310 EEVISION OF THE GENUS NOTOyOMUS, 



Elliptical, upper surface depressed. Head and prothorax black, 

 nitid; elytra violaceous, with sutural interstices dark. Head not 

 large (2*8 mm. across ej^es); eyes convex, prominent. Prothorax 

 broader than long (3-4x4 mm.), truncate-cordate, subdepressed; 

 sides sinuate posteriorly; basal angles rectangular; base (3'1 mm.) 

 hardly wider than apex (3 mm.); border narrow anteriorly, widely 

 reflexed towards base, extending on sides of base to lateral 

 impressions; posterior marginal puncture at basal angle on an 

 internal dilatation of border; lateral basal impressions long, 

 parallel; lateral basal spaces almost flat. Elytra truncate-oval 

 (8 "2 X 5 mm.), depressed on disc, strongly declivous to apex, deeply 

 striate; interstices lightly convex, third 3-punctate, eighth and 

 ninth convex, eighth wider than ninth on basal half; basal border 

 hardly raised above lateral border at point of junction. Inter- 

 coxal declivity of prosternum wide, flat; of mesosternum wide, 

 vertical, hardly at all concave. Length 14*5, breadth 5 mm. 



Hah. — Victoria (W. Kershaw). 



Judging by the synonymy given above (on the authority of 

 Chaudoir) N. dyscoloides is a very variable species. I take the 

 form on which my description is founded to be Feronia semivio- 

 lacea, Casteln., and I should have thought F. victories from des- 

 cription to have been synonymous Avith iV^. sphodroides, Dej. I 

 have not seen Motschulsky's description, but have identified the 

 species from Castelnau's diagnoses and Chaudoir's note.

I have not identified this species. The following is a translation 

 of the too brief description : — Length 12-5 mm. It much 

 resembles A^. dyscoloides in facies, but is differently coloured. Of 

 a very brilliant black as if polished; elytra coppery, with the 

 margin black; e3''es more prominent; elytra a little less oval, more 

 declivous to tlie apex, more strongly striate; interstices more 

 convex, with thrr.e ov four large punctures on the third. 



Hah. — Southern Australia.
