Distribution: This is one of our most abundant species. It 

 is found in every part of the state as shown by the following 

 map: 



Hosts: Feeds on a great variety of plants. Often is a pest 

 to crops because of its large numbers. Doctor Osborn records 

 it as feeding upon oats, timothy, corn, potatoes, and pasture 

 grasses. 



Genus BALCLUTHA Kirk. 



The members of this genus are rather elongate slender 

 species. The head is narrower than the pronotum and the ver- 

 tex is short, the margins nearly parallel. The elytra are very 

 long, greatly exceeding the abdomen, overlapping apically, 

 with a distinct appendix, and with only two anteapical cells. 

 The hind wings have only two apical cells. 



Only two members of this genus have been taken in Kansas.
