interrupted at point of junction with lateral border; third inter- 

 stice with three or four punctures, eighth wider than ninth towards 

 base. Four posterior tarsi without spinules beneath costa of exter- 

 nal side of first joint; hind tarsi short, first joint not as long as 

 the two succeeding joints together.

78. NOTONOMUS CYLINDRICUS, n.sp. 



£. Elongate, subcylindrical. Head large; prothorax subcordate; 

 basal angles rounded; posterior marginal puncture on border at 

 basal angles; elytra parallel, convex, strongly striate; humeral 

 angles edentate; third interstice 4- or 5-punctate. Black. 



Head convex (3-8 mm. across eyes) ; frontal impressions obsolete; 

 clypeus bi-impressed ; eyes with orbits reniform; postocular part 

 of orbits well developed. Prothorax broader than long (4'5 x 4-9 

 mm.), widest before middle, convex; sides slightly rounded, round- 

 ly, obliquely narrowed to base; apex (3-9 mm.) wider than base 

 (3-5 mm.) ; anterior angles not marked; basal angles obtuse; bor- 

 der well developed posteriorly, passing round basal angle to 

 lateral basal impression on each side; lateral basal impressions 

 deep, short ; lateral basal spaces convex. Elytra much wider than 

 prothorax (10-8 x 6*2mm.), very convex; lateral apical sinuosities 

 well developed ; interstices lightly convex, eighth a little wider than 

 ninth towards base, tenth hardly indicated. Intercoxal declivity 

 of prosternum wide, rounded, of mesosternum concave; metepi- 

 sterna short. Four posterior tarsi with first joint costate on exter- 

 nal side, without spinules below costa; hind tarsi with first joint 

 shorter than two succeeding joints together; fifth joint setulose 

 beneath. Length 18, breadth 6-2 mm.
