30 MR. G. A. K. MARSHALL ON COLEOPTERA [Jan. 19, 



much broader in proportion to its length ; in that the intervals 

 2, 4, and 6 on the elytra are broader and quite plane and that the 

 interval 2 has no sign of a tubercular prominence at its base ; 

 finally, in perfect specimens, the colouring is strikingly distinct. 



10. H. SETULOSus Gyl. 



H. setulosus Gyl. Schh. Gen. Cure. v. p. 777 (1840). 



Long. 20, lat. 8 mm. 



Head convex, with the punctuation close and fine on vertex, 

 fainter and more diffuse in front, forehead without a carina or 

 fovea ; eyes surrounded by a deep impi'essed ring ; anteocular 

 furrows distinct. Rostrum separated from head by a deep dorsal 

 incision, very thick and distinctly curved, as long as head and 

 prothorax. Upper surface without any central furrow, rugosely 

 punctured and vvith 5 narrow carinse, the central one narrower 

 and less distinct than the others; scaling absent, replaced by 

 short, erect, paler setae ; lateral sulci deep and of about equal 

 length, the upper pair meeting at base; scrobes lateral and 

 parallel to the sulci ; inferior basal furrow very deep. A7itennce 

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

 subequal. Prothorax transverse, apex and base of about equal 

 width, sides strongly rounded, broadest about middle, dorsal 

 anterior margin truncate, anteocular lobes sti'ongly developed. 

 Upper surface rather convex, closely set with small rounded 

 tubercles leaving a central furrow containing no carina ; tubercles 

 with short depressed setse., interstices with sparse suberect pale 

 setae. Elytra ovate, shoulders rounded, sides slightly rounded, 

 broadest before middle, apices bluntly prominent. Upper surface 

 rather convex, with regular rows of large shallow punctures 

 separated by distinct granules, the intervals costate, the alternate 

 ones more strongly so ; intervals 3, 5, and 7 with regular a,nd 

 complete rows of small, closely set, subconical tubercles, those on 

 the declivity of 3 being a good deal larger than the others; 

 intervals 1 and 2 are quite plane ; interval 4 has a short row of 

 granules, lai-gest near base and disappearing behind middle; 

 interval 6 has a complete row of small granules ; apices of tubercles 

 with short erect pale setse, their sides and the rest of the elytra 

 thinly clothed with yellow recumbent setse instead of scales. 

 Legs with only scattered pale setse ; posterior tarsi with the three 

 basal joints subequal in length and breadth. 



Cape Colony. 



This species can be easily distinguished from all its near allies 

 by the setose, instead of squamose, elytra. 



11. tH. GRAviDus, sp. nov. 



Long. 17-19, lat. 8-9| mm. 



Head convex, very rugose and with sparse white scaling ; ante- 

 ocular furrows rather indistinct. Rostrum separated fi-om head 

 by a distinct dorsal incision, as long as prothorax only, moderately 

 curved, its sides subparallel throughout, but with the gena; dilated.
