Like the type of the species, but with, large glabrous patches on 

 the 2nd and 3rd abdominal segments. The head is even larger than 

 in the type, in the 21. measuring 5-2 mm. wide by 5*9 mm. long (in- 

 cluding the mandibles). Forel says that apart from the above 

 characters it is exactly like the type species. I have a specimen 

 which is undoubtedly to be referred to this variety which has the 

 head and thorax very dark blood-red, and the abdominal pilosity 

 paler than in the type, more reddish ochreous than fulvous.

"$. Very much like fulvopilosus but smaller, dark ferruginous, the 

 abdomen black, head nitidulous, more finely reticulate, the sparse 

 puncturation deeper, the scale thinner and more procumbent, pilosity 

 of abdomen pale flavous, the base glabrous, the glabrous patches on 

 the 1st, 2nd and 3rd segments much larger than in fulvopilosus. 

 Length, 9*5-13 mm. Damaraland." 



The £ minor has the front of the pronotum from shoulder to shoulder 

 sharply marginate.

2J., (hitherto undescribed), 15-16 mm. Head, thorax and flagellum 

 dark blood-red or brownish red, the anterior half of the head, the 

 scapes, legs and mandibles very dark reddish brown. Abdomen 

 black. The pilosity of the abdomen is slightly darker than in flavo- 

 pilosus, ochreous and not at all reddish as in the type fulvopilosus. It 

 is much more dense than in either of those forms and the glabrous 

 patches are entirely absent. The head is very large, as in the var.
