604 STUDIES IX AUSTRALIAN ENTOMOLOGY, NO. XII., 



posterior angles obtuse, posterior marginal puncture distant from 

 basal angle; elytra strongl}^ striate, interstices convex, third 5- 

 to 7-punctate, tenth well developed, narrow, not long. Black, 

 nitid; prothorax sometimes with a faint greenish tinge on sides 

 near lateral basal impressions; legs, antenna? and mouth-parts 

 piceous-red. 



Head small (3*2 mm. across eyes); front lightly and widely 

 biimpressed; eyes enclosed in strongly developed orbits, so that 

 the head appears somewhat constricted behind them. Prothorax 

 broader than long (4--1 x 4-8 mm.), depressed in middle and 

 posterior parts of disc, declivous to anterior angles; sides very 

 lightly and evenly rounded on anterior two-thirds, obliquely and 

 lightly narrowed to base: basal angles obtuse, but well marked; 

 base truncate, widely subsinuate in middle, very lightly rounded 

 on each side; posterior marginal puncture on inner side of lateral 

 channel, a little before basal angle; border wide and strongly 

 refiexed on posterior half, continuing round basal angles on to 

 base on each side; median line finely but strongly impressed; 

 lateral basal impressions of moderate length, narrow, not deep, not 

 reaching base in full depth. Elytra truncate-oval ( 102 x 5 -9 mm.), 

 lightly convex, subparallel on sides; lateral sinuosities of apex 

 rather strongly developed; basal border lightly raised at humeral 

 angles to form an obtuse stout prominence, posterior margin 

 hardly rounded; lateral border widely refiexed near base. Inter- 

 coxal declivity of prosternum rounded; of mesosternum concave. 

 Posterior femora with lower side strongly dilatate above apex of 

 trochanters ; tarsi with upper surface (excepting basal joint) 

 longitudinally striolate, fifth joint glabrous beneath. Length 

 16-5-18, breadth 5-6-G-15 mm.

In general appearance resembling N. mneJJeri, SI., but differing 

 decidedly by elytra with lateral border widel}^ refiexed near the 

 humeral angles which are subdentate, interstices more convex; 

 posterior femora strongly dilatate on lower side above trochanters, 

 tarsi with upjDer surface striolate. It is allied to X. froggatti, SI.,
