grass zones along the lake shore. Several specimens were col- 

 lected in open oak woods at New Buffalo and in the Sawyer 

 Dunes ; one was taken in a molasses trap in thick forest, 

 together with Blattids and Ceuthophilus. Several, both of 

 the long- and short-winged types, were taken at light. This 

 species is frequently found under boards, stones, and other 

 objects in the fall, congregated together in colonies ; on August 

 31 several hundred individuals were found under the loose 

 bark of a single stump in the grassy margins of Warren 

 Woods. A number of specimens were taken at night, in com- 

 pany with several species of Melanoplus and other forms, 

 resting on tall mullein stalks and other plants, often three 

 feet or more above the ground. Other specimens were found 

 in cottages among the dunes and at the Warren Woods, where 

 they had apparently taken up their residence, since they could 

 be heard stridulating in the same corner night after night. 



But little correlation of the various forms with specific hab- 

 itats was noted. The typical neglectus variant was not taken 

 in any of the drier habitats; it was commonest in the low, 

 open, grassy woods found on some parts of the Galien River 

 flood-plain, and among the low herbage around the shores of 

 some of the dune ponds. The pennsylvanicus variant is the 

 most widespread : this was the only one found in the beach 

 grass and bunch grass zones of the dune region, and it occurs 

 in all of the other situations enumerated above. The luctuosus 

 variant is less common than pennsylvanicus, though found 

 with it in the same habitats. The only specimen secured refer- 

 able to scudderianus was taken on the lake strand. The pro- 

 portion of macropterous individuals for the dune region is 

 high, due largely to the fact that a considerable number of 

 the specimens were taken in the beach drift ; all of these are 

 macropterous with the exception of one male. This was prob-
