light ochreous brown, darker above on first three segments; legs 

 white, tarsi handed with dark brown. 



Fore wing dark grayish brown; under a lens this dark color is 

 very mottled, as the bases of the scales are lighter, ochreous or whit- 

 ish, than the tips. On and below the fold is a whitish streak, defined 

 by an oblique dark streak on inner third and the dark brown of inner 

 line at outer third. There is a distinct white spot on outer third of 

 costa. between the inner and subterminal lines. The inner line is 

 dark brown from outer third of costa, with two long and sharp out- 

 ward angulations at upper and lower thirds; from the latter it sends 

 a long line, dilated at end, to middle of dorsum; it is edged inwardly 

 with white. The brown subterminal line from outer fifth is straight 

 and almost runs into incision; below this it is not distinctly denned, 

 but indicated by brown scales on the veins, giving a wavy appear- 

 ance, to tornus. The space between these lines is more white than 

 elsewhere on the wing, but is dusted with brown, in some specimens 

 heavily. The subterminal line is edged with white on upper third, 

 beyond which is a broad olivaceous brown line, then a fine white line, 

 followed by a darker brown triangular apical spot. Below incision, 

 on termen, is an oblong white spot. Terminal line, before cilia, very 

 narrow, brown. Cilia above incision white, divided by a blackish 

 line near base and blackish outwardly; below incision grayish white. 



Hind wing cinereous gray, cilia white, with a faintly darker line 

 close to base; underside paler. Underside fore w T ing light gray, with 

 white costal marks faintly repeated.

This species is unlike any of our M esolia-J " 'ri '< > n a pteryx group in the 

 decided grayer hue of the fore wings; all the other species have a 

 superficially ochreous or ochreous-brown tinge, and it can be easily 

 separated by this character; the average size is also smaller.
