Michigan. R. H. Pettit, (March 1"5. ) , ' "Chinch, bugs nave gradually "bee ome common 
in the lower tier of counties next to Ohio and Indiana. The present 
open winter has shown them to he quite numerous on the -under sides of 
mull en leaves and similar plants. We have been fortunate in the past 
in having been almost free from serious chinch bug attacks but expect 
to have to deal with them during the coming season. " . • 
Illinois. Expansion Ne\vs Letters. Issued oy the Extension Entomologists (March 
30,). "Damage expected in fifty counties; severe in thirty. Wintered 
exceptionally well. . A few bugs flew .on. March 19 and 20 in. Southern 
part of State. Resistant strains' of corn will be generally grown in 
infested area."

W.. P. Flint, (April 16). "The mild winter has been favorable to hiber- 
nating bugs. The insect is abundant over a- greater area in the State 
than any time since 1887. Damages expected in fifty counties, severe 
in 30. A few bugs flew into the wheat on March 19 and 20. Moderate 
flights have occurred on several days since. Not more than half of 
the bugs are now in the wheat." 
J. J. Davis, (April 15). ' "Chinch bug' was not reported by. correspond- 
ents to the Experiment Station in the year 1917, a number reported 
damage in 1918, more than twice as many in 1919,' and more than four 
times as many in 1920. Forty-six counties in Indiana are infested, 
one-third of which might be considered as dangerously infested. The 
infestation begins at the extreme northeastern corner of the State and 
moves in a diagonal strip through the State several counties wide, the 
heaviest infested counties being in the northeastern and south-western 
tier of counties. The central part of the State is less heavily infes- 
ted and the north-vest' and southeast corners are almost entirely free 
of bugs. There is every indication that the chinch bug will be a ser- 
ious and important pest this year and more severe and widespread than 
for many years . "

Myron H. Swenk, (April 15,). "In 1.920 there was some damage of a ser- 
ious sort to wheat and corn in the Southern parts of Nuckolls and Tha- 
yer counties. They wintered in rather larger numbers than usual in 
Southern Thayer County and probably west to Franklin County and in
