Genus Ccenonympha 



same tint as the dlscal transverse band, and in some specimens 

 there is a series of incomplete marginal ocelli on the hind wings. 



Early Stages. Unknown. 



Ocbracea ranges from British Columbia to Arizona, as far 

 east as Kansas. 



(5) Ccenonympha ampelos, Edwards, Plate XXV, Fig. 21, 

 $ , under side; Fig. }o, 6 (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 accu- 

 racy by Edwards in the " Canadian Entomologist," vol. xix, p. 41. 



Ampelos occurs from Nevada and Montana westward to 

 Vancouver's Island. 



(6) Ccenonympha 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) Ccenonympha 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. Pampbilus has 

 no eye-spots on the hind wings. They are a conspicuous fea- 

 ture of pamphiloides, more so than in any other North American 

 species except C. baydeni. 



Early Stages. Unknown. 



Habitat, Utah and California. 



(8) Ccenonympha haydeni, Plate XXV, Fig. 24, $ , under 

 side (Hayden's Ringlet). 



Butterfly. Dark immaculate mouse-gray on the upper side.
