Forewings with sliglit excision bctwreu veins 4 iiiid 7, stronger in tlie ?; 

 hindmargin of bindwings angled at vein 4. 



The difference between the sexes is at first sight striking ; due chiefly to the 

 fact that the onter line is much farther from the margin in the ? , the marginal area 

 being not only darker but wider.

Forewings : white, striated with dull greyish brown ; the lines brown, starting 

 from costa as dark brown outwardly oblique streaks at one-fourth, one-half, and 

 two-thirds respectively ; the first bent in cell, the second bluntly angled below 

 vein 0, the third sharply angled above vein 6 and there distinctly marked with 

 black, all three then inwardly oblique to inner margin, the first to near base, the 

 second, somewhat waved, to its middle, the third to two-thirds ; below the middle 

 the second jijjpears double, a dark line of the underside showing through ; sub- 

 marginal line deutate-lunulate, from before apex to anal angle ; the space between 

 third line and submarginal filled up with brown and forming a band ; a patch of 

 brown at apex along costa, and a larger one on hindmargin beyond cell ; marginal 

 line blackish, swollen between the veins ; fringe whitish, chequered with fuscous ; 

 the veins pale across the darker tints ; cell-spot linear, dark ; space between second 

 and outer line whiter than rest of wing. Hindmargin excised between veins 4 and 7.

 two-thirds of costa, angled on vein 6, then oblique and slightly bent to middle of 

 inner margin ; median shade visible only above inner margin close to outer line ; 

 submarginal line only indicated at costa and inner margin by brown lunules pre- 

 ceding it, these at costa edged with paler, and at inner margin forming a zigzag 

 mark edged with brown ; a slight brownish cloud on costa before apex and on 

 hindmargin below it ; fringe pale brown, darker just below apex.
