£ . 11 mm. Black ; mandibles and last four joints of all the 

 tarsi, apical half of last joint of nagellum, and extreme base of the 

 scape, castaneous brown. Calcaria dirty yellow. Extreme apex of 

 abdomen ferruginous. 



Whole body covered with a short and inconspicuous golden-grey 

 pubescence, punctured all over with very fine, close, and shallow 

 punctures ; these punctures are coarser and confluent on the head, 

 thorax and node of petiole. Intermixed with these are some larger 

 shallow piligerous punctures, which are most abundant on the 

 epinotum, node of petiole and first two abdominal segments. The 

 hairs are short, erect, and black, but on the apical abdominal segment 

 longer and golden brown. 



Clypeus raised in the centre and somewhat projecting, ending 

 anteriorly in a blunt point, emarginate laterally and fringed with a 

 few golden bristles on the anterior margin. It is produced behind 

 angularly between the frontal carinae. The latter are broad in 

 front, arcuate at the sides and divergent behind, and extend back- 

 wards to a point level with the posterior margin of the eyes. The 

 latter are not large, and are placed at the middle of the sides of the 

 head. Mandibles triangular, very finely striate and with a row of 

 coarse punctures on the masticatory margin, which is furnished 

 with about 8 or 9 teeth. 



Antennae reach back hardly as far as the node of the petiole. 

 Scape flattened and incrassate apically, not longer than the head 

 excluding the mandibles. Flagellum very slightly clavate, apical 

 joint longest, the rest sub-equal. 



Pronotum large, rounded in front. Pro-mesonotal suture distinct. 

 Epinotum rounded above, the declivity gradual and with the lateral 

 margins well defined. Node of petiole, seen from above, trapezoid, 

 wider behind than in front ; seen from the side, sharply truncate in 

 front and behind, rounded above. Ventral lamella not produced.
