I. SALTATORIAL ORTHOPTERA FROM SOUTH AMERICA 

 AND THE ISLE OF PINES. 



By Lawrence Bruner. 



Introductory. 



The following pages relate to a rather considerable number of 

 saltatorial Orthoptera collected for the Carnegie Museum in Argentina 

 and Bolivia by Mr. Jose Steinbach, and in French Guiana and the 

 State of Para, Brazil, by Mr. S. M. Klages. A few species from the 

 Isle of Pines, collected by the late Mr. G. A. Link, Sr., and his asso- 

 ciates, are included in the report. The latter were obtained some 

 years ago, but the collections made by Mr. Steinbach, and those 

 made by Mr. Klages, have come into the possession of the Museum 

 in quite recent years. The writer in the spring of 191 9 was prepared 

 to submit a report upon those parts of this assemblage of insects which 

 had at that time come into his hands, but the receipt of later col- 

 lections made in the remote interior of French Guiana and about Para 

 by Mr. Klages, seemed to make it preferable to withhold this report, 

 until the more recently acquired material could be studied and the 

 results of such investigation incorporated with what had already 

 been written. This was a fortunate decision, as the material alluded 

 to, which was received by the Museum in the summer of 1919, proved 

 to be rather interesting, and to contain a number of apparently 

 undescribed forms. Every sending of insects from the little-visited 

 parts of tropical America reveals the fact that our knowledge of the 

 fauna is not yet complete. In the papers upon the Orthoptera of 

 the American tropics, which the writer has presented in the pages 

 of the Annals of the Carnegie Museum, including the present report, 

 there have been described over two hundred and sixty (264) species 

 new to science. The types of these species are of course all preserved 

 in the Museum in Pittsburgh, where they may be consulted by future 

 students of the order. 



In this, as in former papers by the writer issued by the Carnegie 

 Museum, synoptic keys of the species in a given genus have been
