This species has been found by our parties in various parts of Utah 

 and Colorado, although it appears to be not so common as at the East. 

 The thickets by the water courses and the damp meadowy grounds of the 

 lowlands are its places of resort. In Arizona, it appears to be rare; and I 

 have met with it but twice, at Camp Apache, and again at Camp Grant. It 

 is a summer resident.
