8 INSECTS INJURIOUS IN 1902. 
have been called upon so often this season to demonstrate the sim- 
ple and effective means of preventing injury to corn and in some 
cases to describe such a generally well known insect. 
It has been reported this season from Belgrade, St. Augusta, 
Luxemburg, Carmody, Kimball, Wyoming, Hedrum, Haven Prai- 
rie, Big Lake, Fotest City, Litchfield, Cambridge, St. Francis, 
Osseo, Anoka, Farmington, Cedar Mills, Elk River, Mora, Brad- 
ford and Lynd, representing the following counties: Stearns, 
Isanti, Chisago, Dakota, Sherburne, Meeker, Kennebec, Lyon, 
Anoka, Hennepin, Wright and Waseca. The majority of com- 
plaints came from the counties of Stearns, Isanti and Meeker in

the order given. A line starting at Mora and running southwest 
to Benson and then south to the Iowa boundary would appear to 
mark the northern and western limit of affected localities in this 
state. I have not this season (barring an unsubstantiated rumor 
that a few occurred in the sandy portions of Douglas county) been 
able to detect it north or west of the above mentioned line, though 
doubtless there were many affected localities from which I did 
not hear. 
Consulting the late Dr. Lugger’s reports of ‘95 and ’96 I note 
that he claims that in 1887, besides many other places, they also 
occurred in Pine, Crow Wing, Hubbard, Wadena, Todd, Morri- 
-son and in ’95 and ’96 in Morrison, Otter Tail and Douglas coun- 
ties lying to the west or north of the boundary I have indicated. 
In 1895 also it is given as “reported” at Vermilion Lake.
