Agrotis nigricans (Linn.), var. maiji. The larva of this moth is described 
by Fitch (9th Rep. Ins. New York, pp. 237-250), under the name of the 
Corn Cut-worm, from its cutting off young' Indian corn and other plants near 
the ground. The habits of the larva are described in great detail, and the 
imago is figured, pi. 4. figs. 2 & 3. The chief enemy of this species is Calo- 
so7na colidum.
