base, and a semicircular, very deep impression on each side ; elytra 

 with very short and not dense pubescence, much broader than the 

 prothorax, the humeral angles slightly sloping, nearly plane in 

 the anterior part, obliquely dehiscent behind, carinate laterally 

 from the base to the median part, outer margin also carinate 

 from base to apex, the dorsal part with three lateral, undulating, 

 indistinctly defined cost« ; underside nearly glabrous ; legs 

 rugose, tomentose. Length 13, width 9 mm.

Allied to A. undatus, Haag-Rutenb. The elytra are a 

 little less sloping at the humeral part, a little more plane 

 on the disk, and with less undulating costas; the legs 

 are also more slender. 



A. costatus, n. sp. 



Black, covered with a brown tomentum ; head rugose ; prothorax 

 gibbose, much compressed on each side of the median discoidal part ; 

 elytra nearly truncate at the base, subquadrate for two-thirds of 

 their length, dehiscent behind, plane, and with one lateral and two 

 very sharp discoidal costaj, the lateral costa ending in a sharp point 

 at the top of the posterior declivity ; underside nearly glabrous ; 

 legs with very short pubescence. Length 10-14, width G-8 mm.

 and Zambeze Rivers).

A. (Acmaius) jpodagriciLS, n. sp. 

 Black, opaque, more or less densely covered with a brownish 

 coating ; head with broad, close punctures, labrum and epistoma 

 deeply incised ; prothorax very much ampliated in the anterior 

 part, narrowed and sinuated from the median part to the basal 

 angle, which is sharp and slightly projecting backwards ; the pos- 

 terior part of the prothorax is narrower in the $ than in the $ , 

 convex, with the outer sides a little depressed, with very closely- 

 set, equal punctures, and having two round impressions on each 

 side of the disk ; elytra nearly parallel, not much broader than the 

 base of the prothorax, more convex in the $ than in the $ , in 

 which sex they are moderately plane in the anterior part, convex and 

 deflexed behind, finely gran ulose and with three raised lines on each 

 side, and occasionally a faint trace of intervening lines ; legs very
