the dorsal edge thin and feebly emarginate in the middle. Tibiae 

 compressed, the sides not canaliculate, feebly setose below. 



Some of the 9|. Qj., 13 mm. long, are intermediate between the 

 largest and the £ media and have the head narrower behind than 

 in the largest Qj. Q[, but neverthess still triangular. 



^ media, 12 mm. Dorsum of thorax brown, the femora ochreous 

 over the basal two-thirds. Head oblong, a little wider behind than 

 in front, widest behind the eyes, two-sevenths longer than wide, the 

 sides moderately convex, the posterior margin feebly concave. Eyes 

 placed behind the middle of the sides. Mandibles sharply punctured, 

 the masticatory margin ferruginous. Clypeus more sharply carinate 

 than in the Qj., but the anterior margin of the lobe barely crenulate. 

 The two faces of the epinotum less distinctly delimited than in the Qj.. 

 Anterior face of the scale convex, the posterior face flat, the dorsal 

 edge entire. 



§ minor, 10-11 mm. Like the y media, but with the thorax 

 paler and the yellow colour of the femora extending almost to their 

 apices. Head nearly half as long again as wide, the sides in front 

 of the eyes straight and slightly convergent anteriorly, the sides be- 

 hind the eyes form with the posterior margin a continuous con- 

 vexity; hardly narrower in front of the eyes than behind them. 

 Otherwise like the § media. 



9, 16'5 mm. Colour and pilosity as in the Qj., a narrow trans- 

 verse band at the base of the epinotum and the declivity of the 

 same brownish ochreous. Head a little longer than wide, subqua- 

 drate, the posterior margin straight and one-fifth wider than the 

 anterior, the sides slightly convex posteriorly, the posterior angles 

 narrowly rounded. Mesonotum and scutellum fairly shining, the 

 head and epinotum moderately so, the abdomen very shining as in 

 the Qj.. Scutellum convex lengthwise and transversely, a little higher 

 than the mesonotum. Dorsum of epinotum shorter than, and mer- 

 ging gradually into the vertical declivity. Both faces of the scale a 

 little more convex than in the Qj., the dorsal edge not emarginate. 

 Deflated. 



George, near Knysna Forest, Cape Prov. (Dr. H. Brauns). 



This race was determined by Dr. Forel as Fornasinii Era., but it 

 is quite distinct from that race in several features, e. g. the shining 

 integument, the shape of the head, etc. It approaches race Empe- 

 docles Forel, but the occipital lobes are not angular.
