The description given above is founded on a specimen ((J)from 

 Dunoon. I took it plentifully at Ourimbah and Narrara; the 

 form from these localities is more elongate and more convex, 

 with prothorax and elytra proportionately more elongate and less 

 ampliate at widest part than specimens from Dunoon, but I have 

 not thought it sufficient!}'- distinct to receive a separate name. 



NOTONOMUS EXCISIPENNIS, n.Sp. 



Elliptical-oval. Head moderate ; prothorax subcordate ; 

 posterior angles rounded; posterior marginal puncture a little 

 before base in lateral channel : elytra truncate-oval, strongly 

 striate; interstices strongly convex, third 2-punctate, eighth ver}^ 

 narrow. Under surface and legs piceous-black ; head black, 

 sometimes with a bronzy reflection; prothorax metallic-purple, 

 brighter towards sides, nearly black on disc; elytra of a dark 

 purple tint, often viridescent towards suture; purple on lateral 

 declivities, more obscure near lateral margins. 



^. Head rather large (3-3 mm. across eyes); front a little 

 depressed, lightly biimpressed ; eyes convex, prominent. Pro- 

 thorax broader than long (3-8 x 4-7 mm.), a little narrowed to 

 base, hardl}' narrower at base (3-1 mm.) than apex (3.2 mm.); 

 sides lightly rounded, not sinuate before base ; apex truncate, 

 angles widely obtuse; base truncate, rounded on each side near 

 angles, these not marked; lateral border line, narrow, continued 

 evenly round basal angles to middle of lateral basal impressions; 

 median line strongly impressed; lateral basal impressions strongly 

 impressed, parallel, not long. Elytra truncate-oval (9*5 x 5 -5 mm.), 

 lightly rounded on sides; humeral angles rounded; basal border 

 meeting lateral border without any interruption at humeral angles; 

 lateral sinuosities of apex strongly developed. Intercoxal declivity 

 of prosternum rounded ; of mesosternum concave. Anterior 

 femora thick and greatly swollen in middle. 



9- Head a little larger than in (J; space between ninth inter- 

 stice and border of elytra very wide and obliquely truncate pos- 

 teriorly, the lateral sinuosities of apex being exceptionally 

 strongly developed. Length 15-5-18, breadth 5-6*2 mm.
