Bruner: Saltatorial Orthoptera. 31 



Only a single male specimen coming from the Province del Saral 

 Bolivia is referred here. It was collected by Steinbach at an elevation 

 of 450 meters above sea-level. It is quite typical, and agrees well, 

 with the large series examined by me and reported upon in a previous 

 paper appearing in the Annals, Vol. VIII, p. 34. 



Genus Staurorhectus Giglio-Tos. 



Staurorhectus Giglio-Tos, Boll. Mus. Zool. Anat. Comp., XII, no. 302, p. 25 

 (1897); Bruner, Ann. Carnegie Mus., VIII, p. 31 (1911). 



54. Staurorhectus longicornis Giglio-Tos. 



Staurorhectus longicornis Giglio-Tos, I. c, p. 26 (1997); Bruner, I. c, p. 31 



(1911). 



The collection contains three specimens of this locust, two males 

 from the Province del Sara, Bolivia, and a female, the latter from the 

 Rio Bermejo, Province of Salta, Argentina. They were taken in 

 February, March, and April by J. Steinbach. 



While the males of this species are quite uniform as to color, the 

 females are apt to vary greatly in this respect. 



Genus Compsacris Bolivar. 



Compsacris Bolivar, Anal. Soc. Espan. Hist. Nat., XIX, p. 315 (1890); Rehn, 

 Trans. Amer. Ent. Soc, XLII, p. 279 (1906); Bruner, Ann. Carnegie Mus., 

 VIII, p. 445 (1913)- 

 This genus comes near to Staurorhectus Giglio-Tos, but is distinct. 



It belongs to the region of the upper Amazons in eastern Bolivia and 



southwestern Brazil. 



55. Compsacris pulcher Bolivar. 



Compsacris pulcher Bolivar, I. c, p. 315 (1890); Rehn, Trans. Amer. Ent. Soc, 



XLII, p. 279 (1916). 

 Staurorhectus intermedius Bruner, Ann. Carnegie Mus., VIII, p. 31 (191 1). 



The present collection contains two males and a female of this 

 species. They come from Benevides, Para, Brazil, where they were 

 taken by S. M. Klages in October, 1918. C. M. Ace. No. 6174. 



The males and females of this insect agree with the female of my 

 Amblyscapheiis lineaiiis from Paraguay in having the apical joints of 

 the antennae white or pallid; but the valves of the ovipositor are 

 very unlike those of A. lineatus.
