Male. Wings elongate, inner margin nearly as long as costa, outer margin short, 

 convex, little oblique. Hind wings ample, the outer margin convex. White, head 

 thorax and abdominal segments more or less overspread with dark gray ; the collar 

 usually whitish ; legs white. Fore wing white, marked with dark gray along all the 

 margins, at end of cell and over discal nervules, along median vein and in a spot 

 across submedian space, dividing the while ground into four subquadrate patches ; a 

 submarginal light shade ; a faint ocherous spot at base of veins 3-4. This dark 

 marking is variable in extent, and the white marks may be confluent. The patches 

 at end of cell and on submedian space tend to remain darker than the other marks. 

 Hind wing white with a trace only of two dark bands, being a faint discal bar and mark 

 at anal angle. Below white without markings. Expanse 20 mm. 



Female. Fore wings dark slaty gray, uniform, unmarked. Hind wing as in the 

 male, with a little more gray along outer margin and the discal mark obsolete. Ex-
