436 REVISIONAL NOTES ON AUSTRALIAN CARABIDiE, i\ r ., 



ruption. Intercoxal declivity of prosternum narrow in middle, 

 of mesosternum concave. Length, 20; breadth, 6*8 mm. 



#a&.-N.S.W. : Ebor (Tillyard). Unique in Coll. Sloane. 



This large, black species is one of the most distinct in the 

 genus, having the prothorax more strongly sinuate to the base 

 than any other species. It is probably more allied to N. violaceus 

 Cast., than to any other species. The anterior tarsi in $ are 

 much less dilatate than in N. violaceus and N. triplogenioides. 

 The four posterior tarsi have the first joint without any spinules 

 beneath the external costa, which is obsolete on the hind tarsi. 



The parallelo?no?yhus-gro\ip. 



Prothorax as long as broad; posterior marginal puncture on 

 border at basal angle. Elytra simply striate; eighth interstice 

 a little wider than ninth on basal half, ninth narrow. Inter- 

 coxal declivity of prosternum wide, flat. Tarsi not striolate on 

 upper surface, first joint of four posterior tarsi costate externally, 

 without spinules beneath costa. Apex of abdomen 6-setose in $. 



A monotypic group, with relationships to both the eques- and 

 australis-gvoups, but which it seems better not to associate with 

 either. 



55. JV r . parallelomorphus Chaud.,( = iV. opulentus 81., Revision, 

 1902). — I can now see that I made a mistake in considering N. 

 parallelomorphus as a synonym of N. opulentus Cast., to which it 

 has no particular affinity. This species has the apical ventral 

 segment setose as in the elites-group, namely, $, 2-setose; £, 

 6-setose. The first joint of the anterior tarsi in £ is often 

 squamulose beneath (this also occurs in N. eques Cast., and rarely 

 in N. bodece SI.); it is so in four out of nine specimens taken by 

 me at Warburton and Marysville, Victoria. 



The australis-group. 



Prothorax with posterior marginal puncture on border at 

 basal angle. Elytra with striae crenulate; third interstice bear 

 ing more than two punctures. Intercoxal declivity of pro- 

 sternum flat. First joint of four posterior tarsi costate ex- 

 ternally, without spinules beneath costa.
