RAHINDA. 345 



coalescent, forming an irregular oblique short broad band ; anterior 

 spots also coalescent, oblique from costa ; a postdiscal obscure grey 

 bicurved transverse line, and a very slender, also obscure, orange 

 transverse subterminal line. Hind wing: a subbasal transverse 

 broad band, and a much narrower postdiscal band curved inwards 

 at the ends ; beyond this the black terminal margin is traversed 

 by a still blacker subterminal line. Underside chestnut- brown, 

 covered with short, slender, transverse brown stria? on the margin 

 of the orange markings, which are similar to those on the up per side 

 but broader, paler, and less clearly defined. Fore wing : the pale 

 transverse postdiscal and orange subterminal lines of the upperside 

 replaced by a postdiscal lilacine narrow band, defined by somewhat 

 crenulate chestnut-brown lines on each side, and a pale subterminal 

 line. Hind wing : the base suffused with lilacine ; the subbasal 

 and postdiscal bands bordered outwardly by narrow lilacine bands, 

 the orange-yellow of the postdiscal band much obscured by the 

 transverse brown stria?; the terminal margin with a sinuous obscure 

 broad lilacine line. Antenna?, head, thorax and abdomen black ; 

 beneath, the palpi and thorax greyish, abdomen ochraceous. 



Dry -season form. — S $ . Similar to the wet-season form, but the 

 markings very much broader ; on the upperside of the fore wing 

 the postdiscal line generally and the subterminal line always 

 clearly defined, the former sometimes like the latter, orange- 

 yellow. Underside paler, the markings more blurred, the trans- 

 verse short brown stria? in many specimens covering nearly the 

 whole surface of the wings. 



Exp. s 2 38-54 mm. (1-5-2-13"). 



Hah. Continental India, from the Himalayas to Travancore ; 

 Assam ; Burma ; Tenasserim, extending into the Malayan Sub- 

 region. 



Larva. "Has two forms. In the first the head is large and 

 roughly triangular, the segments of the body increase to the 

 fourth and then diminish gradually, and the third, fourth, sixth 

 and twelfth have each two obtuse dorsal points. The fore part 

 from the fourth segment is generally inclined downwards at an 

 angle with the rest of the body and is with the underparts of 

 a dark greenish-brown colour. The rest is just that shade of 

 greenish-grey which the leaves assume when withered, and is 

 crossed by diagonal dark bands exactly representing the spaces 

 between the leaflets as a painter would paint them — a most perfect 

 disguise. The second form of the larva differs in having the head 

 furcate, while the dorsal points are replaced by long spine-like 

 processes. The figure will give a better idea of the difference than 



any description. The butterfly resulting from the larva 



with spines has a light male-mark ; that resulting from the other 



a dark male-mark The two forms of larva are never 



found together; the smooth type of caterpillar is often found 

 in quantities on one bush .... the smooth caterpillar feeds on 

 Acacia and Albizzia, the spined one has never been found on any 

 plant but Acacia.^ {Davidson, Bell § Aitlcen.')
