The following records have been made from a small collec- 

 tion of Orthoptera taken at Sapucay, Paraguay. The mate- 

 rial is the propert}' of Mr. Morgan Hebard of Chestnut Hill, 

 Philadelphia.

 tina and the Bolivian Chaco.

These specimens agree with a female individual from Para-

 female from Brazil and Rio Grande do Sul received from Dr. 

 Saussure. One of the Sapucay specimens is blackish brown 

 in color with the maculations rather faint, the other is wood 

 brown, the anal area of the tegmina pale, the maculations of 

 the tegmina barely visible. Originally described from ' ' Bresil, ' ' 

 this species has since been recorded from Buenos Ayres and 

 the province of Jujuy, Argentina, Caiza in the Chaco of 

 Bolivia and Asuncion, Paraguay.
