Bruner: Tropical American Tettigonoidea. 369 



lobes nearly straight. Tegmina present but abbreviated, the stridii- 

 lating veins well developed. Legs long, the anterior femora robust, 

 fully twice the length of the i)ronotum, broadly sulcate beneath and 

 spined as well as finely serrated on both margins; anterior tibia 

 slenderer, and more elongate, somewhat bowed (the auditory openings 

 on both sides linear), both edges provided with six long, strong, 

 articulated spines, the apical pair much the shortest. Intermediate 

 femora shorter and less robust, the under side also sulcate and both 

 serrate and spined, the spines, however, being smaller. Hind femora 

 long, robust on basal half, slender beyond, the genicular lobes minutely 

 and bluntly spined, lower margins both spined with two series as are 

 the anterior and middle pairs; hind tibiae numerously spined both 

 above and below, the spines of ordinary size, the apex above with a 

 robust spine on each side, below with two on each side. Anterior 

 coxae above lengthily spined, intermediate and hind pairs below bluntly 

 spined. Pro-, meso- and meta-sternum provided with two erect, 

 rather long spines. Cerci robust, the apical half bent abruptly 

 inwards and tapering to an acute point; subgenital plate provided 

 with rather long finger-like styles.

For the size of this insect giving the general impression of being 

 moderately graceful. General color brunneo-testaceous, the front 

 transversely finely aciculate, and more nearly castaneous in color; 

 mandibles black on apical half. Lower side of the anterior femora 

 jet-black, the surface also finel}' transversely aciculate. Anterior and 

 middle tibiae castaneous at base of spines. Tegmina infuscated, the 

 veins and veinlets brunneo-testaceous. 



Length of body, cf , 38 mm., of pronotum, 10 mm., greatest width, 

 9 mm., length of tegmina, 10 mm., length of anterior femora, 20 mm., 

 of anterior tibiae, 24 mm., of middle femora, 16 mm., of middle tibiae, 

 17 mm., of hind femora, 29 mm.; of hind tibiae, 31 mm. 



Habitat. — The type, a male and only specimen examined, comes from 

 Chapada, Brazil, where it was taken presumably by H. H. Smith in 

 September. It is in the Carnegie IVIuseum. 



There is a female specimen at hand from the same general locality, 

 but it seems to be somewhat immature. The ovipositor is rather 

 long and slender as in the Gryllacrida. The anterior legs are less 

 robust and comparatively shorter than in the opposite sex described 

 above somewhat in detail. This female specimen was taken in May.
