l % major. Very similar to Bertolonii, and like it in colour and 

 sculpture, but larger and with the cheeks barely pilose, without 

 elongate foveae, only with minute pubescent points, the clypeus 

 with a few piligerous foveae, its lobe truncate and subemarginate ; 

 the scale of the petiole is reddish, higher and thinner than in Ber- 

 tolonii, its sides convex, its dorsal edge acuminate; the femora fus- 

 cous. 9 mm. long. Head 2*8 X 2*8; scape 2-2; posterior femur 2 - 5. 

 Capetown, a single specimen. 



Resembles Bertolonii so much that it might be regarded as only 

 a race of the same. However, the size, the absence of piligerous 

 foveae and erect hairs on the cheeks, as well as the narrow and 

 biconvex scale with its trenchant edge, sufficiently characterise this 

 ant. The shape of the head and thorax is about the same as in 

 Bertolonii '."

Qj.. 14-17 mm. Black, the apical margins of the abdominal seg- 

 ments narrowly testaceous and translucent, flagellum and tarsi dark 

 reddish brown. Entirely dull, the fundamental sculpture of the head 

 like that of maculatus, but somewhat coarser, the floor of the spaces 

 between the reticulations quite dull. The sides of the head and 

 clypeus fairly abundantly sprinkled with shallow pubescent foveae. 

 Thorax finely and closely reticulate-punctate, abdomen and petiole 

 finely and transversely rugulose, but much more strongly than in 

 maculatus and its races. Legs and scapes slightly shining, modera- 

 tely punctured. The whole body, legs and antennae clothed with a 

 fairly abundant, long and reddish yellow pubescence, oblique on the 

 legs and abdomen, almost decumbent elsewhere. Pilosity long, ful- 

 vous, fairly plentiful on the abdomen, pronotum and clypeus, sparse 

 elsewhere, absent from the cheeks. 



Head about one-eighth longer than wide, widest behind, the sides 

 moderately convex, the posterior margin deeply concave, the occipi- 

 tal lobes rounded but fairly prominent posteriorly. Mandibles 

 strongly punctured, moderately shining but dull near the base, 

 armed with 6 or 7 teeth. Clypeus sharply carinate, produced in 

 front into a rectangular lobe the margin of which is crenulate. 

 Frontal carinae slightly raised and trenchant. Eyes placed just be- 

 hind the middle of the sides. Scapes rather long, extending beyond
