peduncle, seen from the side bluntly wedge- shaped ; the anterior face 

 of the node vertical, the posterior dorsal face convex and shallowly 

 grooved lengthwise in the middle ; 2nd node wider than the 1st, more 

 or less campaniform. Abdomen elongate ovate, the apical margins of 

 all the segments pale brownish. 



£ media, 7 mm. $ minor, 5-5'5 mm. These differ from the § 

 major as follows : The stria tion of the head and thorax is weaker ; 

 the head is a trifle longer than wide (in the $ major a little wider 

 than long), the sides of the pronotum less convex, the emargination of 

 the posterior dorsal face of the first node less pronounced, the sides of 

 the second node less convex.

" Not exceeding 8 mm., smaller than the race. Head and 

 thorax more or less ferruginous, with the sculpture of the duller 

 varieties of aegyptiaca. On the head the sculpture is close and even, 

 with fine and prominent longitudinal striae, often interrupted and 

 lightly undulated. The thorax is dull ; the epinotum hardly angular, 

 without prominent teeth. Cape Prov." 



The commonest form of capensis in S. Ehodesia has been referred 

 to the above variety by Dr. Santschi, to whom I sent some typical 

 examples of: a series which had previously been determined by Dr. 

 Forel as simple race capensis, from which they obviously differ not 

 inconsiderably in certain features. Nevertheless, they do not quite 

 agree with Emery's variety, since they attain a greater size and have 

 the thorax a good deal more coarsely sculptured than in the few 

 examples of aegyptiaca which I have seen. They are also very much 

 like var. proba (Eorel), to judge by the description only, so that for 

 the present I prefer to place them with the variety to which Dr. 

 Santschi has assigned them. They are characterised as follows : 



$ major. 9 - 5 mm. Head, including the closed mandibles, 3 mm. 

 long X 3 mm. wide. Head, thorax and petiole varying from brick- 

 red to reddish-brown, abdomen piceous, the extreme base of the first 

 segment sometimes with a reddish tinge ; legs brownish-red, the tarsi 

 and tibiae a little darker. The striation of the head is much more 

 feeble than in capensis (i. e. those forms from Willowmore and 

 Durban described above), and the pronotum is transversely rugulose 

 instead of longitudinally striate. The pro-mesonotum is much more 

 convex and much higher above the level of the epinotum, and its
