306 REVISION OF THE GENUS NOTOyOMUS, 



lateral border and channel wide; posterior marginal puncture 

 foveiform, placed a little distance from basal angle on inner side 

 of marginal channel; median line strongly impressed, reaching 

 from base almost to apex; lateral basal impressions short, narrow, 

 deep, uniting with lateral channel at base. Elytra lightly convex, 

 oval (7 '5 X 4 mm.), evenly and decidedly rounded on sides, widely 

 sinuate on each side of apex; lateral channel and border wide. 

 Intercoxal declivity of prosternum flat; of mesosternum vertical 

 and lightly concave. Femora short, stout; posterior femora very 

 thick in middle. Length 13, breadth 4-6 mm. 



Hab. — N.S.W. : Richmond River (Froggatt and Lea). 



Var. A. Smaller: prothorax less strongly rounded on sides 

 and more narrowed to base; basal angles more marked: elytra 

 more depressed on disc; interstices opaque in both sexes: colour 

 duller; elytra purple-black, margined with green. 



Hab. — Tweed River (Lea). 



Differs evidently from N. depressijyennis, Chaud., by prothorax 

 shorter and without the juxtabasal sinuosities of sides. I have 

 thought that it could not be N. striaticoUis, Casteln., because of 

 its short, broad thorax, not " considerabl}' longer than broad."

Black, elytra with metallic border. Prothorax roughly 

 shagreened and transversely striolate, transverse (4-3 x 5-4 mm.), 

 much wider at base (4-2 mm.) than apex (3 5 mm.); posterior 

 angles rectangular ; posterior marginal puncture in marginal 

 channel at basal angle. Elytra deeply striolate; interstices nitid 

 and convex in ^ (sometimes rather metallic), depressed and opaque 

 in 9, third 2-punctate, second, fourth and sixth wide and foveolate 

 on apical third, eighth wider than seventh at basal third, ninth 

 narrow, convex, with inner side interrupted by large umbilicate
