 imposed .... I attribute with some doubt to this species two $ minima 

 from Kimberley, in spite of considerable differences in the sculpture 

 and shape. 



§, 4* 5-5 mm. Head parallel-sided, not much longer than wide, 

 rounded behind, with large eyes placed far backwards. Clypeus 

 emarginate on each side, feebly produced and truncate in the middle, 

 very obtusely carinate, fringed with a few hairs. Pronotum not 

 margin ate, rounded in front; the thorax is fairly robust in front and 

 is narrowed behind as far as the meso-epinotal suture ; the epinotum 

 is parallel-sided, somewhat flattened above ; the dorsal profde of the 

 thorax forms a continuous arc, but with the angle of the epinotum 

 very obtuse. Scale thicker than in the %, but of the same shape. 

 Head and thorax shining, very finely and superficially punctulate, 

 with some scatt ered pubescent punctures, but with very few long hairs. 

 Pubescence and setae on the tibiae as in the %. The scape extends 

 beyond the posterior margin of the eye by half its length. Colour 

 pale testaceous, the head and middle of the abdominal segments 

 darker."

"2J-. The lobe of the clypeus has 5 teeth, owing to each of the 

 lateral teeth being divided into two. Otherwise agrees well with the 

 description of the type species, but the scale is acuminate. 



$ minor, 7 mm. The 5 teeth of the clypeus smaller but distinct. 

 Scale acuminate. Eyes very large, a little longer than their distance 

 from the occipital margin. Entirely yellow ; abdomen somewhat 

 brownish yellow. Metanotum not defined. Mandibles 5-dentate, (6- 

 dentate in the %). Natal, (Haviland). 



Var. pretiosa, n. v. 



%, 10 mm. Head and thorax yellowish brown-red, (pale burnt 

 sienna), the anterior corners, the clypeus and the vertex (excepting 

 the anterior half of the space between the frontal carinae), brown 

 or piceous, the posterior half and the sides of the thorax and the 

 petiole darker or reddish brown ; abdomen piceous, the apical margins 

 of the segments widely testaceous. Legs ochreous, tarsi and antennae 

 ferruginous. Mandibles very shining all over, with 5 teeth, fairly 

 abundantly punctured, the punctures small but deep. Lobe of the
