Early Stages.—These have been described and beautifully figured by Edwards in the third volume of his great work, to which the reader may refer. The caterpillar is green, cylindrical, tapering before and behind, marked with longitudinal pale-yellow lines. The chrysalis is green or black, striped with narrow white lines. The egg is somewhat firkin-shaped, flat at the top and base, vertically ribbed, and honey-yellow. The larva feeds on grasses.
Charon is found in the Northwest, ranging from British Columbia as far as New Mexico.
(7) Satyrus œtus, Boisduval, Plate XXVI, Fig. 7, ♂; Fig. 8, ♂, under side (Boisduval's Satyr).
Butterfly.—Larger than charon, paler on the upper side, especially in the female sex, in which the outer third of the primaries is reddish-fawn. On the under side the secondaries of the male are without ocelli, or at most faint traces of ocelli appear. In the female the ocelli near the anal angle of the secondaries are usually well developed. Expanse, 1.60-2.00 inches.
Early Stages.—These await description.
The species is found in northern California.
(8) Satyrus sthenele, Boisduval, Plate XXVI, Fig. 20, ♂, under side (The Least Wood-nymph).
Butterfly.—Quite small, superficially resembling charon. The female is paler and the ocelli are larger and more distinct than in charon. The distinguishing mark of this species is the irregular, dark, twice-strangulated band of the secondaries, bordered on both sides externally by whitish shades. This is shown in our figure. Expanse, 1.40-1.50 inch.
Early Stages.—Unknown.
The species is Californian.
