intervals quite plane and the third one bears no puncture ; under 

 side and tarsi as in the two preceding species. 



Length 64- mm. ; width 2^ mm. 



Hab. Transvaal (Pietersburg). Eev. H. A. Junod. 



ABACETUS INOPINUS, n. sp. 



Black, shiny, slightly iridescent, antennae and legs rafescent, 

 posterior part of elytra also rufescent ; frontal sulci not deep, 

 arcuate ; prothorax as broad as long, gradually arcuate laterally 

 from the slightly rounded anterior angle to two-thirds of the length, 

 obliquely narrowed thence to the sharp, projecting posterior angle, 

 the lateral sulcus abuts almost on to the basal one which is set close 

 to the outer angle, and the basal space between the two sulci is 

 deeply punctate, the sides of the posterior part are not depressed ; 

 elytra oblong with the humeral part rounded, as wide at the shoulders 

 as the prothorax at its widest point, the impunctate striae are deep, 

 the intervals moderately raised, the puncture on the third interval is 

 slightly ante-median, and the posterior part of the convexity is 

 rufescent ; the hind tibiae are very weakly grooved, the hind tarsi 

 are not sulcate, the last joint is glabrous ; the under side is smooth 

 and the metasternal episterna longer than broad. 



Length 6 mm. ; width 2 mm.

ABACETUS EFFULGENS, n. sp. 



Light bronze, shiny on the upper part, bronze-black on the under- 

 side ; antennae black with the basal joint red and the two following 

 f uscous-red, femora fuscous-red, tibiae red ; frontal sulcus somewhat 

 long, oblique ; prothorax as broad as long, ampliated and rounded 

 laterally for two-thirds of the length, and slightly sub-obliquely 

 narrowed and sinuate in the posterior part the outer angle of which 

 is sharp and slightly projecting, the base itself is slightly wider than 

 the anterior margin, the lateral sulcus is deep and connected along 

 the base with the basal one which is set somewhat close to the 

 outer angle, the space between the two basal sulci is very closely 

 punctate ; elytra oblong, very little rounded at the shoulders, not 

 wider than the prothorax at its broadest point, the impunctate striae 

 are moderately deep, the intervals plane, the strong puncture on the 

 third interval is aboiit median, and there is a slight longitudinal 

 median impression on the two first intervals ; the under side is 

 impunctate, the metasternal episterna are longer than broad ; the
