sutural ones somewhat convex ; under side aciculate punctate ; 

 anterior tibiae eight-dentate outwardly. 



Length 8 mm. ; width 5 mm. 



Hab. Transvaal (Waterberg). 



This species is the only South African one known to me having 

 eight-dentate fore tibiae, and is thus easily identified. It is not 

 unlike in general appearance B. matabele, but in the latter the 

 scutellum is smooth. 



BOLBOCEEAS NIGRUM, n. sp. 



Male : Black, shiny, under side clothed with a flavescent pubes- 

 cence ; antennae chestnut-brown ; labium with a plain, transverse 

 ridge between the apex and the junction with the clypeus, edge 

 of the latter distinctly carinate, in a line with the apex of the genae 

 is a triangular ridge reaching from side to side with the median 

 parts and the angles plainly acuminate, beyond the middle of the 

 frontal part is a transverse ridge which does not reach from side 

 to side, and the space between the two ridges is depressed and 

 nearly smooth, the clypeus is coriaceous, the apex of the head 

 punctate ; prothorax declivous in the anterior part, deeply impressed 

 rather than excavate there, the depression being nearly as broad 

 as long ; from the median part to the base is a punctate sulcus 

 deepening towards the base, the impression is vaguely punctate ; 

 on each side of the median sulcus is an impunctate area, but the 

 punctures on the sides are deep and closely set ; scutellum as long 

 as broad, ogival, and closely and deeply punctate for four-fifths 

 of the length ; elytra deeply and closely punctate striate, intervals 

 smooth, the dorsal ones slightly convex ; under side aciculate 

 punctate ; anterior tibiae nine-dentate. 



Length 7^ mm. ; width 5J mm. 



Hab. Southern Bhodesia (Salisbury ).
