more abundant in west-central Ohio and the northern two-thirds of Indiana. 
The fall surveys indicate that it has increased from 1.5 per cent in 1925 
to 3.6 per cent in 1926 in New York State and from 7.5 per cent to 8.8 per 
cent in Ohio; hut in Illinois the fall surveys indicate a decrease in the 
abundance of this insect. In general, the fly is not appearing in threatening 
numbers east of Kansas. A rather unusual situation developed in Pennsylvania, 
where the flies in volunteer ^heat emerged this fall, infesting grain sown 
after the fly-free date. Usually these flies do not emerge until the following 
spring. Another interesting development of the year was the discovery of this 
pest on the east coast of Hew Brunswick, in Northumberland County, about 100 
miles from the St. Johns River Valley. 
Brood ,f A" of white grubs emerged as prognosticated. Heavy flights were 
observed during May in southern Illinois, parts of Indiana, Iowa, Missouri, 
Kansas and Mississippi, Hie larvae of these insects xvere in general less 
prevalent and destructive than usual in the United States, but in southern 
Ontario the damage caused by them seems to have materially increased over 
that in 1925. 
The chinch bug passed the winter with slight mortality. During May it 
was reported as unusually abundant in central and south-central Illinois 
and in parts of Kansas. The outbreak in Mississippi reported last year does 
not seem to have abated. In general, however, damage by the chinch bug 
was not serious, although scattered outbreaks were reported from Mississippi, 
and rather intense infestations from southeastern and southern Nebraska, parts 
of Kansas, and central Missouri. Owing to the lateness of the season the 
movement of the chinch bug from small grain to corn was delayed until early 
in July. At that time the situation seemed rather serious in the Ohio River 
Valley and westward to Nebraska and Kansas. Heavy rains in the last however, 
materially checked this insect, and present indications are that in the Ohio 
River Valley it will go into hibernation in materially reduced numbers; in the 
part of the chinch bug belt west of the Mississippi River it will in all 
probability enter the winter in large numbers. 
The green bug ( .Toxoptera ^raminum B ond. ) appeared in March in -only small 
and localized areas in the southern part of its range; small areas were found 
infested near Sherman and Rochelle, Tex. Early in April a single outbreak 
was reported from Logan County, Okla. In the northern part of its range, 
however, in Ohio, Indiana, Michigan, Minnesota, South D a kota, Wisconsin , and 
Iowa, it appeared in rather conspicuous numbers, but the damage except in 
Minnesota was not serious. 
Grasshoppers in general were not in 1926 unusually abundant in the United 
States. In British Columbia, however, serious outbreaks occurred, particularly 
in the Peace River and Chilcotin districts. 
Wireworms (Slateridae) were reported from many scattering localities. 
No unusually serious damage, however, was recorded from the United States. In 
the Provinces of Saskatchewan and Alberta these insects have since 1923 
continued to increase in both numbers and importance as crop pests.
