than the anterior margin. Eyes placed behind the middle of the 

 sides, between the third and last fourth. Frontal carinae less sinuate 

 than in the Qj, hardly wider apart behind than in front. Clypeus 

 more distinctly carinate, and with a longer lobe in front than in 

 the Oj, its angles also sharper. The scapes extend beyond the hind 

 margin by nearly half their length. Convexity of thorax slightly 

 greater than in the Qj, the pronotum sloping much more steeply 

 downwards in front, and flatter above. The dorsum of the epinotum 

 is one and three-quarter times longer than the declivity. Scale of 

 petiole thicker but hardly more convex in front. Otherwise like the Qj.. 



9, 12 mm. Head trapezoidal, widest behind, the posterior angles 

 moderately rounded, a trifle longer than wide. Clypeus barely cari- 

 nate. The anterior third of the head with a sparse and shallow 

 puncturation in addition to the fundamental sculpture. Mesonotum, 

 scutellum , and abdomen slightly shining. The mesonotum very 

 finely rugulose. with a few large pit-like punctures at the base and 

 on the sides. Scutellum almost as wide behind as in front. Dorsum 

 of epinotum very short, merging rapidly into the vertical declivity. 

 Scale of petiole much wider than in the Qj., the dorsal edge trenchant 

 and emarginate in the middle. Abdomen very shallowly punctured 

 as well as rugulose. Femora dark brown. Dealated. Otherwise 

 like the Qj. 



(?, 6'3 mm. Dark blackish brown, mandibles, the basal two-thirds 

 of the scapes, the tarsi and the bases of the tibiae ochreous, the 

 flagellum brownish yellow. Head, mesonotum and scutellum dull, 

 the rest slightly shining. Pilosity and pubescence thinner and scan- 

 tier than in the Q. The outline of the head, seen fron above, is 

 semicircular behind the eyes, in front of them the sides are straight 

 and moderately convergent anteriorly. Head as long as wide across 

 the eyes. The latter placed in the middle, large, convex and pro- 

 minent. The scapes are as long as the head (including open man- 

 dibles). Mandibles strongly pubescent, slightly shining and sparsely 

 punctured. Clypeus with a median transverse impression a little 

 behind the straight anterior margin ; behind the impression the 

 median area is gibbous or almost tuberculate, hardly carinate. On 

 the very convex anterior half of the mesonotum there is a shining 

 longitudinal line on each side of the median line, which merge 

 together at about the middle of the mesonotum. Scale of petiole 

 thick, moderately convex in front and behind, twice as wide as high 

 and at least three times wider than thick, subquadrate when seen
