Rather generally distributed, but only locally common. It 

 was taken in rather large numbers in a strip of short, dry 

 grass along the top of a steep bank overlooking the Galien 

 River, on the Warren Woods Preserve. It was also common 

 in dry grass among the shrubbery in a field of second growth 

 scrub and in sandy clearings with a sparse growth of dry grass 

 among the dune woods. Specimens were taken in the grassy 

 margins of open woodland and dry bluegrass pastures. On 

 certain occasions it was fairly common in the insect drift along 

 the shore of Lake Michigan. 



In this region the species begins to mature about the middle 

 of June ; on the twenty-third of that month adults were few and 

 mostly teneral, but last stage nymphs were abundant. It is 

 still common the first week in September. Hancock records 

 specimens found during August at Lakeside.

The commonest of the bare-ground locusts. Found every- 

 where on roads, cultivated fields, stubble fields, pastures and 

 fields of sparse dry grass, bare patches trampled by cattle, et>:. 

 It is fairly common among the beach grass and bunch grass 

 on the lake shore, and is found in grassy openings in the dune 

 woods. Specimens were also taken in a moist meadow pasture 

 and among the grass and herbage on a springy hillside near 

 the Warren Woods Preserve. Three males were taken in a 

 wet sedge marsh in a cleared ravine on the preserve, where
