The Melanopli of Kansas. 



INTRODUCTION. 



This paper is the result of several years' study of the group of grass- 

 hoppers known as the Melanopli, belonging to the subfamily Acridiinae. 

 This group contains a large number of species of grasshoppers and in- 

 cludes nearly all of those of economic importance. The group is repre- 

 sented in Kansas by the following genera: Hypochlora, Campylacantha, 

 Hesperotettix, JEoloplus, Melanoplus, and Phcetaliotes. Thirty-nine 

 species are recorded here and are distributed under the six genera, as 

 follows : 



Hypochlora 1 



Campylacantha 3 



Hesperotettix 3 



yEoloplus 2 



Melanoplus 29 



Phcetaliotes 1 (two var.) 



The taxonomic side of the paper is based largely upon material col- 

 lected during the summers of 1910, 1911 and 1912 by the Kansas Uni- 

 versity entomological expedition while collecting material for the mu- 

 seum in central and western Kansas. A lot of material was also col- 

 lected during the summers of 1913 and 1914 while the writer, with five 

 other members of the Department of Entomology of the University, was 

 engaged in organizing the various counties for campaigns against the 

 native destructive grasshoppers in Kansas. 



The economic and biologic phases of the paper are based upon ob- 

 servations made at the time when economic work was carried on in the 

 western part of the state.
