 A single female specimen of a small robust grouse-locust, which was 

 at first determined by me as Paratettix horellii of Giglio-Tos, seems 

 to belong in the present genus as limited and defined by Hancock. 

 Our specimen agrees fairly well with the descriptions of both lohiilatiis 

 Stal and fossulatus Bolivar. But when compared with specimens of 

 Paratettix horellii in my possession, coming from Argentina, I am 

 inclined to choose Rehn's diagnosis as more nearly correct. The 

 specimen is from the Province del Sara, Bolivia, where it was taken 

 by J. Steinbach during the period from March to April, 191 3, at a 

 locality about 350 meters above sea-level. C. M. i^cc. No. 5058. 



12. Rytinatettix affinis sp. nov. (?) 



A second specimen, a male, also apparently belonging to this genus, 

 is at hand. It comes from the Rio Bermejo in the Province of Salta, 

 Argentina, where it was taken at an elevation of 400 meters above sea- 

 level. In general appearance it is much smoother and has longer 

 wings and pronotum than the preceding insect. It may be called 

 Rytinatettix affinis. It is dull ferruginous, or inclining to wood- 

 brown, and faintly variegated with fuscous. The median carina of 

 the pronotum is less prominent and only moderately undulate. Its 

 measurements are as follows: Length of body, cf , 6.5 mm.; of pro- 

 notum, 9 mm.; of posterior femora, 5 mm.; the wings extend i mm. 

 beyond the apex of the pronotum. Collected by J. Steinbach, May, 

 1914.

13. Tettigidea glabrata sp. nov. 



A moderately large, but not excessively robust insect, having a 

 nearly uniform dark fusco-brunneous color, the entire surface of 

 which is glabrous, or, I might say, appearing to have been freshly 

 varnished. Viewed laterally, the insect has a rather fusiform wedge 

 shape, i.e., the sides and edges of the wedge are somewhat arcuate or
