LETTER OF SUBMITTAL. 



Li\( oln, Nebr., November ... 1893. 



Sir : I submit herewith a Bhort report apoo my investigations among the injurious 

 insects of Nebraska and adjoining districts during the past summer. While these 

 pests have not been generally numerous and destructive over the region assigned 

 me. a few species from among the hosts of these creatures that are ever present have 

 been sufficiently abundant to commit injury to the crops attacked and to require 

 special attention on the part of the entomologist and agriculturist. Some of my 

 time has also been given to a further study of destructive locusts and allied ii- 

 belonging to the order Orthoptera. in which I have been especially interested for 

 some years. For this purpose three separate trips were made into quite distinct 

 regions, viz, one to Colorado for the purpose of investigating a local locust outbreajc 

 about the town of Grand Junction, a second to western Nebraska and eastern Wyo- 

 ming to examine into a reported appearance of the Rocky Mountain locust, and, 

 lastly, a -hort tour of inspection through the eastern and central parts of Nebraska 

 for the purpose of ascertaining exactly how numerous and extensive were the inju- 

 ries caused by the " native *' species of locusts that had been reported as committing 

 havoc with various garden truck, small trees, grape-vines, and also in some instances 

 field crops. 



Many of the notes made on other insects than locust-, and in fact some of the lat- 

 ter also, were obtained in connection with work carried on at the University of 

 Nebraska or while engaged in held work for this institution. These latter are sub- 

 mitted herewith as of some possible value to the general public aside from citizens 

 of the State. 



Very respectfully, yours,

LOCUSTS OB "GRASSHOPPERS. 



The past summer again has been noted as one in which the various 

 species of indigenous locusts were present in overwhelming numbers 

 over a large area of country. The injuries wrought by these insects 

 were, therefore, great and widespread. Reports bearing on the subject 

 were received from a number of correspondents located in this and 

 adjoining States. The newspapers also contained like reports, from 

 all of which it becomes quite evident that something definite in the
