Species of South- African Cmculiomclx, 415 



HipporrJiinus hrachyceroides^ sp. n. 

 Long. 22, lat. 9 millira. 



Head convex, without any central carina or fovea; the 

 punctuation hidden by very dense brown scaling, anteocular 

 furrows distinct. Rostrum not incised at base, as long as 

 head and thorax, strongly curved ; at base a large stout double 

 horn, the apices of which are divergent. Upper surface with 

 a broad central furrow throughout and thiclcly covered with 

 large whitish scales. The lateral sulci are broad and dis- 

 tinct, coarsely punctured and filled witli scales; the interval 

 between them narrowly carinate ; the basal transverse furrow 

 beneath very deep ; scrobes directed below base of rostrum. 

 AntenncB black, setose ; scape not reaching eye ; first and 

 second joints of funicle subequal. Prothorax as long as 

 broad, apex narrower than base, sides very little rounded, 

 broadest about middle, ocular lobes very strongly developed. 

 Upper surface convex, irregularly set with conical tubercles, 

 leaving a broad central furrow containing a short but strong 

 carina ; apices of tubercles bare, each with a puncture con- 

 taining a depressed seta, interstices with dense variegated 

 scaling. Elytra oblong, slioulders prominent, sides sub- 

 parallel for three-fourths of the length, apical processes very 

 short. Upper surface convex, with regular rows of shallow 

 foveolse : interval 1 entirely devoid of granules or tubercles ; 

 interval 6 with a more or less abbreviated row of tubercles, 

 sometimes wanting; the remaining intervals with regular, 

 complete rows of small, conical, closely-set tubercles — except 

 that on interval 4, which ceases at the summit of the declivity ; 

 the tubercles increase slightly in size towards apex, being 

 subcristate on the declivity of the second interval. The entire 

 surface, including the apices of the tubercles, is densely 

 clothed with variegated grey and brown scaling. Legs 

 short and thick, densely clothed with light-coloured scales 

 and setge ; second and third joints of posterior tarsi subequal, 

 distinctly shorter than first, all three of about equal width. 



Cape Colony : Namaqualand. 



A very distinct species, approaching the aberrant Dregeiy 

 Gyl., but, apart from being smaller and of a different colour, 

 the rostral horn is much larger and the apices divergent ; the 

 thoracic tubercles are smaller, more conical, and more closely 

 set; the prosternum has a strong conical projection just in 

 front of the anterior coxa3 ; the large intra-apical tubercular 

 prominence of Dregei is represented only by a very sligiit 

 elevation in hrachyceroides. The prosternal projection is, so 

 far as I am aware, unique in the genus, although ruhifer, F., 

 and some of its allies have a slight fold in the same position.
