Bruner: Saltatorial Orthoptera. 49 



plete description of the species now. Two of them come from the 

 Upper Mamore River in the Department of Santa Cruz, Bolivia, 

 where they were taken in December, 191 3, at an altitude of 200 meters 

 above sea-level. The other specimen was collected in November, 

 at Quatro-Ojos in the same pro\ince at an elevation of 300 meters. 

 All three of them were obtained by Haseman. The last mentioned 

 specimen belongs to C. M. Ace. No. 5059, and the former two to C. M. 

 Ace. No. 5061. 



All three specimens show a decided rufous tinge on the dorsum of 

 the pronotum, as did the type-material, as now recalled by me. 



93. Stenacris forficulata sp. no v. 



Two males belonging to this genus and coming from Ouatro-Ojos, 

 in the Department of Santa Cruz, Bolivia, are separated from the 

 preceding by the structure or the male genitalia. They belong in 

 the section of the genus containing S. columbcr and S. fissicaiida 

 Bruner, as characterized in the Biologia Centrali-Americana, Orth., 

 II, pp. 225 and 258. When compared with these two species forficulata 

 approaches fissicaiida most closely in size and in the structure of the 

 apica] segment of the male abdomen. The general color of the insect 

 is pale grass-green, with little or no indication of a longitudinal pallid 

 lateral line on the sides on the head, pronotum, and thorax, as is so 

 frequently seen in several of the species of the genus. The wings, 

 although not spread, appear to be infuscated and to have a slightly 

 bluish tinge. The dorsum of the abdomen, however, is a little in- 

 fuscated, and the hind tarsi are tinged with pinkish red. 



Length of body, cf, 26 mm.; of pronotum, 5.5 mm.; of tegmina, 

 22 mm.; of hind femora, 13 mm. The female which is also assigned 

 to this species is 30 mm. in length, with the tegmina 27 mm. long. 



Habitat: Quatro-Ojos, Department of Santa Cruz, Bolivia, at an 

 altitude of 300 meters above sea-level. Taken in November, 1913, by 

 J. Steinbach. C. M. Ace. No. 5059. 



94. Stenacris sp.(?) 



There are at hand two females of what appears to be still another 

 species of Stenacris. They were taken on Uassa Island in the Uassa 

 Swamp during the month of June, 1918, by S. M. Klages. C. M. 

 Ace. No. 6176.
