beyond the middle by two angulated, dull ochre-yellow 

 lines, overlaid more or less with dark brown. The first or 

 median line crosses the end of the cell, where it is angu- 

 lated. The second or subterminal, crosses the wing about 

 half way between this last and the end. Terminal line dark 

 brown, and a dark brownish cloud extends obliquely in from 

 the apex to the subterminal line, but does not reach the 

 costa. A narrow, ochre-yellow line, somewhat curved, ex- 

 tends from the middle of the base of the wing to the sub- 

 terminal line near the anal angle, and a similar line, though 

 less plainly marked, runs parallel between this line and the 

 hind margin. Terminal space more or less gray. The outer 

 margin regularly excavated below the apex. Fringes pale 

 metallic lead color. Hind wings pale fuscous, with lighter 

 fringes.

The following descriptions of the larva and pupa are com- 

 piled from those published by Prof. S. A. Forbes in the 

 "Fourteenth Report of Noxious and Beneficial Insects of 

 Illinois," pp. 14, 15, 1895: 



Larva. Head dark chocolate brown, slightly and irregu- 

 larly rugose, with long yellowish hairs ; upon the front a 

 white S-shaped mark ; cervical shield yellowish, with a 

 white median line ; anterior edge whitish, and an oval black 

 spot on the sides. Below the lateral edges of the cervical 

 shield are two hairy tubercles ; second and third segments of 

 thorax each with two rows of hairy tubercles, the anterior 

 of four, the posterior of two large quadrate spaces, some- 

 times united in the middle. From the fourth to the tenth 

 segment the hairy tubercles above the spiracles are in two 

 transverse rows of four each, those of the anterior row being 

 quadrate with rounded angles, and as large as the interspaces ; 

 those of the posterior row transversely elongated, about twice 

 as long as wide. Lateral tubercle of anterior row immedi- 

 ately above the spiracle emarginate at its posterior inferior 

 angle, on all the segments from the sixth to the ninth ; on 

 these segments a smaller tubercle behind and beneath the 

 spiracle, and two others between the spiracle and the pro- 

 leg; a narrow arcuate tubercle, with long hairs outside, in
