being much less abrupt. It is also much narrower than in the 1/, 

 half as long again as wide, the posterior lateral angles represented 

 only by slight tubercles. Pro-mesonotal suture very indistinct above, 

 the meso-epinotal very deep and wide. Dorsum of the epinotum 

 feebly convex transversely and longitudinally, longer than wide, the 

 epinotal teeth similar to those of the 1/ , but smaller. The 1st node 

 of the petiole like that of the 1/ , but the dorsal edge rounded, the 

 anterior face oblique. The second node is a little longer than wide, 

 the sides convex ; seen from above, it is subconical over its anterior 

 two-thirds. Abdomen oblong-oval, the 1st segment as long as wide 

 and longer than the remaining segments taken together. 



$ . 7 mm. Dark reddish-brown or castaneous, the head usually 

 paler or more reddish. Legs and antennae yellowish-red. Mandibles, 

 clypeus and pro-mesonotum shining, head, epinotum and petiole 

 rather dull, abdomen shining but less so than the thorax. Pubescence 

 short, very sparse and inconspicuous ; pilosity sparse, not long, 

 yellowish, on the apical segments of the abdomen somewhat longer. 

 Head longitudinally striate, the cheeks and temples (i. e. the region 

 between the eyes and the frontal carinae) with some transverse striae 

 which anastomose with the longitudinal ones, the spaces between the 

 striae very finely rugulose. Mandibles triangular, stout, sparsely and 

 coarsely punctured, the masticatory margin blackish, with two apical 

 teeth and one or two obtuse teeth at its base, the space between 

 denticulate. Pro-mesonotum smooth and shining, very sparsely and 

 shallowly punctured, the mesonotum also very finely striate longi- 

 tudinally, the striae converging posteriorly. Scutellum smooth and 

 shining above, reticulate- striate at the sides, separated from the 

 mesonotum by a deep and clathrate groove. Epinotum, nodes of 

 petiole above and the abdomen more or less reticulate, the abdomen 

 exceedingly finely so. Legs shining and sparsely punctured. 



Head widest behind, one fifth wider than long, the sides convex, the 

 posterior margin straight. Eyes very convex, placed a little in front 

 of the middle of the sides. Anterior margin of the clypeus shallowly 

 emarginate in the middle. Frontal area distinct, subtriangular. 

 Frontal carinae slightly divergent behind. The scape extends back as 

 far as the posterior margin of the head. Pronotum not exposed above 

 except the narrow neck portion. Mesonotum a little more than one- 

 quarter wider than long, convex in front, flattened behind, its anterior 

 margin, seen from above, semicircular. Metanotum very short. 

 Epinotum transversely concave between the teeth, sometimes rather 

 deeply so ; the dorsum very steep, short, narrowed posteriorly, the 

 declivity subvertical. Epinotal teeth short, acute, not longer than
