wings have a transverse yellow band beyond the cell, 

 sometimes a little ochraceous, and often more or less 

 encroached upon by the brown ground. On this 

 area are two ocelli, round, black, or variable size, 

 and with or without a central point, which is white 

 with blue scales. Behind the cell is a blackish indis- 

 tinct sexual dash in the males. The hind wings have 

 a small ocellus in a yellow ring near the anal angle 

 (often wanting). 



Underside yellow-brown; the band enlarged and 

 of a paler color; the ocelli repeated, enlarged; the 

 marginal lines distinct; the brown area covered with 

 abbreviated darker streaks, which over the base and 

 disks form somewhat concentric broken rings, limited 

 without by a common dark stripe. On the fore wings 



it is irregularly sinuous from margin to margin, throwing out a rounded 

 prominence against the cell, followed by a rounded sinus on the median 

 interspace. Across the middle of the cell, and below it, a dark stripe; 

 the extra discal area less streaked. The ocelli vary from none to six, 

 the full number being most often present, disposed in two groups of 

 three, the middle one of each group the largest; all black, rounded, in 

 narrow yellow rings, and with white dots in the center edged by blue, 

 scales. 



Female This differs from the male in the band being generally

broader, clearer, and well defined on both edges, the ocelli well developed, 

 with occasionally additional black points on the hind wings corresponding 

 to the ocelli on the under side. A larger percentage than of the males 

 have no ocelli on the under side of the hind wings. 



The above description applies to typical form alope. Variety
