Intervals 3 and 5 with the tubercles depressed and oval 

 from base to declivity, theuce conical ; rostrum with 

 a rounded impression at base. 



Ocular lobes of prothorax only slightlj' developed; 

 intervening granules in striae minute, rows quite 

 regular 54. S. recurmis F. 



Ocular lobes of prothorax well developed ; intervening 

 granules in stride larger, the rows irregular and 

 often confused 55. H. albolineatus Fahr, 



Intervals 3 and 5 vi'ith the tubercles conical through- 

 out; rostrum without a rounded impression at 

 base; ocular lobes well developed ... 53. S. sulcirostris Fkhr. 



Rostrum without a distinct continuous central furrow, 

 at most very shallowly excavate. 



Dorsal edges of rostrum rounded at base, carinate only 

 near apex ; rostrum with a central stria at base. 



66. S. ffi/Uen7iali Gj'l. 

 Dorsal edges of rostrum strongly carinate from base 



to apex ; rostrum with no central stria at base. 



58. IT. macidatus Mshl. 



Rostrum with a transverse basal furrow on the under- 

 side. 



Dorsal edges of rostrum produced upwards into a 

 sharp projection above the insertion of antennae. 



67. S. nivosus Sparrm. 

 Dorsal edges of rostrum without any sharp projection. 



Elytra with irregular, and often confused, rows of 

 large granules in lieu of punctures ; legs with large 

 round white scales 61. JET. insignis Falir. 



Elytra with regular rows of minute granules ; legs 

 with narrow scales. 



Intervals 3, 5, and 7 with rows of large separated 

 tubercles which become very long, sharp and 

 curved towards apex; legs with scattered narrow 

 white scales 60. S. spiculostis Gjd. 



Intervals 3, 5, and 7 subcostate, with rows of small 

 closely-set and often duplicated tubercles which 

 become rather larger and conical towards apex ; 

 legs with brown setiform scaling 59. II. globifer F. 



Either or both pairs of lateral sulci on rostrum 

 uniting (or running into the central furrow) near 

 the base, which is usuallj^ raised above the plane of 

 the forehead. 



Alternate intervals on the elj'tra uneven. 



Scrobes directed beneath base of rostrum. 



Inferior basal transverse furrow on rostrum absent. 



Sides of prothorax not angulated but rounded. 



Interval 2 tuberculate at least on the apical half. 



Elytra with separated sharplj' conical tubercles, at 

 least towards the sides and apex. 



Dorsal edges of rostrum not carinate ; prothorax 

 fairly closely set with low rounded tubercles, its 

 dorsal anterior margin truncate 62. jET. vafer Gyl. 



Dorsal edges of rostrum stronglj' carinate ; prothorax 

 very sparsely set with large depressed tubercles, its 

 dorsal anterior margin distinctly sinuate. 63. S. knysna, sp. nov. 



Elj'tra without prominent conical tubercles, the 

 alternate intervals subcostate and with small, 

 closely-set, subcatenulate tubercles. 



Ocular lobes well developed; eyes subdepressed ; form 



robust 65. IE. transvaalensis Per. 



Ocular lobes feeble; eyes very prominent; form 



narrow 64. II. sexvittatus F. 



Interval 2 entirely devoid of tubercles. 66. II. delectans Hbst. 



Sides of prothorax dilated and bluntlj^ angulated. 



Elytra oblongo-ovate, sides subparallel ; the alternate 

 intervals slightly carinate, but the tubercles dis- 

 tinctly separated 74. if. wyasce, sp. nov.
