 £. 5 - 2-6 mm., excluding the mandibles. Head, antennae, man- 

 dibles, thorax, petiole and legs a rich dark red ; 1st abdominal 

 segment castaneous red, the rest piceous or black. Whole body, 

 antennae and legs covered with a fine and rather long pubescence, 

 evenly distributed but not dense, a few long hairs on the apex of 

 abdomen. Head and thorax finely striate. On the head the striae 

 radiate from the frontal carinae diagonally to the sides. The striae 

 on the pronotum are longitudinal, on the mesonotum and epinotum 

 transverse ; the striae on the latter are less regular. The 1st 

 abdominal segment is very shallowly and evenly punctured, the 

 interspaces microscopically rugulose. The 2nd segment with very 

 shallow punctures. Second-5th abdominal segments slightly shining, 

 the rest of the body dull. Head deeply emarginate posteriorly, the 

 portion in front of the eyes about three- quarters as long as the 

 region behind. Posterior angles of the head very round. Between 

 the posterior angles and the eyes, the sides of the head are slightly 

 concave, very convex round the eyes, and moderately so between the 

 eyes and the base of the mandibles. The sides of the head are 

 hollowed out between the posterior angles and the eyes; the antennal 

 hollows are rather wide, smooth and shining. Clypeus produced 

 triangularly backwards between the frontal carinae, and raised into 

 a little hump above the base of each mandible. The sides of the 

 head between the eyes and the mandibles smooth, shining, slightly 

 and obliquely excavated. Mandibles two-thirds as long as the head, 

 widening towards the apex ; the latter is incurved at right angles to 

 the basal portion and bifid, forming two sharp teeth, the lower one 

 with a smaller tooth at its base. The inner margin of the mandible 

 is very finely denticulate, a deep notch separating it from the 

 incurved apical portion. Eyes rather large, margined all round by 

 a shining, narrow groove. Scape of antenna reaches back to the 

 occiput, flagellum filiform, slightly incrassate towards the apex, all 

 the joints longer than wide. Pronotum much narrower than the 

 head, a little wider than long, rounded at the sides and above. Pro- 

 mesonotal suture distinct, meso-epinotal nearly obsolete above. 

 Epinotum shorter than the pro- and mesonotum together. Dorsum 

 of epinotum wider at the apex than at the base ; the declivity is
