minute granules ; the white indument of the pygidium is sometimes 

 divided into patches, the under side is more punctulate than in the 

 male, and the punctures on the inner part of the tibiae are briefly 

 pubescent. 



Length 29-32 mm. ; width 14-15 mm. 



Hab. Southern Bhodesia (Salisbury, Matopos, Manica, Sebakwe) ; 

 Mozambique (Tette) ; Transvaal (Pietersburg).

Mentum hairy, ampliated laterally, somewhat narrowed at the 

 ligular part which is almost quadrately scooped out in the centre 

 with the apical outer angles moderately rounded, the excavation 

 for the insertion of the labial palpi is greatly elongated, beginning 

 at about one-third of the length of the mentum and reaching the 

 apex, and so wide that it can be said to be supra-lateral, maxillae 

 long, inner lobe hairy inwardly and ending in a very sharp, strongly 

 falcate tooth, upper lobe short, sharp at tip, and densely penicillate, 

 in the $ the upper lobe is longer and ends in a hooked tooth ; in 

 the $ the anterior angles of the clypeus are produced into a sub- 

 porrect tooth, and the central part into a triangular horn slanting 

 upwards, dilated at tip into a sub-hamate process on each side, this 

 horn is sharply carinate longitudinally in the centre, the carina 

 branching off on each side along the sub-hamate apical process, the 

 head has above the eye a thick laminate, sub-porrect horn diagonally 

 truncate towards the anterior part, the outside part left being 

 produced into a hamate process ; in the female the clypeus is sub- 

 parallel with the median part slightly diagonally produced beyond 

 the outer angles and truncate, the anterior margin being slightly 

 raised ; antennal club slightly larger than the pedicel in the $ , 

 equal in length in the $ ; prothorax ampliated laterally from the 

 apex to the base, but not very diagonal in the anterior part, and 

 only slightly sinuate in the posterior, base very little arcuate laterally 

 as well as above the scutellum which is sharply elongate ; elytra 

 elongate, attenuate behind, half the width of the base at apex ; 

 slightly sinuate on the sides, but with the lateral process visibly 

 exposed ; pygidium slightly slanting ; prosternal process not pro- 

 jecting much, bluntly and broadly triangular at tip ; anterior femora 

 and tibiae of $ densely pubescent inwardly and very faintly tri- 

 dentate outwardly, the rudiments of teeth, including the apical ones, 

 far apart ; apical joint of fore tarsi densely pubescent underneath ;
