INTRODUCTION. 
The sixth annual report of the Entomologist of the 
State Experiment Station of the University of Minnesota, 
respectfully submitted to His Excellency, Governor John Lind, 
contains an account of bugs found in Minnesota, which in 
their different stages are destructive to our various kinds 
of crops, and which frequently cause very great losses to the 
farmers and fruit growers. 
It was, however, impossible to describe all the numerous 
and destructive insects, belonging to the Order of Hemiptera, 
or Bugs, but as the species not described in the following 
pages are similar in shape and habits to those mentioned, 
it will not be difficult for the intelligent farmer to select the 
proper remedies against them. Remedies are given in every 
case and if applied a large amount of injury and consequent 
loss may be prevented. 
It would perhaps have been best to have the insects de- 
scribed in this report arranged according to their food- 
habits, but to make it also useful to students of our public 
schools, etc., the insects are arranged according to the classi- 
fication of Hemiptera usually adopted, and the different 
families have been described in a few words. The illustra- 
tions will assist greatly to discover the name of the culprit, 
so that those interested in such matters will find it easy to 
consult other publications to learn more about their habits, 
etc., as could be given in one report. 
There remains for the Entomologist the very pleasant 
duty of expressing his sincere thanks to all persons that 
have aided him in many ways in his work. Especial thanks 
is due to His Excellency, Governor John Lind, who always 
took great interest in the work of the Entomologist, and 
also to the different newspapers, who with unfailing court-
