acutely bidentate ; the petiole more robust, the 2nd node transversely 

 ovate.

<£> . 2*2 mm. Reddish-brown, the petiole a little paler, the abdo- 

 men dark brown, legs, antennae, and mandibles brownish-yellow. 

 Head, thorax, and nodes very slightly shining, abdomen smooth and 

 very shining. Pilosity scanty, composed of whitish and rather blunt- 

 hairs, oblique on the abdomen, erect elsewhere. Legs and antennae 

 pubescent only, the pubescence very short and sparse. 



Head longitudinally striate between the frontal carinae, reticulate 

 at the sides, the reticulations becoming finer and smaller towards the 

 posterior angles and the frontal carinae. Thorax, epinotum, and 

 nodes finely reticulate-punctate. On the pro-mesonotum a coarser 

 reticulation is superimposed, almost rugose ; the sculpture of the 

 nodes is very feeble. Sides of pronotum closely reticulate-punctate, 

 the sides of the mesonotum more strongly so, with the meshes wider 

 than elsewhere. The peduncle of the petiole very finely reticulate or 

 alutaceous. Head quadrate, hardly longer than wide, the sides feebly 

 convex, the posterior angles narrowly rounded, the posterior margin 

 straight. Eyes placed a little in front of the middle of the sides, 

 moderately large. Frontal carinae very divergent, prolonged back as 

 thin lines to the posterior fourth of the head, no trace of scrobea. 

 Clypeus tricarinate, the median carina the strongest. Mandibles 

 6-dentate, sparsely punctured, very finely striate. Scapes not reaching 

 the hind margin of the head, 1st joint of flagellum nearly as long as 

 the four following joints taken together, 2nd- 7th joints wider than 

 long. Thoracic sutures absent, but the meso- and epinotum are ' 

 separated by a shallow depression. Dorsum of thorax feebly margi- 

 nate at the sides, half as long again as wide in front, very slightly 

 constricted between the meso- and epinotum ; shoulders of pronotum 

 subangular. Dorsum of epinotum horizontal on its basal half, the 

 apical half oblique, sloping towards the declivity, and twice as long as 

 the latter. Epinotal teeth small (but longer than the episternal), as 

 long as their basal width, directed slightly upwards, moderately 

 divergent. Declivity vertical, marginate at the sides, the episternal 

 teeth obtuse. Peduncle of petiole nearly as long as the node; the 

 latter has the anterior face vertical, higher than the posterior face, 

 which is convex and forms with the dorsal face a single convexity.
