412 REVISIONAL NOTES ON AUSTRALIAN CARABID.E, IV., 



with upper surface striolate; four posterior tarsi with basal joint 

 strongly costate on outer side, hind tarsi without spinules below 

 costa of outer side of first joint. 



The elites-group seems a natural one, probably of ancient 

 origin. It shows slight affinities with the sphodroides -group, 

 through iV. strzeleckianus and allied species; and, also, vaguely 

 towards the opacicollis-group, through JV. eques and allied species. 

 The e<^es-subgroup has remote affinities towards the cupricolor- 

 and jwallelomorphus-groups. Here, the first joint of the inter- 

 mediate tarsi has the external costa spinulose on lower side, but 

 in the hind tarsi there is no spinule. N. eques and closely 

 allied species have the onychium of the tarsi setulose beneath; 

 and, in N. froggatti, too, the onychium may have a single setule 

 on each side beneath, but this is not invariable. N. strzeleckianus, 

 N. phillipsi, and N. longus have the onychium glabrous beneath.
