 middle, proceeding from the apex to the middle of the interior margin, 

 ferruginous, edged with pale yellow exteriorly ; two very fine dark lines 

 between the subterminal line and the exterior margin, proceeding from 

 the apex almost to the inner angle where they lose themselves in a 

 darker shade composed of ferruginous atoms, the outer one better de- 

 fined than the other, slightly curved for half its length and then very 

 wavy; teeth on the inner margin orange ferruginous, the interior one 

 more than double the size of the exterior. Posterior wings dull gray-
