 Acridium olivaceum Serv., Ortli., 666 (1839). 



This species has a more southern range than the preceding, from which 

 it is witli difficulty distinguished, not being known on the Atlantic coast 

 north of North Carolina, though in the west it occurs as far north as 

 Nebraska and even Iowa. It is not known west of eastern Colorado, 

 except in the south, where it occurs in New Mexico ; and it is found 

 throughout Mexico.
