Show 1904.] OF THE GENUS HIPPORRHINUS. 77 with sparse pale seta?; posterior tarsi with the joints of same width, 2nd and 3rd subequal in length, 1st rather longer. C A P E COLONY : Table Mt. T Y P E in the Stockholm Museum. 63. fH. KNYSNA, sp. nov. Long. 28, lat. 11 m m. Head convex, closely shagreened, and with bx-own scaling on vertex ; foi-ehead with a shallow central stria, dispersely punctured and with scattered white scales; anteocular furrows distinct, not convex-gent above. Rostrum not incised at base, as long as head and prothorax, strongly curved and dilated from behind middle to apex. Upper sux-face dispersely punctured laterally, and witli scattered isolated white scales, plane or slightly convex at base, deeply and broadly excavate anteriorly, tlxe edges there being sharply carinate; lateral sulci shallow, tlxe upper pair much shorter than tlxe lower and uniting at base; scrobes deep, directed beneath base of rostrum ; inferior basal fux*row absent. Antenna' with dense black and white seta?; scape scarcely reaching eye; the two basal joints of funicle subequal. Prothorax almost as long as broad, apex rather narrower than base, sides slightly rounded, broadest rather behind middle, dox-sal antex-iox- margin convex, but emai-ginate 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 depi-essecl tubercles on each side of it; beyond this a broad smooth space, followed by two ox- three irregular lateral rows of rounded and elevated tubercles ; tubercles bare, shiny, each with a depressed dax-k seta, tlxe interstices with dense lax-ge round white scaling. Elytra elongato-ovate, shouldei-s sloping, sides not much rounded, broadest about middle, apical processes in $ stout, sharply conical and turned slightly upwards. Upper surface convex, with fairly regular rows of small gx-anules ; 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 smaller, more closely-set, conical tubercles; 4 and 6 with incomplete or interrupted rows; tubercles bare, shiny, each with a depressed dark seta, the interspaces with scattered large white scales. Legs with sparse white scaling and black seta?; posterior tarsi broad, the joints of the same width, 2nd and 3rd subequal in length 1st rather longer. C A P E COLONY : Knysna [S. A. Mus.]. T Y P E in the South African Museum. Very similar in general appearance to some examples of //. insignis Fahr., but readily distinguishable owing to its vexy different rostrum, which is much shorter and more strongly curved, its dorsal margins sharply carinate and the upper lateral sulci uniting at the base. |
