Bruner: Tropical American Tettigonoidea. 321 



albida, though doubtfully, hear the labels "Chapada, Brazil," (H. 

 H. Smith) and " Pro\ince del Sara, 350 meters, Bolivia" (J. Stein- 

 bach). The species has been recorded heretofore from Misiones, 

 Argentina, and Sapucay, Paraguay, by Rchn, and simply "Brazil" 

 by Brunner. 



49. Grammadera chapadensis sp. no\ . 



Somewhat closely related to ulhida Brunner and rostrata Rehn, 

 but a little larger than both of them. The chief characteristics seem 

 to be in the structure of the supra-anal plate, which in this species 

 has the vertical compressed apical portion very large, smooth, and 

 formed like the blade of a broad hatchet, which when viewed laterally 

 gives the impression of a short ovipositor instead of a male appendage. 

 The male cerci are much as described for this sex of albida, as is also 

 the subgenital plate. The venation is similar to that of rostrata as 

 figured by Rehn (Proc. Acad. Nat. Sci. Philad., 1907, p. 378), while 

 the ovipositor is slightly more falcate and somewhat tapering instead 

 of noticeably broadened at the apical third. 



The general color of this insect is pale grass-green with a moderately 

 large, circular, sub-basal, dark brown maculation on the external 

 area of the stridulating field of each elytron of the male, and a narrow, 

 more or less strongly infuscated edge, on the dorsal margin in both 

 sexes. 



Length of body, cf and 9, 20 mm.; of pronotum, cf , 4.1 mm., 

 9 , 4.5 mm.; of tegmina, cf , 31 mm.; 9 , 33 mm., width of tegmina 

 cf and 9 , 7 mm.; length of hind femora, cf , 18 mm., 9 , 19-5 mm. 



Habitat. — A number of specimens are at hand from Chapada, near 

 Cuyaba, Matto-Grosso, Brazil. Types are in the Carnegie Museum. 

 There are no variations in the form of the apical portion of the supra- 

 anal plate in the ten or a dozen males examined, nor in the ovipositors 

 of the seven females at hand. 



50. Grammadera clara Brunner? 



Grammadera clara Brunner, Mon. der Phaneropt., p. 298 (1878). 



A male specimen of the genus Grammadera coming from Corumba, 

 Brazil, is referred here with some doubt. It was taken by H. H. 

 Smith. 



51. Grammadera janeirensis sp. nov. 



Related to both pellucida Giglio-Tos and forcipata, so far as the 

 structure of the male genitalia are concerned, but having the elongate
