5 • 2 - 2-2*4 mm. Piceous, legs, antennae and mandibles brownish- 

 yellow. Shining, the pronotum, sides of mesonotum and mesopleurae 

 less shining than the rest of the body. Pubescence very scanty on the 

 thorax, and fairly so elsewhere, composed of thin, decumbent and 

 yellowish hairs. Erect pilosity yellowish, absent from the head except 

 on the clypeus, very sparse on the thorax and petiole, a little more 

 abundant on the abdomen, whei'e they are slightly clavate and truncate. 

 Head smooth, finely and very sparsely punctured, microscopically 

 aciculate at the sides in front of the eyes. Pronotum and sides of the 

 mesonotum sharply and finely striate longitudinally, the striae very 

 regular, the middle of the mesonotum smooth. Dorsum of epinotum

with a few short striae on each side and a fairly discrete reticulate 

 patch in the middle, the declivity almost smooth, at the most only very 

 superficially reticulate. Nodes and abdomen smooth and shining, the 

 dorsal surface of the 1st node slightly duller and very superficially 

 coriaceous. Head as wide as long, narrowed a little in front, the sides 

 moderately convex, the posterior margin shallowly concave. Eyes 

 small, flat, placed just behind the middle of the sides. The scapes do 

 not extend beyond the posterior sixth of the head ; 2nd-7th 

 joints of the flagellum at least twice as wide as long, club 2- jointed 

 or indistinctly 3- jointed. Mandibles smooth, shining, 4-dentate. 

 Clypeus transversely impressed behind the anterior margin of the 

 median area. Pro-mesonotum, seen from above, reversed pyriform, 

 the apex (i. e. meso-epinotal suture) broadly truncate. Pro-mesonotal 

 suture obsolete, meso-epinotal fairly deep and narrow. Declivity of 

 the mesonotum marginate at the sides and merging into the anterior 

 plane by a low curve. Dorsum of epinotum submarginate at the sides, 

 very short, much wider than long, delimited from the declivity only by 

 the difference of the sculpture. Epinotal teeth triangular, short, erect,
