than the scutellum ; the posterior margin of the latter semicircular. 

 Dorsum of epinotum convex lengthwise, three times wider than long 

 in the middle, armed with 2 acute and small triangular teeth ; the 

 declivity subvertical. Petiole as in the ^ , but the anterior angles of 

 the 1st segment less rounded. Abdomen with subacute lateral angles 

 at the base. Wings hyaline, slightly tinged with yellow, nervures 

 and stigma dark oehreous. 



$ . 4 mm. Dark brown, petiole and abdomen paler than the 

 thorax ; legs, mandibles and antennae dark ochreous-yellow, the legs 

 also somewhat brownish. Shining. Head finely striate longitudinally. 

 Mesonotum very finely striate in the middle, the striae on each side 

 converging posteriorly. Scutellum very finely striate at the sides and 

 in the middle, with a broad and shallow transverse impression at the 

 base. The scape as long as, or a little longer than the 1st joint of the 

 flagellum ; the latter as long as wide, the 2nd-5th joints wider than 

 longj the remaining joints very little longer than wide. First segment 

 of petiole a little longer than wide, the sides subparallel, the anterior 

 face oblique and hardly longer than the upper face; 2nd segment 

 subcircular, not very convex above, barely wider than the 1st. Wings 

 with pale yellow nervures.

The £ has a sharp tooth below the 1st segment of the petiole as in 

 race hottentota of C. Kneri, to which this variety appears to be closely 

 allied. Apart from the greater size, the only appreciable differences 

 lie in the wider head, shallowly but distinctly emarginate behind, the 

 more clearly marginate thorax, the longer spines and the wider 1st 

 segment of the petiole. The sculpture of the thorax is also a little 

 finer than in hottentota, and the surface duller.

" ^ . 22-3 mm. Mandibles striate. Clypeus without a carina ; 

 the anterior margin not emarginate in the middle. Head rectangular, 

 the angles rounded, somewhat longer than wide, with convex sides. 

 Eyes placed a little behind the middle of the sides. The frontal 

 sulcus is continued very shallowly as far as the posterior margin of 

 the head, the latter slightly emarginate. The scape does not reach 

 quite as far as the posterior margin. Club of antenna almost 2- 

 jointed in the ^ major, 2-jointed only in the ^ minor; 2nd— 5th joints 

 of the flagellum wider than long. Pronotum barely marginate at the
