 white ; a fuscous dot on base of costa ; a strongly curved band of 

 irregular fuscous mottling, proceeding from a blotch of dark fuscous 

 markings on dorsum at ^, through disc above middle, and returning 

 to dorsum at | ; an oblique fuscous shade terminating in tornus 

 not reaching costa, and another along upper part of termen : cilia 

 white, round apex with fuscous basal shade (imperfect). Hind- 

 wings white ; costa expanded from base to |, with broad projection 

 of long rough scales suffused with grey beneath, and long white

 base, towards tornus also suffused with rather dark fuscous; two small 

 rather dark fuscous spots transversely placed at end of cell; a rather 

 irregular curved cloudy fuscous line from costa beyond middle to end 

 of dorsal streak, sometimes obsolete on costa ; a somewhat oblique 

 straight fuscous shade terminating in tornus, not reaching costa ; a 

 cloudy fuscous spot on upper half of termen : cilia whitish, base 

 tinged with fuscous. Hindwings fuscous-whitish or whitish- 

 fuscous, suffused with fuscous posteriorly ; costa rather expanded
