Expanse of wings from 1.15 to 1.25 inches. 



Upper surface blackish brown, sprinkled with pale 

 bluish scales. A band, somewhat lighter than the basal 

 part of the wing, crosses the fore wings so as to bring 

 the end of the cell in its middle. This band is heavily 

 overlaid with bluish scales, especially on the costal half. 

 Preceding this is a band of darker brown, subquadrate, 

 contiguous spots, with a slight sprinkling of bluish 

 scales. Beyond the band which crosses the end of the 

 cell is another band of ovate spots, the bases rounded, 

 the costal half with the spots narrower and more pointed, 

 the anterior four or five with whitish, imperfectly-defined 

 spots in their centres, and the rest overlaid with bluish 

 scales. Between this band and the outer margin is a 

 row of obscure brown spots without the pale scales. The 

 hind wings have two irregular rows of dull ochraceous 

 spots along the outer margin. 



Under side paler than the upper side, the hind wings 

 with the two rows of spots repeated. The fore wings 

 have two rows of spots parallel with the outer margin, 

 both elongate, the outer on the edge and extending into 

 the fringe. Inside these, and corresponding with the 

 second band of the upper side, is a row of white spots, 

 the first six small, the seventh and eighth larger and 

 quadrate, the ninth and tenth obscure.
