Bruner: Tropical American Tettigonoidea. 323 



figured for rostrata Rchn. General color much as in chapadensis, 

 but a little paler. 



Length of body, d^, 21 mm., 9, 22 mm.; of pronotum, cf', 3.85 

 mm., 9, 4.15 mm.; of tegmina- cf, 29 mm., 9, 31 mm.; width of 

 tegmina, cf, 9, 6.5 mm.; length of hind femora, cf, 18.5 mm., 9, 

 19.5 mm., of ovipositor, 9 , 13.5 mm. 



Habitat. — The types male and female, come from Puerto Suarez, 

 Bolivia, where they were taken by J. Steinbach during the months 

 of November to January. They are in the Carnegie Museum. 



Other individuals are also at hand from the same locality. The 

 male genitalia are the same in all the specimens, as is likewise the 

 ovipositor in the various females at hand. 



Genus Tomeophora Brunner. 

 Tomeophora Brunner, Mon. Phaneropt., pp. 28, 299 (1878). 



This genus of katydids is entirely confined to South America, where 

 the known species seem to be more or less restricted in their distri- 

 bution. Judging from their peculiar tegminal venation I surmise 

 that they are either found among bamboos, or infest grass rather than 

 arboreal and herbaceous vegetation. Three species have previously 

 been described, while two are now characterized. Possibly still 

 others remain undiscovered. The subjoined table will materially 

 assist in separating the forms: 



Synopsis of the Species of Tomeophora. 

 A. Fastigium cf the vertex laminately compressed, greatly surpassing the first 



antennal joint gladialrix Brunner. 



A A. Fastigium of the vertex not greatly surpassing the first antennal joint, usually 



obtuse. 



b. Tegmina with their median width about twice the length of the prQnotum. 



c. Tegmina with their posterior margin distinctly rounded. Fastigium 



of the vertex equal to the first antennal joint in length, sulcate. 



[Peru] pungiunculata Brunner. 



cc. Tegmina with their hind margin straight. Fastigium one-half the 

 length of the first antennal joint, scarcely sulcate. [Bolivia]. 



brevirosiris sp. nov. 

 bb. Tegmina with their median width less than twice the length of the prono- 

 tum. 

 c. Posterior margin of the pronotal disc angulate, the hind margin of 

 the tegmina rounded. (Veins of the tegmina prominent, parallel). 



ovatipennis sp. ncv. 



cc. Posterior margin of pronotal disc rounded, the hind margin of tegmina 



straight. Veins of the tegmina not prominent. . .modesta Brunner.
