AMERICAN LEPIDOPTERA. 375 



brown, with the markings as in male but indistinct and often obsolete; 

 silver mark more open and more slight. 



ILih. — Rocky Mountains. Colorado. From several males and females 

 in collection of Mr. Reakirt. 



This species resembles C-aJbnm in color and markings of upper sur- 

 face, being more spotted, noticeably so, on secondaries, and of a much 

 paler color, than Comma^ while it more resembles this last in markings 

 of under side. C-albnm is however a Protean species, sometimes even 

 in all respects coming very near Faunus. But in a series of specimens, 

 in my possession, part of which were sent me by Mr. II. W. Bates as 

 exhibiting variations, most differ decidedly from any American form 

 known to me. Our several species of Grapta, though closely allied to 

 each other, keep up their distinctive characters. The series including 

 C-alhnm would run thus: luterroijationis^ Umhrosa (Lintner), Comma, 

 Satijrus, C-album, Faiunis, and with an interval, that is, in another 

 group, Oreas, P/ogiic, Gracilis. I have never seen reason to believe 

 C-albmn to be an American species. Authors have applied that 

 name to Comma and to Faunus. As to the Californian species ( Oreas) 

 above described, if the larva did not appear to be dissimilar, I do not 

 think such a form could be included among the aberrations of even 

 so variable a species as C-alhum. 



C^NONYMPHA KODIAK, n. Sp. 



Male. Expands 1.5 inch. Upper side light brown with a grey 

 shade, the whole surface having a silky gloss and appearing either 

 brown or grey according to the point of view; a common whitish bar, 

 caused by the transparency of the wings. 



Beneath, from base to beyond middle of wings brown with grey 

 scales on primaries and blue-grey on secondaries; this space edged by 

 a common band of pure white; thence to margin pale brown with a 

 whitish or bluish grey tint as viewed. 



Body above brown; beneath, thorax covered with blue-grey hairs; 

 palpi blue grey; antenna) annulated brown and white.

OiENONYMPHA BrENDA, n. sp. 



Male. P^xpands 1.4 inch. Upper side light buff, immaculate. 

 Under side a shade more yellow; primaries have a faint, transverse, 

 reddish line beyond the cell, commencing at sub-costal, thence straight 

 to upper median, after which it is tortuous and disappears near lower 

 median. Secondaries have a similar line angular to end of cell thence 

 tortuous to abdominal margin ; primaries have a large sub-apical round
