A Monograph of the Formicidae of South Africa. 183 



hairs. Head widest between the eyes, nearly one-third longer than 

 wide, the posterior angles very rounded. Eyes placed in the middle 

 of the sides of the v head, occupying a little more than one quarter of 

 the latter ; a trace of the anterior ocellus present. Median portion of 

 clypeus raised and produced ; the anterior margin of the protruded 

 area is quadridentate (see fig. 50, Plate V) ; the inner pair of teeth are 

 larger and further apart from each other than they are from the outer 

 teeth. (In the two specimens at my disposal there is a slight asym- 

 metry produced by the sub-division of either the right or the left inner 

 tooth.) The scape extends backwards to the posterior margin of the 

 eyes ; the 1st joint of the flagellum is longer than wide, and is as long 

 as the 2nd-4th joints taken together ; the latter and also the 5th 

 and 6th are wider than long, the remaining joints longer than wide. 

 Frontal carinae short, slightly divergent behind. Mandibles tri- 

 dentate, feebly striato-punctate, the external and internal margins 

 subpai'allel. The dorsum of the thorax is not margined. Pronotum 

 widest anteriorly, flattened above, as long as wide ; mesonotum sub- 

 circular, nearly as long as the pronotum ; pro-mesonotal suture feeble, 

 meso-metanotal fairly well defined. The metanotum is much narrower 

 than the mesonotum and is separated from the epinotum by a deep 

 and wide groove, slightly clathrate laterally. The epinotum is widest 

 at the base, twice as long as wide, as long as the pronotum, the lateral 

 dorsal margins and the brow of the short and oblique declivity, 

 strongly rounded. The peduncle of the 1st joint of the petiole is 

 about half as long as the node, the latter is nearly twice as long as 

 wide. The 2nd joint is bell-shaped, widest posteriorly, and two-thirds 

 wider than the 1st joint. Seen in profile, both joints are very convex 

 above. Abdomen elongate-ovate, 1st segment longer than wide. 

 The femora are swollen in the middle. 



$ . 5 - 5 mm. Differing from the ^ in the following characters. 

 The head is more parallel-sided ; the inner pair of teeth on the anterior 

 margin of the clypeus are much larger, and the outer pair relatively 

 smaller. The pronotum has the anterior angles less rounded, the 

 sides more parallel ; it is distinctly wider than long. The mesonotum 

 is widest in the middle, in front of the tegulae, and one-third wider 

 than long. The scutellum wider than long, two-thirds as long as the 

 mesonotum. The epinotum is wider at the base than it is long, seen 

 from above, reversed trapezoid, not elongately triangular as in the 

 ^ • Three small ocelli are present. Other characters as in the £' .
