232 LEPIDOPTERA IXDIC'A. 



and extreme Westei'n Asia sliould have shown sucli great sexual divergence in 

 coloration and markings. There are two other points which I may mention. One 

 is the curious fact that A. JSHphe does not exist, apparently, in Southern Burma and 

 the Malay Peninsula, though it is found to the Xorth in Upper Burma, and to the 

 South in Sumatra. The other point, is the presence in the males of both forms 

 (typical Nixihe and Gastetsi) occurring in South India, on the upperside of the fore- 

 wing, of raised modified scales (androconia) along a jjortion of the first median 

 nervule. This feature is, moreover, absent from Ceylon specimens, which is again, 

 an extraordinary fact, Ceylon being so close to India, divided from it only by a narrow 

 shallow strait. I may also note that were sufficient material available from South India, 

 it would probably be found that typical i\^t////e and Gastdsi merge into one another, as 

 I possess a female of the former from the Nilgiri Hills, which have the purple area 

 indistinct and the white bar narrow of the forewing on the upperside, showing by the 

 partial obsolescence of these especial features a distinct approach to the ancestral 

 form, as I am inclined to believe .1. Gastetsi and A. inconstant to be" (Journ. Bombay 

 i;. H. Soc. 181)3, 153).
