Bruner : South American Acridoidea i:> 



lection coming from any pari of thai country contains both m-u genera 

 and species. The presenl collection, as will 1>c observed by an 

 examination of succeeding pages, furnishes a very fair quota of such 

 forms. 



\\ hen we consider the comparatively small tracts and few -■■< tions 

 ol thai vasl country, which have been \isited and explored by collec- 

 tors, as compared with the portions, which still remain unexplored, 

 we cannot avoid wondering what the great forests and swampj 

 districts of the tropics will yield to the votaries of science in tin 

 of future discoveries in the family. 



Ii had been the intention of the writer at this time to present a care- 

 fully prepared synopsis of the South American genera of this family. 

 A dearth of the proper material and lack of sufficient time has, however, 

 necessitated its postponement to some future date. 



Genus Prionolopha Stal. 

 Prionolopha StAl, Recens. Orthopt., I, p. 27 (1873). 



The presenl genus was erected for the reception of the Gryllns 

 ( Bulla) .scrr.it us of Linnaeus, which occurs throughout most of tropical 

 America. According to ort hopterologists there is but a single species 

 recognized, although main- synonyms have been created by the 

 description of supposedly distinct forms.
