Notes on Paraguayan Orthoptera, with Descriptions 



of a new Genus and Four new Species. 

 BY JAMES A. G. REHN, Academy of Natural Sciences, 



Philadelphia, Pa. 



The following notes and descriptions are based on a small 

 but very interesting collection of Orthoptera submitted to me 

 for study by the well-known naturalists, A. de Winkelried Ber- 

 toni and Prof. C. Schrottky, of Puerto Bertoni, Paraguay, 

 from which locality the greater portion of the material was se- 

 cured. Prof. Bruner has already reported* on a collection of 

 Acridoidea from this locality.

 Pyragra brasiliensis (Gray). 



Puerto Bertoni. One female (Schrottky).

 ly smaller than the original measurements of the species, but 

 otherwise it is typical.
