minute, somewhat scattered, fulvous hairs ; prothorax convex, as 

 broad as long, slightly attenuate rounded in the anterior part for 

 about one-third of the length, nearly but not quite parallel thence 

 to the outer basal angle which is not rounded, but is not sharp, the 

 base is strongly bi-sinuate, and the surface is covered with con- 

 tiguous, scabrose punctures divided by a very thin, sharp wall, which 

 gives them a shagreened appearance ; from these punctures spring 

 sparse, minute, fulvous hairs, but the outer margin is fringed with 

 moderately long fulvous hairs ; in the female there is a median, 

 anterior smooth line, occasionally obliterated ; elytra ampliated 

 behind from about the median part, slightly sinuate laterally, convex 

 in the posterior part, and covered with scabrose, contiguous punc- 

 tures, bearing each a minute, fulvous hair ; they are slightly striate, 

 the suture is raised, and there are on each side two costules in the 

 discoidal part ; pygidium and under side closely punctate and 

 clothed, like the legs, with a long, fulvous pubescence ; upper spur 

 of hind tibise slightly compressed and rounded at apex in both sexes. 



Length 12^—13 mm. ; width 7-7| mm. 



Hab. Southern Ehodesia (Salisbury, Enkeldoorn, Umtali). De- 

 scribed originally from German East Africa. 



DIPLOEIDA, n. gen. 



Mentum quadrate, with the ligular part conspicuously attenuate 

 laterally, and divided at apex into two lobes by a deep, broadly 

 triangular incision, labial palpi inserted almost on the outer face of 

 the lobate part, last joint sub-fusiform outwardly, maxillae somewhat 

 robust, upper lobe somewhat elongate, simple, surmounted by a 

 lateral fascicle of hairs ; clypeus diagonally narrowed laterally, 

 triangularly incised at apex, a little longer than the head ; eyes 

 moderately large, the canthus dipping and very hairy ; prothorax 

 slightly longer than broad, narrower at the apex than at the base 

 with the hind angles rounded, strongly sinuate along the base, 

 somewhat convex in the posterior part ; scutellum cordiform, nearly 

 as broad as long ; elytra with the humeral callus strongly developed 

 and almost overhanging the outer margin, which is only slightly 

 sinuate, and covers the metathoracic epirnera ; mesothoracic epimera 

 vertical, hardly visible when looked at from above ; legs robust ; 

 anterior tibiae tri-dentate, the intermediate and posterior dilated at 

 apex, plainly toothed on the upper margin, tarsi moderately short ; 

 metasternum moderately broad, the epimera not bulging, meso- 

 sternum scooped out. 



Allied to Diploa, but apart from the shape of the clypeus, which is 

 very different, it is differentiated by the upper maxillaiy lobe, which
