_Butterfly._--Glossy ochreous, yellow above, with no markings but those which show through from below. On the under side the wings are marked precisely as in the preceding species, except that there are two or three small rays on the secondaries near the base, one on the cell and one on either side of it, of the same tint as the discal transverse band, and in some specimens there is a series of incomplete marginal ocelli on the hind wings. _Early Stages._--Unknown. _Ochracea_ ranges from British Columbia to Arizona, as far east as Kansas. (5) =Coenonympha ampelos=, Edwards, Plate XXV, Fig. 21, ♂, _under side_; Fig. 30, ♂ (The Ringless Ringlet). _Butterfly._--Distinguished from its allies by the total absence of ocelli on both wings, above and below. Otherwise the species is very near _ochracea_. _Early Stages._--These have been described with minute accuracy by Edwards in the "Canadian Entomologist," vol. xix, p. 41. _Ampelos_ occurs from Nevada and Montana westward to Vancouver's Island. (6) =Coenonympha kodiak=, Edwards, Plate XXV, Fig. 22, ♀ (The Alaskan Ringlet). _Butterfly._--Much darker both on the upper and under sides than _C. california_, which in many other respects it resembles. The figure in the plate is that of the type. It is as yet rare in collections. _Early Stages._--Nothing is known of these. It is found in Alaska. (7) =Coenonympha pamphiloides=, Reakirt, Plate XXV, Fig. 27, ♀, _under side_; Fig. 31, ♂ (The Utah Ringlet). _Butterfly._--Rather larger than the other species of the genus found in North America. Easily distinguished by the marginal row of ocelli on the secondaries, which are always present, though often "blind," that is to say, without a distinct dark pupil. The author of the species named it from a supposed likeness to the European _C. pamphilus_. The resemblance is only superficial. _C. pamphilus_ is a much smaller insect and much more plainly marked, judging from the large series of specimens I have received from various European localities. _Pamphilus_ has no eye-spots on the hind wings. They are a conspicuous feature of _pamphiloides_, more so than in any other North American species except _C. haydeni_. _Early Stages._--Unknown. Habitat, Utah and California. (8) =Coenonympha haydeni=, Plate XXV, Fig. 24, ♂, _under side_ (Hayden's Ringlet). _Butterfly._--Dark immaculate mouse-gray on the upper side. On the under side the wings are pale hoary gray, with the hind wings adorned by a marginal series of small ocelli, black, ringed about with yellow and pupiled with pale blue. _Early Stages._--Unknown. Hayden's Ringlet is found in Montana, Idaho, Wyoming, and Colorado. Genus EREBIA, Dalman (The Alpines) "Then we gather, as we travel, Bits of moss and dirty gravel, And we chip off little specimens of stone; And we carry home as prizes Funny bugs of handy sizes, Just to give the day a scientific tone."
