(1) Cœnonympha ochracea Edwards, [Plate LXV], Fig. 1, ♂ (The Ochre Ringlet).
Glossy ochreous yellow above, without dark markings except as those of lower side faintly show through. On under side the fore wing has an eye-spot near apex, and the hind wing has a submarginal row of incomplete eye-spots, which in some specimens is wanting. Ground-color of under side of fore wings as above; of hind wings gray, interrupted about middle by a lighter band, and lighter rays about the cell near base. Expanse 1.25-1.50 inch. Ranges from British Columbia to Arizona eastward to Kansas and Nebraska.
(2) Cœnonympha inornata Edwards, [Plate LXV], Fig. 2, ♂ (The Plain Ringlet).
Reddish ochraceous on upper side with outer margin of fore wings and hind wings laved with darker. On the under side there is an ocellus near the apex of fore wing and on the hind wing, which is dark gray, a yellow curved mark beyond the cell and a couple of pale yellow spots near the anal angle.

Genus EREBIA Dalman
(The Alpines).
PL. LXVI
Rather small butterflies, dark in color, with eye-spots on the wings, most numerous on the under side. Veins of fore wing thickened at base; lower radial in some cases projected inwardly into the cell at point of origin. Outer margin of both wings evenly rounded. Egg subconical, ribbed, the ribs often intersecting each other. Larva with globular head, body tapering backward, last segment bifurcate. Chrysalis convex dorsally and ventrally, humped on thorax, produced at head, light brown or ashen gray.
The genus is arctic and confined to the far north, or to the summits of high mountains, which have an arctic climate. There are many species in the northern hemisphere, of which we select two for representation.
