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 con- 

 spicuous large scattered punctures : upper latei-al sulci absent, 

 lower pail- shallow ; scrobes directed beneath base of rostrum ; 

 inferior basal furrow present. Antenncs sliort, scape scarcely 

 reaching eye ; the two basal joints of f unicle subequal. Prothorax 

 scarcely longei- than the width at base, apex narrower, sides 

 dilated before middle into a strong recurved spine, anterior margin 

 convex, ocular lobes moderate. Upper suiface somewhat convex, 

 with a deep central furrow, bordered by a tubercular costa in its 

 interior half and containing a strong smooth carina ; the lateral 

 portions are rather sparsely set with small rounded tuljercles ; 

 costee and tubei'cles bare, the interstices with dense fulvous scaling. 

 Elytra ovate, broadest about middle, shoulders roundedly promi- 

 nent, apical processes in $ long, stout and sharp. Upper surface 

 convex, irregularly and transvei^sely subi'eticulate, the intervals 

 3, 5, and 7 more raised than the othei-s, subcostate, but more or 

 less distinctly tuberculate towards apex ; the remaining intervals 

 with interrupted and incomplete rows of depi-essed tubercles. 

 Tubei'cles bare and shiny, the interspaces densely covered with 

 small fulvous scales. Legs variegated with pale scaling ; postei'ior 

 tarsi bi-oad, spongy beneath, the joints of the same width, 2nd 

 and 3rd of equal length, 1st rather longer. 



Transvaal : Rustenburg. 



Type in Mr. Peringuey's collection. 



The sculpturing of the elytra differs very markedly from that 

 of the other large species which have lateral spines on the pro- 

 thorax.

Long. 23-29, lat. 9-12 mm. 



Head convex, with close shallow punctuation and fulvous 

 scaling, forehead without fovea or carina ; anteocular furrows 

 deep, subconvergent above. Rostnmi not incised at base, as long 

 as head and prothorax, strongly curved and dilated fi-om middle 

 to apex. Upper surface with a deep central furi-ow throughout, 

 dilated anterioi'ly and containing a distinct rounded impression 

 at base ; the furrow impunctate, but the adjoining costfe coarsely 

 punctured and 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 ; the two basal joints 

 of f unicle subequal. Prothorax transverse, the length equal to 

 width at base, apex narrower, sides ampliated and armed about 

 middle with a sharp tubercular spine, dorsal anterior mai^gin 

 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
