Head small (2-6 mm. across eyes), convex ; eyes prominent. 

 Prothorax hardly broader than long (3-6 x 3*7 mm.), widest before 

 middle; base and apex narrow, of equal width (2-6 mm.); sides 

 lightly rounded anteriorly, decidedly and obliquely narrowed to 

 base ; anterior angles close to head ; base lightl}' and widely 

 emarginate in middle, truncate on each side; basal angles sharply 

 marked, almost rectangular; posterior marginal puncture at basal 

 angles in lateral channel; lateral basal impressions elongate; lateral 

 border fine, narrow, obsoletely subsinuate just before basal angles. 

 Elytra truncate-oval (8-2x5 mm.), widest behind middle, a little 

 narrowed to base; lateral apical sinuosities well developed, wide; 

 basal border with posterior margin evenly and lightly arcuate; 

 humeral angles lightly raised (not dentiform) at point of junction 

 of basal and lateral borders; strise deep; interstices convex, 

 third 4-punctate, eighth wide and depressed on basal half, ninth 

 with umbilicate punctures wide apart on sides, tenth very short,

N. bassi differs from N. gippslanclicus (as identified by me) by 

 colour; facies less elongate, less parallel, less convex; prothorax 

 more ampliate at widest part, with basal angles more sharply 

 marked; elytra with basal border more raised above the lateral 

 border at point of junction, and with the inner humeral angle 

 acute and far more sharply marked. 



One of my Yarragon specimens {$) has the prothorax evidently 

 wider (3*7 x 4 mm.), with base wider (2-9 mm.) than apex (2 8 mm.), 

 but presents no other differences from the description given 

 above.
