subtilibus seriatim impressis ; prothorace quam longiori ut 



2 1 ad 1 latiori, antice angustato, margine antico fortiter 



bisinuato; elytris haud striatis, stria subsuturali etiam 



carenti. Long., 3 1.; lat., 14 1. 



This species is very much more finely and closely punctulate 



than C. Mastersi, Macl. The absence of a subsutural elytral 



stria distinguishes ii from all the other described Australian 



Cyclonota.

NOTOCERCYON (gen. nov. Sjjhceridiidar'ioin). 



Palpi labiales breves; palpi maxillares modici, articulis 2° 



dilatato, 3° 4° que gracilibus inter se sat iequalibus ; labrum 



vix perspicuum ; oculi modici; antennse ut Cercyonis : 



scutellum modicum triangulare ; elytra pedesque ut 



Cerycoyds ; prosternum ut Cercyonis : mesosternum sat late 



lanciforme planum ; corpus supra parce pubescens. 



This genus differs from Cercyon chiefly by the form of the 



mesosternum which is flat as in Meyasteriium, though not quite 



so wide as in that genus and much longer. It differs from 



Megasternum in having the prosternum and tibiae as in Cercyon. 



R. ornatujn, sp. nov. Ovale, postice acuminatum ; convexum ; 



parce pubescens ; rufobrunneum, prothorace rufo, elytris 



testaceis (striis nigris, interstitiis interrupte nigro-maculatis, 



maculis fascias duas indeterminatas formantibus), 



antennarum clava nigra ; capite prothoraceque subtiliter sat 



sparsim punctulatis ; hoc fortiter transverse ; elytris fortiter 



striatis, striis minus perspicue punctulatis, interstitiis 



subtiliter punctulatis (puncturis singulis capillas singulas 



ferentibus) convexis ; metasterni mesosternique parte 



mediana planata sparsim punctulata. Long., 4 1. ; lat., ^jj 1. 



I met with two specimens of this insect, which are similarly 



coloured. The species differs from the following in its form 



acuminate behind, the evidently finer and sparser puncturation 



of its prothorax, and the much less close puncturation of the 



flattened surface of its meta- and mesosterna.

iV^. (Cercyon) dor sale, Er. T met with several specimens near 

 Hobart of an insect which agrees very well with Erichson's 

 description of this species, and I have it also from several locali- 

 ties in the Victorian Mountains. It is evidently congeneric with 

 the species for which I have proposed the generic name 

 JVotocei'cyon. In colouring it presents considerable variety, the 

 typical form (with which one of my Tasmanian examples agrees), 

 has the piceous colour on the elytra in the form of a common
