Agenius suturalis, Waterh., 



Ann. and Mag. Nat. Hist. (5), xv., 1885, p. 379. 



namaquensis, Pering., Trans. S. Afr. Phil. Soc, iii., 1885, p. 100. 



Male: Black, with the elytra light straw-colour, and having a 

 somewhat broad outer marginal black band and a sutural one reach- 

 ing from the base to the apex ; clypeus, head, and prothorax shaped 

 and sculptured as in A. davits, but the latter is covered with a 

 moderately dense, long, greyish pubescence ; the elytra, which are 

 shaped like those of the preceding species, are more distinctly punc- 

 tate, and the intermediate tibiae are also strongly curved inwardly ; 

 the pygidium and under side are clothed with a very dense greyish 

 pubescence. 



Female : Similar in shape and sculpture to the same sex of A. 

 clavus, but the elytra instead of being entirely black are brick-red, 

 with a very broad sutural band reaching from base to apex, and 

 have a similarly broad outer marginal one ; these two bands coalesce 

 occasionally, leaving only the basal part red; the under side is 

 glabrous. 



Length 13J- 16f mm. ; width 6J-8 mm. 



Hab. Cape Colony (Namaqualand). 



Agenius rufipennis, Gory and Perch., 

 Mon. Cet., p. 96, pi. 11, fig. 5. 



Male : Black, with the elytra brick-red, very little shining, 

 glabrous ; antennae rufo-flavescent with the exception of the basal 

 joint which is black ; clypeus with the margins thickly refiexed, 

 slightly arcuate in front, not much constricted laterally, and, like the 

 head, which is a little longer, thickly punctate ; prothorax ampliated 

 laterally in the centre, and equally narrowed towards the apex as 

 towards the base which is plainly bi-sinuate with the angles not 

 sharp but not rounded, the disk is covered with round, equi-distant 

 punctures ; scutellum sparsely punctate ; elytra plane, slightly 

 broader across the middle than across the base or the apex, not 

 striate but having rows of serrate punctures especially distinct in 

 the median dorsal part, they are brick-red, and along the suture runs 

 a narrow black band reaching from the base to the apex and some- 

 what dilated in the centre, the outer marginal fold is black ; pygidium 

 concolorous ; intermediate tibiae not arcuate. 



I have seen two males only of this seemingly rare species ; they 

 have no white markings, nor traces of them, and they are not shiny,
