ORDER XI, ORTHOPTERA. 



ON A COLLECTION OF NON-SALTATORIAL 

 ORTHOPTERA FROM PARAGUAY.* 



By a. N. Caudell, 

 Washington, D. C. 



For several years I have been receiving from Mr. W. T. Foster, 

 of Sapucay, Paraguay, numbers of Orthoptera taken by him within a 

 radius of ten miles of Sapucay. The U. S. Department of Agriculture 

 purchased about one thousand specimens from Mr. Foster and the U. 

 S. National Museum has acquired several hundred specimens from the 

 same source. These three collections are now deposited in the Na- 

 tional Museum and form the subject of this paper. 



It was my original intention to prepare a complete fauiaal treatise 

 on the Orthoptera of Paraguay but the lack of general collections from 

 various portions of that republic makes that impractical at this time. 

 I therefore present .the following as a contribution to the knowledge 

 of the Orthoptera of Paraguay. In subsequent papers I hope to treat 

 of the saltatorial forms represented in these collections. 



In the identification of these specimens I have been aided by the 

 works of Giglio-Tos and Brancsik, those of the former being especially 

 valuable as forming a list from which to work. 



A comparison of the species here treated with those recorded in 

 the various articles by Giglio-Tos in Boll. Mus. Torino shows the 

 fauna of the region about Sapucay to be quite different from that of 

 certain other portions of Paraguay. The country surrounding Sapucay 

 is described by Mr. Foster in a letter under date of May 14, 1902. 

 The following is quoted from this letter : 



"Sapucay is a small village situated at the base of a low table land 

 the elevation of which is 800 feet above the surrounding country. * * * 



* During the coming year I hope, with the cooperation of Dr. H. G. Dyar, to 

 promulgate a system of nomenclature with the hope of securing a comparatively stable 

 basis. Then a revised nomenclature will be adopted, in some cases agreeing with the 

 results arrived at by Krauss and others and in other cases radically different. But for 

 the present the old nomenclature is used.
