punctulata. Second node narrow, barrel- shaped, widest a little behind 

 the middle, one-fourth longer than wide, three-fourths wider than the 

 1st. 



? . 8*3 mm. (hitherto undescribed). Very similar to punctulata 

 but larger and darker. The head is a little wider, duller and more 

 closely striate, the spaces between the striae closely reticulate and 

 crossed by transverse ridges. The epinotum is longer and transversely 

 concave almost from its base downwards, the dorsum very short and 

 steep, margined at the sides. Epinotal teeth slightly incurved, 

 larger than in punctulata. The chief distinction between this species 

 and punctulata lies in the shape of the 2nd joint of the petiole, which 

 when seen from above is biconvex, a little wider in front than behind, 

 and not at all angularly produced at the sides. Otherwise like 

 punctulata. 



S. Rhodesia, fairly common ; Ladismith, Cape Prov. and Botha- 

 ville, O.F.S. (Brauns). (S.A.M., E.M., G.A. colls., type of ? in my 

 collection.) 



Pheidole tenuinodis, Mayr, var. sipapomae, n. v. 



1/. 5'3 mm. Larger than the type of the species. Sculpture of the 

 head similar but stronger, the mandibles also much more deeply 

 punctured. The hind margin of the head less widely but more deeply 

 emarginate. Promesonotal suture more clearly defined. Dorsum of 

 the epinotum wider and relatively shorter, hardly one-third longer 

 than wide at the base of the spines. Dorsal edge of the 1st node 

 not emarginate, the sides of the 2nd node much less angular. 

 Legs reddish-ochreous, abdomen piceous, the apical margins of the 

 segments testaceous. Otherwise like the type of the species. 



5 • 3 - 6 mm. Colour a little darker, and the head more strongly 

 sculptured than in the type of the species. Posterior fourth of the head 

 finely reticulate. Clypeus sharply carinate. Meso-epinotal suture 

 much deeper and wider. Otherwise like the type of the species. 



Sipapoma, Umgusa River and Victoria Falls, S. Rhodesia. 



The 1/ 1/ from Victoria Falls are a little larger than the others 

 (5 - 6 mm.) and a good deal darker, but otherwise identical. The nest 

 has several entrances, surmounted by irregular and rather high 

 craters. (S.A.M., R.M., G-.A. colls. ; types in my collection.) 



P. victoris, Forel. 

 Ann. Soc. Ent. Belg, vol. 57, p. 127, 1/, £, 1913. 

 1/. 4-2-4-5 mm. Reddish -brown. Abdomen pale brown or 

 yellowish-brown with the apical margins of the segments much paler.
