146 LEPIDOPTEBA INDICA. 



distinct. Underside coloured as in the other form, but the bands and spots show much 

 more plainly through the wing. 



Female. Upperside paler than in the male, sometimes nearly white. Foreirnvj 

 generally with bright salmon-pink suffusion on the basal half, the costal band irrorated 

 with yellow scales, not extending beyond the end of the cell, except in a thin costal 

 line, all the spots on the outer border larger and complete, there being usually one in 

 each interspace. Hindwing as usual without the costal band, some salmon-pink 

 suffusion towards the base, but less than in the Forewing ; the exterior black band 

 broad and usually well formed, both rows of spots in it being complete. Underside 

 like that of the Wet-season form, but the outer marginal space in both wings is always 

 paler, and there is usually a very bright salmon-pink suffusion on the basal half of the 

 Forewing. 



Expanse, ^ ? 1^ to lf\j inches. 



Habitat.— North-Western India, Arabia. 



Distribution. — We have it from Karachi, where it is in great plenty ; w^e took 

 the Dry-season form in November and December, 1885, and January, 1886, and what 

 we call the Wet-season form in most of the other months of the year ; we have the 

 Wet form taken in Hydrabad in July, 1886, from Deesa in Eajputana in July, August, 

 September and October, in Ahmedabad in September, and we have it from Bhooj ; 

 Butler records it from Agra, Mynpuri, the Punjab and Kathiawar ; we also have many 

 examples of both forms taken by us at Aden.

Wet-season Brood (Figs, 1 $, la ?, lb ?). 



Imago. — Inhabits desert and sandy tracts. Male. Upperside bright salmon- 

 pink, much darker and brighter than in any of the preceding species, and more 

 uniform. Foi^eiving with very broad deep black borders, leaving but a little more than 

 the disc down to the lower margin salmon-pink, the basal fourth being densely 

 irrorated with black and blue-grey scales ; the costal band comes down to the sub-costal 

 vein, it fills nearly the upper half of the cell, and is joined to the large black spot at 

 the end of the cell, which usually closes it ; the apical portion of the outer band is
