Genus Tropidacris Scudder. 

 Tropidacris Sodder, Proc. Bost. Soc. Nat. Hist., XII, p. 346 (1869). 



The present genus contains the largest of our American locusts, 

 with perhaps a single exception. They occur from southern Texas 

 to middle Argentina and Paraguay. At least six distinct species 

 have been recognized, but many more described. The synonymy of 

 the different species is quite complicated, and possibly never will be 

 entirely deciphered. The different forms are separated by Pictet and 

 Saussure in their Catalogue d'Acridiens, pp. 28-29. Practically all 

 of the recognized forms, save possibly one. are to be found in Brazilian 

 territory. 



95. Tropidacris collaris (Stoll).

 Grosso, Brazil, is referred here with some doubt. (Collected by H. H. 

 Smith in January.)
