The distal iiiarj^nnal area of tlie fonjwiiig is generally limited hy a curved line 

 rnnning from apex to hinder angle ; this line, which we call postdisco-submarginal, 

 is comfiosed of a siibmarginal line and a ])ostdiseal one joining each other ; the free 

 costal jioi'tion of the postdiscal line is often vestigial. 



Key to the species : 



It. Forewing, above, with a white .submarginal 

 line forming a right angle with an 

 oblique white line crossing wing from 

 middle of costal margin to hinder angle . 



Forewing with a black band from middle 

 of costal margin to hinder angle ; 

 abdomen without black side-patches 



Abtlomen with \)lack side-patches 

 h. Forewing with a white curved discal and 

 a white antemediau band, converging 

 posteriorly ; stigma large, triangular 



Forewing with a straight discal band which 

 is at right angles to liinder margin 



Forewing without that band 

 c. The band edged witli white ])roximally, 

 4 mm. from lower angle of cell 



The band edged with white i^roximally, 

 at least 6 mm. from lower angle of cell . 



The band not edged with white proximally; 

 stigma consisting of several dots . 

 (I. A large triangular brown discal area on 

 forewing, inner edge oblique, outer edge 

 sharply marked, quite straight from R- to 

 hinder margin of wing, stigma V-shaped 



A blackish band across wing from middle 

 of costa to distal margin before angle, 

 space between this band and distal 

 margin blackish, excepting patches in 

 costal area, contrasting sharj)ly with 

 middle area of wing ; no stigma 



Forewing not so ; with or without stigma . 

 e. Postdisco-snbmarginal line straight from 

 R^ backwards, sharply marked 



Postdisco-submarginal line obviously den- 

 tate; irregular, often very feebly marked 



Forewing with sharply defined clayish patch 

 in middle of hinder margin .
