 Neptis hordonia cnacalis Hewitson ; Evans, 1932 : 172. 



Seasonal forms, as always in the Andamans, are weakly differentiated ; in the 

 dry season form a yellow postdiscal band is more or less apparent on the upper 

 surface of the hind wing, but is obscured in the wet season form. The supposed 

 dry season form figured by Moore (1899 : pi. 301, figs 2d, 2e), and accepted as such 

 by later authors, is described below as a new subspecies of P. sandaka. Its recog- 

 nition as such was made possible by examination of the Ferrar coll. in BMNH, 

 which contained dated series of both species. 



Andaman Is.

Rahinda hordonia senthes Fruhstorfer, 1908a : 265. $$ Sumatra. Types Paris. 

 Rahinda hordonia senthes Fruhstorfer ; Fruhstorfer, 1913 : 597. 



The orange markings tend to be a little richer than in ssp. hordonia, but the 

 subspecies is of doubtful worth. 



Sumatra.
