420 REVISIONAL NOTES ON AUSTRALIAN CARABIDiE, iv., 



A 7 , jrenchi, at Warburton, on the Upper Yarra. I have no hesita- 

 tion in referring these Warburton specimens to N. plutus Cast, 

 Sometimes there are two punctures on the fifth interstice of the 

 elytra, sometimes one, and sometimes none. 



Hob. — Victoria : Warburton and Marysville, in damp, heavily 

 timbered gullies. 



N. crcesus Cast. — Specimens given to me by Mr. C. French, as 

 from the Baw Baw Mountains, are probably N. croesvs. Chaudoir 

 thought that N. crcesus Cast., and N. plutus were merely forms 

 of one species; and, if I am right in my identification of N. 

 crcesus, I concur. The form I take to be N. crcesus is differ- 

 entiated from N. plutus by prothorax less strongly sinuate before 

 base, basal angles less decidedly marked; elytra more deeply 

 striate and less brightly coloured.
