Fore-wings, mouse-gray, sprinkled with long whitish scales on the outer half of the 

 extreme margin, and all over the apical portion of the wing to the base of the 

 dorsal cilia; abroad whitish-ocherous streak starts from the middle of the base

 fading into the ground-color on the middle of the wing above them ; cilia brown- 

 ish-gray.

 placed by brownish-fuscous or purplish fuscous ; the light scaling on the costa and 

 apical portion of the wing being obsolete, and the hind-wings assume an almost pur- 

 plish tinge.
