1904.] OF THE GEXIJS HIPPORRHIXUS. Ill 



104. H. ciNEREUS, sp. nov. (Plate III. fig. 9.) 



Long. 11, lat. 4| mm. 



Read with scattered grey scaling and diflfuse faint punctuation, 

 vertex convex, forehead slightly flattened and without fovea or 

 carina ; anteocular furrows broad but shallow, disappearing 

 inferiorly. Rostrum not incised at base, as long as prothorax 

 only, comparatively thin, slightly curved and dilated near apex 

 only. Upper surface slightly convex, with five narrow carinse of 

 equal height, the sulci being rugosely punctured and having sparse 

 white scaling ; lateral sulci distinct, the upper ones longer and 

 uniting at base ; scrobes entirely lateral, straight and very little 

 oblique; inferior basal furrow deep. Antennce elongate, piceous 

 and finely pubescent ; scape barely reaching eye ; second joint of 

 funicle much longer than first. Prothorax slightly transverse, apex 

 narrower than base, sides moderately rounded, broadest about 

 middle, dorsal anterior margin truncate, ocular lobes prominent. 

 Upper surface slightly convex, moderately closely set with small 

 granular tubercles, leaving a narrow central furrow without a 

 carina ; apices of tubercles bare, shiny, and with a depressed white 

 seta, interstices with dense grey scaling. Elytra oblongo-ovate, 

 elongate, shoulders sloping, sides very little rounded, broadest 

 about middle, apical processes absent. Upper surface convex, 

 with rows of small pimctures, often with intervening granules, 

 intervals with more or less continuous rows of small granular 

 tubercles, which are subequal throughout; intervals 1, 3, 5, and 

 7 have the tubercles more numerous and nearer together than 2, 

 4, and 6 ; tubercles as on prothorax, the interstices with fairly dense 

 large round grey scales. Legs with scattered pale setae and a ring of 

 white scales near apex of femora; intermediate tibiae of S strongly 

 incurved at apex; posterior tarsi with the 2nd joint narrower 

 than the others, 2rLd and 3rd subequal in length, 1st longer. 



Cape Colony. 



Type in the British Museum. 



Somewhat resembling seriegranosus Gyl. in general facies and 

 the tarsal structui-e, but that species has the scape extending 

 beyond the anterior margin of the eyes, which are nearly twice as 

 large as in clnereits, and the scales on the elytra are very minute. 

 The nearest ally to cinereus, however, is cajncola Gyl. 



105. H. setiferus Gyl. 



ff. setiferus Gyl. Schh. Gen. Cure. v. p. 770 (1840) 



Long. 12, lat. 5| mm. 



Head convex, coarsely and closely punctured, forehead flattened, 

 anteocular furrows absent. Rostruvi not incised dorsally at base, 

 as long as prothorax only, not very thick and distinctly curved. 

 Upper surface convex, with five narrow but prominent carinse, the 

 three middle ones parallel throughout, the interspaces rugosely 

 punctured and with fine scaling ; lateral sulci distinct, about equal 

 in length, the upper pair coalescing at base ; scrobes entirely
