SMERINTHUS. 211 



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, un- 

 dulating, 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 ter- 

 minal 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. 



Food-plants. I have secured numbers of the pupa from the mid- 

 dle of October to the beginning of November at the base of 

 willows.

5. S. ophthalmicus Boisduval. Ann. Soc. Ent. t. Ill, 3me ser. xxxii. 



Le S. ophthalmica assez rapproche" de notre ocellata, plus voisin 

 de geminatus de Say, mais 1'oeil n'est pas double et il differe de 

 toutes les especes du meme groupe par sa large bande bruue, 

 anguleuse, qui traverse le milieu des ailes superieures. 



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 conjecture respecting this species, but it will pos- 

 sibly prove to be merely a variety of geminatus.
