second brood appeared July 29. Our miscellaneous collections of 
fche imago made by sugaring and from the electric light (where, 
however, the species rarely appears) bear out the above division 
into two broods, a lapse occurring from June 13 to August 4, 
after which the moth was taken occasionally to September 2. ±he 
tall brood of this cutworm does little, if any, injury, and the 
spring brood may ordinarily be expected to cease its' mischief by 
about the first of May. 
Among the food plants of the spotted cutworm, we have noticed 
Lobelia and Helianthus; and a single specimen was seen m spring 
to eat the eggs of grasshoppers. 
The Chocolate-striped Cutworm. 
(Afjrotis bicarneci, Guen.) 
(Plate III., fig. 3.) 
This species seems not usually destructive in Illinois, but is 
here mentioned because of the general similarity of its peiiod of 
development and feeding habits to those of the moie injuiious 
species. 
DESCRIPTION OF LARVA. 
This is a distinctly striped cutworm, of rather light color, 
especially distinguished by the strongly marked dark stigmata! 
stripe, the greater distinctness of the lines behind, and the round 
black spots or dots surrounding the piliferous tubercles upon the 
posterior segments. These are commonly, but not invariably, mucn 
more distinct here than in front. A dusky brown dorsal band, 
uniform, or with wavy margins, divided by a light median line 
(which is sometimes obsolete before the middle) occupies the 
area between the two inner rows of piliferous spots. The dark 
stigmatal stripe varies from medium brown to dark chocolate oi 
nearly black. It ends on the 11th segment, and on the thorax 
usually becomes confused with the ground color. 
The stigmata are commonly white, rimmed *with black. Sides 
above the stigmatal band dusky flesh-color or cream-color, much 
specked with black, and divided by a cream-colored subdoisal 
line bordered with black or brown, the upper border darker and 
broader on the 9th, 10th, and 11th segments. The inner row of 
piliferous spots usually much the most conspicuous, often forming two 
quite evident rows of small circular blotches extending the whole 
! length. 
The substigmatal area with a rather distinct cream-colored oi 
flesh-colored band above; below greenish mottled with whitish and 
brownish. Venter between the prolegs commonly plain, and, like 
the latter, whitish or pinkish. The remainder of under surface 
like the lower part of substigmatal area. Jointed legs commonly 
pale brown.
