The number of names of previously - described species 

 confidently attributable to this Group is 51. I add 27 new 

 names in the following pages. There are also 10 previously- 

 described species which cannot be confidently placed in any 

 Group without inspection of types that are not in Australia, 

 but which probably are members of this or the preceding 

 Group. They will be found enumerated in the Supplement 

 following. Three species (of the 51 mentioned above) are not 

 placed in the tabulation (vide infra) as the types are in 

 Sydney, and I have not been able to examine them. They 

 are Erichsoni, Blackb., marginatus, Blackb., and scutatus, 

 Macl. Five names (of the 51 mentioned above) are synonyms, 

 and will be found enumerated in the Supplement. The re- 

 maining names are placed in the tabulation : — 



A. Male elytra black at base; pronotum 



clothed with long hairs in both sexes ; 



elytra striate. 



B. Punctures of pronotum very close (10 



from front not reaching middle) , 



C. Antennal flabellum dark. 



D. Elytral interstices not conspicu- 

 ously and evenly convex. 

 E. Prothorax at its widest scarcely 

 behind middle ; sides very 

 strongly rounded ... 

 EE. Prothorax at its widest con- 

 siderably behind middle ; sides 

 only moderately rounded. 

 F. All the elytral interstices 

 flat, striae very faint, basal 

 black of male elytra wide 

 FF. Alternate elytral inter- 

 stices convex, striae strong, 

 basal black of male elytra 



narrow 



DD. Elytral interstices strongly and 



evenly convex 



CC. Antennal flabellum testaceous ... 



BB. Punctures of pronotum much less 



close (10 from front well passing 



middle) ; antennal flabellum bright 



ferruginous 



AA. Species not combining the characters 



of A. 

 <3) B. Hind coxae not or but little shorter 

 than metasternum (vide supra in 

 general remarks). 

 C. Elytral punctures very close (20 

 from suture not passing the 

 middle).
