may be noted that in £, the border of the elytra has, on each side, 

 a rather prominent triangular projection just behind the lateral 

 apical sinuosities, a character found nowhere else in the genus. 



21. JV. opulentus Cast.,(= N. bassi SI.). — I now perceive that, 

 through not knowing N. resplendens Cast., the species with which 

 Chaudoir compared N. opulentus in his "Supplement," of 1874, I 

 identified JV. opulentus Cast., wrongly in my " Revision." This 

 error is regrettable, because I was thereby led into describing as 

 new, under the name of N. bassi, what is evidently merely a form 

 of N. opulentus, a species subject to considerable variation. 



Var. gippslandicus Cast. — Chaudoir thought this only a form of 

 N. opulentus, and I believe he was right. It is distinguished by 

 its green colour. Hab. — Marysville (Sloane).
