some wheat light weight. Smithboro, July 10. “Destroying corn” 
Report similar to that at Greenville. Chief injury to corn. * aes 
Monrcomery.—Litchsield, May 27. Found bugs in most wheat fields | 
along the road for four miles south of town, Wheat damaged most on_ 
corn ground and in the vicinity of places where corn shocks had stood. 
over winter. Eggs abundant; a few young bugs. June 2. Few eggs seen; ~ 
young bugs very numerous. From ten to fifteen per cent. of wheat in 
vicinity where corn shocks stood is ruined. July 18. Chinch bugs very 
abundant in and near woodlands on gray soil. Scarce on black lands: 
north of them. Several rows of corn killed in many fields adjoining small 
grains. Scattered traces of insect disease, but not sufficient to promise | 
any important aid. Sept. 28. Bugs collected in corn fields. Every field — 
entered contained bugs enough to excite apprehension for next year. Ph 
Suetry.—Herrick. Aug. 24. Second brood of chinch bugs will seriously © 
damage corn; many stalks completely covered. Shelbyville, Nov. 15. Bugs | 
present in considerable numbers. Injuries mostly confined to corn, hoe | 
CHRISTIAN. —Morrissonville, July 4. “Leaving wheat for corn. Threaten © 
great damage.” Taylorville, Nov. 17, General diffusion of bugs reported. — 
Some wheat reduced to light weight; corn next wheat fields injured. Y 
Macon=—Blue Mound. May 25. Corn and wheat infested by chinch bugs. 
June 27. Bugs of all ages, mostly young, present. A quart can nearly | 
full of them sent to the office. ! i 
In addition to the above list, a general diffusion of chinch bugs was | 
also reported, at this time, with little or no injury, from the counties of 
Brown, Champaign, Coles, Macon, Sangamon, Effingham, Macoupin, Btw 
Clair, Jefferson, Wayne, Clark, Lawrence, Edwards, White, Hamilton, 
Randolph, Pope, and Johnson. 
St. Clair, Washington, Clinton, and Montgomery counties reported — 
the bugs as being present in small numbers in 1890 also, A noticeable | 
feature of the injury to wheat in this part of the State is that it suffered 
greater damage in the immediate vicinity of corn shocks, where the 
shocks were permitted to remain over winter. } 
In northern Illinois trips of investigation made later im 1891 
showed the bugs to have been destructive locally in some nine counties 
for two years, and in a few places for three. Spring wheat, rye, and— 
barley have afforded them the most acceptable breeding places. Destruc-_ 
tion of these grains in areas varying from a fraction of an acre up to- 
two. three, or more, acres was common all through the infested region ;_ 
and spring wheat was frequently light in weight because of the attacks — 
of the bugs. Oats were quite generally infested, but did not suffer so- 
severely as the other small grains, only now and then a small area show-— 
ing noticeable injury. Corn next to spring wheat, rye, or barley, suffered 
considerable damage, several rows next such fields often being almost | 
wholly worthless. Fields at a distance from the small grains contained 
bugs in limited numbers scattered all through them, but were not com-_ 
monly damaged noticeably. The situation in these northern counties” 
in the summer and fall of 1891 is shown more specifically in the fol- 
lowing brief abstracts of field notes and correspondence : i 
McHenry.—Marengo, Oct. 15. Second year of appearance, Great dam-_ 
age to rye, oats, and corn; some rye and corn not harvested. Woodstock, 
Oct. 16. Abundant all over the county. Wheat, corn, and barley attacked; | 
corn not much hurt. Damage greater than last year. 
Boone.—Belvidere, Oct. 15. Bugs reported five miles from town, where 
rye was being plowed up because of them. 
WINNEBAGO.—Rockford, Oct. 17. Abundant all through this region, Rye | 
not much harmed; barley severely attacked; wheat and corn attacked vari-—
