterior 

 wings as in the male. 



Underside nearly as in the male, but all the spots are 

 yellow, with an additional spot in the black apical area of the 

 anterior wings, and on the posterior wings the yellow area 

 is shaded with white and tiie yellow spots are larger and more 

 conical. 



Expanse of wings 2^ inches.

Jifale. — Ujyperside does not differ from D. ladas, Grose 

 Smith. 



Underside. Anterior wings differ from those of D. ladas in 

 the black area being more extended, only the basal two thirds 

 of the cell and the space below it to the inner margin being 

 white, the white area extending obliquely over the lower part 

 of the disk, but ceasing on the iinier margin before the outer 

 angle. Posterior wings black, witli the basal third densely 

 irrorated with yellow scales from the costal margin at one third 

 from the base, thence transversely across the cell to the inner 

 margin a little above the anal angle ; the yellow subapical
