760 MAJOR MARSHALL ON ASIATIC BUTTERFLIES. [Dec. 19, 
lar, well-defined black patch on the discocellular nervules; the sub- 
costal nervure to end of cell, the median and the base ofits 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. Uprerstde as inthe male, but with the black markings 
more developed: fore wing with the patch on the discocellulars as 
on underside of male, and a broad submearginal 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. UNpbeErRsrpe 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 neryure narrowly defined with black, the markings of 
the underside showing through by transparency. Unpersip—e— 
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
