1897.] PHYfOfHAGOUS COLEOtTERA. OF AFEIOA. 265 



thorax with a central sulcate elevation, finely rugose ; elytra with 

 eight or nine strong tubercles, the disc with a fulvous or flavous 

 oblique ridge, the interstices finely rugosely punctured ; pygidium 

 foveolate-punctate. 



Length 1 line. 



Of posteriorly slightly narrowed shape, varying in colour from 

 fulvous mixed with piceous or nearly entirely of the latter colour, 

 but the raised tubercles generally of paler coloration ; the head 

 entirely finely rugose or closely covered with round punctures, 

 which are more or less of whitish corrugated appearance at 

 the vertex ; eyes transversely and narrowly notched ; antennae 

 very short, fulvous, the second and following joints very short, 

 the terminal five transversely shaped ; thorax with the middle 

 portion raised into a high bump, the centre of which is longitudi- 

 nally sulcate, from this elevation three or four oblique ridges run 

 downwards at the sides towards the margin, all the interspaces 

 between these ridges are closely rugose like the head, and assume 

 the same whitish appearance at the sides and in front of the 

 elevation, the other portions remaining partly nearly black or 

 fulvous, the lateral margins are nearly straight, the basal one is 

 deeply sinuate at the sides ; scutellum strongly transverse ; elyti-a 

 sculptured like the thorax ; with a strongly raised oblique ridge of 

 flavous or fulvous colour at the middle of the disc, at the com- 

 mencement and at the apex of this ridge, two or three tubercles, 

 placed obliquely, ai*e situated, which are partly joined ; of the other 

 tubercles, a very highly raised one is placed at the base, one near 

 the suture at the apex, and one near the lateral margin at the same 

 place, as well as one at the sides close to the ridge near the middle 

 of the elytra, the entire suture of the latter is finely serrate ; 

 underside and pygidium sculptured as the upper surface, the pj'gi- 

 dium with several deeper dark-coloured fovese ; legs fulvous, stained 

 with piceous ; tarsi entirely dark. 



Hah. Natal, Estcourt {G. Marshall). 



Three African species of Chlamii.i have up to the 'present been 

 described, from all of which C. natalensis differs in its coloration 

 and peculiar sculpturing ; in all specimens the curious whitish or 

 mouldy appearance of part of the thorax and other portions is 

 present, although variable like the coloration.
