whitish stripe above the middle of the wing and below two 

 fuscous longitudinal lines on the upper part; this whitish 

 stripe extends from the base nearly to the subterminal line, 

 where it ends acutely in a dark line reaching to the end of 

 the wing. Bordering the acute end of the stripe, above and 

 below, are two small, white, wedge-shaped spots, pointing 

 inwardly. A diamond-shaped, silvery- white spot in the 

 apex of the wing, with a dark streak and lighter patch above 

 it, Median line dark brown, arising from the middle of the 

 costa and sending a very acute angle outward, which en- 

 closes the end of the white stripe and gives off two outward 

 and one inward acute angles below the stripe, and ends near 

 the middle of the hind margin. Subterminal line, bordered 

 on each side with white in the first part of its course, arises 

 from the outer fourth of the costa and runs obliquely out 

 beyond the end of the stripe, where it forms a right angle 

 and extends to the hind margin within the anal angle, giv- 

 ing off a tooth inwardly in the middle of its course.

when it tapers off acutely on the outer fourth ; a brown 

 apical patch on the costa, with a white one below it. Sub- 

 terminal line forming a right angle at its costal third. Ter- 

 minal space, below the apical spots, dark; two or three 

 short white parallel lines run from the tip of the white 

 stripe to the subterminal line. Fringes much paler. Hind 

 wings dark, argillaceous above and beneath. Differs from 

 all other species in its peculiar dark hue, especially on the 

 hind wings.
