34 MR. G. A. K. MARSHALL ON COLEOPTERA [Jan. 19, 



Namaqualand : O'okiep {L. Peringuey). 



Type in British Museum. 



My original description was made from a single 5 taken by 

 Sir A. Smith ; Mr. Peringuey has since shown me at Capetown 

 a series of both sexes, which has enabled me to redescribe the 

 species more accurately. 



15. H. NAMAQUUS, sp. nov. 



Long. 18, lat. 8 mm. 



Mead convex, bare, deeply and coarsely punctured, forehead 

 with two deep longitudinal impressions ; anteocular furrows 

 present, but not very distinct. RostriLm separated from head by 

 a transverse dorsal incision, as long as head and prothorax, slightly 

 curved, sides subparallel throughout, but with the gense dilated. 

 Upper surface rugosely punctured, with a shallow central furrow, 

 containing no carina, and two narrow undulating carinse on each 

 side of it ; lateral sulci deep, of equal length, the ujDper pair 

 uniting at base ; scrobes deep, lateral and subparallel with the 

 sulci ; inferior basal furrow broad and deep. Antennce with scape 

 jiist reaching eye ; the two basal joints of funicle subequal. Pro- 

 thorax transverse, apex narrower than base, sides distinctly 

 rounded, broadest about middle, dorsal anterior margin truncate, 

 ocular lobes moderately developed. Upper surface convex, closely 

 set with small rou.nded tubercles, leaving a very narrow and 

 indistinct central furrow containing no carina ; tubercles bare, 

 each with a very short dark seta, the interstices with sparse large 

 round white scales. Elytra ovate, shoulders angularly prominent, 

 sides rounded, broadest rather behind middle, apical processes 

 obsolescent in S . Upper surface convex, without distinct 

 sulcation, there being on each elytron between the suture and 

 the summit of the infiexed margin fourteen even and regular rows 

 of small, closely-set, rounded tubercles, which are shiny and bear 

 very short depressed setee ; the interstices with a few scattered 

 large round white scales. Legs thick, coarsely punctured, with 

 long black setae and a few larger white scales ; tibiae very strongly 

 denticulate along their interior edges ; posterior tarsi broad, the 

 three basal joints subequal in length and breadth. 



Namaqualand : O'oldep {L. Peringuey). 



Type in my collection. 



The example upon which this species is founded was sent to me 

 some years ago by Mr. Peringuey under the name of alhicinctus 

 Gyl. It is, however, abundantly distinct from that species, as an 

 examination of the descriptions will show, though there is a 

 superficial resemblance in general facies. From its much nearer 

 ally congestus Mshl. it differs in the narrower and undulating rostral 

 carinse ; in the double impression on the forehead ; in the more 

 rounded shape of both prothorax and elj^tra ; in the complete 

 absence of the prominence on the third interval of the latter ; and 

 in the much greater thickness of the leg's.
