﻿184 CLEMENS' SYNOPSIS OF 



basal half of medio-posterior interspace filled by a dark brown or a ferruginous brown patch, joined by a 

 line of the same hue crossing the disc from the costa and obliquely by another from the upper third of 

 inner margin, shaded posteriorly with brownish, through the centre of which passes the sub-median nervule ; 

 discal spot pale, margined with brown ; a brownish band, margined before with darker brown, crosses the 

 base of the nervules, and is followed by two or three more or less distinct rosy gray and brownish, undu- 

 lating, subterminal lines ; a deep brown, semi-oval patch at the tip edged with whitish, and a ferruginous 

 brown spot above inner angle, usually with two smaller spots above it ; the middle of terminal space dark 

 brown. Posterior wings rosy, along exterior and terminal border yellowish gray ; ocellus black, emitting 

 a short, broad line to inner angle, and with two or three blue pupils.

88. S. ophthalmicus Boisduval, Ann. Soc. Ent. t. III. 3me Ser. xxxii. 



Le S. oplitlialmica assez rapproche de notre Ocellata, plus voisin de Gemina de Say, mais l'oeil n'est 

 pas double et il diffe.re de toutes les especes du meme groupe par sa large bande brune, anguleuse, qui 

 traverse le milieu des ailes superieures. 



S. ophthalmicus is nearly related to the European ocellatus, and more intimately 

 to geminatus of Say, but the pupil is not double, and it differs from all the species of 

 the same group by having a large, angular, brown band traversing the middle of the 

 superior wings. 



This description of M. Boisduval is almost too indefinite to authorize even a con- 

 jecture respecting this species, but it will possibly prove to be merely a variety of 

 geminatus.
