their winter quarters. On the 16th, adults were noticed at the bases 

 of the plants in rye fields, (doubtless engaged in laying their eggs), 

 and also at the bases of the stalks of sprouting corn. On the 19th, 

 at Danville, they were likewise seen at the bases of stalks of wheat, 

 and were taken by sweeping the meadows. In the former situation 

 they were several times observed in coitu. On the 22d, considerable 

 numbers, ail adult, were obtained from rye. No young could be 

 detected, although the adults were frequently paired. The latter 

 were also occasionally numerous in corn fields. On the 24th, they 

 were taken frequently by sweeping oats, and likewise found coupled 

 about the roots of corn. On the 5th July, the young were noted 

 frequently at bases of stalks of rye in fields at Normal, and on the 

 20th, were seen occasionally on corn beneath the sheaths. August 

 4 to 11, adults and pupae were frequently taken on corn, and on 

 the 21st, both adults and young of several stages, some, evidently 

 of the first, occurred at Etfingham in fields of corn between the 

 leaves and stalk. September 25th, at Godfrey, adults were found 

 seemingly preparing to hibernate under rubbish in the strawberry 

 fields. Imagos, with occasional pupte, were likewise found between 

 the husks of ears of corn. 



From the above we may infer the usual existence of two broods 

 and at least the occasional occurrence of a third, even in those 

 seasons when the results of their multiplication are relatively in- 

 significant, and the insects themselves escape general notice. Their 

 life history in time of peace hence does not differ materially from 

 that during seasons of immense and wide-extended ravage. 



The ARMY WORM was not heard from anywhere as a notably in- 

 jurious species, although occasional individuals were noticed in the 

 corn, as usual, in the course of our field operations. A fresh female 

 moth was noticed May 3, having evidently just emerged from the 

 chrysalis. On the 27th May, mature larvae were found feeding upon 

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

 entered the earth June 7, one emerging June 28, and the other 

 July 7. 



The CORN ROOT woRBi (Diabrotica longicornis) , has continued its in- 

 juries to the staple crop of the State, interrupted only by the grow- 

 ing disposition to practice rotation of crops as a remedy against it. 

 All the information acquired during the last year is in the line of 

 that previously published, no case of considerable injury having 

 been observed by us or reported to me upon ground not recently in 

 corn for two or more years. 



Our collections and observations also confirm the previous account 

 of its life history as published in my first report. The earliest date 

 of the appearance of the larvae in the earth, which we have our- 

 selves noticed, is June 14, (1883). I found the larvae about half 

 grown in fields of corn near Polo, in Ogle county. 



During the summer just past, less injury was done to corn than 

 in some previous seasons, owing to the wetness of the weather in 

 early summer, in consequence of which the affected corn rooted 

 more firmly and was able to maintain itself notwithstanding the
