margined, forming a small blackish spot on costa ; terminal space grey, 

 veins suffused with black ; subterminal line cloudy, whitish, somewhat

 lines. Hindwings 1\, very pale whitish-grey, lunule, postmedian line, and 

 hindmargin hardly darker ; cilia whitish, with two grey lines. 



Of somewhat doubtful affinity ; recognizable by the rather broad distinct 

 lines, dark suffusion towards costa, and clear white lower half of reniform.
