Genus CEneis 
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, fiat 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.

Butterfly. —Larger than charon , paler on the upper side, 
especially in the female sex, in which the outer third of the pri¬ 
maries is reddish-fawn. On the under side the secondaries of 
the male are without ocelli, or at most faint traces of ocelli ap¬ 
pear. In the female the ocelli near the anal angle of the secon¬ 
daries are usually well developed. Expanse, 1.60-2.00 inches. 
Early Stages.— These await description. 
The species is found in northern California.

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.
