COLIINM. 163 



the end of cell ; antennae and legs rosy ; palpi greenish-yellow ; head with frontal tuft ; 

 thorax and abdomen greenish-grey ; forepart of thorax rosy. 



Female. Very similar to the male. Upperside with the ground colour richer. 

 Foreiving with the black band on the exterior margin broader. Hinchcing with the 

 dusky irrorations more dense. Underside much as in the male. 



Expanse, ^ ? 2 inches. 



Habitat. — Thibet ; Cashmir. 



Distribution. — In the B. M. from Ladak, Koka, Lahul, Cashmir, and many 

 examples from Eastern Thibet. Flies with rapidity over the pastures on the mountain 

 slopes above the Sutlej, near Shipkee, at an altitude of thirteen thousand to fifteen 

 thousand feet, frequenting the meadow-land, rich in grasses and flowers, just below 

 the melting snow-beds in June (Lang), also taken at Ladakh and Cashmir. 



Note. — Moore's Colias Shipkee was published in October, 1865, Felder's descrip- 

 tion as well as his Plate 27 were not published till some time after that date ; the 

 dates on Felder's plates are the dates on which the proofs were completed, and seldom 

 represent the date of publication. Dr. A. G. Butler has commented on this in Ann. 

 Mag. Nat. Hist. 1870, p. 2.

Imago. — Male. Upperside pale sulphur-yellow, nearly white. Forewiny with the 

 base, costal space and veins irrorated with black scales, a large, nearly oval black spot 

 closing the cell, a broad black band, occupying the outer third of the wing, broadest at 

 the apex, its inner margin recurved and irregular, a complete series of spear-shaped 

 large spots of the ground colour through the middle of the band, one in each interspace, 

 the first and third from the lower angle the smallest. Hindwing with some basal black 

 irrorations, a large pale spot at the end of the cell, an apical black band, rather broad, 

 almost filled with four large spear-shaped spots of the ground colour and not extending 

 further hindwards. Underside whiter. Foreioing with a large black spot at the end of 

 the cell, costal line orange, the veins prominent, the outer band space limited by a 

 discal row of black spots, the lowest large, decreasing in size upwards and becoming 

 obsolescent. Hindwing with a marginal band of faintly indicated large spear-shaped 

 spots, on a pale ground, the remainder of the wing densely irrorated with greenish- 

 grey scales, a large round white spot at the end of the cell.
