impressions deep, narrow, parallel. Elytra narrow, truncate-oval 

 (10 X 6 mm.), depressed; sides lightly and evenly rounded, lateral 

 apical sinuosities well developed; basal border raised and forming 

 a strong obtuse projection at humeral angles; lateral border wide, 

 reflexed, narrow just behind humeral angles; interstices sharply 

 raised, seventh wider, more convex than others and forming 

 lateral margin of disc, eighth and ninth narrow, convex, tenth 

 well developed in front of lateral sinuosities. Intercoxal declivity 

 of prosternum flat; of mesosternum hardly at all concave; meta- 

 sternum longitudinally channelled in middle from base to apex. 

 Lateral parts of abdomen and episterna of metasternum rugulose- 

 punctulate. Length 18, breadth 6 mm.

A distinct species ; it is perhaps nearest to N'. angustihasis, 

 Sloane, but dijffers decidedly by pro thorax less narrowed and 

 more shortly sinuate posteriorly, posterior marginal puncture at 

 the basal angle; elytra flatter, interstices more strongly convex, 

 ninth narrower; posterior femora wider and more dilate in middle.

Unknown to me. If it has the intercoxal declivity of the pro- 

 sternum flat its position would seem to be near N. liragp.rus, SI.; 

 if rounded, it would come near .V. kingi, Chaud., but this does 

 not appear to me likely to be its place. From Chaudoir's original 

 description and the note in his 'Supplement ' I select the following 

 characters as diagnostic of iV. sahiridescens : — Compared with N. 

 mneomicam — prothorax scarcely shorter than the breadth; upper 

 surface more convex; lateral margin evidently finer and narrower 

 anteriorly, and forming on the contrary a wider border as it 

 approaches the posterior angles : elytral interstices more convex 

 — particularly towards the apex — eighth and ninth decidedly 

 narrower throughout their whole length; third bipunctate. 

 Colour black. Length 23 mm.
