fuscous ; a fuscous discal spot ; a fine waved fuscous' line from 

 <josta beyond middle to innermargin beyond middle, sharply 

 indented in middle and becoming edged with whitish towards 

 innermargin ; a double black spot near anal angle ; a narrow 

 silvery-white mark below ; line along termen as in f ore^vings : 

 cilia dark fuscous, temiinal half grey, division distinct. 



Very closely allied to partitaria, Walk., but differs by the
