oats, barley and strawberry. In mixed fields of timothy and 

 clover, it is recorded that the former was destroyed while the 

 clover remained nninjured. Beans, lettuce and cabbage are 

 sometimes attacked. Unlike the more common cutworms, 

 this species rarely comes to the surface, but works in a burrow, 

 feeding on the roots and stems below ground. There is a case 

 on record in Ohio of peach seedlings being destroyed in this way. 

 Hibernation takes place as partly grown larvae. Some of 

 them become mature in early May but the greater number 



during June and July. The 

 full-grown caterpillar is 1^ 

 inches in length, dirty white 

 with a greenish tinge and 

 has a translucent glassy 

 appearance; the head is 

 reddish brown. Pupation 

 takes place in earthen cells. 

 If inches in length by f 

 inch in width. These cells 

 are formed a few inches 

 below the surface of the 

 ground. The pupa' is nearly an inch in length and of a 

 reddish brown color. 



The moth has an expanse of 1| to If inches. The front 

 wings are pale ashy gray to dark brownish gray, mottled with 

 darker brown. The subterminal transverse line is wdiitish and 

 usually distinct. On the inner margin of this line is a row of 

 five or six wedge-shaped black spots. The hind wings are 

 brownish, darker on the outer third (Fig. 168). There is ap- 

 parently but a single brood annually, the eggs being laid in the 

 latter part of the season, the greater number after August first.
