Genus CEneis 



Butterfly.— This species has thin wings, and is much darker 

 in color than any of the species which have thus far been men- 

 tioned. It is restricted in its habitat to the summit of Mount 

 Washington, in New Hampshire, and only reappears on the high 

 mountains of Colorado and in Labrador. Its life-history has 

 been very carefully worked out. It is to be hoped that entomol- 

 ogists and tourists resorting to Mount Washington will not suf- 

 fer it to disappear by reason of too wholesale a capture of the 

 specimens, which hover about the barren rocks on which the 

 race has existed since the great continental ice-sheet melted away 

 and vanished from the face of New England. Expanse, 1.75 

 inch. 



Early Stages. — The curious reader is again referred for a 

 knowledge of these to the pages of Scudder and Edwards. 

 They are similar to those of other species, and the generic de- 

 scription which has been given must suffice for all in this work. 



(10) CEneis brucei, Edwards, Plate XXVII, Fig. 7, $ (Bruce's 

 Arctic). 



Butterfly.— Though somewhat closely related to the last spe- 

 cies, Bruce's Arctic may at once be distinguished from it by the 

 broad dark band on the under side of the secondaries and the 

 great translucency of the wings, which permits a label to be 

 read through them. It is found in Colorado and in British Co- 

 lumbia at an elevation of from twelve to thirteen thousand feet 

 above sea-level. Expanse, 1.7s inch. 



Early Stages. — All we know of these is contained in the 

 pages of Edwards' great work. 



(11) CEneis taygete, Hiibner, Plate XXVII, Fig. 6, $ (The 

 Labrador Arctic). 



Butterfly.— Much like CE. brucei, but the wings are not so 

 translucent as in that species, and the broad mesial band on the 

 under side of the hind wings is differently shaped, being more 

 strongly directed outward just below the costa. The figure in 

 the plate is from a specimen taken at Nain, in Labrador. Ex- 

 panse, 1.75 inch. 



Early Stages. — Unknown. 



There are eight or nine other species of CEneis in our fauna, 

 but they are all arctic, and most of them very rare. Those we 

 have described and figured will give a good idea of the genus.
