Show 1904.] OF THE GENUS HIPPORRHINUS. 121 " bifid at apex; forehead depressed and with an obsolete furrow; " prothorax transverse, set above with cylindrical spines which " are truncate and bear a puncture at apex; elytra roundedly " acuminate at apex, granulato-striate at base, simply striate " towards apex, suture and dorsal intervals with a single row of " granules. "Apart from H. transvaalensis Peringuey and tlxe present " species no Hipporrhinus has been described in which tlxe thox-ax "is set with cylindrical spines as in Epichthonius. But Mr. " Peringuey's species is 30 m m . long and has no rostral horn. " Upper surface of rostrum plane, with two lateral carina1 " uniting towards the base to form a bifid horn and enclosing a " triangular space which is faintly carinate in the middle. " Antex-ior margin of thorax faintly bisinuate and with broad " ocular lobes ; the cylindrical spines become coxxvex-ted latex-ally " into tubex-cles, which latter, as also the shax-p tubercles on the " elytra, bear a blackish depressed seta which is set in a puncture "and directed backwards. The thorax and elytra closely set with " round bare spots. Tlxe underside with vexy sparse haix-s, squamose " only towTards tlxe sides. Femox-a with a dense ring of scales near " the apex.

Dr. Faust's statement that no previously described species except transvaalensis Per. possesses cylindrical spines on the thox-ax is incox-rect, for both spinicollis Gyl. and thoracicus Fahr. exhibit in a marked degree this charactex-, which, mox-eover, is not present in transvaalensis. However, coronatus is tlxe only described species which has spines on the thox-ax in conjunction with a rostral hox-n. 117. H. CONSORS Mshl. (Plate IV. fig. 4.) //. consors Mshl. 1. c. p. 444 (1902). Long. 11, lat. 5| m m. Head with dense bi-ownish scaling, vex-tex convex, forehead plane and without carina or fovea; anteocular- furrows distinct but not vexy deep. Rostrum not incised at base, shoxter than prothorax only, vexy little curved, dilated to apex. Upper surface closely but faintly punctux-ed, densely covered with greyish scaling, with a large tubercular horn close to base, which is strongly bifid and distinctly dilated at apex; the anterior part without furrows and smooth except for a vexy faint centx-al carina ; both pairs of lateral sulci almost obsolete ; scrobes deep, lateral and oblique; inferior basal fux-row deep. Antennce short, thick and squamose ; scape just reaching eye ; the two basal joints of funicle subequal, not much longer than tlxe others. Prothorax transverse, apex and base of equal width, sides strongly rounded, broadest rather before middle, with a txansverse impression near apex, dorsal anterior-margin truncate, ocular lobes well developed. Upper surface convex, fairly closely set with small rounded tubercles, leaving a narrow central furrow without a carina; tubercles bare and with |
