" $. 5-5'5 mm. Piceous ; clypeus, antennae, legs and apical 

 segment of abdomen rufescent, dull, abdomen posteriorly and below 

 shining, very densely and finely punctulate all over, with a scanty 

 pubescence and fine pilosity ; mandibles linear, acuminate ; node of 

 petiole thick, convex above, truncate in front and behind.

" This species is remarkable chiefly by its sculpture ; the whole 

 body is finely and closely punctured, the head being entirely 

 dull; the thorax and abdomen are slightly shining, especially the 

 posterior portion and ventral surface of the latter ; the legs and 

 antennae are also punctulate and almost dull The sides and 

 posterior portion of the head are plentifully punctured, the thorax 

 with larger punctures ; the punctures become gradually smaller on 

 the petiole and abdomen, being simply piligerous points on the 

 posterior segments. The head is nearly square or slightly narrower 

 behind than in front, the eyes large, situated in front of the middle 

 of the sides of the head and separated from the base of the mandibles 

 by less than the length of their own diameter. The clypeus is widely 

 lobate, round and with a membranous margin. Mandibles narrow, 

 linear, arcuate near the base, then straight and again curved near 

 the apex, which is acute. Thorax relatively stout, the epinotum as 

 long as the pro- and mesonotum together ; the meso-epinotal 

 suture deep ; the declivity of the epinotum has the same sculpture 

 as the rest of the thorax, and the lateral margins are raised. Petiole 

 seen from the side, nearly as wide as high, sharply truncate and 

 smooth behind, convex and rugose above and in front ; seen from 

 above, hardly wider than long, and slightly narrower in front than 

 behind."
