NO. 1661. ON SOME BRAZILIAN GRASSHOPPERS— REIIN. 



157 



Measurements. 



A parat^'pic series of one male and two females taken in June and 

 November have also been examined. In color there is a fair amount 

 of variation, one male and one female being quite reddish, while the 

 other female is Vandyke brown in general tone, livened on the sides 



with olive. 



Genus XIPHIOLA Bolivar. 



XIPHIOLA BORELLII Giglio-Tos. 



Chapada, Matto Grosso, Brazil. April, June, and August. (II. H. 

 Smith.) Three males, two females. 



This species is now known to range over the country adj acent to the 

 Paraguay River from Sapucay, Paraguay, north to Chapada. 



Genus SCHISTOCERCA Stal. 



SCHISTOCERCA DESILIENS Scudder. 



1899. Schistocerca desiliens Scudder, Proc. Amer. Acad. Arts and Sci., XXXIV, 

 p. 455. [Rio de Janeiro and Victoria, Brazil.] 



Bahia, Brazil. March 21, 1883. (A. Koebele.) One male. 



Bonito, Pernambuco, Brazil. January, February, and July, 1883. 

 (A. Koebele.) Two males, five females. 



Pernambuco, Pernambuco, Brazil. January 4, 1883. (A. Koe- 

 bele.) One female. 



Several of the specimens here recorded from Bonito are labeled as 

 having been " collected on cotton." 



This species appears to connect the 'pyramidata-za'poteca type with 

 the Jiavofasciata-injmnata series, though it seems quite probable that 

 desiliens is nothing but a geographic race or form of Jiavo-fasciata. 

 Bruner has observed this species at Asuncion, Paraguay. 



SCHISTOCERCA FLAVOFASCIATA (De Geer). 



1773. Acrydium flavo-fasciatum De Geer, Mem. Hist. Ins., Ill, p. 489, pi. xl, 

 fig. 8. [Surinam."] 



« From the locality it would seem there exists a strong possibility that this name 

 was originally based on the form to which Scudder gave the name sequalis. Nothing 

 diagnostic enough to settle the matter is contained in the original De Geerian descrip- 

 tion, and without Surinam material we would hardly be justified in stating that speci- 

 mens from that locality are identical with Demerara individuals, which were the basis 

 of sequalis, although the probability is of course very great. The statement made by 

 Scudder (Proc. Acad. Arts and Sci., XXXIV, p. 456) that the species was originally 

 described from Brazil was probably due to St^l's use of Brazil as the habitat of the 

 species (Recensio Orthopterofum, I, p. 67). De Geer, however, distinctly gives 

 Surinam as the source.
