plants in rye fields, (doubtless engaged in laying their eggs), 
Iso at the bases of the stalks of sprouting corn. On the 19th, 
nville, they were likewise seen at the bases of stalks of wheat, 
/ere taken by sweeping the meadows. In the former situation 
-were several times observed in coitu. On the 22d, considerable 
ers, all adult, were obtained from rye. No young could be 
ed, although the adults were frequently paired. The latter 
also occasionally numerous in corn fields. On the 24th, they 
taken frequently by sweeping oats, and likewise found coupled 
the roots of corn. On the 5th July, the young were noted 
mtly at bases of stalks of rye in fields at Normal, and on the 
were seen occasionally on corn beneath the sheaths. August 
11 , adults and pupae were frequently taken on corn, and on 
1st, both adults and young of several stages, some, evidently 
first, occurred at Effingham in fields of corn between the 
and stalk. September 25th, at Godfrey, adults were found 
igly preparing to hibernate under rubbish in the strawberry 
Imagos, with occasional pupae, were likewise found between 
isks of ears of corn.

story in time of peace hence does not differ materially from 
luring seasons of immense and wide-extended ravage.

army worm was not heard from anywhere as a notably in¬

as usual, in the course of our field operations. A fresh female 
was noticed May 3, having evidently just emerged from the

of wheat in the field. Transferred to a breeding cage, these

e information acquired during the last year is in the line of 
previously published, no case of considerable injury having 
observed by us or reported to me upon ground not recently in 
or two or more years. 
collections and observations also confirm the previous account 
life history as published in my first report. The earliest date 
appearance of the larvae in the earth, which we have our- 
noticed, is June 14, (1883). I found the larvae about half

ing the summer just past, less injury was done to corn than 
le previous seasons, owing to the wetness of the weather in 
summer, in consequence of which the affected corn rooted 
firmly and was able to maintain itself notwithstanding the
