324 EEVISION OF THE GENUS SOTONOMCS, 



middle, very lightly narrowed anteriorly, lightly and obliquely 

 (with short light prebasal sinuosity) narrowed posteriorly; apex 

 emarginate, anterior angles rather prominent, very close to head; 

 base (2-9 mm.) narrower than apex (3-1 mm.), hardly emarginate 

 in middle, curving forward on each side; border narrow, thick, 

 almost obsolete on sides of base; median line not deep, a subfovei- 

 form depression on its course between lateral basal impressions — 

 these oval, deep, wide at bottom; lateral basal spaces convex. 

 Elytra oval (8-5 x 4*8 mm.), widest about middle, narrowed to base, 

 lightly convex; lateral declivities not abrupt; lateral sinuosities 

 of apex strongly developed; basal border projecting strongly at 

 humeral angles,posterior margin raised and truncate; lateral border 

 narrow, thick, not reflexed on posterior part of sides; eighth stria 

 wide and deep; three inner interstices continuing to apex in full 

 width, third with two or three punctures on apical half, tenth 

 feebly and shortly developed near apex. Posterior femora com- 

 pressed, dilatate (slightly so in 9, strongl}' so in (J) on lower side 

 above apex of trochanters ; posterior tibiae slightl}^ arcuate ; 

 posterior tarsi thick, not long; joints much shorter than usual in 

 Notonomus. Length 13-16, breadth 4-3-5-2 mm. 

 ^«5._N.S.W. : Kiama (Sloane). 



An isolated species distinguished at once from all others of tlie 

 genus, except N. lesueuri, Casteln,, by its elongate metasternal 

 episterna. It is allied to N. lesueuri by all characters of a 

 generic nature, but is readily separated by its less cylindrical 

 shape, elytra strongly dentate at humeral angles, ttc. Six speci- 

 mens are before me, two of which have the third interstice of 

 each elytron 3-punctate ; this proves the presence of a third 

 puncture to be more than a mere accidental occurrence. The 

 eyes are more prominent in some specimens than in others. I 

 report this species as N. miles, Castelnau, on the authority of Mr. 

 Masters, who has informed me that his specimens so named were 

 received by him from Count de Castelnau. Chaiidoir evidently 

 overlooked the elongate mestasternal episterna when examining 

 N. miles.
