tooth, the carina underneath is sharp, but not serrate, and is ciHate ; 

 intermediate femora serrulate all along the lower margin, inter- 

 mediate tibiae slightly bi-incised inwardly ; posterior femora serrate 

 all along the margin like the intermediate ones (fig. 6), posterior 

 tibiae normal. 



Female : The shape of the body is a little more convex, the 

 tubercle on the vertex of the head is more developed, and the 

 depressed longitudinal median line of the prothorax is less visible 

 and shorter. 



Length 20-21 mm. ; width 11-11^ mm. 



This species differs from 0. confusus in the general facies, which 

 is shorter and more convex ; the tooth on the under part of the fore 

 tibiae of the male is not so much developed, and the serration of the 

 hind femora is different ; the intermediate femora are serrate, w^hich 

 is not the case in 0. confusus. 



Hah. The whole of Cape Colony, but more abundant in the 

 eastern than in the western part ; Natal (Durban, Newcastle, 

 Estcourt), Transvaal (Potchef stroom) .

 vertex moderately elongate, depressed on each side, posterior margin

 convex, broader than long, roughly punctured in front and between 

 the basal foveae, while the punctures on the disk are deep and not 

 very close and are very slight behind, base crenulate, nearly straight 

 between the foveae and marginate, the foveae are close to one another,

 the striae obsoletely punctate transversely, intervals plane, sparety
