COMMON BUTTERFLIES OF THE PLAINS OF INDIA. 339 



Race narendra, Moore. — A slightly differentiated and more or less local 

 form, notwithstanding that a few specimens from Assam, which should 

 properly belong to A. indra, more closely resemble typical narendra from 

 South India and Ceylon. 



Wet-season brood. — Male, iqjperside : differs chiefly from that of male indra 

 in the hindwing, which is bordered narrowly with black along the termen. 

 Underside : as in indra, but the yellow colour more vivid and the black, 

 bisinuate band that crosses the forewiug notably broader. — Female. 

 Differs from female indra on the upperside in the restriction of the black 

 colour, which has also its inner margin more clearly defined. No female 

 narendra (according to Colonel Bingham) is ever so dark above as the 

 extreme rain-season form of female indra. Underside : similar to the under- 

 side in i7idra female, but more closely sprinkled with black scales on the 

 hindwing. 



Dry-season brood. — The difference between the seasonal forms is less 

 marked than in A. indra. — Male, upperside : differs in the hindwing which 

 is always margined along the termen, though often very narrowly, with 

 black ; his colour also extends shortly in a few lines along the veins. 

 Underside : as in A. indra, but the shade of brown on apex of forewing and 

 over the whole of the hindwing is darker, the irroration of black scales 

 more dense, the black, bisinuate band that crosses the wing broader. — 

 Female upperside : differs from the wet-season from only in the width of the 

 black on the terminal margin of the hindwing, which band is about half as 

 wide as in rainy-season specimens. Underside : similar to the underside in 

 female of the wet-season form. Expanse 68-70 mm. 



Neither Aiypias indra nor this race narendra have been bred as 

 far as is known. The former is distributed over "the Himalayas, 

 Nepal, Sikhim, Bhutan, Lower Bengal, Assam, Burma, Tenasse- 

 rim, extending to the Malay Peninsula, Cochin China and China." 

 Narendra is confined to Southern India, Ceylon and Assam. 

 It is extremely doubtful whether it exists in the Bombay Presidency 

 at all. 



105. Appias albina. — Wet-season brood:- — Male, upperside: pure chalk 

 white. Forewing costa, apex and termen irrorated, not very densely, 

 with black scales ; this irroration narrowed on termen posteriorly and 

 not extended to tornus. Hindwing : a much lighter irroration of black 

 scales along posterior portion of termen. Underside: apex of forewing 

 and the whole surface of hindwing pale, dull ochraceous, sometimes 

 with a faint pinkish tint, never pale yellow. Female dimorphic ; 1st 

 form upperside forewing : white, irrorated at base and up to as far as 

 two-thirds of the cell with blackish scales which give that part a bluish- 

 grey appearance ; costa broadly and apical half of the wing jet-black ; 

 the inner margin of this black area is irregularly curved, extended 

 inwards and forms a right angle on vein 3 ; thence the black area is 

 diffuse and bounded by a straight line terminating on the dorsal margin 

 jvist before tornal angle and has three, rarely four, yellowish spots, 

 .placed in an outward curve preapically up on it. Hindwing : pale 

 yellow, the terminal margin broadly black, this colour extended triangular- 

 ly up the veins for a short distance ; base and interspaces 1, 2, irrorated 

 with black scales. Underside forewing: as on the upperside but the 

 apex a beautiful, nacreous, bluish white ; the oblique curved, black band 

 not broad, its outer margin irregularly zigzag, never evenly curved. 

 Hindwing : the whole surface the some beautiful nacreous, bluish white as 

 the apex of the forewing.
