262 EEVISION OF THE GENUS NOTOXOM US, 



in middle of disc; el3^tra purple with coppery reflections (the disc 

 darker and less metallic than the sides); under surface black, legs 

 reddish-piceous. 



Prothorax broader than long (4-9 x 5-8 mm.), widest before the 

 middle, strongly narrowed to base; sides rounded on anterior 

 two-thirds, strongly sinuate about posterior fifth and meeting 

 base at right angles; apex truncate, angles wide, obtuse; base 

 truncate, very lightly and widely emarginate in middle, narrower 

 (4-3 mm.) than apex (4-5 mm.); border wide; lateral basal im- 

 pressions elongate, wide; lateral basal spaces depressed behind 

 posterior marginal puncture. Elytra truncate-oval (12x7*5 mm. ), 

 widest behind middle, depressed on disc; sides lightly rounded; 

 lateral apical sinuosities wide, shallow; basal border raised at 

 humeral angles, but joining lateral border without interruption; 

 lateral border widely reflexed and carinate near base. Intercoxal 

 declivity of prosternum round and narrow in middle; of meso- 

 sternum deeply concave. Length 21, breadth 7"5 mm. 



Hab. — Vic. : Southern Gippsland (French). 



Allied to iV. crcesus, Casteln., but differing by its broader and 

 more depressed form; head larger; prothorax more transverse, 

 more ampliate at widest part, the spaces between the basal im- 

 pressions and the sides flatter; elytra of a much more coppery- 

 purple on the sides. The type specimen has the fifth interstice 

 of the elytra unipunctate. The male will probably prove to have 

 the interstices of the elytra more convex and the basal angles of 

 the prothorax more marked as in N. crif^suif. 



N'ote. — A specimen received from Mr. French, as from Victoria, 

 is of narrower and more elongate form (18-5 x 6 -5 mm); prothorax 

 much more strongly narrowed to base, with sides more strongly 

 sinuate; elytra of a steel blue colour with faint purple reflections, 

 head and prothorax with coppery reflections. It probably repre- 

 sents a closely allied, but distinct, species, but more specimens of 

 both forms than are before me would be required to pronounce a 

 confident opinion on this.
