part, striate with the intervals plane. Length 5-^-6 mm. ; width 

 2-2J mm. 



Allied to A. viarius, but it differs in colour and in the shape of the 

 prothorax, the posterior lateral part of which is straighter. 



Hab. Cape Colony (Uitenhage). 



Abacetus proximus. 



Black, shining ; antennae, palpi, and legs brownish red ; head smooth, 

 impressions moderately deep and short ; prothorax a little ampliated 

 and rounded laterally, narrowed for a short distance near the base 

 with the outer margins carinate but not recurved, and the posterior 

 angles sharp ; it is quite smooth on the disk ; the basal impressions 

 are long and deep, and the base is not punctulate ; elytra oblong, 

 shining, deeply striate with the intervals plane. Length 10 mm. ; 

 width 4 mm. 



Allied to A. crassicornis, Catal., p. 547, which it much resembles ; 

 it is differentiated by the colour of the legs and antennas, which in 

 A. crassicornis are black, the latter are much thicker and more com- 

 pressed, and also by the absence of punctures along the base. 



Hab. Cape Colony (Uitenhage). 



Abacetus pavoninus. 



Black, with the elytra iridescent ; antennae infuscate ; the two 

 basal joints, palpi, and legs piceous ; head smooth ; the tw T o 

 anterior impressions narrow, deep, arcuate ; prothorax gradually 

 rounded laterally from apex to base, nearly truncate at apex, sinuate 

 at base, broadest in the median part, very little wider at base than 

 at apex, smooth, the basal impressions long, narrow, and deep, 

 outer margins reflexed ; elytra oblongo- ovate, narrowly striate, striae 

 not punctured, intervals plane ; under side piceous-black. Length 

 10^ mm. ; width 4 mm. 



The specific characters consist in the rounded shape of the 

 prothorax, which is not at all constricted or attenuated laterally near 

 or above the posterior angle, which is also more blunt than usual ; 

 it is the only South African Abacetus known to me having iridescent 

 elytra. Should follow A. masluaius. 



'Hab. Natal (D'Urban ?). 



Abacetus diversus. 

 Dark bronze,' shining ; antennae black, the two basal joints red-
