spiracular depression. Mesoscutum with high and mostly slightly curved cross-carina in 

 anterior one-third, separating anterior sloping and more finely punctured part from the coarsely 

 punctured posterior part which is flat, sublaterally slightly depressed. Scutellum about 1-3 

 times as broad as long, mainly flat but usually more convex anteriorly and partly along median 

 line; hind margin slightly arched, without admarginal depression. Dorsellum moderately 

 convex, densely punctured, hairs not very conspicuous; hind margin rounded, not carinate. 

 Propodeum densely punctured, even laterally not unusually pubescent, medially raised, about 

 1 "j times as long as dorsellum; median carina slightly elevated in posterior third, plicae also 

 sharp. Both parts of upper mesopleurum, and metapleurum, regularly densely punctured. 

 Outer side of fore femur shiny, only sparsely punctured ; tibia with distinct dorsal and ventro- 

 lateral carinae, between them dull, densely finely punctured and pubescent. Fore and mid 

 claws pectinate, hind ones simple but with three very small teeth at base. Hind coxa elongate, 

 dorsal edge rounded, punctured, moderately narrowing caudad, posteriorly with a weak obtuse 

 outer tooth (sometimes only indicated), depression more or less smooth below and in front 

 (basad) of the tooth, sometimes smooth or with sparser punctures along the straight lateral 

 edge, but most of the slightly concave depression punctured; ventro-mesal edge smoothly 

 curved; apical auricle of coxa absent. Hind femur (Text-fig. 161) externally with smooth 

 interspaces about as broad as (or broader than) punctures; teeth of medium length, the second 

 curved and usually slightly longer than the broadly separated basal tooth, fourth to seventh 

 teeth usually fused. Hind tibia externally regularly convex, moderately sparsely punctured; 

 apical spine long, most of its adtarsal side straight, rudimentary outer spur slightly claw-like. 

 Fore wing densely finely pubescent; terminal processus of stigmal vein about half as long as 

 uncus. 



Gaster subpetiolate, rather abruptly swollen in middle, short pubescence brownish (appearing 

 pale in certain lights, dark in others) ; puncturation not very dense, rather regular, absent on 

 a broad belt along hind margin of first tergite and sparse on its flanks. First tergite elongate, 

 1 -30-1 -45 times as long as broad, o-56-o-6o the width of the broadest part. Fourth tergite 

 densely punctured, its hind margin straight. Fifth tergite the longest, as long as broad or 

 slightly longer than broad, with ovipositorial furrow very deep and with its narrow apex 

 reaching base of tergite, its dorsum, in lateral view, distinctly sloping caudad beyond basal 

 third. Ovipositor sheaths nearly reaching base of fifth tergite. 



(J. Unknown, but probably recognizable on similar colour pattern and mesoscutal carina. 



Biology. According to a letter from Mr J. Ghesquiere the Zairean specimens 

 were reared from Xylocopa sp. (Apidae), one of them from a nest in a bamboo 

 stem.
