1/ . 8 mm. Piceous or very dart l'eddish- brown ; femora and 

 tibiae a little paler or more reddish, tarsi and antennae ferruginous. 

 Pubescence almost obsolete on the body, yellowish, coarse, oblique and 

 fairly long on the legs and antennae. Pilosity short and yellowish, 

 very scanty, especially on the thorax ; some of the hairs on the head 

 and abdomen are closely adpressed, the rest oblique. Anterior half of 

 the head with a slight gloss, the clypeus and space between the frontal 

 carinae smooth and more shining, closely reticulate-punctate and 

 longitudinally rugoso-striate, the striae fairly wide apart. Posterior 

 half of the head very smooth and shining, with a few large punctures. 

 Thorax, upper faces of the nodes and the extreme base of the abdomen 

 superficially and finely reticulate, and with a few feeble transverse 

 rugae here and there ; abdomen smooth and shining. Head, excluding 

 the mandibles, as long as wide, widest in the middle, distinctly 

 narrowed in front, not much so behind, the sides convex, the posterior 

 margin not deeply excised, the apex of the excision and the occipital 

 lobes rounded. Occipito-frontal sulcus shallow. The head is highest 

 in the middle, and has a very shallow depression on each side above 

 and behind the eyes. Clypeus feebly carinate, widely and fairly 

 deeply emarginate in front. Mandibles smooth, shining, very finely 

 and sparsely punctured ; a row of larger punctures borders the masti- 

 catory margin. Scapes extend a little beyond the middle of the head. 

 Eyes small, placed at the anterior third of the sides. Posterior lateral 

 angles of the pronotum moderately acute and prominent. Pro- 

 mesonotal suture distinctly defined. Mesonotum with a transverse 

 median impression, and a transverse torus above the scutellum. 

 Dorsum of epinotum horizontal and flat, one and three-quarter times 

 longer than wide, as long as the declivity ; epinotal spines acute, sub- 

 vertical, divergent, very little longer than their basal width. Posterior 

 dorsal face of the 1st node as wide as long, the dorsal edge barely 

 emarginate ; 2nd node two and a-third times wider than long, the 

 anterior margin semicircular, the sides moderately angular, but not 

 spinose or dentiform. Abdomen subcircular, the base transverse.
