REHN AND HEBARD 41 



Generic Description. — Fastigium of vertex narrow, compressed; 

 bearing three pyramidical projections, one meso-caudad, the others 

 on each side placed at a short distance cephalad of the median 

 projection; this fastigium dechvent, in partial contact with the 

 facial fastigium. Eyes sub-globose. Antennae subcrassate proxi- 

 mad. Lateral margins of dorsum of pronotum not constricted, 

 rounded; lateral lobes of pronotum perpendicular to dorsum but 

 set obliquely to it in such a way that the ventro-cephalie angle lies 

 in a position considerably cephalad of the dorso-cephalic angle. 

 Tegmina long and very broad, particularly toward the apex which 

 is obliquely truncate. Wings present. Abdomen weakly dilated, 

 dorsal segments of same not produced mesad. Disto-dorsal seg- 

 ment of male abdomen w^eakly bilobate; cerci of male exceedingly 

 long, crassate proximad, distal third incurved. Subgenital plate 

 of male with lateral margins produced distad in small, glabrous, 

 bulbous, non-articulate points. Cephalic and median femora with 

 genicular margins not produced meso-dorsad; genicular lobes of 

 same weak, bearing a single spine; ventro-cephalie margins of these 

 femora armed with five or six heavy teeth. Cephalic tibiae with 

 proximal extremity extremely swollen, narrowing very abruptly 

 below the tympanum which organ is open on both sides, dorsal 

 margins of same unarmed except for a single apical spine.

 forked, disappearing before the apex of the elytra, ulnar vein not 

 ramose. Wings acuminate. Anterior femora ? Intermediate and 

 posterior femora rounded above, the former distinctly twice an-
