 the basal area only dark green in both sexes ; the lines blacki.sh, ]ilaiu only 

 in the ?, more or less obscured by the darker tints in the cf ; first, obliquely 

 concave, from one-fifth of costa to one-third of inner margin, angled outwards 

 on subcostal vein, on snbmedian fold, and above inner margin below submediau 

 vein, the last angle acute ; a diffuse median shade from about one-third of costa, 

 at first oblique outwards, more or less obsolete across vring, but ending in an 

 oblique black mark on middle of inner margin, shortly beyond first line ; it is 

 sometimes indicated by a dark mark between median vein and snbmedian fold 

 beneath the origin of vein 2 ; onter line from just beyond middle of costa, oblique 

 outwards to vein 4, then luuulate-dentate inwards to inner margin just beyond 

 median line, between veins 2 and 4 generally obliterated ; submarginal line pale, 

 bluish white, more distinct in <S than ? , dentate towards costa and waved below, 

 preceded by a darker shade, especially at costa, and followed by a dark spot before 

 anal angle ; a row of black marginal lunules ; fringe greenish grey or rufous grey ;

Underside rufous ochreous, thickly black-speckled ; an oblique diffuse broad 

 median band ; a broad black submarginal fascia from below costa to anal angle, 

 followed by a square white marginal blotch from vein 3 to above vein 4 ; in the

 is an antemedian black mark on costa. 



Head and thorax dark green, in ? mixed with reddish grey; abdomen
