First abdominal segment nearly twice as wide as the node of petiole, 

 and with a small truncate projection below at the extreme base 

 Abdominal constriction well marked. Second segment slightly wider 

 than the 1st, but not longer. Anterior tarsi with thick golden - 

 brown hairs beneath. 

 Transvaal. 



Var. ehodesiana, Eorel. 

 Ann. Soc. Ent. Belg., vol. 57, p. 109, 1913. 



This differs from the type in its larger size, 13 mm. g , and more 

 abundant pilosity. The node of the petiole is not so smooth, and is, 

 like the abdomen, duller. 



$ (hitherto undescribed). 10 mm. Head black; mandibles, 

 clypeus, antennae, legs, and last abdominal segment occasionally, 

 reddish yellow. Thorax dark castaneous brown, pronotum somewhat 

 lighter. Epinotum, petiole, and abdominal segments reddish brown, 

 the apical margins of the latter testaceous yellow. 



Head transverse ; clypeus produced and raised in the middle 

 anteriorly. The frontal carinae are very short and indistinct. 

 Eyes very large and reniform. Antennae filiform, reaching back 

 as far as middle of 2nd abdominal segment. Pronotum only slightly 

 exposed dorsally. Mesonotum with a central impressed line, 

 broken in the middle ; the Mayrian furrows distinct, the lateral ones 

 less so. A crenate sulcus separates the mesonotum from the 

 rather gibbous scutellum. Epinotum rounded, the declivity with a 

 raised central line. Node of petiole sloping in front, rounded above 

 and with a faint median impression, vertical behind and longer than 

 wide. Seen from above, the petiole has a minute tooth on each side 

 at the extreme base, and a slightly larger tooth beyond the latter. 

 The ventral lamella is produced into a very short obtuse angle. First 

 abdominal segment beneath with a truncate process at the extreme 

 base similar to that of the $ . Abdominal constriction distinct. 

 Legs long and slender. Wings hyaline, nervures yellow, stigma 

 dirty yellow. Body rather shining and covered with a silky grey 

 pubescence. There is a sparse pilosity on the margins of the last 

 three abdominal segments. Head and thorax very finely, closely, 

 and shallowly punctured ; base of epinotum a little more coarsely 

 and rugosely punctured. Abdomen impunctate. 



This variety is common round Bulawayo. The nest is generally 

 placed under a stone, with several entrances which are surrounded 

 by loose earth ; the male is very common at light.
