South African Coleopterous Fauna. 191 



reaching the anterior setigerous pore ; prothorax as broad as 

 long, arcuate laterally from apex to base, but broader in the 

 anterior than in the posterior part where it is not sinuate, but 

 the basal angle is sharp, and projects, the oiiter margin is reflexed, 

 the lateral sulcus is narrow and reaches from the anterior angle 

 to the basal pore and is not continued along the basal margin to the 

 basal longitudinal sulcus, the space along the base between the sulci 

 and the median longitudinal line is impunctate, the anterior part of 

 the disk which is broadest across the median part is slightly convex 

 and the sides of the posterior are not depressed or reflexed laterally; 

 elytra oblong, narrower than the base of the prothorax but with the 

 humeral part slanting, the impunctate striae are deep and the inter- 

 vals plane, the puncture on the third interval is about median ; the 

 under side is smooth ; the episterna only slightly longer than broad, 

 the last abdominal segment has four setigerous punctures ( ? ) ; the 

 hind tibiae are tri-sulcate, and so are the hind and intermediate tarsi. 



Not unlike some species of Mclauodcs. 



Length 9 mm. ; width 4 mm. 



My previous description of this species was somewhat faulty. 



ABACETUS DIVERSUS, n. sp. 



Black, very shiny, the two basal antennal joints, the palpi, the 

 extreme edge of the lateral marginal fold and the legs more or less 

 deeply piceous-red ; frontal impressions somewhat slender, arcuate ; 

 prothorax longer than broad, moderately attenuated laterally from 

 the anterior setigerous puncture to the sharp anterior angle, sub- 

 parallel from the setigerous puncture to the outer basal angle, yet 

 slightly sinuate at about two-thirds of the length, the posterior angle 

 is sharp but does not project, the marginal fold is reflexed, the 

 sulcus is not deep and disappears almost in the posterior part at 

 about two-thirds of the length, then starts again near the posterior 

 setigerous puncture and runs along the straight base, which is wider 

 than the apex, as far as the somewhat long, narrow, slightly arcuate 

 basal sulci, the space between them and the median longitudinal 

 impressed line is impunctate, and the sides of the hind part is plane; 

 it is very little convex in front, and its greatest width is across the 

 middle, which is, however, hardly wider than the base ; elytra 

 oblong, hardly sloping behind the sharp humeral angle, the impunc- 

 tate striae are deep, and the intervals quite plane ; the puncture on 

 the third interval is situated slightly past the median part ; they are 

 slightly narrower at the base than the prothorax at its widest part ;
