[a]Fig. 117.]—Neuration of the genus Cœnonympha.
Chrysalis.—Ventrally straight, dorsally convex, strongly produced in a rounded, somewhat keeled eminence over the thorax; pointed at the end. Generally green or light drab in color, with dark markings on the sides of the wing-cases.
This genus is distributed throughout the temperate regions both of the Old and the New World, and includes in our fauna a number of forms, the most of which are peculiar to the Pacific coast.
(1) Cœnonympha california, Doubleday and Hewitson, Plate XXV, Fig. 14, ♁; form galactinus, Boisduval, Plate XXV, Fig. 9, ♂; form eryngii, Henry Edwards, Plate XXV, Fig. 10, ♂ (The California Ringlet).
Butterfly.—This little species is to be distinguished from its near allies by its white color. The form galactinus is the winter form; the form california the summer form. The former is characterized by the darker color of the hind wings on the under side and the more prominent development of the marginal ocelli. The form eryngii is simply a yellower form, with less dark shading on the under side.
Early Stages.—These have been most carefully and beautifully worked out by Edwards, and the reader, for a full knowledge of them, may consult the splendid plate in "The Butterflies of North America," vol. iii.
The species ranges from Vancouver's Island southward on the Pacific coast and eastward into Nevada.
(2) Cœnonympha elko, Edwards, Plate XXV, Fig. 25, ♁, under side; Fig. 26, ♂ (The Elko Ringlet).
Butterfly.—Yellow on both sides of the wings, the lower side paler than the upper, and the basal area lightly clouded with fuscous.
