border, and without posterior angles. Eyes a little in front of the 

 middle of the sides of the head, rather large, very convex, hemi- 

 spherical. Clypeus convex, its anterior border feebly and sinuately 

 excised in the middle. Antennse rather stout, scapes reaching a little 

 beyond the posterior border of the head, funicular joints 1 — 5 at 

 least twice as long as broad, remaining joints, except the last, less 

 than twice as long as broad. Thorax long, deeply constricted in the 

 mesoepinotal region. Pronotum flattened above and on the sides, at 

 least twice as long as broad, its raised anterior border high and

broadly rounded, its humeri scarcely angular. Mesosternum armed 

 at its base on the anterior border with a blunt tooth, which is di- 

 rected downward and forward. Mesonotum fully twice as long as 

 broad and nearly twice as broad in front as behind. Base of epi- 

 notum rising abruptly in profile in a convex curve, terminating behind 

 in a sharp border, whence the longer declivity slopes downward and 

 backward. Seen from above the base of the epinotum is slightly 

 longer than broad, very narrow in front and rapidly broadening be- 

 hind, with convex lateral and posterior borders. Petiole rather high, 

 its node placed anteriorly and inclined forward; in profile it is cuneate, 

 with feebly convex anterior and posterior surfaces and rather blunt 

 upper border. Seen from above the petiole is about ^j^ as broad as 

 the base of the epinotum. Graster large, with a slight constriction 

 between the first and second segments. Legs long and slender. 



Surface shining; mandibles coarsely punctate and finely striate, 

 at least at the base. Clypeus sharply, longitudinally rugose. Head, 

 pro- and mesonotum and base of epinotum covered with large, deep, 

 circular or slightly elliptical foveolse. These are somewhat shallower 

 on the mesonotum. Neck transversely rugose. Petiole and declivity
