and robust, fully as broad as the anterior part of the pronotum, the 

 fastigium gently ascending, sub-globose, nearly as wide as long, 

 toothed below and rather widely separated from the fastigium of the 

 front, its anterior margin evenly rounded. Pronotum a little longer 

 than wide, its surface somewhat rugoso-punctate, most decidedly so 

 on the disc, the lateral lobes furnished with a large depressed more or 

 less transparent and sub-glabrous area, anterior margin above broadly 

 emarginate, the hind margin subtruncate, the lateral lobes hea\ily 

 margined. Elytra broad, fully twice as long as the abdomen and one- 

 half again as long as the hind femora, their apex subacuminate, the 

 costal vein not prominent, strongly divergent from the radial. An- 

 terior femora provided with three spines, the intermediate with four 

 spines and the hind pair with numerous black tipped spines arising in 

 advance of rather large black blotches. Ovipositor broad, long, gently 

 decurved, the apex obliquely acuminate from below. Subgenital 

 plate carinated at middle, tapering, roundly emarginate at its apex. 



General color bright grass-green, the basal half of the hind femora, 

 ovipositor, and occiput, together with the upper part of the front, and 

 cheeks and antennae ferrugineo-testaceous. Mandibles bright saff- 

 ron-yellow, the labrum, labium, and apical joints of the palpi purplish. 

 Femora below prominently punctate or maculate with deep black, the 

 tarsi, tips of the femora and tips as well as base of the tibice infuscate. 

 Anterior margin of the fastigium of the vertex yellow-banded, scarcely 

 fuscous-bordered beneath. Apex of the ovipositor somewhat infus- 

 cated. Eyes walnut-brown. Tegmina provided centrally on the ajn- 

 cal two-fifths with fuscous maculations, the anterior margin pellucid. 



Length of body 43 mm.; of fastigium 2.25 mm.; of pronotum 9.5 

 mm.; of tegmina 65 mm.; of hind femora, 38 mm.; of ovipositor, 

 42 mm. 



Habitat. — The type and only specimen at hand was taken by J. 

 Steinbach in the "Province del Sara," Bolivia, at an elevation of 350 

 meters above sea-level. It bears the Accession Number 5058.
