also comparatively narrower and with more slender intervening black 

 veins ; the marginal row of spots is broader, and the intervening trans-

Papilio sikkimensis, n. sp. 



Differs from N". W. Himalayan and Nepalese specimens of P. asiati- 

 cus in the very much darker black colour of the upperside ; and in the 

 fore wing having the yellow cell-bands quadrate in form, the discal band 

 composed of smaller and shorter portions, and the area intervening be- 

 tween the band and the marginal spots broader. On the hindwing, the 

 veins are broadly black-lined, the abdominal border also black and leav- 

 ing but a small subanal lunule ; the discal margin of the yellow area 

 has a more regularly scalloped edge, and there is also a broader discal 

 area intervening between it and the marginal spots ; the crimson anal 

 lobe-spot is smaller, narrower, and has a lower retort-like black spot. 



Expanse 2f to 3| inches.

Cupitha, n. g. 



Male. Forewing elongated, triangular, costa arched at the base, 

 exterior margin oblique, posterior margin convex towards the base ; first 

 subcostal emitted at nearly one-half before end of the cell, the branches 

 at equal distance apart ; cell extending to nearly two-thirds length of 

 the wing ; discocellular almost erect, slightly bent close to upper end 

 and below the middle ; upper radial from the angle near subcostal, lower 

 radial from the angle below the middle ; the middle median at one-sixth, 

 and lower median at four- sixths before end of the cell, submedian undu- 

 lated ; on the underside of the forewing is a short, broad, nacreous patch 

 on the middle of posterior margin, across which the submedian is lined 

 with rough scales, and from near the base of the margin projects a broad 

 pencil of long rigid hairs : hindwing short, costa very much arched from 

 the base, apex rounded ; costal vein extending to near apex, forked at 

 its base ; subcostal bent upward and slightly joined to costal close to the 

 base, subcostal two-branched, first branch from close to end of the cell ;
