the dorsal rows of spines, and another just outside the 

 first laterals. The spines from six rows are long, fleshy, 

 black, each beset with short black hairs. Head black. 



After the second rnoult the larva is mottled and striped 

 with light and dark cinereous, the spines longer, each (lull 

 yellow at base. 



After the third moult the dark portions become black, 

 and the light a dirty white, and the dorsum has a white 

 stripe with a central black line ; at the juncture of several 

 segments a transverse white stripe, on which are short 

 black lines. Each segment is crossed longitudinally by 

 black stripes, interrupted by the spines, with a wedge- 

 shaped mark between the spines. Head light brown. 



The color after the fourth moult is buff, with th,e mark- 

 ings much as before. The larva moults five times before 

 reaching maturity, when it is 1.75 inches long, velvety 

 black, banded and striped with ochrey yellow changing 

 to dull orange or red, and furnished with six rows of 

 tapering, fleshy spines, each of which has several small 

 black bristles. Two of the rows along the back are 

 silvery white, with black tips, those at the end of the 

 rows somewhat smaller. The spines of the rows along 

 the sides are smaller, and yellowish or orange at the base. 

 The head is reddish above and black beneath. 



The chrysalis, to which the larva changes in some shel- 

 tered place, is 1.1 inches long, and shaped as in allied 

 species. The color is brown and yellow over the ab- 

 domen, the mesonotum pinkish brown, the wing-cases 

 brown, pink-tinted, with dark brown and black patches 

 over the body. 



This species, like others of the genus, feeds on violets 

 in the larval state. In the North it is single-brooded,
