218 Annals of the South African Museum. 



The type species does not appear to have been recorded from South 

 Africa, but is represented by the following forms. 



Eace boerorum, Forel. 

 Ann. Soc. Ent. Belg., vol. 54, p. 442, £ , 1910. 



^ • 1'4-1"7 mm. Pale brown to dark brown, the -mandibles, 

 antennae and tarsi lighter. Very smooth and shiniug, with a very 

 sparse and pale pilosity. This race differs from the type in the 

 following particulars. The head is longer and narrower than in the 

 type, rectangular, with the sides almost straight (convex in the type). 

 The eyes are placed within the anterior third of the head. The nodes 

 are a little thicker, and the 1st node is but slightly convex below. 

 The thoracic impression is stronger and wider. The epinotum is a 

 little more convex, and the carinae on the clypeus are less distinct and 

 further apart in front. 



$ . 3 2 mm. Black, legs and antennae brown, tarsi and articula- 

 tions of the legs brownish, mandibles rusty brown. Head, mesonotum, 

 and scutellum very sparsely and finely punctured; the rest of the 

 body inipunctate. Abdomen and sides of the nodes sparsely covered 

 with a thin, long and pale pilosity. Head longer than wide ; the 

 ocelli small. Thorax narrow, much narrower than the head. Pro- 

 notum almost vertical in front, very slightly exposed in the middle, 

 but more at the shoulders. Mesonotum one-third longer than wide ; 

 scutellum much longer than wide, and a little longer than half the 

 mesonotum. Dorsum of epinotum very short, merging gradually into 

 the declivity, which is very steep, transversely concave, feebly and 

 transversely striate. Petiole as in the ^ . Abdomen elongate, the 

 basal angles of the 1st segment pronounced, 1st segment as long as 

 wide, the remaining segments wider than long. Deiilated.

This form is unknown to me, and I am therefore obliged to re- 

 produce the author's description, which is unfortunately based on a 

 comparison with a Madagascan species. 



" Closely allied to imerinense, Forel, from which it differs by the 

 more angular epinotum, due to the more marked lateral ridges, and 

 above all by the stronger petiole, the 1st joint of which has a longer 

 peduncle ; the nodes more robust, the 2nd wider behind than in front,
