I would have referred the present species to E. madagassus, 

 Har., had not the auterior femora been described in the diagnosis 

 by the author as strongly dentate, of which no sign is to be detected 

 in the two specimens before me ; the elytra are also said to be 

 deeply punctate-striate, while here they are A'ery finely so froui 

 the middle downwards. E. metallicus, Jac, is of more narrow, 

 parallel shape, the antennae are much longer, the thorax is much 

 less transversely shaped, and the elytra are deeply punctate-striate 

 throughout. 



EUETDEMUS HOIiUBI, U. Sp. 



Dark brown ; thorax extremely finely and sparingly punctured ; 

 elytra strongly punctate-striate, the interstices strongly longi- 

 tudinally costate ; femora with a distinct tooth. 



Length 2 lines. 



Head distinctly but not closely punctured, with a slight central 

 ridge ; the clypeus distinctly separated from the face, more strongly 

 punctured ; eyes large, the inter\ ening space narrower than their 

 diameter ; the antennae extending to the middle of the elytra, 

 fulvous, the second joint but little shorter than the third, the 

 following joints slender and elongate : thorax one-half broader 

 than long, narrowed in front, the sides rounded, the posterior 

 angles thickened, with a single seta, the surface with some very 

 fine punctures at the middle, the sides nearly impunctate ; elytra 

 much broader than the thorax, feebly transversely depressed below 

 the base, with deeply and closely punctured striae ; the interstices 

 strongly raised, forming highly raised cost^ near the apex and at 

 the sides : underside and legs coloured as above ; the femora with 

 a strong tooth. 



South Africa (Holub). 



Of this distinct species, principally distinguished by the costate 

 elytra, three specimens are contained in my collection without 

 particular locality, having been obtained by Herr Holub, the 

 African traveller. 



IVONGIUS MINtTTUS, n. Sp. 



Testaceous, the seventh and the apical two joints black ; thorax 

 transverse, sparingly punctured ; elytra strongly punctate-striate ; 

 femora unarmed. 



Length |-1 line. 



Head extremely finely punctured, rather convex, the eyes 

 surrounded by a narrow sulcus ; clypeus separated from the face 

 by a distinct transverse groove, nearly im punctate ; palpi and 

 antennae flavous, the latter extending beyond the middle of the 

 elytra, the basal and the second joint thickened, the latter as long 

 as the third joint, the seventh and the terminal two joints black,
