NOTONOMUS TRUNCATUS, n.Sp, 



Elliptical-oval, convex; prothorax rounded on sides, angles not 

 marked, posterior marginal seta before basal angle, not on border; 

 elytra oval, fully striate, interstices depressed, third 3-punctate, 

 eighth and ninth subeipial on basal half, basal border not raised 

 above lateral border at humeral angles, apex truncate; hind tarsi 

 elongate, narrow. Black. 



Head convex (3 '5 mm. across eyes). Prothorax broader than 

 long (4 X i'b mm.), convex, a little naiTOwer at base (3 mm.) than 

 apex (3*5 mm.), hevigate; sides rounded; anterior angles close to 

 head; basal angles obtuse; lateral marginal channel not defined 

 near base; lateral basal impressions short, wide; lateral border 

 narrow. Elytra oval (10 x 5"8 mm.) ; lateral apical sinuosities 

 well developed; strife decided, less strongly impressed in 9 than 

 in (J; interstices depressed on disc, eighth depressed, rather 

 nari-ow, hardly as wide as ninth on basal half, tenth moderately 

 developed, extending forward from apical sinuosity for one-third 

 the distance to base of elytra. Tntercoxal declivity of prosternum 

 wide, rounded; of mesosternum, concave. Four posterior tarsi
