margin is sharp and slightly reflexed, the lateral sulcus wide and 

 reaches from the apex, the angle of which is sharp but not pro- 

 jecting, to the somewhat indistinct hind pore, and is connected 

 along the margin by a narrow line with the basal sulcus, which 

 is situated slightly nearer to the outer margin than to the median 

 longitudinal line, the interval between the basal sulcus and the 

 median line is impunctate, and the sides of the posterior part 

 of the disk are not depressed ; elytra oblong, slightly wider than the 

 base of the pro thorax, and as broad slightly past the humeral part 

 as the widest point of the prothorax, striae impunctate, deep, 

 intervals convex, the puncture on the third interval median ; last 

 abdominal segment with two or four setigerous punctures according 

 to the sex ; metasternal episterna much longer than the anterior 

 edge ; hind tarsi pluri-sulcate. 



Allied to A. pavoninus, but smaller, and the prothorax is less 

 ampliated laterally. 



Length 8-9 mm. ; width 3i-3f mm. 



Hab. Southern Ehodesia (Umtali). A. Bodong. 



ABACETUS MIMUS, n. sp. 



The description of A. diliicidus suits the present species, except 

 that the sides of the prothorax are depressed in the basal part 

 between the basal sulcus and the outer angle, which is sharp, but 

 does not project, the basal sulcus is equi-distant from the outer 

 margin and from the median longitudinal line, and the space 

 between the two is finely and very closely punctulate ( J ), the 

 prothorax is also slightly wider at the base. 



Length 8 mm. ; width 3-J- mm.

ABACETUS JUCUNDULUS, n. sp. 



Intermediate in shape and in the sculpture of the prothorax 

 between A. diliicidus and A. mimus; from the former it differs 

 by the colour, which is plainly iridescent, especially the elytra, the 

 shape of the prothorax is the same, but the space between the 

 median longitudinal line and the basal sulcus is sparsely punctulate, 

 the punctures being denser along the sulcus, whereas in .-1. diliicidus 

 this space is plainly impunctate ; from A. mimus it differs in the 

 prothorax being slightly narrower towards the base, and in the basal 

 space between the longitudinal line and the basal sulcus being
