decidedly from all other species of Sarticus and Notonomus. The 

 prothorax and the elongate tenth elytral interstice suggest affinity 

 to Notonomus, while the ventral segments are those of Sarticus. 

 It is, I consider, more allied to Notonomus inediosulcatus, Chaud., 

 than to any other described Australian species, but the affinity 

 between these species is remote; so much so, that, even if 

 the subgenus Adefipa, which Castelnau founded on N. medio- 

 sulcaf?is, were recognised (as I have no doubt it will be by 

 specialists sooner or later), S. impa?- would hardly come into it. 

 Its reference to Sarticus, I regard as preferable to resuscitating 

 the subgenus Adetipa, where it would be, in any case, only doubt- 

 fully more in place than in Sarticns. A ridgid specialist would 

 doubtless recognise as ^uhgenevsi Adetipa ?in(l Coronocanthus; but, 

 if this course be adopted, then named groups would be required 

 for*S articus blackbur^ii, 81., *S'. impar, Notonomus molestus,^ Chaud., 

 (and allied species), and probably iV. miles, Casteln.; in fact, once 

 admit subgenera, and a desire to give uniformity to classification 

 seems to demand that each fairly distinct species, or group of 

 species, shall receive a generic cognomen till an ordinary mind is 

 bewildered by a numerous array of genera which no one without 

 a special (and usually artificial) system can differentiate from one 

 another. 



Sarticus cyaneocinctus, Chaud. 



Feronia (Steropus) cyaneocincta, Chaud., Bull. Mosc. 1865, ii. 

 p. 97: F. ( Pterostichus) azureomarginata, Casteln., Trans. Roy. 

 8oc. Vict. viii. 1868, jd. 215: F. (Steropus) saphyreomarginata, 

 Casteln., I.e. 222: Sarticus saphyreomarginatiis, (Qsi^iein.) Chaud., 

 Ann. Mus. Civ. Genov. vi. 1874, p. 595: Sloane, Proc. Linn. Soc. 

 N.S.W. 1889, (2) iv. p. 505. 



The name S. cyaneocinctus, Chaud., must stand for this species, 

 being the earliest. Chaudoir, who latterly regarded Sarticus and 

 Ilomalosoma as both merely subgenera of Feronia, considered his 

 name preoccupied by Hoynalosoma cyaneocincta, Boisd.; but now 

 that the old subsjenus Homalosoma is recognised as a valid ijenus 

 (Castelneaudia), this synonymy cannot be maintained. 



* The subgenus Ternox has been proposed by Motschusky for this species.
