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, 6 (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, 1.75 inch. 
Early Stages.—AM we know of these is contained in the 
pages of Edwards’ great work. 
(11) CEneis taygete, Hubner, Plate XXVII, Fig. 6, 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 theyare all arctic, and most of them very rare. Those we 
have described and figured will give a good idea of the genus.
