Upper surface convex, with regular rows of small granules; interval 1 with a row of .small low tubercles, decreasing greatly in size towards apex; intervals 2, 3, 5, and 7 with complete rows of large, depressed, elongate and separated tubercles, which become bluntly conical near apex, those on the declivity of interval 2 being larger than the rest; intervals 4 and 6 smooth, or at most with a few isolated tubercles near base; tubercles bare, with short black depressed seta?, interstices (except on intervals 2 and 3) clothed with dense or cTeam-coloured scaling. Legs with dense yellowish scaling variegated with bare black spots; posteriox* tarsi with joints of about the same width, 2nd axxd 3rd subequal in length, 1st rather longer. CAPE COLONY ; DAMARALAND. 58. H. MACULATUS Mshl. (Plate II. fig. 9.) //. maculatus Mshl. 1. c. p. 412 (1902). Long. 26, lat. 11 mm. Head convex, closely shagx-eened on vertex, puxxctured in front* with a broad band of elongate yellow scaling across forehead and running down in front of each eye; forehead with a deep fovea neax- base of rostrum; anteocular furrows deep and complete, coix-verging somewhat dorsally. Rostrum not incised at base, as long as head axxd prothox-ax, in px-ofile tlxe upper line is straight fx'onx base to near the insertion of the antenna?, then sharply deflected. Upper surface broadly but very shallowly excavate throughout, with its edges strongly carinate from base to insertion of antenxxa?, with punctures and yellow scaling at the sides, and a broad smooth central line throughout ; upper lateral sulci obsolete, the lower ones faixxt, filled with yellow scales, and quite hidden from above by the lateral carina ; scrobes directed beneath base of rostnxm ; inferior transverse basal furrow absexxt. Antennas with dense yellow scaling; scape not quite reaching eye ; the two basal joints of funicle subequal. Prothorax transverse, length equal to width at base, apex narrower, sides strongly rounded, broadest about middle, ocular lobes moderately developed. Upper surface almost plane, sparsely covered with large flattened tubercles, leaving a central furrow containing a vexy short carina axxd a latex-al smooth lixxe on either side ; presternum and the three dorsal lines covered with yellow scaling, tlxe rest bare. Elytra ovate, shoulders sloping, sides moderately rounded, broadest about middle, apical processes ixx female long and sharp. Upper surface convex, the striae with mox-e or less regular rows of large granules, the intervals unequally tubei-culate; interval 1 with elongate depressed tubercles, becoming smaller behind and vanishing before apex; intervals 2, 3, and 5 with closely-set, elongate, depressed tubercles to beyond middle, after which they become sharply conical to apex, those on interval 2 being most prominent; intervals 4, 6. and 7 with smaller separated tubercles, depressed near base and conical towards apex; tubercles and granules quite bare and |
