passing round angle on to base on each side; median line de- 

 cidedly marked; lateral basal impressions elongate, rather shallow; 

 lateral basal spaces widely and lightly convex; marginal channel 

 narrow. Elytra oval (10-6 x 5'7 mm.), lightly convex, lightly 

 rounded on sides, deeply striate; interstices convex, smooth (not 

 shagreened), eighth wider than ninth, tenth feebly developed; 

 lateral apical sinuosities light, wide; basal border strongly raised 

 and dentate at humeral angles; lateral border widely reflexed. 

 Intercoxal declivity of prosternum flat, of mesosternum hardly 

 concave. 



Q. With three setigerous punctures on each side of apical 

 ventral segment. Length, 19; breadth, 5*7 mm.

A single specimen occurred to me at the top of " The French- 

 man's Pinch," four miles north of Wood's Point, on the road 

 to Jamieson, December 27th, 1912. From N, eques Cast., it may 

 be readily distinguished by its narrower form; prothorax longer, 

 with narrower marginal channel ; elytra with interstices not 

 shagreened. It resembles N. phillipsi Cast., (as identified by me) 

 but differs by form more elongate; prothorax longer, narrower at 

 base, differently coloured, basal angles more strongly marked, 

 lateral basal spaces more convex; intercoxal declivity of pro- 

 sternum flat, of mesosternum hardly concave. 



The satrapus-group. 



Head large. Prothorax subcordate, wider at apex than at 

 base; basal angles obtuse; posterior marginal puncture in mar- 

 ginal channel (in N. satrapus considerably before basal angle, in 

 N. pluripunctatus at the obtuse basal angle). Elytra with basal 

 border not raised at humeral angles; interstices convex, third 

 and seventh bearing setigerous punctures (sometimes, also the 

 fifth), eighth wider than ninth at basal third. Intercoxal de- 

 clivity of prosternum narrow and rounded in middle. First joint 

 of four posterior tarsi with an external costa, the costa spinulose 

 on lower side. 



The satrapus- growp is evidently an ancient one, judging by the 

 setigerous punctures of the seventh interstice of the elytra. This
