Race tablense, Forel. 

 Bull. Soc. Vaud. Sc. Nat., vol. 50, p. 223, £ , $ , <J , 1914. 



£ . 2-2 - 2 mm. Colour as in var. mossamedensis. Similar to race 

 ladismithensis, but the head is a little less elongate, the thorax more 

 constricted between the meso- and epinotum. The epinotal teeth are 

 almost obsolete, being represented by two small ridges. The frontal 

 carinae are much shorter, without a trace of scrobes below them. 

 Otherwise like the race ladismithensis. 



$ . 2"6 mm. Blackish-brown. The mesonotum and scutellum 

 feebly and longitudinally striate ; the dorsum of the declivity steep, 

 the epinotal teeth distinct, acute, triangular, not quite as long as their 

 basal width. Deiilated. Otherwise like the ^ • 



3 . 2'7 mm. Black; legs, antennae, and mandibles dirty yellow. 

 Head subquadrate, widest in the middle, a little wider behind than 

 in front. Scapes extending back as far as the posterior ocelli. Eyes 

 large, convex, occupying the anterior third of the head, not touching 

 the base of the mandibles. Head dull, very finely and closely reticulate- 

 rugulose. Mesonotum and scutellum very faintly and longitudinally 

 striate or aciculate, shining. Epinotum reticulate-striate, dull ; nodes 

 feebly reticulate and slightly shining. Abdomen smooth and shining. 



Table Mountain, nesting under stones. This is one of the few 

 species which appear to be able to hold their own against the invading 

 Iridomyrmex humilis, and it is found at the lower levels of the 

 mountain where humilis has succeeded in di-iving out almost all 

 other kind of ants.
