 of raised scales, and another on the inner margin joining the 

 band behind. Exterior to the band the wing is touched with 

 ochreous, containing in the middle a short dark-fuscous

 third of the fold, and a larger patch of the same hue on the 

 inner margin at the end of and above the fold. Between the 

 tufts is an oblique dark-brownish costal streak, nearly joined 

 at an angle by another of the same hue in the middle of the 

 wing and exterior to the first tuft ; the fold is tinted with
