358 Col. C. Swinhoe on new Indian Butterflies. 



divided by the veins into eight areas, the eighth area being a 

 small space at the upper end of the cell, just above the square 

 knob of the black inner margin ; costal border and basal area 

 irrorated with greenish grey. Hind wing with the base very 

 slightly suffused with grey, and with a marginal brownish- 

 black border about a quarter of an inch deep near the apex, 

 and attenuated hindwards until it becomes a mere marginal 

 line at the anal angle. 



Underside clear bright ochreous yellow : lower half of fore 

 wing paling to primrose-yellow ; a brown spot at the end of 

 each cell, large on the fore wing ; a suffused brownish mar- 

 ginal patch near hinder angle of fore wing : a brown patch on 

 thecostaat the apex of hind wing, and a discal (nearly sub- 

 marginal) row of brown spots across both wings, one in each 

 interspace, bent in on the costa of fore wing, the spots largest 

 on the upper half of hind wing, but otherwise of fairly uniform 

 size ; a black marginal point on each vein in both wings. 



$ . Differs from male above in its interior band limiting 

 the subapical ochreous-red area, being broken in the middle, 

 in the absence of the knob, and in the area being rather 

 narrower. 



The underside is dark chrome-yellow, paling to pale prim- 

 rose on the lower half of the fore wing, and all the spots 

 except the one at the end of the cell in the hind wing are large 

 and of nearly uniform size.

Andaman Islands. 



Allied to I. andamana, Moore ; is much yellower, the 

 ochreous-red patch in both sexes is deeper, and the black 

 bands very much narrower, and below the male is well spotted 

 on the hind wing, instead of being nearly immaculate, as in 

 I. andamana. 



8. Appias olferna, n. sp. 



$ . Upperside white. Fore wing with the costal and outer 

 marginal lines black ; costal area with grey irrorations for 

 two thirds of its length ; base also slightly irrorated with grey ; 

 apical patch formed of thick brownish-black bars on the veins, 

 as in A. zehmra, Cram., but shorter, paler, and more suffused, 

 lessening in length hindwards and inwardly confluent to the 

 second median branch ; an inwardly pointed large spot on the 

 first median branch and a very small one on the submedian 

 vein, sometimes absent. Hind wing with a marginal row of 

 small, faint, blackish-grey spots, one on each vein ; in one 

 specimen these spots are obsolete.
