into the hind ones, leaving only the yellow imder surfaces of the 

 latter and apices of the former exposed. The only plant the larvse 

 have been bred upon is Gratceva religiosa belonging to the botanical 

 family Gapparidce. The distribution of the butterfly has been 

 given above both for /lippo and the form taprohana. 



104. *Appias indra. — Wet-season brood. — Male, upperside : white. Fore- 

 wing : base and basal half of costa thickly irrorated with black scales ; a 

 minute, black spot on the discocellulars ; the apical half of the costa, and 

 the fcermen above vein 2, broadly black ; the inner margin of the black 

 colour broadly produced inwards in interspace 3 ; three obliquely-placed 

 spots of the groiind-colour on the apical area. Hindwing : uniform white 

 with a minute black speck on the discocellulars. Underside, fore wing : 

 white ; costa at base pea-green ; beyond with a broad black stripe that 

 curves round and crosses the wing postdiscally to the terminal margin 

 above vein 2 ; this black band produced prominently inwards in inter- 

 space 3 ; apex of wing beyond the black band yellowish, obscurely dusted 

 with black scales. Hindwing pale yellow, with very obsctire postdiscal 

 patches of white ; the whole wing irrorated somewhat sparsely with minute 

 black scales ; discocellular, 1st black spot more or less conspicuous. — 

 Female upperside: white. Fore wing : basal area up to nearly the apex of 

 the cell densely irrorated with blackish scales ; remainder of the wing 

 black except lower apex of cell, basal two-thirds of interspace 2 and 

 basal third of interspace 3, which are white : apex of wing with two ( not 

 three as in male) obliquely-placed, white spots. Hindwing : dusky black, 

 fading inwardly on basal half of wing to diffuse, dusky grey ; two or more 

 upper subterminal, white spots. Underside : similar to that of the male. 

 Forewing : the yellowish green colour at base more extended ; the curved 

 black band that crosses the wing very much broader and produced inwards 

 along the dorsum for a short distance ; apical area greenish yellow, with an 

 obscure series of pearly-white patches between it and the black band, a 

 similar short streak on the tornus. Hindwing differs from that of the male 

 in the deeper yellow of the ground-colour, which, however is similarly 

 irrorated with black scales and bars ; a conspicuous subterminal series 

 of pearly-white patches. An intermediate form of the female is common, 

 in which the black area on both fore and hindwing is reduced, to a simple 

 terminal edging that spreads diffusely inwards and obscurely encloses a 

 subterminal series of white, diamond-shaped spots. Antennte in both 

 sexes black, checkered with white spots ; head and thorax with, bluish- 

 grey hairs ; abdomen black with sparse white scaling ; beneath : head, 

 thorax and abdomen white. 



Dry-season bi'ood.-^-Wale upperside ; similar to specimens of the wet-season 

 form, but the black colour on costa, apex and termen very much reduced in 

 extent. Underside : the black, curved band on forewing very short, often 

 diffuse and obscure ; apex of fore and entire hindwing light earthy brown, 

 more or less densely irrorated with black scales that on the hindwing 

 run together in places and form ill-defined, zigzag markings. — Female 

 zipperside ; similar to that of the male the black on forewing of somewhat 

 greater extent ; termen of hindwing obscurely irrorated with black scales. 

 Underside : similar to that of the male ,- the oblique, black band on forewing 

 broader. Antennae in both sexes dark brown ; head with ochraceous-brown, 

 thorax with bluish-grey, hairs ; abdomen blackish ; beneath : head, thorax 

 and abdomen white. Expanse 54 — 74 mm.
