240 THE BUTTERFLIES OF THE 



The mature larva is 1 inch long, flat at base, the 

 dorsum rounded, the last joint forked. Color of dorsum 

 yellow-brown, the sides darker; a dorsal brown band, 

 and on each side of this, from joint 4 to joint 11, is a 

 series of dark brown patches. The subdorsal area is sep- 

 arated from the dorsal by two wavy parallel lines, the 

 upper dark, the lower yellowish, and on the side of 

 each joint from 5 to 11 there is an oblique dark stripe. 

 Basal ridge yellowish, the tails tipped with red. Head 

 yellow-brown, with a small conical process on each ver- 

 tex. The whole surface of the body is covered with 

 sharp tubercles of irregular size, each emitting a short 

 brown hair. 



The chrysalis is .5 of an inch long, shaped as Sosybius ; 

 cylindrical ; the abdomen stout, and larger than the an- 

 terior portion. Color pale yellow-brown, the wing-cases 

 and anterior parts streaked with fine, abbreviated brown 

 lines ; brown spots on the wing-cases, the abdomen with 

 two brown stripes and two rows of brown dots. The 

 butterfly emerges in eleven days. 



There are probably two broods in a season, the last 

 brood of larvae passing the winter in a torpid state. 

 They feed upon grass, the eggs being deposited singly 

 upon the blades. They are very sluggish at all times, 

 and frequently pass days without eating.
