furrow ; tubercles bare, each with a very short depressed dark 

 seta, the interstices with sparse white scahng. Elytra narrowly 

 ovate in 5 , much narrower and more oblong in S , shoulders 

 sloping, sides not much rounded, broadest before middle, a low 

 tuberculate intra-apical callus on each side, which is more promi- 

 nent in 2 • Upper surface convex, the sulci with regular rows 

 of distinct punctures ; the intervals all similar, each with a row of 

 large closely-set granules, which are shiny, each having usually a 

 very short dai-k depressed seta, the interspaces with scattered spots 

 of round whitish scales. Legs with sparse white scaling, forming 

 a denser ring near apex of femora ; anterior tibias distinctly 

 sinuate extei'nally in ^ , simply curved in 5 > posterior pair not 

 denticulate internally in either sex ; posterior tarsi with joints of 

 equal width, 2nd and 3rd subequal in length, 1st slightly longer. 



Namaqualaisid : O'okiep (Z. Peringuey). 



Type, S iii^ the British Museum, 5 in the South Afi-ican 

 Museum. 



Probably the Namaqualand representative of H. capensis L., 

 from which, however, it differs much in appearance, owing to its 

 large size and elongate shape ; the external sinuation in the 

 anterior tibise of the S is an unusual character.

Head very convex, punctuation faint, close on vertex but 

 diffuse in front ; f oi'ehead with a shallow central depression ; 

 eyes surrounded by a narrow impressed ring ; anteocular furrows 

 distinct. Rostrum cut off from head by a deep doi'sal incision, 

 thick and strongly cui'ved, as long as prothoi'ax only. Upper sur- 

 face with five smooth narrow carinse, the interspaces indistinctly 

 punctured and with short pale setae ; lateral sulci deep, the upper 

 and lower pairs of equal length, the former uniting at base ; 

 scrobes lateral, subparallel to the sulci ; infeiioi' basal furrow 

 very deep. Antennce piceous, finely pubescent ; the scape just 

 reaching eye ; the 1st joint of funicle longer than 2nd. Prothorax 

 distinctly transverse, base and apex of equal width, sides strongly 

 rounded, broadest about middle, dorsal anterior margin truncate, 

 ocular lobes feeble. Ujjper surface rather convex, closely set with 

 low rounded tubercles, leaving a narrow central fuiTOw without a 

 carina ; tubercles bare, each with a very shoi't pale depi'essed 

 seta ; interstices with dense yellowish scaling. Elytra oblongo- 

 ovate, shoulders roundedly prominent, sides scarcely rounded, 

 broadest about middle, apical processes absent. Upper surface 

 convex, with shallow sulci containing faint punctures separated 

 by intervening granules ; intervals all similar, bearing single rows 

 of depressed granules, each having a short pale seta ; the suture 

 strongly raised on the declivity only ; scaling fairly dense 

 variegated light brown and whitish. Legs with sparse pale setas
