sides ; apex emarginate; basal angles obtuse, hardly marked; 

 border wide, especially towards base, passing round basal angles 

 on to sides of base; posterior marginal puncture on the border at 

 basal angle ; median line strongly impressed ; lateral basal 

 impressions rather long, deep, parallel. Elytra ovate (8x5 mm,), 

 depressed on disc, declivous in a gentle slope to apex, strongly 

 sinuate on each side of apex; basal border with posterior margin 

 arcuate and raised above plane of elytra, joining lateral border 

 without interruption at humeral angles ; lateral border widely 

 reflexed, carinate near base; eighth interstice convex, narrow (but 

 wider than ninth on basal half), ninth very narrow in ^, and 

 interrupted on inner side by the umbilicate punctures, tenth 

 feebly developed just in front of the apical sinuosities. Length 

 12-5-16, breadth 4-3-5-8 mm. 



Hab. — N.S.W. : Manly (Fletcher), Narrara and Ourimbah

Allied to iV. marginatus, Casteln., of which it may be a variety 

 without the bright border to the elytra. Compared with what I 

 consider the typical form of A", marginatus. the 9 has the pro- 

 thorax proportionately longer and narrower at the base ; the 

 elytra more depressed with more convex interstices, the eighth 

 especially being narrower and more convex. I cannot differentiate 

 it from the species from Spring wood which I have placed under 

 N. 7yiarginatus as var. luculentus, except by the absence of the 

 bright cupreous lateral channel of the elytra, but I believe it to 

 be a distinct species.
