1882.] ASIATIC BUTTERFLIES. 759 



It is possible that the two may be merely climatic variations of the 

 same species ; but until this is proved the name weranga cannot be 

 suppressed. Col. Lang's collection, containing the types of his 

 A. weranga, is now in my custody. 



Ypthima bolanica, n. sp. 



Upperside dark brown, distinctly glossed with purple in some 

 lights, as in Collerebia. Fore wing with a prominent black ocellus, 

 with two large bluish-silver pupils and narrow yellow iris, ringed 

 with dark brown, then with mottled greyish more broadly, and then 

 again with dark brown. Hind wing with one black ocellus very pro- 

 minently pupilled with bluish silver, and two bluish-silver specks 

 near anal angle, being the pupils of obsolete geminate ocelli, a sub- 

 marginal sinuous dark-brown line ; the margin of both wings nar- 

 rowly whitish, defined on the inside with dark brown ; the cilia 

 brown. Underside greyish white, covered more or less with fine 

 reddish-brown striae : fore wing with the ocellus as on upperside : 

 hind wing with six ocelli ; the first three in a line from the costa, 

 small, the third minute, the fourth between the first and second 

 median branches, large, the fifth and sixth geminated at the anal 

 angle, all prominently pupilled with bluish silver as on the upper- 

 side ; the cilia brown ; the margin of both wings pure white, in- 

 wardly defined by a brown line, then a whitish mottled line, broadest 

 at costa of fore wing and ending at the fifth ocellus of the hind 

 wing ; two brown lines, one on each side of the ocellus of the /ore 

 wing, and meeting below it continued on the hind wing as a single 

 narrow band, on which the first three ocelli are placed, and termi- 

 nating just beyond the third ; a short brown hne from the costa of 

 fore wing defined exteriorly with whitish, and again another brown 

 line continued across the hind wing to the abdominal margin, and 

 on the latter wing defined exteriorly with whitish. Expanse 1-6 

 inch. 



Taken by Lieut.-Col. C. Swinhoe (in whose collection the type 

 specimen is) at Mach in the Bolan Pass. 



Delias flavalba, n. sp. 



Male. Upperside white; costal and outer margins narrowly black : 

 fore wing with the nervules beyond the cell defined with black, and 

 all except the submedian nervure bordered on both sides with 

 blackish irrorations, most broadly along the discocellular nervules ; 

 the outer margin also with a border of blackish irrorations, broadest 

 at the apex. Hind wing with the nervures black, with a triangular 

 patch of blackish irrorations on the margin at the extremity of each 

 nervule, and with slight black irrorations along the median nervure, 

 the subcostal nervules and the space between them forming there an 

 indistinct bar ; a bright yellow patch filling the space between the 

 costal and subcostal nervures at the base of the wing, and a larger 

 patch of the same colour at the anal angle. Underside white : 

 fore wing with the outer margin black, broadly at the apex, where it 

 has three indistinct yellow spots at its inner edge ; a broad, irregu-
