indeed does any single species of the present day show all of 

 them) are ancient characters : head large, prothorax with pos- 

 terior marginal puncture not on border ; elytra fully striate, 

 third, fifth, and seventh interstices bearing setiferous pores, tenth 

 interstice not greatly developed, basal border meeting lateral 

 border at humeral angles without interruption; intercoxal de- 

 clivity of prosternum rounded in middle; posterior femur con- 

 siderably swollen on lower side behind apex of trochanter; tarsi 

 with upper surface striolate, first joint of four posterior tarsi 

 costate on outer side, the costa spinulose on lower side, onychium 

 setulose beneath. 



"*89. iV 7 . opacistriatus SI. — I now see that this species is not a 

 true species of Notonomus, but requires a new genus for its re 

 ception; therefore, it is not included in Notonomus in this paper. 



Species uyiknown to me. 



22>.N. resplendens Cast., is closely allied to the species I have 

 named iV. metallicus) but I have been unable to consider iV r . 

 metallicus the same as il r . resplendens, on account of its smaller- 

 size, and its want of a "beautiful red-gilt margin." I had formed 

 a wrong idea of N. resplendens in 1902, and now see that it is not 

 allied to N. eques Cast., as I had thought. 



35. N. striaticollis Cast., seems allied to N. polli SI., but it 

 would be mere guess-work to think these the same; no doubt N. 

 striaticollis could be identified, if specimens from the Clarence 

 River were available for examination. 



45. iV. depressipennis Chaud., vide Sloane, These Proceedings, 

 1902, pp.305, 306. 



60. N. darlingi Cast., I have not seen; it is, perhaps, more 

 allied to JV 7 australis Cast., than to N. nitidicollis Chaud., the 

 species with which Chaudoir compares it in his " Supplement." 



75. N. subiridescens Chaud., seems allied to, but different from, 

 N. liragerus SI. 



76. N. ingratus Chaud. All my attempts to identify this 

 species have failed, nor do I think I have ever seen it; probably 

 it is allied to X. scotti SI.

 indicate the position in the genus, and correspond with those in the index
