FAMILY BRUSH-FOOTED BUTTERFLIES. 107 



scarcely spinous tubercle. Body naked, minutely papillate, yel- 

 low-green on the bf.ck, blue-green on the sides, with faint paler 

 stripes connecting the base of the head tubercles and of the 

 deeply forked caudal spines. Length IJ inches. 



Chrysalis. — Yellow-green or blue-green, finely specked 

 throughout with pale yellow, with a cream-yellow line along the 

 dorsal crest, which extends the length of the body. Length more 

 than f inch. 



The eggs, which are subglobular, with about eighteen 

 slight vertical ribs and pale green, are laid on the under 

 side of the leaf of the food-plant, either singly or in small 

 clusters of a dozen or less, and hatch in three or four days. 

 The caterpillars feed upon Celtis, hackberry, and, lining 

 the U23per surface of a leaf so as to cause the sides to curl 

 slightly upward, are partially concealed from view. The 

 chrysalis hangs from seven to ten days. The butterfly is a 

 southern species and extends nearly but not quite so far 

 north as C. clyton. It appears to be double-brooded, but 

 some of the caterpillars of the first as well as of the second 

 brood hibernate when half grown and, in the opinion of 

 Edwards, some butterflies also hibernate. The first brood 

 of butterflies of the season appears in June, the second in 

 August ; the butterfly life is long, so that some are flying 

 most of the season, Avhile the caterpillars (except those 

 that hibernate) often feed so rapidly that all the earlier 

 stages are passed within a month.
