dorsum, the stigmata below prominent. Petiole a little longer than 

 its scale is high, the latter convex behind, flat in front, the dorsal 

 edge emarginate and subdentate on each side of the emargination. 

 Abdomen longer than wide, acute at the apex, rather large, very 

 convex above. Legs long and slender. 



?. 5*8 mm. Black; femora and tibiae brown, mandibles, anterior 

 margin of the clypeus, antennae and tarsi bright ferruginous. A 

 metallic lusti'e is just visible in some lights, more or less bronzy on 

 the head and mesonotum, faintly greenish on the epinotum and 

 abdomen. Pilosity less abundant than in the £ , almost entirely 

 absent from the thorax ; the pubescence is very abundant all over, 

 longest on the scutellum, epinotum and abdomen, decumbent except 

 on the scutellum and epinotum, where it is oblique. Whole body 

 nitidulous, the abdomen somewhat duller than the rest, very closely 

 and regularly punctured. The punctures are piligerous, finest and 

 most abundant on the abdomen, fairly fine on the scutellum, large 

 and deep on the mesonotum and back of the head ; the epinotum is 

 obliquely striate, punctured between the striae. Mandibles shining, 

 sparsely and coarsely punctured. Head subtriangular, as long as 

 wide behind. Clypeus carinate on the anterior half of the median 

 area. Scapes very long, extending beyond the back of the head by 

 half their length. Mesonotum with a shallow transverse impression 

 a little in front of its basal margin, and a median longitudinal and 

 impunctate line extending from front to back; parapsidal sutures 

 clearly defined. The dorsum and declivity of the epinotum form a 

 single oblique plane, bearing a small tubercle on each side above ; the 

 extreme apex of the epinotum, facing the petiole, is shining and 

 impunctate. Petiole longer than wide, convex from side to side 

 above. Abdomen elongate, twice as long as wide. Wings tinged 

 with brown, the nervures and stigma dark brown. 



d . 2 - 8 mm. Dark brown, the thorax paler than the head and 

 abdomen and with yellowish-brown sides, antennae, legs and man- 

 dibles pale ochreous. Very shining. Pilosity and pubescence sparse, 

 the former much shorter than in the ^ or $ . Exceedingly finely and 

 sparsely punctured. Abdomen impunctate. Head subcircular, a 

 little wider than long, nearly as wide as the thorax. The eyes occupy 

 the anterior two-thirds of the sides ; the distance between the posterior 

 ocelli is twice as great as the distance between them and the anterior 

 ocellus. The scape is two-thirds as long as the flagellum, and extends 

 by a good deal more than half its length beyond the back of the head. 

 Epinotum with a small tubercle on each side above, as in the $ . 

 Scale of petiole thick, almost half as thick as wide across the top, the
