108 THE COMMONER BUTTERFLIES. 



tinct, more distinctly ringed with yellow, those of the hind wings 

 with satellites ; two distant nearly straight brown lines cross 

 the middle of the wings. Expanse If inches. 



Caterpillar. — Head dirty white, heavily mottled with brown, 

 densely papillate, the summits angulate, almost tuberculate. 

 Body naked, but covered with dense pile arising from papillae in 

 transverse series, pale brown with a greenish tinge, with a dark 

 dorsal stripe and obscure brown longitudinal markings ; a dis- 

 tinctly constricted neck and short caudal fork. Length fully f 

 inch. 



Chrysalis. — Pallid brown, heavily flecked with griseous, the 

 abdomen with a pair of distinct, distant, longitudinal ridges. 

 Length less than ^ inch. 



The subgiobular, reticulated, very ])'d\Q green eggs are 

 laid singly on blades of grass, living or dead, and hatch in 

 about thirteen days. The caterpillars feed upon grasses 

 and usually only by night, concealing themselves by day 

 among the roots or on dry sticks on the ground; they are 

 exceedingly sluggish in movement and are lethargic and 

 long-lived, hibernating when more than half grown but 

 not mature. The chrysalis hangs for sixteen days. The 

 butterfly is a southern species, but extends far northward 

 into nearly all the settled parts of Canada exce2:)t Mani- 

 toba, and it has not been reported from Minnesota, though 

 it probably occurs there. It haunts groves and open spots 

 and roads in the forest, is single-brooded, and flies from 

 the last week in May through July, with accessions to the 

 l)rood certainly through June. 



AiK)tlier species of Cissia, C. sosylnus, a southern form, occurs as 

 ftir north as West Virginia.
