Among the North American species known to me in nature, there is 

 not one identical with, or even similar to any European ; and the opinions 

 of prominent Transatlantic colleagues, as to whether identical species 

 occur in the two countries (Sec/, ccntanrcce excepted, which is common to 

 the Arctic regions of both continents) are very far divergent. Edwards 

 on the authority of Boisduval cites in his Catalogue, Sy/vanns and Tages, 

 and besides, also, comma as American ; while he places Pamph. Juba, 

 Manitoba, Colorado, Nevada and sylvanoides* (which are regarded as good 

 species by Scudder) as varieties of comma. I refrain from expressing any 

 opinion in this question of species, not knowing any of the forms. As to 

 Sylvanus and Tages, 1 would prefer to drop them from the list until their 

 right to be classed among the indigines of America shall have been based 

 upon more reliable authority than that of Boisduval. If we may trust 

 Lederer's statements, Boisduval's Californian Tages var. Cervantes, would 

 appear to be not only a distinct species, but also of a different genus from 

 Tages; for it is said to deviate " not only in coloring, design and in its 

 diaphanous, glassy spots, but also in the cut of the wings and in the pos- 

 terior legs of the male, which have only apical spurs and a long hair- 

 pencil" (Wiener Entom. Monatschr., 1857, p. 78). Thus there would 

 remain no resemblance whatever to Tages, and the carelessness shown in 

 declaring identical two such radically distinct forms, would hardly be 

 expected even from Boisduval, although he is so little scrupulous in such 

 matters. Possibly Lederer's statements may have resulted from a con- 

 fusion of species. 



* In the Memoirs of the Boston Sot. N. //., Vol. II, 1'. Ill, No. IV, these 

 species, and also comma, are minutely described and well figured, and the anal appen- 

 dages (which Mr. Scudder estimates as of special value) are explained. He "also 

 represents, in the same paper, the times of appearance of the species as different.
