Show 1904.] OF THE GENUS HIPPORRHINUS. 49 with a deep central furrow, which is narrow in the middle, dilated towards apex, and still more so basally, where it merges into the excavation of the forehead ; scaling dense, fulvous, and with conspicuous large scattered punctures; upper lateral sulci absent, lower pair shallow ; scrobes directed beneath base of rostrum ; infexior basal furrow present. Antenna} short, scape scarcely reaching eye ; the two basal joints of funicle subequal. Prothorax scarcely longer than the width at base, apex narrower, sides dilated before middle into a strong recurved spine, anterior margin convex, ocular- lobes moderate. Upper surface somewhat convex, with a deep cexxtx-al furrow, bordered by a tubercular costa in its anterior half axxd containing a strong smooth carina ; the lateral portions are rather sparsely set with small rounded tubercles; costa? and tubercles bare, the interstices with dense fulvous scaling. Elytra ovate, broadest about middle, shoulders roundedly prominent, apical processes ixx $ long, stout and sharp. Upper surface convex, irregularly arid transversely subreticulate, the intervals 3, 5, and 7 more raised than the others, subcostate, but more or less distinctly tuberculate towards apex ; the remaining intervals with interrupted and incomplete rows of depressed tubercles. Tubercles bax-e and shiny, tlxe interspaces densely covered with small fulvous scales. Legs variegated with pale scaling ; posterior tax-si broad, spongy beneath, the joints of the same width, 2nd and 3rd of equal length, 1st x-ather longer. TRANSVAAL : Rustexxburg.

Head convex, with close shallow punctuation and fulvous scaling, forehead without fovea or carina; anteocular furrows deep, subcorxvergent above. Rostrum not incised at base, as long as head and prothorax, stx-ongly cuxwed and dilated from middle to apex. Upper surface with a deep central furrow thx-oughout, dilated anteriorly and containing a distinct rounded impression at base ; tlxe furrow impunctate, but the adjoining costa? coarsely punctured axxd with scattered large white scales; upper lateral sulcus absent, the lower one deep and distinct; scrobes deep, directed beneath base of rostrum; inferior basal furrow present. Antennce with scape not nearly reaching eye ; tlxe two basal joints of funicle subequal. Prothorax transverse, tlxe length equal to width at base, apex narrower, sides ampliated and armed about middle with a sharp tubercular spine, dorsal anterior margin convex, ocular lobes moderate. Upper surface somewhat convex, with a tubercular callus along apex, sparsely set with large rounded tubercles, leaving a broad central furrow containing a short low ' PROC. ZOOL. Soc-1904, V O L . I.
