the base and two and a half times wider there than long, the posterior 

 corners feebly dentate. The declivity is nearly as long as the dorsum. 

 Scale of petiole narrower than in the $, the inner spines much less 

 divergent and shorter, shorter than the interval between their bases 

 (as long as the interval in the $). Wings deeply tinged with brown, 

 nervures and stigma dark brown. 



S. Rhodesia ; fairly common. The nest is made in the ground, 

 under stones. The entrance is surrounded by an irregular, cup-like 

 wall about 1 to 1| inches high, made of woven pieces of grass-blades 

 and similar material. Like all the members of this genus, this ant 

 is a timid insect. It climbs trees and shrubs, and tends Aphids, 

 Coccids, etc.

5, 10-11 mm. Head and thorax subopaque, petiole and abdomen 

 very shining. The sculpture on the head and thorax more evenly 

 and a little more strongly striato-rugose than in the type of the 

 species, not hidden by the pubescence which is exceedingly sparse 

 and inconspicuous. Abdomen microscopically reticulate, without 

 pubescence, pilose only on the apical margins. Eyes nearly flat, 

 otherwise the head is like that of rugulosa. The sides of the pronotum 

 behind the spines parallel over the greater part of their length, not 

 gradually convergent behind as in rugulosa. The dorsum of the 

 thorax is a good deal more convex, especially on the posterior half 

 than in rugulosa, the dorsum of the epinotum sloping more steeply 

 downwards ; the epinotal teeth somewhat wider and curved more 

 upwards. The inner spines of the scale less divergent than in the 

 type of the species, which it otherwise resembles. 



"$, 10 mm. Thorax very gibbous in front. Pronotal spines 

 half as long as in the $. The inner spines of the scale half as long as 

 in the $, only twice as long as the outer spines, the latter as strong 

 as in the g. The mesonotum is very shining, very feebly reticulate, 

 like the abdomen. The scutellum and epinotum have a much coarser 

 sculpture and are dull, as in the £. The scapes, and particularly the 

 tibiae, with some erect pilose hairs. Dealated. Otherwise like the £.
