63. tH. KNYSXA, sp. nov. 



Long. 28, lat. 11 mm. 



Head convex, closely shagreened, and with bi'own scaling on 

 vertex ; forehead with a shallow central stria, dispersely punctured 

 and with scattered white scales ; anteociilar furrows distinct, not 

 convei'gent above. Rostrimi not incised at base, as long as head 

 and prothoiax, strongly cui'ved and dilated from behind middle 

 to apex. Upper suiface dispersely punctured laterally, a,nd with 

 scattei'ed isolated white scales, plane or slightly convex at base, 

 deeply and broadly excavate anterioi-ly, the edges there being 

 sharply carinate ; lateral sulci shallow, the upper pair much 

 shorter than the lower and uniting at base ; scrobes deep, directed 

 beneath base of rostrum ; inferior basal furrow absent. Antennce 

 with dense black and white setje ; scape scarcely I'eaching eye ; 

 the two basal joints of funicle subequal. Prothorax almost as long 

 as broad, apex rather nai-i-ower than base, sides slightly rounded, 

 broadest rather behind middle, dorsal anterioi- mai-gin convex, but 

 emarginate in the middle, ocular lobes strongly developed. Upper 

 surface convex, with a broad but very shallow and ill-defined 

 central furrow containing a low carina and with a row of large 

 depressed tubercles on each side of it ; beyond this a broad smooth 

 space, follow^ed by two or three iwegular lateral rows of rounded 

 and elevated tubercles ; tubercles bare, shiny, each with a depressed 

 dark seta, the interstices with dense lai-ge round white scaling. 

 Elytra elongato- ovate, shouldeivs sloping, sides not much rounded, 

 broadest about middle, apical processes in 5 stout, sharply conical 

 and turned slightly upwards. Upper surface convex, with fairly 

 regular i-ows of small granules ; interval 1 with a row of tubercles, 

 becoming much smaller behind middle and vanishing before apex ; 

 intervals 2 and 3 with complete rows of large tubercles, which are 

 elongate and depressed on disk, but sharply conical and more 

 distant behind ; intervals 5 and 7 with complete rows of smallei", 

 more closely-set, conical tubercles ; 4 and 6 with incomplete or 

 inten-upted rows ; tubercles bare, shiny, each with a depressed 

 dark seta, the interspaces with scattered large white scales. Legs 

 with sparse white scaling and black setfe ; posterior tarsi broad, 

 the joints of the same width, 2nd and 3rd subequal in length 

 1st rather longer. 



Cape Colony : Knysna [S. A. Mus.]. 



Type in the South African Museum. 



Very similar in general appearance to some examples of 

 H. insignis FShr., but readily distinguishable owing to its very 

 different rostrum, which is much shorter and more strongly 

 curved, its dorsal margins sJiarply carinate and the upper lateral 

 sulci uniting at the base.
