on specimens from these situations, and since most of tlie 

 species found in them are of very general distribution in more 

 natural habitats which are ecologically similar, no attempt at 

 classification of these purely artificial habitats has been made. 

 Here were taken the following species : 



Arphia sulphurea (stubble fields). 



Chortophaga viridifasciata (clover and hay fields). 



Dissosteira Carolina (cultivated, stubble, and wheat fields). 



Bncoptolophus sordidus (cultivated, stubble, and wheat fields). 



Spharagemon holli (stubble fields at margin of woods). 



Spharagemon collarc zvyomingiaiium (stubble and wheat fields, 



orchard). 

 Melanoplus bivittatus (stubble, grain, and hay fields). 

 Melanophis differentialis (stubble and wheat fields). 

 Melanoplus fcmur-ruhrum fcviiir-rubrum (grain, hay, clover, and 



stubble fields). 

 Melanoplus keeleri luridus (stubble fields). 



Melanophis mexicanns atlanis (of almost universal occurrence). 

 Scudderia texensis (weed-grown stubble field). 

 Scudderia fnrcata fiircata (orchards, on tall weeds and tree 



branches). 



EdiUcarian habitat. The following species of Orthoptera 

 were taken in buildings at the Warren Woods, Three Oaks, 

 New Buffalo, or in the dune region :
