b. On loamy and clay soils. Examples of this habitat were 

 studied in the cleared portion of the Warren Woods Preserve 

 and in the vicinity of Three Oaks. On these areas the blue 

 grass {Poa pratensis L. and compressa L.) is the dominant 

 plant, growing to a height of about eighteen inches. Asso- 

 ciated with it are occasional thistles, several other species of 

 grasses, yarrow, mullein, and a few other plants. This habitat 

 is heavily pastured on the preserve, and throughout the region 

 is most frequently found in the form of pasture land. During 

 the greater part of the season this habitat is very dry, the 

 grass being withered and brown by the first of July and remain- 

 ing so during the rest of the summer and autumn. Here the 

 following species were taken : 



Nomotettix cristatus, probably Mclanoplus confnsus^

Pine dune habitat. Near Sawyer the crests of some of the 

 dunes of the lake series are covered with an irregular growth 

 of juniper and yew, the sand between the shrubby trees being 

 covered with grasses and vines. No collecting was done in 

 this habitat. 



.Small open groves of white pine are found here and there
