This fine large grasshopper is probably the species which has been 

 destructive to vegetation in the valley of the Great Salt Lake. It is 

 nearly as large as the destructive (Edipoda migratoria (with which it 

 is congeneric). The last-named species is known under the English 

 name of "migratory locust."

 and blue-legged variety, the extremes of which have been named dif- 

 ferent species in the past. A large series of these 'hoppers show all 

 degrees of variation from one extreme to the other.
