XVII. SOUTH AMERICAN LOCUSTS (ACRIDOIDEA). II. 

 By Lawrence Bruner. 



The present paper is based chiefly on a rather extensive collection 

 of these insects made by J. Steinbach in eastern Bolivia and south- 

 western Brazil, a region but little explored heretofore. Other material, 

 however, is also at hand and included that was taken by J. D. Haseman 

 and one or two other collectors in the employ of the Carnegie Museum. 

 A few of the insects, here reported also, are some that were set aside 

 for further study during the preparation of my two former papers 

 published in these Annals. As stated in the preface to my last 

 paper (Annals. Vol. VI 1 1) reports are also in the course of preparation 

 by me treating both the Grylloidea and Phasgunurids or long-horned 

 grasshoppers, taken by the same collectors and in the same territory. 

 Of these latter there are likewise apparently many new forms. 



As in the former reports a number of synoptical tables of genera 

 and species are included where it is thought they will materially aid 

 the student in the recognition of these insects.
