Coleoiitera from South Africa. 171 



A. segnis, n. sp. 



Black, with a very slight greyish-brown coating ; head punctu- 

 late, with two small median impressions ; prothorax broadly ampli- 

 ated in the median part, sinuate behind, somewhat depressed on the 

 disk, with the outer sides flattened, closely but not deeply punctured 

 anGl with two very faint, rounded, discoidal supra-basal impres- 

 sions ; elytra parallel, plane, slightly wider at the base than the 

 posterior part of the prothorax, costate, costse not much raised* 

 and intervals narrow, both strise and intervals densely granulosa ; 

 legs moderately slender ; anterior tibiaj of the $ a little curved,, 

 bi-dentate outwardly, apical part dilated inwardly, grooved and 

 with a broad, sharp carina underneath, intermediate tibia3 slightly 

 sinuated outwardly towards the apex. Length 22, width 11 mm. 



Hah. Zambezia (Manica). 



Allied to A. plaiuis, Yahr., and A. affinis, Per.; but the 

 anterior tibiae end differently^ and have not the con- 

 spicuous apical inner spine directed downward ; the 

 costfe on the elytra are very well defined and regular.

 Gen. BYZA.CNUS, Pasc. 



B. capensls, u. sp. 



Head, prothorax and legs piceous-brown, median part of the pro- 

 thorax with a sub-metallic sheen, elytra dai'k metallic-green ; head 

 very closely punctured, antennte short, reaching only the median 

 part of the prothorax, which is much depressed, as long as broad, 

 sinuate and a little narrowed behind, closely foveate, with the 

 foveas small ; elytra not broader at the base than the posterior part 

 of the prothorax, gradually ampliated laterally in a triangular 

 shape from the base to two-thirds of the length, and from thence 

 abruptly truncate, while the disk is also gradually raised, although 

 plane, from the base to the top of the declivity, which like the 

 discoidal and lateral parts are roughly foveate ; tibite curved ; 

 underside punctulate. Length 11-13, width 6-7 mm. 



Kah. Cape Colony (Port St. John). 



Easily distinguished from its congener B. incticollis, 

 Pasc, by the absence of tubercles on the declivous part 

 of the elytra.
