THE CANADIAN ENTOMOLOGIST. 39 



toward an understanding of the iiiis-Henrici difficulty, I spoke of this 

 specimen as " an undoubted ^ iriis''^ The reasons for my error at that 

 time are, I think, obvious. 



The Henrici of Grote and Robinson is figured, as stated, in the 

 Butterflies of New Hampshire (fig., p. 45, under surface of 9?) and also 

 in Holland's Butterfly Book (plate XXX, fig. 21, upper surface of 2). 



IVrighfs niisidentification. — If one may judge from the rather 

 poorly-marked specimen figured by Wright as Mossi, the species 

 represented \s polios? At any rate, it is ?iot the Mossi of Hy. Edwards. 

 The type Mossi is now in the Museum of Natural History in New York 

 City, and the species for which it stands has never been figured hitherto. 

 In the original description^ drawn from that type Edwards says of the 

 under side of the secondaries : " The marginal spots are large, distinct^ 

 bright chest njit-hroivn, six in number, each surmounted by a small black 

 lunule." And concerning the mesial line (secondaries beneath) it is 

 '• narrow, whitish, with a very large and sharp angle at the median nerved 

 Also concerning the white line crossing the primaries beneath : "From the 

 costa entirely across the wing is a sinuous white band bent outwardly at 

 the middle, and edged above by a deep chestnut-brown shade." The 

 wings above are described as ''''entirely bright chestnut-broivn, a little 

 clouded, with dusky at the apices and on the extreme margins." It is 

 further stated that the fringes are "wholly white," but this is not strictly 

 the case even in the type. 



How far these characters may be regarded as of specific importance 

 remains to be determined, but Wright's illustration is a long way from 

 corresponding in essentials with tlie type or fitting the description. 



Edwards described Mossi as a variety of irus, adding that ''it is quite 

 l)0ssible that it is a distinct species ; the uniform deep brown base of 

 secojidaries giving it a most peculiar appearance." \Vrightsays in the text 

 accompanying his figure : " The essential peculiarity of Mossi is the 

 bleached, washed-out appearance of the under side of hind wings, ' giving 

 it a most peculiar appearance,' as the description truly says." (My 

 italicization throughout.) As a matter of fact, a fresh specimen of Mossi 

 is as boldly and cleanly marked as any species oi Incisalia yet named. I 

 am of the opinion that the species figured by Wright is polios.
