*?j IV. ON THE SPECKLED CUTWORM AS A CABBAGE 
WORM. 
(Agrotis c-nigrwm L.) 
Order Lepidoptera. Family Noctuid,e. 
j (Plate X. Fig. 3.) 
times during the last three years, my attention has been 
a large brownish gray caterpillar, marked with oblique 
hes upon the posterior part of the back, found in June 
boring the heads of early cabbage. The character of the 
licted was much more serious than that done by the com- 
bage worm, (Pieris rapes), not only because of the larger 
e caterpillars but especially because of their habit of im¬ 
penetrating the head and mining in all directions, a single 
s destroying the head more completely and in less time 
Id scores of the ordinary cabbage worm. This caterpillar 
s determined as the larva of Agrotis c-nigrum, a common 
10 th, a determination verified later, several times, by breed- 
one of the common cutworms, feeding habitually upon 
l upon a great variety of vegetables, but whose injuries to 
have been hitherto, unnoticed by economic entomologists, 
I am aware, except those done to the young plants by a 
the larvae preceding that which attacks the full-grown cab- 
ir observations on the injury noted have been confined to 
ty of Normal, with the exception of a single report from 
/Boardman, of Stark county, accompanied by specimens 
tworms which he found eating holes in the heads of his 
and causing them to rot. He reported them in July of 
nt year as quite common on his heads of cabbage and on 
bis neighbors. 
DESCRIPTION. 
| lical full-grown larva has the following characters: 
i 2 inches in length by 0.2 inch in width at the widest part 
dy, and is much narrowed anteriorly, the first segment be- 
han half the width of those at the middle of the body, 
y, the diameter hardly lessens, so that the body is obliquely 
behind.
