CHINCH BUG ( Blissus leucopterus Say) 
Illinois 1. P. Flint and assistants (March 20): From 97 to 98 per cent of 
the bugs in winter quarters throughout southern and central Illinois 
are still alive. The winter has been milder than the average and 
only from 2 to 3 P er cent of the bugs died during the winter. T7e 
expect from moderate to heavy infestations in about 65 counties this 
spring. 
Nebraska M. H. Swenk (March 10): The chinch bug seems at this time quite 
threatening in the southern part of the tier counties along the 
southern border of Nebraska, from Jefferson County west at least to 
Furnas County, and in the northeastern corner of the State in Boyd 
County, the latter being a southward extension of a serious infesta- 
tion in southeastern South Dakota. 
Kansas E. G. Kelly (January 29): Chinch bugs seem to be more abundant than 
during average years. The temperatures have been above normal and 
very dry. Burning of hibernating quarters is being practised through- 
out .the State. 
HESSIAN FLY ( Phytophaga destructor Say) 
Nebraska M. H. Swenk (March 10): In spite of the dry summer and fall in 1922 
the Hessian fly seems to be still quite numerous in early-sown winter 
wheat in some parts of eastern Nebraska. A field in Dodge County 
examined in the middle of January contained on the average five 
puparia of this insect to each wheat plant. 
California C. M. Packard (March 7)* The Hessian fly is present in considerable 
numbers bordering San Francisco Bay, and in a region in the northern 
part of Monterey and San Benito Counties and the southern part of 
Santa Cruz County. 
GREEN BUG ( Toxoptera graminum Rond.) 
Kansas S. J. Hunter (January 15): Mr. Beamer has completed a survey of the 
southeastern tier of counties of Kansas and finds no evidence what- 
ever of the green bugs; this region, .owing to the unusual drought 
last August, had no volunteer grain. 
G. A. Dean and J. W. McColloch: Mild winter and a backward spring 
followed by excellent growing conditions have materially reduced the 
amount of green bug in the western part of the State,
