LEP ID OP TEE A INDIG A. 
Female. Upperside as in the females of the Dry-season form of Vestalis. Under¬ 
side similar as to markings, but the borders of the fore wing and the whole of the 
hindwing suffused with dark pinkish flesh colour, with minute irrorations as in the 
male, the flesh colour of the undersurface in both sexes fades in life, but not after 
death, and never becomes yellow as in Vestalis if the examples are kept from the 
light; a discal whorl of conjoined brown spots. 
Expanse, $ $ 1 t 5 q- inches. 
Dry-season Brood (Figs. 2d, J, 2e, $, 2f, J, 2g, $). 
Male. Upperside white, with all the bands very narrow, the white costal space on 
the forewing between the cell spot and the apical band much wider than in the Wet- 
season form, the white spots in the outer band larger, the marginal band of the hind¬ 
wing sometimes very narrow and seldom extending hindwards beyond the extremity of 
vein 2. Underside as in the Wet-season form. 
Female. Upperside white, often tinted with pale yellow, the bands as narrow as 
in the male, but much paler in colour, the basal half of the costa of forewing irrorated 
with ochreous scales. Underside like that of the Wet-season form, but the spots of the 
forewing are smaller, the lowest discal spot minute, and the hindwing has no markings. 
Expanse, J £ 1 T %- inches. 
Habitat. —Karachi (Sin d). 
Distribution. —We took this form at Karachi in November, December, January, 
February, and March, 1885-86. The type came from Karachi. We have never 
obtained it in any other locality. There can be no doubt there are two forms of it, 
whether we call them Wet and Dry-season forms or by any other term ; we have a 
long series, and cannot but come to the conclusion that it should be kept distinct until 
we get some good evidence to the contrary.

Insects of a uniform salmon-buff colour, with a black outer marginal band, 
occupying the apical third of Forewings and always extending to the lower angle, 
containing spots of the ground colour ; the band on the hindwings macular; males and 
females very similar, but many females liable to albinism; larger than Colotis, the 
costa of forewings concave, the apex sub-acuminate ; males always with a prominent 
sex mark on the forewings, in the form of a patch of brown specialized scales or 
androconia on the underside above vein 1, closer to the base than to the exterior 
margin, prominent above as a raised spot, the hinder margin of forewing prominently 
lobed ; all the species are desert forms. 
Type, M. Fausta , Olive, from Arabia and India.
