up by Scudder (I. c, pp. .441-476). Since that time several additional 

 species have been added by Rehn and myself, and still another is 

 described in the present paper. 



172. Schistocerca desiliens Scudder. 



Schistocerca desiliens Scudder, Proc. Amer. Acad. Arts & Sci., XXXIV, pp. 443, 445 

 (1899). 



Habitat. — This species is represented by thirteen specimens. They 

 come from Rio de Janeiro, Para, and Chapada, Brazil, where they were 

 taken during the months of May and November by H. H. Smith. 



173. Schistocerca flavofasciata (De Geer). 



Acrydium flavofasciatum De Geer, Mem. Ins., Ill, p. 488, pi. XL, fig. 8 (1773). 

 For additional synonymy see Scudder or Kirby. 



Habitat. — This species is quite widely distributed in the tropical 

 portions of South America. Only four specimens happen to be con- 

 tained in the present collection. They come from Chapada, near 

 Cuyaba, Matto Grosso, and Para, Brazil. The former were taken in 

 April and the latter during May (H. H. Smith). 



174. Schistocerca idonea Scudder. 



Schistocerca idonea Scudder, Proc. Amer. Acad. Arts & Sci., XXXIV, pp. 444, 461 

 (1899). 



Habitat. — The collection before me contains a single male and two 

 females. They were taken at Chapada, near Cuyaba, Matto Grosso, 

 Brazil, during the months of May and August by H. H. Smith. 



These specimens are quite typical and come from the same region 

 as did Scudder's types ("Crapada" which must certainly be a mis- 

 print for "Chapada"). 



175. Schistocerca sp.? 



There are at hand five specimens, two males and three females, of 

 another species of the genus. They do not quite fit any of the de- 

 scriptions available, but appear to be related to S. americana Drury. 

 They are, however, a little smaller and lack the infuscations of the 

 costal margin of the tegmina. 



Habitat. — Para, Brazil, during May (H. H. Smith).
