edges of the more open forests. These insects are rather small and 

 inconspicuous, being graj and dull brown in color. Living, as they 

 do, among the litter on and near the ground, they arc fairly well pro- 

 d from birds and other vertebrate enemies, hence are the common 

 "grasshoppers'" in their respective regions. Ai leasl seven species 

 have already been recognized, and a careful stud} of these insects 

 throughout the regions, where the genus occurs, will no doubt add 

 >e\ eral others.
