Ilabitat. — Paraguav, January 25, 1901.

 obliquely truncated posterior angles of the lateral lobes of pronotum. 



PARATETTIX Bolivar. 

 PARATETTIX SCHOCHII Bolivar. 



Paratettix schochii Bolivar, Essai Tettigidae, 1887, p. 100. 



This insect is credited to Asuncion, Paraguay, by Giglio-Tos. It is 

 quite possible, however, that this is an error and another insect is 

 referred to.

 at hand from that country.
