N.B. — As the last three species described aljove liave a con- 

 isiderably difierent facies from EjmrcEa, owing to the very narrow 

 lateral margins of their prothorax, I should have hesitated to 

 refer them to Haptoncura, were it not for their being evidently 

 close allies of H. lilij^utana, Reitter. It will perhaps be well to 

 mention that they possess the characters which in Herr Reitter's 

 tabulation of the NitiduHdfH (verh. ver. Briinn, 1873) would refer 

 them to Epurft^a (from which genus Haptoncura has since been 

 separated), viz., prosternum not produced hindward, tarsi dilated, 

 elytra nearly covering the pygidium, labrum emarginate, apex of 

 mandibles simple, and in addition the tibia? distinctly spined at 

 the apex and other characters distinguishing Haptoncura. 



The described Australian species may be thus tabulated : — 

 A. Lateral margins of prothorax widely reflexed. 

 B. Elytra! markings consisting of a 



dark vitta ... ... ... Victoriensis, Blackb. 



BB. Elytra not marked as in fimperialis, Reitt., 

 Victoriensis ... ... ... l^subquadrata, Reitt. 



AA. Lateral margins of prothorax extremely narrow. 

 B. Prothorax rectangular at base 



(colour uniformly testaceous) liliputana, Reitt. 

 BB. Hind angles of prothorax more or less roundly obtuse. 

 C. Prothorax and elytra differently punctured inter 

 se. 

 D. Prothorax closely 



punctured ... Meyricki, Blackb. 



DD. Prothorax faintly 

 and less closely 



punctured ... Lindensis, Blackb. 

 CC. Puncturation of upper 



surface quite uniform uniformis, Blackb. 



NITIDULA. 



N. quadripustulata, Fab. This species (doubtless imported) is 

 not uncommon in the neighbourhood of Adelaide. I have not 

 seen any previous notice of its occurrence in Australia. 



SORONIA. 



S. simidans, sp. no v. Sat late ovalis ; pubescens ; crebre punctu- 

 lata ; nigro-picea ; prothoracis elytrorumque lateribus (his 

 sat angustis) antennis pedibus et corpore subtus rufescenti- 

 bus ; prothorace quam longiori plus duplo latiori, antrorsum 

 fortiter angustatis, antice sat fortiter vix bisinuatim emar- 

 ginato, angulis posticis rectis retrorsum leviter productis ; 

 elytris sub-seriatim punctulatis, interstitiis alternis fulvo- 

 pubescentibus. Long., 2-} 1. ; lat., 1^- 1. (vix). 

 Agrees with Soronia in all generic cliaracters, T think, — elytra
