the length, dorsal intervals smooth, the four lateral ones very finely 

 aciculate. Length 9-9|- mm. ; width 3 mm. 



Hah. Cape Colony (Cape Town), Natal, teste De Chaud. 



In the same section with short frontal sulci, not arcuate behind, 

 De Chaudoir includes two species unknown to me, two of which are 

 apparently closely connected with A. chalceus. 



Abacetus stkiatus, Chaud.,''- 

 Bull. Mosc, 1869, p. 393. 



Bronze with an olive tinge, shiny on the upper part, almost black 

 underneath ; labrum dark, with a ferruginous edging ; palpi, first 

 joint of antennae and legs light ferruginous, the second and thhd 

 joints of antennae piceous red ; head smooth, frontal sulci very short 

 and not deep ; antennae slender, reaching further than the shoulders ; 

 prothorax broader than long, with the four angles much rounded, 

 moderately rounded laterally, discoidal part moderately convex in 

 the anterior part, almost smooth and without any transverse im- 

 pressions, median longitudinal groove very narrow but deeper near 

 the base, lateral grooves reaching short of the median part of the 

 disk, basal part with a few punctures between the lateral grooves ; 

 elytra a little wider than the prothorax, twice as long as broad, 

 moderately parallel, base subtruncate, humeral angles not sharp, 

 sinuate and acuminate apically, moderately convex on the upper 

 part, striae not deep but very distinct, intervals moderately plane, 

 very finely shagreened, the puncture on the third interval placed 

 towards the median part against the second stria, the series of 

 punctures on the eighth stria interrupted towards the median part. 

 Length 12 mm. 



Hah. ? Cape of Good Hope. 



Abacetus tibiellus, Chaud., 

 Log cit., p. 395. 



Colour nearly similar to that of chalceus , hut darker and more 

 shiny bronze. Is also much smaller ; head a little longer and 

 very smooth ; prothorax narrower, which gives it the appearance of 

 being more elongated, anterior angles projecting more, the basal 

 ones more marked and straighter, discoidal part quite smooth 

 except for a few punctures on the edge of the base, the recurved 

 outer margin is a little narrower ; elytra altogether similar in shape, 

 striae narrower, intervals hardly perceptibly shagreened. Length 

 6 mm. 



Hah. Cape of Good Hope. 



* I am inclined to believe that A. cai^cnsis and this species are synonymous.
