 apices suhrotund. Upper carina of the anterior femora fairly prominent, 

 scarcely undulate; the lower carina more [irominent and gently lobate or 

 clypeate; the carina? of the midtUe femora very ])rominent, clypeate, 

 the lower one evenly increasing in width apically, provided with a strong

 rather large wart-like elevations: hind tibire adorned externally with ii-

Sclerotettix variegatus sp. no v. 



\'ery similar to the preceding, but differing from it in the comparatively 

 smoother pronotum and legs, and the less depressed dorsum of the pro- 

 notum, which in the present species has the lateral carinas lower and the 

 median one faint but continuous even between the nodose undulations. 

 It also differs from tibialis in lacking the lobiform superior carina on the 

 middle tibiae, while the lower posterior angles of the pronotum in variegatus 

 are less strongly turned outwards and more rounded than in the species 

 with which compared. 



Length of body, & and 9, 7.5 mm.; of pronotum, 9.5-10 mm.; of hind 

 femora, 5 mm. 



Habitat. — Chapada, Brazil, April, July, and October, collect d by H. H. 

 Smith. Carnegie Museum, Pittsburgh. 



This insect while approaching tibialis in color and general appearance 

 has the lower carina of the middle femora somewhat narrower and less 

 foliaceous and at the same time showing a tendency towards being undu- 

 late. 



Sclerotettix infuscatus sp. nov. 



Body and pronotum much smoother and with carinae lower than in the 

 three preceding forms, about the size of variegatus but having the two sexes
