292 REVISION OF THE GENUS NOTOXOMUS, 



(3-2 mm.), truncate in middle, curving decided!)'- forward on each 

 side; basal angles very obtuse, hardly marked; border thick, very 

 narrow anteriorly, wider towards base; median line lightly im- 

 pressed ; lateral basal impressions wide, short, deep. Elytra 

 narrow ((S-5 x 4*8 mm.), convex; sides very lightly rounded; lateral 

 sinuosities of apex light; scutellar striole ver}'- short; basal border 

 truncate on posterior margin, obtuse and hardly the least raised 

 above the narrow lateral border at their point of junction; ninth 

 interstice very narrow, interrupted on inner margin by umbilicate 

 punctures; tenth interstice long, convex, extending forward to 

 basal third. Tntercoxal declivity of prosternum flat; of meso- 

 sternum widely and lightly concave. Length 13-17, breadth 

 4-5-5-5 mm.

It probably comes nearest to iV. incrassatus, Chaud., amongst 

 described species, but differs by prothorax with basal angles 

 widely obtuse; lateral basal impressions deeper, wider, more oval; 

 elytra with interstices hardly convex, humeral angles not marked, 

 &c. From N. austi^alasice, Dej., it differs by its form narrower 

 and more convex; head smaller; prothorax shorter, less narrowed 

 to base, sides more rounded to apex and base, posterior angles 

 less marked, lateral basal impressions shorter and wider; elytra 

 less deeply striate, interstices flatter, eighth and ninth narrower, 

 humeral angles not marked, tkc. It may be distinguished from 

 N. lateralis, SI., by prothorax more transverse, with lateral channel 

 wider,lateral basal impressions deeper and wider, basal angles 

 more widely rounded; elytra with third interstice bipunctate (the 

 posterior puncture further from apex), eighth interstice narrower, 

 &c.

One of my original type specimens (9) is before me; it has the 

 intercoxal declivity of the prosternum narrowed and a little 

 rounded in middle, of the mesosternum decidedl}^ concave; elytra
