Race cognatus, var. boera, Forel. 

 Schultze, Reise Stidafrika, vol. 4, p. 27, §. 1910. 



"^. 8-13 mm. Differs from the type of the race by the brighter 

 and entirely rusty yellow-red or brownish yellow colour, even in the 

 largest Q. Scapes, tarsi and mandibles somewhat darker brown. 

 Otherwise the shape, sculpture and pilosity agree entirely with cognatus. 



9, 13 mm. Entirely brownish yellow like the §, dealated. Little 

 Namaland, Steinkopf and Kammagas, (Schultze) ; in a rotten tree- 

 stump. The race Ballioni, Forel (Ann. Soc. Ent. Belg. vol. 48, 

 p. 176, 1904, habitat, Port Elizabeth), is only a darker variety of the 

 true cognatus, at the time insufficiently known to me, differing from 

 the same in having a darker ^ minor, and in the narrower shape, 

 (the head of the ^ minor being also shorter and less narrowed behind). 

 All varieties of cognatus have hirsute cheeks." 



Race intonsus, Emery. 



R. C. Acad. Sc. Bologna, p. 29, & 1904-5. 



"^. Of the size of maculatus i. sp. (12*5 mm. long); the head of 

 the Qj. is less wide (3 - 4 X 3 - l mm.), narrower apically, (greatest 

 length of scape 2*8 mm., of posterior tibiae 3'5 mm.). In the Q 

 minor the sides of the head, from the eyes to the occipital margin, 

 are straighter than in maculatus. The sculpture is stronger and the 

 integument duller all over. The sides of the head have a stronger 

 sparse puncturation, the punctures bearing short, straight hairs. 

 The tibiae are setose below. Colour entirely pale yellow in the 

 ^ minor ; in the § media, the abdomen is more or less brown ; in 

 the Oj. the thorax is ferruginous, the head darker, the abdomen 

 brown or black, either without spots or with indistinct spots of a 

 brownish yellow and darker than in maculatus. Cape Prov. and 

 Transvaal." 



Race baynei, n. race. 



Qj.. 108 mm. Head and scapes black, flagellum reddish brown, 

 thorax black above, brown at the sides, epinotum black above, 

 ochreous at the sides and on the declivity; petiole, coxae and femora 

 ochreous (of a paler colour than in the type of the species), the 

 tibiae and tarsi dark brown. Abdomen entirely blackish brown, 

 only the extreme apical margins flavous and translucent. Sculpture 

 much more superficial than in the type of the species, the whole 

 body more shining, especially the head. Pilosity brownish yellow,
