 Legs yellow-whitish, banded with dark fuscous. Forewings yellow-whitish, 

 with numerous obscure fuscous or brownish-ochreous transverse strigee, 

 sometimes nearly obsolete, in other specimens nearly concealing ground-

 blackish-fuscous spot on costa before f , reaching -§• across whig, connected 

 at apex with a sometimes obsolete dark fuscous transverse mark in disc ; a 

 short interrupted dark fuscous longitudinal streak in disc beyond middle ; a 

 blackish dot on inner margin at ■§- ; a small elongate dark fuscous spot on 

 costa a little before apex, followed by a tolerably distinct irregular yellow- 

 whitish line not reaching inner margin : cilia yellow-whitish, often suffused 

 with pale ochreous, with a blackish interrupted basal line. Hindwings 

 rather dark reddish-grey ; cilia grey, on hindmargin with a partially obsolete
