Tettigidea australis sp. nov. 



A small species with attenuate pronotum in which the dorsum of this 

 portion is coarsely granulate and shows definite traces of longitudinal 

 supplemental carinae both in front and between the humeri, formed chiefly 

 by the alignment of some of the granulations. 



Head nearly normal, or possibly a trifle high, the front somewhat 

 oblique; eyes large, a little prominent; the top of the head only mod- 

 erately deeply sulcate and furnished with blunt longitudinal rugae, the 

 vertex slightly advanced in front of the eyes, the lateral carinae strong and 

 gently arcuate, almost touching the upper carina of frontal costa; the 

 latter not prominent, profoundly sulcate and continued above nearly to 

 a point opposite the middle of the eyes; antennae located just within a 

 line drawn between the lower edges of the eyes. Pronotum moderately 

 slender, its anterior edge angulate and spined at middle, the posterior 

 portion reaching the tips of the hind femora. Tegmina small, the disk 

 sparsely granulose, the granules arranged into irregular rows. Hind 

 thighs somewhat robust, the carinae strong but the general surface not 

 especially rough. 



General color brownish testaceous above, at the sides varied with piceous 

 and fuscous; face, cheeks, lower lateral edges of the pronotum, and under- 

 side dull testaceous; tegmina immaculate, fuscous; hind femora and sides 

 of abdomen fuscous somewhat mottled and varied with testaceous,' anterior 

 and middle legs very faintly annulate. 



Length of body, d^, 7 mm.; of pronotum, 8 mm.; of hind femora, 4.6 

 mm. ; total length to tip of wings, 9.85 mm. 



Habitat. — Chapada^ near Cuyaba, Matto Grosso, Brazil, a single male, 

 collected by H. H. Smith during the month of April. Carnegie Museum, 

 Pittsburgh. 



Only for the presence of the spine on the anterior edge of the pronotum 

 this insect would remind one strongly of a diminutive T. lateralis and a 

 couple of its North American allies. 



Tettigidea intermedia sp. nov. 



Slightly below the medium in size and somewhat closely related to 

 chapadensis, from which it differs most markedly in the glossy and more 

 robust form, the more nearly equal size of the sexes, and the different 

 structure of the summit of the head, the vertex and frontal costa. 



Head normal, the summit depressed a little below the eyes, the sulcus 

 and longitudinal rugae inconspicuous, the latter granulose; the vertex
