of the scape, flagellum, articulations of the legs and the tarsi cas- 

 taneous ; £ minor brown, mandibles, flagellum and tarsi yellowish- 

 brown ; mandibles strongly striate ; head very closely striate. Thorax 

 as in Aphaenogaster structor, striate ; epinotum with two tubercles ; 

 nodes striate or rugulose, the 2nd node smoother ; abdomen smooth 

 and shining. . . . The yellowish and outstanding pilosity is 

 moderate, on the legs fairly abundant. The mandibles are fairly 

 coarsely and longitudinally striate, in the smaller $ £ with about 

 12 teeth, edentate in the larger $ $ . The head has a silky gloss, 

 and in the $ major is very closely and longitudinally striate, the 

 striae curving round the eyes and antennae sockets ; in the $ minor 

 the striae are less regular and unequal, weaker and not so straight on 

 the frons, transverse on the vertex. The feebly shining thorax is like 

 that of A. structor. The pronotum above is transversely and at the 

 sides longitudinally striate ; the mesonotum rugulose ; the epinotum 

 above transversely, at the sides longitudinally striate, not quite dentate 

 above on each side, but nevertheless angularly dilated. The nodes are 

 rounded above; in the $ major transversely striate and partly rugulose 

 at the sides ; in the £ minor very shallowly rugulose, almost smooth 

 and shining. Abdomen smooth and very shining. Cape of Grood 

 Hope. 



" 9 • 15 mm. Brownish-black, head dark ferruginous, partly cas- 

 taneous ; articulations of the legs and tarsi rufescent ; very sparsely 

 pilose; head as in the £ major; pronotum densely and longitudinally 

 striate, mesonotum shining, longitudinally striolate, scantily punctured, 

 and with three large and smooth patches ; scutellum shining and 

 almost smooth, the sides striate; epinotum elongate and bituberculate, 

 the sides strongly striate ; nodes of the petiole striato-rugulose ; 

 abdomen very shining, smooth and almost glabrous. 



" $ . 8 - 3 mm. Black, shining, mandibles and articulations of the 

 legs and tarsi fuscous ; not very densely pilose, the abdomen sparsely 

 pilose ; mandibles striate, clypeus ^with transverse rugae ; cheeks, 

 antennal foveae and the frons partly longitudinally striate, the middle 

 ■of the latter finely rugulose ; the vertex near the anterior ocellus 

 radiately rugose, behind and outside the ocelli very finely and shallowly 

 rugulose-punctate ; pronotum finely rugulose-punctate ; mesonotum 

 longitudinally rugoso-striate, with some scattered punctures, smooth 

 in the middle in front ; disc of scutellum smooth ; epinotum oblique, 

 obtusely tuberculate, finely and transversely striate at the base ; sides 

 of thorax striate ; nodes of petiole very finely rugulose ; abdomen 

 smooth in front, very finely and shallowly coriaceous behind ; wings 

 subhyaline, stigma and costa ochreous."
