The short clypeus is arcuately emarginate in the middle of the anterior 

 margin, but is not crenelate. The frontal carinae are as in Mocquerysi, 

 closely approximated, separated only by the frontal sulcus which 

 reaches back to the neighbourhood of the ocelli, and are divergent 

 behind, and longer than in Mocquerysi. The scape does not extend 

 back as far as the anterior third of the eye ; the 2nd joint of the 

 flagellum is as long as wide, the rest, excepting the last joint, wider 

 than long. Only two ocelli present. The rather large eyes are 

 situated behind the middle of the sides, and occupy about half the 

 length of the same. The head is but slightly emarginate behind. 

 The thorax is not much narrower behind than it is between the 

 anterior angles of the pronotum ; the latter is reversed trapeze- shaped, 

 feebly convex above, a little shorter than wide, the side margins with 

 a sharp, narrow, raised border, the anterior angles rounded and 

 prominent. The mesonotum is short, semi-circular, twice as wide as 

 long. The metanotum is separated from the mesonotum by a narrow 

 sulcus, very short and almost linear in the middle, longer at the sides ; 

 the metanotum is not distinctly defined from the epinotum. The 

 epinotum is sharply marginate laterally, the dorsum flat, the brow of 

 the declivity rounded. The 1st joint of the petiole is triangular, the 

 sides sharply margined, hardly pedunculate, widening posteriorly, 

 seen from above flat transversely, but very convex in profile. The 2nd 

 joint is much wider, but shorter than the 1st, nearly twice as wide as 

 long. The abdomen is elongate- ovate. The legs are fairly short."

" £. 3 - ]-4'7 mm. Black, mandibles, articulations of the legs, 

 tarsi, and often also the tibiae brownish yellowish-red, the antennae 

 usually reddish yellow with brownish club. Pilosity almost absent, 

 the adpressed pubescence very sparse. The whole body shining, finely 

 rugulose and with some scanty punctures, bearing fine hairs; the 

 front of the head, and to a certain extent the cheeks, longitudinally 

 striate, the mandibles coarsely rugoso-striate. The mandibles, particu- 

 larly in the larger specimens, depressed and flattened in the apical 

 half, the teeth obtuse. Head wider than the thorax, distinctly longer 

 than wide. The middle portion of the clypeus in the larger $ $ more 

 or less angularly produced (strongly so in the ?). The scape does 

 not reach back to the posterior margin of the eyes ; the 2nd-6th
