410 REVISIONAL NOTES ON AUSTRALIAN CARABIDiE, iv., 



77. N. semiplicatus Cast., (Pcecilus id.) should be allied to N. 

 opicalis SI., but it is vaguely described. It was impossible to 

 consider N. apicalis the same as N. semiplicatus, seeing that the 

 latter is said to have three punctures on the third interstice of 

 the elytra, while the former has only two. Whether N. semi- 

 plicatus is sufficiently described for its identification to be possible, 

 seems doubtful. 



Table of Species-groups. 

 l.(30)Episterna of metasternum short. 



2.(3)Point of prosternum setose between coxae cupricolor -group,
