I. SOUTH AMERICAN ACRIDOIDEA. 



By Lawrence Bruner. 



The presenl paper follows thai published in November, 1910, in 

 the Seventh Volume of these Annals entitled "South American 

 Tetrigidae." Both that and this are reports on portions of the ex- 

 tensive collection made by H. H. Smith and owned by the Carnegie 

 M Liseum. 



While the account of the grouse-locusts here referred to was made 

 rather complete for the whole continent, it is impracticable to continue 

 the same style of treatment for the remaining families of South 

 American Acridoidea. Accordingly with few exceptions only the 

 actual material at hand will be noted. Nevertheless several synoptical 

 tables of the species of important genera are included, where it is 

 i houghl such additions will prove helpful to orthopterological students, 

 while studying the insects belonging to the fauna of South America. 



The types of the various species now described are, with few excep- 

 tions, the property of the Carnegie Museum. The others are in the 

 collection of the writer. 



Additional reports on this same collection of Orthoptera are in 

 course of preparation and will appear later. These include representa- 

 tives of the Grylloidea and Locustoidea (Phasgoneuroidea). 



The arrangement or sequence of the various families and genera 

 as found in the following pages, while not exactly in accord with my 

 conception of the classification of these insects, follows rather closely 

 that of W. F. Kirby as contained in his Synonymic Catalogue of 

 Orthoptera, Vol. III. 1 



Family EUMASTACID^E. 



But few representatives of the Eumastacidce are at hand, although 

 the group is practically tropical in its distribution. Only two genera 

 are found in the material before me.
