entire absence of the meso-epinotal suture. The floor of the punctures 

 without any golden reflection. 



Bulawayo, living in the nests of Platythyrea cribrinodis, apparently 

 in plesiobiosis. (S.A.M., R.M., G-.A. colls.), type in my collection.

" $ . 2 mm. A little smaller than the type of the species. 

 Entirely pale yellow, with the same goldVn punctures. Epinotal spines 

 shorter, only a little longer than their basal width. Nodes of the 

 petiole less broad, the 2nd only twice as wide as long, the 1st one and 

 a half times wider than long.

Var. fusciventris, Forel.

"£. 22-2 - 5 mm. A little smaller than the type of the species. 

 Epinotal spines distinctly shorter, subdentiform but acute, very little 

 longer than their basal width. The same golden punctures as in the 

 type. The sculpture a shade finer and more rugose. Nodes a little 

 wider. Of a darker yellow and more brownish colour than that of the 

 type. Abdomen brownish. Otherwise like the type species." 



The thorax is narrowed between the meso- and epinotum, but there 

 is no trace of the suture dorsally. The margins of the thorax and the 

 edges of the epinotal teeth are more darkly coloured. The basal third 

 of the abdominal segments paler than the remaining portions. Some 

 of the hairs are sinrple, the rest are shorter and trificl. 



Bulawayo, like var. bulawayensis, also nesting in and near the 

 galleries of Platythyrea cribrinodis. (S.A.M., R.M., G.A. colls.)

" 9 • 3" 6-4 mm. Darker than the type of the species, dark brown. 

 Frons, cheeks, mandibles, antennae, legs and transverse bands on the 

 posterior portion of the abdomen, yellowish-red. Head less emarginate 

 behind and more narrowed in front. The 1st node is more rounded 

 at the sides, and above all, the 2nd node is differently shaped, being 

 obtusely and conically pointed laterally, less flat above, forming more 

 of a rounded, transverse edge. Otherwise like the type."
