INTRODUCTION. 



The third annual report of the Entomologist of the 

 State Experiment Station of the Tniversity of Minnesota, 

 respectfully submitted to His Excellency, Governor D. Al. 

 Clough, contains an account of all such Orthopterous 

 insects as Locusts, Grasshoppers, Crickets, Cockroaches 

 and others which occur in our state, and which have proved 

 so destructive in the past, and are ever ready to cause severe 

 losses in the future. Other work only commenced or partiv 

 finished will be suljmitted later. 



There remains ior the entomologist the pleasant duty 

 of expressing his sincere thanks to all persons that have 

 aided him in man\^ ways in his work. Especial thanks are 

 due to the different newspapers, who with unfailing courtesy 

 published all articles written for the instruction of the 

 farmers in regions infested by injurious insects. The Chicago, 

 St. Pnul, Minneapolis & Omaha, the Great Western, the St. 

 Paul & Duluth, the Northern Pacific, the Minneapolis & St. 

 Louis, and the Great Northern R. R. Companies also deserve 

 thanks for their liberality in furnishing free transportation 

 over their roads whenever such was asked.
