Plagiochilus corniger, Westw., 

 Thesaur. Entomol., p. 42, pi. xii., fig. 4. 



" Small, narrow ; head with a raised tubercle between the eyes ; 

 prothorax sub-oval, and having in the centre a large, oval impres- 

 sion : elytra elongated, sub-parallel ; antennas rufo-piceous. The 

 head is rather short, the clypeus broad with the fore margin slightly 

 emarginate in the middle; the prothorax is broader than the head, 

 the sides rounded, the greatest width being about the middle of 

 its length, the anterior angles are not prominent, but the posterior 

 ones are acute ; the elytra are very narrow ; the head is punctured 

 rather strongly and closely, as is the front of the promotum, with 

 the punctures circular, but behind the middle the punctures are 

 more linear, and so arranged as to form two oval circles. The 

 elytra are punctured, the punctures emitting luteous setae, those 

 on the basal half of the elytra being sometimes more or less con- 

 fluent, forming two or three ill-defined abbreviated striae in addition 

 to the two decided striae on each side of the suture. The anterior 

 tibiae are broad and bi-dentate, the tarsi flattened, with the joints 

 dilated ; the abdomen is convex beneath ; the under side is black 

 and glossy, punctured and setigerous, as are the top and under sides 

 of the prothorax." 



Length 7^ mm. 



Hab. South Africa. 



This species is allied to C. setosus, and the shape of the ligular 

 part is identical.

Black, covered on the upper and under sides with a very long, 

 sub-lanuginose, erect, flavescent pubescence; antennal club testa- 

 ceous ; ligular part flat outwardly, sinuate in front ; clypeus sinuate 

 in front but with the margin not reflexed, and foveate like the head, 

 the pubescence is erect and very dense ; prothorax covered with 

 confluent, oval, cicatricose punctures with a double ring, every one 

 of which is setigerous ; discoidal part without impression ; scutellum 

 with similar but more elongated punctures ; m elytra elongated, very 

 deeply sinuated laterally, sub-obliquely impressed below the humeral 

 callus, but not costate, on each side of the suture which is raised 

 in the hind part only are two geminate striae, the remainder of the 

 surface is covered by sub-reticulate, elongated setigerous punctures ; 

 pygidium strongly strigillate longitudinally, convex, with the convex
