pubescence, which is longer on the abdomen. Impunctate, sub- 

 nitidulous. Head somewhat triangular, much wider behind than in 

 front, sides very convex, posterior angles strongly rounded, occipital 

 margin feebly arcuate. Mandibles moderately long, triangular, the 

 basal margin two-thirds as long as the masticatory, the latter with 

 4 or 5 blunt teeth, and a large and sharp apical tooth. Clypeus 

 feebly convex, the anterior margin slightly depressed and shallowly 

 concave in the middle, posterior margin well defined. Frontal 

 carinae short, flat and divergent behind. The scape reaches back 

 beyond the occipital margin by one-fifth of its own length ; flagellum 

 slightly thickened towards the apex, all the joints longer than wide, 

 1st and 2nd joints sub-equal in length. Eyes large and flat, situated 

 somewhat dorsally in the anterior half of the head. Pronotum 

 narrower than the occipital margin of the head, moderately convex 

 at the sides and above, and as long as wide. Pro-meso and meso- 

 epinotal sutures well defined. Mesonotum longer than wide, and 

 only a little more than half as wide as the pronotum, sloping 

 towards the epinotum, from which it is separated by a wide and 

 deep depression. Dorsum of epinotum distinctly convex trans- 

 versely and longitudinally, about as long as wide, less than half 

 as long as the mesonotum. The declivity is smooth and shining. 

 The anterior face of the scale of the petiole is slightly convex, 

 the posterior face flat and shining. The scale slants forwards 

 and is widest in the middle, rounded above, and much wider 

 than thick. Abdomen oval, all the segments wider than long. 

 Legs slender. 



2 . 6 mm. Dark brown, abdomen almost black, legs, antennae 

 and mandibles paler. Pubescence longer and denser than in the £ . 

 Head, excluding the mandibles, a little longer than wide, narrower 

 in front of the eyes than behind them, sides less convex than in the 

 £ . Eyes large, occupying about one-third of the sides of the head ; 

 ocelli small, situated near the occipital margin. Pronotum almost 

 completely hidden above by the mesonotum ; the latter is very long, 

 twice as long as wide, very convex in front, moderately so at the 

 sides, and flattened posteriorly. The scutellum is about one-third 

 the length of the mesonotum, widest anteriorly, and rounded 

 posteriorly ; metanotum very short. The dorsum of the epinotum 

 is twice as long as the metanotum, much wider than long, in- 

 clined towards the declivity, which is nearly vertical, but not 

 sharply defined. Seen from the side, the thoracic profile rises 

 gradually in front towards the posterior margin of the scutellum, 

 beyond which it sinks abruptly to the level of the metanotum.
