the interspaces evenly covered with brown and yellowish scaling. 

 Legs coarsely punctured and with sparse pale scaling ; posterioi- 

 tarsi narrow, the joints of the same width, 2nd and 3rd subequal 

 in length, 1st much longer. 



Cape Colony : Cape Town. 



Type in the Stockholm Museum. 



In genei-al facies this species is veiy similar to Ci'isj^aius F., 

 and the two appear to be generally confused in collections ; the 

 rostrum, however, offers several good distinctive characters, as a 

 comparison of the descriptions will show.

 Schh. I.e. v. p. 757 (1840). 



Long. 11-22, lat. 5-10 mm. 



Head deeply and rugosely punctured, convex on veitex, fore- 

 head with a broad and very deep excavation ; anteocular furrows 

 absent. Rostrum not incised at base, about as long as prothorax, 

 thick, not much curved and slightly dilated towards apex, Uppei' 

 surface rugosely punctate, usually with a shallow central furrow 

 in the basal half, which is sometimes absent ; upper lateral sulci 

 broad and deep, uniting at base, the lowei' pair obsolete ; scrobes 

 deep, latei-al and oblique ; inferior basal furrow absent. Antennce 

 with scape barely reaching eye ; the two basal joints of funicle 

 subequal, Prothorax transverse, apex narrower than base, sides 

 ampliated to behind middle and then more or less sharjily con- 

 stricted, the ampliation thus often forming a distinct angular 

 projection, dorsal anterioi' margin slightly convex, ocular lobes 

 moderate. Upper surface almost plane, with a deep central 

 furrow, usually containing a faint trace of a carina, on each side 

 of the furrow a regular and often subcristate row of tubei^cles, 

 followed by a broad smooth space and then a less lateral row of 

 tubercles, some of which form the lateral angulation ; tubercles 

 bare, without setse, the intei'stices with thin greyish or brownish 

 scaling. Elytra oblongo-ovate, scarcely narrower in cj" , shoulders 

 subi-ectangular, sides scarcely rounded, apical processes very short 

 and conical in both sexes. Upper surface convex, with regular 

 rows of deep punctures, sometimes separated by low granules ; 

 interval 1 very narrow, occasionally with a few granules ; interval 

 2 with a row of distant tubercles from apex nearly to base, those 

 near apex miuch larger and more conical — very rarely this row is 

 entirely absent ; intervals 3, 5, and 7 with complete rows of 

 closely-set conical tubercles ; 4 and 6 devoid of tubercles, or at 

 most with one or two isolated ones ; tubercles bare, without seta?, 

 the interspaces with moderately dense brownish or greyish scaling. 

 Legs coarsely punctured and with sparse white scales ; posterioi- 

 tarsi broad, the joints of the same Avidth, 2nd and 3rd subequal 

 in length, 1st longer.
