This species is not unlike A. natalcnsis, but differs by the colour of 

 the legs, and the wider prothorax which is also less cordiform. In 

 A. natalcnsis the hind tibiae are plainly grooved inwardly. 



Length 7 mm. ; width 3 mm.

ABACETUS CLAKUS, n. sp. 



Black, very shiny, slightly iridescent ; palpi and legs reddish, 

 antennae rufescent with the three basal joints plainly reddish ; frontal 

 impressions narrow, but deep and arcuate ; prothorax as broad at its 

 widest part as long, arcuatfily ampliated laterally from the anterior 

 angle to two-thirds of the length, attenuated obliquely thence to the 

 sharp, very little projecting basal angle which is covered by the 

 setigerous pore, the outer margin is sharp and slightly reflexed, the 

 sulcus is very plain, and of equal width from the apex to close to 

 the hind pore, and is not continued along the base only as a very 

 faint impressed line, the basal sulci are normal and set nearer to the 

 outer margin than to the median longitudinal line, and the space 

 between the two is clearly impunctate, the anterior part of the disk 

 which is at its widest in front of the median part is slightly convex 

 and the sides of the posterior are neither depressed nor reflexed ; 

 elytra oblong with the humeral part very little sloping, as broad 

 slightly below the shoulders as the prothorax at its widest part, the 

 impunctate striae are well defined, the intervals are slightly raised, 

 and the puncture on the third interval is nearly median ; last 

 abdominal segment with the normal four setigerous punctures ( ? ) ; 

 hind tibiae not grooved inwardly, posterior tarsi with the three basal 

 joints grooved outwardly ; apical joint finely setulose underneath ; 

 metasternal episterna nearly one-third longer than the anterior edge. 



This species is very closely allied to A. severini, Tsch., a species 

 from the Congo Free State (Boma), of which I have two types and 

 in which the hind tarsi have the three basal joints grooved outwardly, 

 but the posterior part of the prothorax is more constricted laterally 

 and therefore more cordiform, and the episterna are slightly longer. 



Length 7i mm. ; width 3 mm.

ABACETUS VEKTAGUS, n. sp. 



Black w r ith the elytra iridescent, the palpi, the three basal joints 

 of antennae and also the basal part of the fourth are rufo-flavescent,
