convex lengthwise, widened towards the spines, which are divergent, 

 acute, and hardly longer than their basal width. First node of the 

 petiole trapezoidal, about as long as wide in front, the anterior angles 

 rounded. Second node wider than long, with a fairly well-defined 

 median longitudinal groove.

" ^ . 2 , 7-3 - 3 mm. Mandibles closely striate and sparsely punc- 

 tured. Head somewhat wider than long, the sides convex, feeblv 

 concave behind. Eyes moderately convex, placed in the middle of the 

 sides of the head. The scape extends beyond the occipital margin by a 

 trine (not as much as one-third of its width) ; 3rd-5th joints of the 

 flagellum somewhat wider than long. Frontal area and sulcus feebly 

 denned, the latter almost obsolete. Pronotum and mesonotum 

 together form a moderate and elongate convexity lengthwise and 

 transversely ; both are only indistinctly and obtusely marginate, 

 without a trace of a median carinula or prominence, the pro-mesonotal 

 suture visible. The meso-epinotal suture forms only a slight, some- 

 times very feeble constriction of the dorsum of the thorax-. The 

 dorsum of the epinotum, distinctly convex lengthwise, is not lower 

 than the mesonotum; it is somewhat wider than long and ends in 

 two short, narrow, divergent and nearly horizontal little spines, which 

 are about one-third the length of the interval between them. Declivity 

 oblique, as long as the dorsum of the epinotum. First segment of the 

 petiole not toothed below, wider than long, trapezoidal, the anterior 

 margin somewhat arcuate (or with bluntly truncated anterior angles). 

 Second node as wide as the 1st, with a complete median longitudinal 

 groove. Abdomen more oval than cordate. Head smooth ; only the 

 cheeks in front and the antennal pits rugose. Thorax finely reticulate, 

 with a few weak rugae, less shining than the head. Abdomen and 

 petiole very lightly reticulate, shining. Abdomen with a sparse 

 puncturation. Some isolated yellowish hairs on the body, none on the 

 tibiae and scapes, which have only a decumbent pubescence. The 

 latter is very sparsely distributed on the body. Dull reddish-brown 

 head and abdomen dark brown.
