]C) THE CHINCH BUG. 
bug might have been, in early days in the Mississippi Valley, kept 
up to a high standard of development by the necessity of such an 
escape from prairie fires and not by the presence of Sporotrichum 
globuliferum^ as suggested by Professor Sajo in his paper, a trans- 
lation of which is included herein under the heading, " Habits of 
the European species, Blisms dories Ferr." 
A.s mentioned farther on, the advance of civilization having revo- 
lutionized the face of the country, there has conic a corresponding 
change in the hibernating habits of the chinch bug. This insect 
must now seek shelter in the limited patches of timber that are left 
in the sections that were cure entirely wooded and in the matted grass 
along fences and roadsides, but especially among the fallen leaves 
and rubbish that usually accumulate along Osage orange hedges. 
Brush piles, old haycock-, strawstacks, and. in Ohio, at any rate. 
shocks of corn fodder left standing in the fields through the winter, 
all harbor chinch bugs during the hibernating season. 
The fact that the insect hibernates in matted bluegrass along road- 
sides and fence- has been called in question by Professor Forbes and 
by Mr. Marlatt, the former in his first report as State entomologist 
of Illinois (p. 37) and the latter in Insect Life (Vol. VII. p. 232), 
but notwithstanding this, in some parts of Ohio, in Indiana, and 
Qlinois they do hibernate in just such places and can be found there. 
especially during the winter and early spring following a season of 
abundance, but the investigator must know how to search for them. 
The writer has found them late in the fall collected under rail-, half 
buried in -oil and dead grass, and in northern Illinois, while search- 
ing for other insects in early spring, he was sure to find them in vary- 
ing number- with -mall Carabidae, Staphylinidse, and other early 
appearing insects, on the under side of boards laid down in grassy 
place.-, though no amount of searching the grass itself would have 
iv\ ealed their presence. 
In the timothy meadow- of northeastern Ohio the percentage of 
long-winged individuals i- always much greater in fall than in June. 
showing that some, at least, hibernate there and migrati to the cul- 
tivated fields in spring. In Maine, in the case of the maritime form. 
of 565 bug- collected in hibernation in October, 1002. only 60 had long 
wing-. In Kansas, where Mr. Marlatt made his observation-, there 
was -till too much prairie, and the species was doubtless still adhering 
to it- ancient habit- of hibernation. In southern Ohio the author has 
found it attacking the wheat in May. in -mall isolated -pot- over 
the fields, while there was nothing in the least to imply an invasion 
from outside, but the wheat had been sown in the fall among corn, 
and later the cornstalks cut oil' and -hocked, remaining in this condi- 
tion until the following spring. This occurred so frequently that
