Genus Chlorippe 
manner of flight it closely resembles the species of the genus 
Basilarc-hia. Expanse, 2.50-3.00 inches. 
Early Stages .—So far as is known to the writer, these have 
not been described, except partially by Henry Edwards in the 
“ Proceedings of the California Academy of Sciences,” vol. v, 
p, 171. The caterpillar feeds upon oaks. 
The insect is found in California, Nevada, Arizona, and 
Mexico. 
Genus CHLORIPPE, Boisduval 
(The Hackberry Butterflies) 
Butterfly .—Small butterflies, generally some shade of fulvous, 
marked with eye-like spots on the posterior margin of the 
secondaries, and occasionally upon the outer margin of the 
primaries, the fore wings as well as the hind 
wings being in addition more or less strongly 
spotted and banded with black. The eyes are 
naked; the antennae are straight, provided with a 
stout, oval club; the palpi are porrect, the second 
joint heavily clothed with hairs, the third joint 
short, likewise covered with scales. The costal 
vein of the fore wing is stout. The first subcostal 
vein alone arises before the end of the cell. The 
cell is open in both wings. 
Egg .—The eggs, which are deposited in clus¬ 
ters, are nearly globular, the summit broad and 
convex. The egg is ornamented by from eighteen 
to twenty rather broad vertical ribs, having no great elevation, 
between which are numerous faint and delicate cross-lines. 
Caterpillar .—The head is subquadrate, with the summit 
crowned by a pair of diverging stout coronal spines which have 
upon them a number of radiating spinules. Back of the head, on 
the sides, is a frill of curved spines. The body is cylindrical, 
thickest at the middle, tapering forward and backward from this 
point. The anal prolegs are widely divergent and elongated, as 
in many genera of the Satyrince. 
Chrysalis .— The chrysalis is compressed laterally and keeled 
on the dorsal side, concave on the ventral side, the head dis¬ 
tinctly bifid. The cremaster is very remarkable, presenting the
