cJ. Forewinq : broad; hindmargiu somewhat protuberant below middle and

Himlwiiiq : narrow, almonil-shaped ; iuner margin short ; hindmargiu from 

 anal angle to vein 2 straigiit, thence rounded. Costal half above uncolonred, with 

 an oval patch of mealy scales beyoud upper end of cell, corresponding with a similar

 and two-thirds of inner margin ; submarginal line pale, waved, preceded on costa 

 by a black blotch and beyoud cell by two black lunides; marginal line black, 

 interrupted, most distinct at the indentation above anal angle ; fringe green,

llindwinq : with two curved dark lines forming central fascia, the outer 

 double and projectiug at middle ; submarginal line obscure, indicated by two green 

 shades ; a black marginal lunide before anal angle ; in i the lines are wanting ;
