the apical angle which is slightly rounded, outer part of the lobes 

 very little ampliated in the centre ; last joint of maxillary palpi sub- 

 fusiform, blunted at the tip, the penultimate one of the labial twice 

 as long as the last one, both much more slender than the maxillary; 

 maxillae much curved outwardly, apical part hamate, but not sharp 

 at tip, very thickly fringed outwardly with thick long incuivate 

 bristles ; labrum very short, the median part triangular ; head short, 

 twice as broad as long, the superciliary ridge produced in a very 

 acute carina in front of the eye ; genae (cheeks) indistinct ; antennae 

 reaching slightly beyond the median part of the prothorax, the basal 

 joint, subclaviform, is nearly as long as the three following ones, the 

 second nearly as long as the third and fourth together, the others 

 are moniliform ; prothorax nearly twice as broad as long, truncate 

 in the apex, with the lateral angles projecting, hardly rounded 

 laterally with the posterior angle very distinct, lateral sides of the 

 base slightly oblique, median part slightly produced backwards ; 

 elytra short, twice the length of the prothorax, not so broad at the 

 base, with the humeral angles acutely toothed, gradually ampliated 

 to past the median part ; tarsi short, the three digits of the anterior 

 tibiae extremely long, the first two curving outwardly, the two inner 

 teeth also very long, intermediate and posterior ones much

Black, shining ; head very deeply impressed on each side, the 



impressions nearly reaching the base, and deeply plicate ; antennae 



and palpi rufescent, a triangular process in front of the eyes ; 



prothorax plicate longitudinally from the apex to the transverse line, 



the disk transversely plicate with the plicaB wavy, basal part smooth, 



shining with a deep lateral impression ; elytra striate, the intervals 



subrugose, much raised, convex, almost carinate behind, setigerous 



punctures absent, no intra-marginal carina, but the space between 



the eighth interval and the outer margin broad and very rugose ; 



abdominal segments subplicate longitudinally, the ultimate one 



rugulose, metasternum slightly shagreened ; posterior tibiae curving 



outwardly. Length 18-23 mm. ; width 6^8 mm. 



This species, one of the most distinct South African form, has no 

 ally. It is found in plenty on the seashore, under the masses 

 of the decaying seaweeds, Sargassum longifoUiun, and S. ijitcgrifolium, 

 and Echlonia huccinalis, the " sea bamboo " of the colonists.
