ON BRAZILIAN GRASSHOPPERS OF THE SUBFAMILIES 

 PYRGOMORPHIN^ AND LOCUSTIN^ (ACRIDIN^ OF 

 AUTHORS). 



By James A. G. Rehn, 



Of the Academy of Natural Sciences of Philadelphia. 



The following study is based upon a series of one hundred and 

 ninety-two specimens of Brazilian Pyrgomorphinae and Locustinge 

 belonging chiefly to the collection of the United States National 

 Museum. Fifty-three species are treated in the paper, of which sev- 

 enteen are new, four new genera also being described in these pages. 



Of the series studied by far the greater portion is from the collec- 

 tions made by Mr. H. H. Smith in the State of Matto Grosso and at 

 Rio de Janeiro, while a smaller series, taken by Mr. A. Koebele in 

 northeastern Brazil in the States of Pernambuco and Bahia, is even 

 proportionately more interesting. 



My acknowledgments are due the authorities of the National 

 Museum for their kindness in permitting me to examine the museum 

 material. My thanks are here given also to Mr. Morgan Hebard, 

 from whose collection was received for study a portion of the series 

 here treated.
