ino- to the fourth which is the largest, the two anal ones small and linear, 

 all outwardly defined with a fine gray line. Underside with the ground- 

 colour much paler than in the male, being almost white, all the marliings 

 larger and more prominent. 



The markings of the female of this species are so like those of 

 Niphanda tesselata, Moore (Proc. Zool. Soc. Lond., 1874, p. 572, pi. Ixvi, 

 fig. G) from Penang, that in the Journ. A. S. B., vol. li, pt. ii, p. 61, 

 (1882), I entered this species as occurring in Sikkim, with the remark : 

 — " One female at about 1,500 feet elevation. It is rather smaller than the 

 specimen described by Mr. Moore from Penang, and the upperside is en- 

 tirely uuglossed with blue," believing that the sex of the species describ- 

 ed by Mr. Moore was male, my specimens being undoubtedly females. 

 Having since obtained both sexes of my species I am able to describe it. It 

 does not agree with Mr. Moore's generic diagnosis of Niphanda, as N. ? 

 cymhia has only three median nervules to the forewing instead of four as 

 stated by Mr. Moore, the subcostal nervules being probably meant for 

 median; the first three subcostal nervules are all given off at regular inter- 

 vals before the apex of the cell, the fourth subcostal branching from the 

 third before its middle, and both reaching the costa before the apex of the 

 wing. 



It seems a fairly common species in the low valleys below Darjiling, 

 the females largely predominating in numbers, however, over the males.

Desckiptton : Male. Diff'ers from Horsfield's description on the 

 UPPEESIDK of the liindiving in that tlie cyaneous colour is placed broadly 

 on the outer margin, extending upwards towards the middle of the wing 

 between the third median nervule and subcostal nervure, not as stated by 

 Horsfield covering the hindwing " excepting the exterior and interior 

 borders." Hewitson's figure shows the hindwing entirely covered with the 

 blue colour. The foreiving is furnished on the underside with a bunch 

 of long black hairs attached to the inner margin near the base and folded 

 beneath. There is a corresponding cup-like depression on the underside of 

 the hindwing, which is marked on the upperside by a shining bare round 

 patch near the costal base of the wing and covered by the forewing. There 

 are fourteen male specimens in the Indian Museum, Calcutta, all taken by 

 Mr. A. Graham Young in the Kulu valley, and a single male from Sikkim,
