1904.] OF THE GENUS HIPPORRHINUS, 137 



'' small setae, the intervals faintly gi'anulate ; black, with alter- 

 " nating lines of dense white scaling. Body punctured beneath, 

 " black, with sparse white scaling. Legs rather long, stout, black, 

 " obsoletely punctured, and with white scaling. 



" Cape of Good Hope. Described from the collection of 

 " Mr. Dr^ge. 



" Less than half the size of Hipporrhimis sit,hvittatt(,s, notably 

 " shorter, the rostrum differently constructed, the thorax short, 

 " densely tuberculate, &c." 



I have been unable to identify this species with any certainty, 

 and the above description is taken from Gyllenhal.

Long. 12-14, lat. 5-6 mm. 



Head convex, closely and confluently punctured, with dense 

 brownish scaling, forehead rather flattened and with a faint 

 central carina ; anteocular furrows absent. Rostrum not incised 

 at base, as long as prothorax, slightly curved and dilated towards 

 apex. Upper surface closely punctured and scaled, with five 

 smooth narrow carinse, the three central ones converging towards 

 base to form a distinct elevation ; lateral sulci shallow, subtri- 

 angular in shape and of about equal length, the upper pair uniting 

 at base ; scrobes lateral, rather shallow ; inferior basal furrow 

 absent. Antennce with scape just exceeding posterior margin of 

 eye ; the two basal joints of funicle subequal, Prothorax broader 

 than long, apex narrower than base, sides distinctly i"Ounded, 

 broadest rather behind middle, dorsal anterior margin truncate ; 

 ocular lobes almost obsolete. Upper surface convex, rather 

 sparsely set with small elevated tubercles, leaving a distinct central 

 furrow containing no cai'ina ; tubercles bare, with depressed pale 

 setae, the interstices with dense whitish or greyish scaling. Elytra 

 narrowly ovate in S , broadly ovate in $ and acuminate apically, 

 shoulders roundedly prominent, sides rounded, broadest about 

 middle, apices jointly rounded in S , slightly divergent in $ . 

 Upper surface convex, the striae with rows of obscure punctures 

 separated by minute granules, the intervals slightly convex, 

 coriaceous, with faint granulation latei-ally, and all with regular 

 rows of depressed pale setae ; scaling whitish or greyish, usually 

 with the intervals 1, 3, 5, and 7 more or less denuded. Legs with 

 moderately dense pale setiform scaling ; posterior tarsi with the 

 2nd joint rather narrower than the othei- two, 2nd and 3rd sub- 

 equal in length, 1st longer. 



Natal : Durban, Estcoui-t. Transvaal : Lydenburg. 



Type of cinerascens in the Stockholm Museum. 



I can only regard cinerascens Fahr. as a colour variety of this 

 species, lacking the conspicuous striping, as I can detect no other 

 essential difference ; moreover, I have fovmd the two forms 

 inhabitins: the same localities.
