94 PKOCEEDINGS OF THE ISTATIONAL MUSEUM vol. 7r, 



Len^h 14—17 mm. Described from one male and four females 

 (includin<>: type and allotype). The type was collected by R. H. R. 

 Stevenson at Bulawayo, South Rhodesia, and the allotype bears the 

 label " D. O. Afrika, Tabora, 7. 08, Wint«rens S. G." The paratypes 

 bear a common label, " Victoria-Nyansa, I. Ulierewe, Conrads S. G."

Type (male). — Black: labrum; clypeus; scape; frons, except two 

 narrow vertical lines connected by a third line across the frons; 

 broad anterior orbits; posterior orbits; pale^ suffused in many places 

 with ferruginous. Greater part or prothorax; tegulae; short line on 

 scutum above tegula; legs, except basal segments; seventh tergite; 

 apical border of sixth and to a slight extent that of the fifth : 

 feri^glnous. Lateral angles of propodeum; widely interrupted 

 fasciae on tergites 1-5 : yellows 



The fiagella are missing and the tarsi are broken on all legs except 

 one of the posterior pair. The anterior femur below bears a broad 

 pale stripe separating the black at the proximal end and extending 

 almost to the apex of the segment; and each anterior coxa bears a 

 large, pale spot. The middle femur is smooth; the middle tibia is 

 slightly curved; and the middle metatarsus, on its inner side, near 

 the proximal end, bears a small but quite evident swelling or pro- 

 tuberance. The apex of the terminal segment of the posterior tarsus 

 is black. The second sternite bears a small sharp-pointed process 

 and the sixth a prominent bluntly pointed process, whose apex extends 

 beyond the apical border of the sternite and whose sides are fer- 

 ruginous in color. The seventh bears a pair of prominent lateral 

 basal carinae. The seventh tergite is triangular in outline, truncate 

 at apex, and slightly carinate on dorsal midline. 



The allotype (female) very closely resembles the type in color 

 and the character of the maculations. It diifers in that only the 

 labrum and clypeus are pale; that the frons, except for an area 

 above the anterior ocellus, is wholly ferruginous; that the lateral 

 angles of the propodeum are not maculated; and that the macula- 

 tions of tergites 1-5 are pale with a tinge of ferruginous instead of 

 yellow. The flagella are very light ferruginous. The sixth tergite 

 IS darkly ferruginous, slightly sinuate on the sides, broadly rounded 

 at the apex, and covered almost to the apex with short, stout, spine- 

 like hairs. The disk of second sternite is shining and bears numer- 

 ous punctures.
