author raises it again to the rank of a race. I am unable to obtain 

 access to the original description of Mayr, but from Emery's table of 

 this group in the Ann. Soc. Ent. France, vol. 63, p. 48, the follow- 

 ing characters can be extracted : — 



The two faces of the epinotum form a distinct though considerably 

 rounded angle, as in cinctellus. It differs from the latter in having 

 the pubescence of the 2nd abdominal segment convergent towards 

 the middle line, but not undulate, the hairs on the basal half of the 

 segment not transverse in direction, merely oblique like the rest of the 

 pubescence. 



Certain specimens from Natal, named for me by Dr. Forel as of this 

 race, do not agree with the above diagnosis, and should be referred to 

 the race zulu.

"y, 6'5-10-5 mm. Differs from flavomarginatus by having the pubes- 

 cence on the abdomen denser and of a golden colour, whereas it is 

 greyish in the race. The pubescence of the abdomen is also more 

 undulated, almost as much as in cinctellus. The front of the head 

 is much darker. Mandibles flagellum, tibiae and tarsi of a dark 

 brownish red. Tibiae even more compressed than in flavomarginatus 

 (not so very much in cinctellus and its varieties). Otherwise like 

 flavomarginatus. ' ' 



The pubescence on the abdomen would be more correctly described 

 as being of a bronzy-golden colour. The anterior margins of the head 

 and the mesonotum have a more or less reddish tinge, and the cheeks 

 are castaneous brown. The erect pilosity on the head and thorax 

 of a darker yellow than in cinctellus. The sides of the head less convex 

 than in that race.

Smith's description is valueless as it applies equally well to several 

 forms of this species. Emery (Ann. Soc. Ent. France, vol. 63, p. 49) 

 records this race from Pretoria, Hamman's Kraal, Hebron and
