210 PIEEIDJE. 



on the upperside the black area on apex and termen of fore wing 

 is not continued inwards along the dorsal margin, and the connect- 

 ing bar between the black in the cell and on the terinen is narrowed 

 by a triangular ernargination of its lower border at base of inter- 

 space 3 ; on the underside the black area on the termen does not 

 extend to the tornus, and the black area in the cell is separated 

 from that on the termen by the basal third of interspace 3, which 

 is entirely white. Hind wing : both upper and under sides are 

 precisely similar to those of Mage. Antenna, head, thorax and 

 abdomen as in A. lalaye. 



Exp. <$ 2 65-74 mm. (2-56-2-9").

The five next-described forms have been, and I fear still remain, 

 a standing puzzle to Indian Lepidopterists. Treating of a strictly 

 limited fauna, I personally think it very likely that all five are 

 mere varieties of one highly unstable form, not limited either to 

 locality or to season. In this work I have kept them apart simply 

 for convenience of description, for so far as I have studied the 

 material at my disposal, the differences in the five forms are not 

 only not of sufficient importance to constitute specific distinction, 

 but when long series are compared they break down, sometimes in 

 the male, sometimes in the female. 



With regard to this close similarity accompanied by variation I 

 have in the remarks succeeding the diagnosis of the family stated 

 what, in my opinion, is the chief causal factor and agent.

Wet-season brood. c? . Upperside : pure chalk- white. Fore 

 wing: costa, apex and terminal margin more or less densely 

 irrorated with black scales, this irroration narrowed on the termen 

 posteriorly and not extended to the tornus. Hind wing: a 

 much lighter dusting of black scales along dorsum, on tornus and 

 along posterior portion of termen. Underside : fore wing white, 

 apex broadly pale yellow. Hind wing : entirely pale yellow. $ . 

 Upperside : fore wing 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 it
