REVISION OF GENUS ZAMARADA 67 



84). In examples from the island of Borneo the dorsal process is identical with that 

 of the Javanese type, but the cornutus is similar to the form found among Sumatran 

 specimens. The female genitalia vary geographically in the form of the sterigma. 

 For the present no subspecific name is proposed, all specimens being treated as 

 baliata. 



Distribution. West Malaysia (Malaya), Singapore, Sumatra, Java, Borneo.

9 (PI. 100, fig. 893). Hyaline area of wings greyish yellow. Non-hyaline terminal third 

 buffy brown (pi. 4, B3, sand) ; subterminal fascia ill-defined, represented by a grey suffusion. 

 Underside of non-hyaline terminal area brown proximally, paler terminad. 



$ genitalia (PI. 19, figs 527, 528). Sterigma with three processes extending posteriorly; 

 medial process, from lamella postvaginalis, spatulate and broadly rounded at tip, almost 

 equal in length to the two lateral processes from the lamella antevaginalis, which are serrate 

 on their inner margins.
