This species resembles P. coesics, but it is distinguished by 

 the bluntly bi-tuberculate posterior part of the head, the finer and 

 more closely set punctuation of the prothorax, and the more carinate 

 costae of the elytra. 



Pleurophorus natalensis, n. spec. 



Size, colour, and shape of P. capicola ; the head, however, has no 

 lateral protuberance, the clypeus is not so broadly emarginate ; the 

 prothorax has no median sulcate longitudinal line, and is covered 

 with a very closely set, fine, but very distinct punctuation, there is 

 no supra-lateral transverse impression, and the elytra are much 

 more deeply striate ; the punctures on the striae are large and 

 impinge distinctly on the intervals which are hardly convex ; the 

 basal joint of the posterior tibiae is shorter than the apical spur 

 which is very long. 



Length 3-3f mm. ; width 1 mm.

Mandibles membranaceous, very much reduced; mentum quad- 

 rangular, not emarginate at tip ; ligula and labial palpi obliterated ; 

 maxillae very robust and set with very long, stiff, bristly hairs, inner 

 lobe invisible, upper lobe scooped inwardly, the upper side is 

 produced into two very long horizontal parallel spines, and the lower 

 part has three similar spines ; maxillary palpi of Bhyssemus, but 

 with the apical joint very sharply acuminate ; clypeus rounded at 

 tip, margins slightly reflexed, under side of margin with a series of 

 deep foveate punctures bearing each a stiff seta ; genae hardly 

 distinct ; eyes somewhat large ; antennae with a robust, densely 

 ciliate club; prothorax very gibbose, constricted laterally and 

 diagonally grooved towards the base which is deeply excavate 

 on each side ; scutellum very much raised and hooked downwards ;. 

 elytra gibbose in the posterior part, oblongo-ovate, barely covering 

 the pygidium, humeral angles blunt ; the abdomen is very convex, 

 and the segments are apparently fused ; the intermediate coxae are 

 not very oblique, and are separated by a moderately broad interval^ 

 metasternum not grooved ; anterior femora armed with a strong, 

 basal spine, anterior tibiae very obliquely truncate outwardly, the
