A FURTHER CONTRIBUTION TO THE KNOWLEDGE OF THE 

 ORTHOPTERA OF ARGENTINA. 



BY JAMES A. G. REHN. 



In these Proceedings there recently appeared a paper by the 

 present author entitled, "A Contribution to the Knowledge of the 

 Orthoptera of Argentina. "' This study was based wholly on material 

 collected by Mr. P. Jorgensen, of Buenos Aires, and submitted to us 

 for study by that gentleman and Mr. Esben Petersen, of Silkeborg, 

 Denmark. Since the appearance of the above-mentioned paper, 

 several additional collections from Argentina, made almost wholly 

 by Mr. Jorgensen, have been received from the same persons and, 

 in addition, a small but very interesting series from Mr. Carlos Lizer, 

 of Buenos Aires. 



The combined material represents quite a few localities supple- 

 mentary to those given in the previous paper, while thirty-eight 

 species are additional to the one hundred and sixty-two there 

 discussed. 



The total number of species here treated is one hundred and four- 

 teen, of which nineteen are now recorded from Argentina for the 

 first time, while three species are new to science. The number of 

 specimens in the present series is four hundred and fifty-eight. 



In the tabulation given on page 275 of our previous paper, there 

 can be added to the forty-nine species known in Argentina only from 

 the Misiones Territory, ten of the eighteen here first recorded from 

 Argentina. This is directly in line with the previously indicated 

 evidence of the richness and Brazilian affinity of the Misiones region. 



The forms here first recorded from Argentina are indicated by an 

 asterisk preceding the specific name. 



The types of the new species and an adequate representation of 

 the other forms in the collection have been retained for the Academy 

 series. We wish to thank Messrs. Jorgensen, Lizer and Petersen for 

 their interest and courtesy in submitting the present material to us 

 for study.
