Genus Chlorippe 



manner of flight it closely resembles the species of the genus 

 BasilarcUa. 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 CHL-ORIPPE, 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. 



FIG. no.-Neu- E S- The e gg s > which are deposited in clus- 

 ration of the genus ters, are nearly globular, the summit broad and 

 Cbionppe, $. 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 Satyr/nee. 



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
