sharply to head. Prothorax broader than long (5-3 x 6 mm.), 

 convex, not depressed along middle of base, a little narrower 

 (3-9 mm.) at base than at apex (4*2 ram.); sides strongly rounded, 

 hardly more gently posteriori}" than anteriorly; apex truncate: 

 anterior angles not marked, close to head; base roundly truncate; 

 basal angles not marked; border narrow, thick, a little wider 

 towards base; posterior marginal puncture on margin at basal 

 angle; median line light; lateral basal impressions wide, short. 

 Elytra oval (1-i x 7-8 mm.), convex; sides rounded; lateral apical 

 sinuosities light, wide; basal border joining lateral border at 

 shoulders without the slightest interruption ; lateral border 

 narrow; lateral channel giving off a ninth stria, and so forming 

 a well developed tenth interstice on posterior half of elytra. 

 Length 23, breadth 7-8 mm.

Closely allied to and resembling N". gippsiensis, Casteln., but 

 more convex and differing by having the prothorax more strongly 

 and evenly rounded on the sides, the basal angles quite rounded 

 off, the posterior marginal puncture placed on the border, &c. 

 This is the species which Mr. Rainbow described as iV. montamcs, 

 but as that name was used in the genus Notonomus by Castelnau 

 it is necessary to change it, even although Castelnau's name has 

 sunk to the rank of a synonym.

 Prothorax subdepressed, subcordate (5-8 x 6*8 mm.) ; base and 

 apex of equal width (4*8 mm.); sides rounded, lightly narrowed 

 to base; basal angles obtuse; posterior marginal puncture placed
