hairs are directed obliquely towards the middle longitudinal line of 

 the segments, those on the inner basal half being almost transverse 

 in direction. On the narrow middle longitudinal line the hairs are 

 parallel to the line, so that in some positions it appears almost glabrous. 

 Pilosity long, yellowish white, sparse on the head and thorax, 

 moderately abundant on the abdomen. Anterior margin of the 

 clypeus with yellow, porrect hairs. Head subtriangular, excluding 

 the mandibles barely longer than wide, the sides fairly strongly 

 convex, the posterior margin feebly so, gradually narrowed anteriorly. 

 Mandibles moderately shining, very finely striolate and punctured, 

 with 6 or 7 teeth. Clypeus strongly carinate, its lobe short and with 

 a straight anterior margin. Frontal area triangular, indistinct behind. 

 Scapes not flattened, extending just beyond the hind margin of the 

 head. Eyes feebly convex, placed just behind the middle of the sides. 

 Thorax fairly convex lengthwise, L. = 3 H. 



Metanotum indistinctly defined. Dorsum of epinotum oblique, 

 narrow above but not cristate, a little longer than the subvertical 

 declivity, their junction rounded. Scale higher than the petiole is 

 long, the anterior face moderately convex, the posterior almost flat, 

 the dorsal edge obtuse, somewhat flattened in the middle. Tibiae 

 strongly compressed, not setose below. 



y media, 7 mm. Scape reddish brown, mandibles bright brownish 

 Ted. Pubescence on the head longer and more abundant, on the 

 abdomen less abundant than in the 2L Head oblongo-ovate, two- 

 fifths longer than wide, slightly narrowed in front, the sides feebly 

 convex in front of the eyes, more convex behind them, the posterior 

 margin also convex. The scapes extend beyond the hind margin 

 by two-fifths of their length. Lobe of clypeus shorter and wider than 

 in the 21, arcuate in front. The declivity of the epinotum more 

 oblique. Scale of petiole a little thicker. Otherwise like the 2L 



^ minor, 5-5-6-5 mm. Like the £ media, but with the head narrower, 

 half as long again as wide, widest across the eyes or posterior third, 

 the sides in front of the eyes straight and more convergent anteriorly. 

 Dorsum of pronotum distinctly flattened lengthwise. Scale pro- 

 portionally narrower and thicker. 



$, 13-3 mm. Colour, sculpture, pilosity etc. as in the 2J., but the 

 pubescence of the abdomen is of a darker golden colour. Mesonotum 

 and scutellum very finely reticulate-punctate, the convex anterior 

 portion of the mesonotum, the scutellum and the metanotum slightly 

 shining ; the scutellum has a few large and shallow punctures. Head 

 like that of the $ media but trapezoidal, as long as wide behind, the
