wide and as long as wide. Fairly shining, lightly and finely reticulate 

 all over ; posterior half of abdomen smooth. Pilosity as in the "2/ . 

 Reddish-yellow, head brownish-yellow. Abdomen yellowish, with 

 brown apex and often with brown sides. 



" $ • 6*5 mm. Mandibles, clypeus and scrobe as in the %. Head 

 trapezoidal, wider than long, narrower in front, the posterior margin 

 straight. Eyes in the anterior third. The scape does not quite reach 

 as far as the posterior margin of the head. Mesonotum somewhat 

 wider than the head, flat above, with two lateral longitudinal lines. 

 Spines nearly as long as the dorsum of the epinotum, blunt at the 

 apex. Petiole as in the 2/, but the even wider 2nd node has the 

 sides acutely conical. Head coarsely, mesonotum finely and evenly 

 rugose lengthwise. Epinotum smooth above; sides of thorax coarsely 

 rugose. Petiole and abdomen as in the 1/ , but the first abdominal 

 segment is nearly dull and closely reticulate-punctate over its basal 

 half. Pilosity as in the If. . The exserted hairs on the body very 

 short. Yellowish-red ; legs and base of the abdomen dirty yellow, 

 the rest of the abdomen dark brown. Deflated. 



" $ . 5-5 2 mm. Mandibles bidentate. Head, excluding the eyes, as 

 wide as long, narrowed like a trapezoid towards the articulation 

 behind. Dorsum of epinotum much longer than the declivity, ending 

 in two blunt tubercles. Scape as long as the second joint of the 

 flageHum. Fairly shining, finely and irregularly reticulate or rugulose. 

 Pilosity as in the 1/ and £' . Brownish-yellow. The vertex and 

 abdomen in part brownish. Wings tinged with brownish-yellow, 

 nervures brownish-yellow, stigma brown. 



"Khakhea, Kalahari (Schultze), in sand. Perhaps allied to caffra, 

 Em., but the latter has the head strongly depressed behind in the 1/."

"If.. 7 mm. Closely allied to speculifera-crassinoda, Em., and 

 particularly to its var. cubangensis, Forel. It differs particularly in 

 its much longer scape, which almost extends back to the posterior 

 third of the head, (to the posterior half in speculifera), also in its head, 

 which is much longer than wide, the sides but slightly convex (very 

 convex in speculifera and only little less so in cubangensis) and in the 

 mesonotum, which has a stronger torus behind, and the pro-mesonotal 

 sutui'e, which is deeper. The eyes are also more convex. The head is 

 in great part dull, with a strong and sparse puncturation on the 

 occiput and vertex. The sides of the occiput alone are slightly shining.
