760 MAJOR MARSHALL ON ASIATIC BUTTERFLIES. [DcC. 19, 



lar, well-defined black patch on the discocellular nervules ; the sub- 

 costal nervure to end of cell, the median and the base of its branches 

 and the submedian at its base broadly bordered with grey irrorations, 

 the remaining nervules narrowly bordered in the same way. Hind 

 wing white, with the blackish irrorations of the upperside obsolete 

 on the margin, but much blacker round the cell and at the base of 

 the submedian and internal nervures ; a marginal series of bright 

 yellow spots on a pure white ground, one between each pair of ner- 

 vules, and decreasing from the apex ; a discal series outside the cell, 

 elongate between the median nervules ; a patch at the base, another 

 almost filling the cell, and the entire inner margin broadly, bright 

 yellow. 



Female. Upperside as in the male, but with the black markings 

 more developed : fore wing with the patch on the discocellulars as 

 on underside of male, and a broad submarginal irrorated black band, 

 outwardly dentate and sharply defined, inwardly diffused. Hind wing 

 with a broad irrorated blackish patch round end of cell, and a dif- 

 fused submarginal band from the costa disappearing below the 

 second median nervule in some specimens, in others continued to 

 the lower median nervule as an irrorated blackish border bearing 

 white marginal spots ; the yellow patch at anal angle fainter and 

 more diffused; otherwise as in the male. Underside as in the 

 male, but with the black mark on the discocellulars larger, especially 

 on the hind wing, and both wings with the irrorated blackish sub- 

 marginal band, but much less wide than on the upperside. 



Closely allied to D. sanaca, Moore, Cat. Lep. E. I. C. p. 79, but 

 differing in having all the black markings greatly reduced and paler, 

 and many of them altogether wanting, especially on the hind wing. 

 The female is not nearly so black an insect as male D. sanaca ; while 

 the male is conspicuously white, with a few black markings ; the 

 yellow marginal spots on the underside of the hind wing being on a 

 pure white ground is a very distinctive character. Expanse 3"3 to 

 3*5 inches. 



Habitat. Kunawar in the N.W. Himalayas. The type specimens 

 are in the collection of Col. A. M. Lang, R.E., where they have for 

 many years stood under the above name : but no description of them 

 has hitherto been published. 



Aporia belucha, n. sp. 



Upperside white : fore wing with the nervules black, a black patch 

 at end of the cell on the discocellulars, the outer margin broadly 

 black, terminating abruptly at the lower median nervule, and bearing 

 a series of irregular white marginal spots ; these spots in some 

 specimens extend to the margin, leaving only a conspicuous sub- 

 marginal dark band. Hind wing with the outer margin and outer 

 half of each nervure narrowly defined with black, the markings of 

 the underside showing through by transparency. Underside — 

 fore wing as on upperside, but with the costa, apex, and outer 

 margin suffused with pale yellow ; hind wing pale yellow, all the 

 nervures broadly and evenly defined with black, and a submarginal
