 fourteen-spined internally. Prosternal spine mod irately robust, a 

 little compressed laterally, broadly rounded apically and gently 

 directed to the rear.

 pleura, and tegmina (possibly pale grass-green in life). Sides of head 

 belov the eyes, lower edges of pronotum, and lower portion of pleura, 

 marked bj a rather wide pallid band bordered above by a faint trace

 black internally and below. Wings strongly infuscated. 



Length of body, 9 , 44 mm., of pronotum, 6.75 mm., of tegmina, 40

Habitat. — -A single female, the type, was taken at Chapada, near 

 Cuyaba, Matto Grosso, Brazil, in June by H. H. Smith. It is de- 

 posited in the Carnegie Museum. 



On account of the robust structure of the head and thorax of this 

 insect it has a strongly wedge-shaped form when viewed laterally, the 

 abdomen being evenly slenderer from the base to its apex.

Genus Oxybleptella Giglio-Tos. 



Oxybleptella Giglio-Tos, Boll, Mus. Zool. Anat. Torino, IX, no. 184, p. 33 (1894). 



Two representatives of this genus are known. They both belong 



to the region now under consideration. 



1 is. Oxybleptella sagitta Giglio-Tos. 



Oxyhlcplclla sagitta Giglio-Tos, Boll. Mas. Zool. Anat. Torino, IX, no. 184, p. 33, 

 pi. 1, fig. 7 (1894). 



Habitat. — Specimens, taken at Chapada Brazil, during the months 

 of May, June, and July by II. II. Smith, are referred to this sp< :< ies. 



James A. G. Rehn described a second species of the genus from this 

 same locality (Proc. U. S. Nat. Mas.. XXXVI, pp. 1 36 [39, tigs. 21, 

 22, 23, 1909). It has not been definitely recognized among the 

 material before me now.
