2 Uiiii'ersity of Michigan 



Berrien County lies in the southwest corner of the state, 

 bounded on the south by Indiana and on the west by Lake 

 Michigan. Here the writer, as a member of the Michigan 

 Geological and Biological Survey, carried on field studies on 

 the Orthoptera during the early summer and fall of 19 19 and 

 1920; four visits were made to the region, amounting in all 

 to about six weeks. R. F. Hussey accompanied the writer on 

 the first three of these occasions, and also worked among the 

 dunes along the lake shore during the entire month of July, 

 1920. The most important part of the seasonal range of the 

 group was thus covered ; but no collecting was done during 

 the spring or late fall, which would vuidoubtedly have added 

 a few species to the list. 



During the course of the work the writer became deeply 

 indebted to a number of persons. Much of the success of the 

 field work was due to the interest and cooperation of George 

 R. Fox, Curator of the Chamberlain Museum of Three Oaks, 

 who placed his detailed knowledge of the region and a con- 

 siderable portion of his time at the disposal of the party, 

 besides furnishing transportation and aiding the work in many 

 other ways. Mr. Hussey added to the burden of his own 

 studies on the Hemiptera that of collecting a large series of 

 Orthoptera in the dune region during the latter part of July, 

 which furnished the basis for some records which would not 

 otherwise have been obtained. To Mr. Carrol Rawclifi^e the 

 writer is indebted for the gift of a number of specimens. 

 Mr. James A. G. Rehn and Mr. Morgan Hebard kindly deter- 

 mined a number of the species here recorded, and verified the 

 author's determinations of a number of the more difficult 

 forms. 



All of the specimens recorded in this paper are deposited
