73. Notonomus apicalis, n.sp. 



Elongate-oval, rather depressed. Prothorax truncate-cordate; 

 basal angles rectangular; elytra on disc feebly, at apex strongly 

 striate; third interstice 2-punctate; humeral angles subdentate. 

 Nitid; head, prothorax, and underparts black; elytra aeneo-cupre- 

 ous, margin black. 



Head 2'4 mm. across eyes. Prothorax broader than long (3 x 

 3-5 mm.) ; base and apex of equal width (2-5 mm.) ; sides lightly 

 rounded, shortly subsinuate just before base; border strongly 

 reflexed posteriorly, continued on to base ; posterior marginal 

 puncture on border at basal angle; lateral basal impressions 

 elongate; lateral basal spaces depressed. Elytra oval (7*2x4-3 

 mm.); basal border obtusely raised above lateral border at humeral 

 angles; lateral apical sinuosities well developed; striae lightly or 

 faintly impressed on disc, more distinct near base, strongly im- 

 pressed on apical declivity; first well marked for whole length, 

 4-8 obsolete or faintly impressed; interstices flat, except just near 

 apex. Intercoxal declivity of prosternum fiat, of mesosternum 

 not concave. Four posterior tarsi with external side costate, and 

 spinulose beneath costa. Length 12, breadth 413 mm.

I have to thank Mr. J. A. Kershaw for the opportunity of 

 describing this species. It is allied to N. dyscoloides Motsch., 

 though it has a superficial resemblance to the species of the chaly- 

 beits-group. The flat intercoxal declivity of the prosternum, and 

 the elytra strongly striate on the apical declivity, where the inter- 

 stices are raised, indicate its affinities, and preclude it from being 

 placed in the chalyb eus-gv oup. 



The later alis-groiip. 

 Prothorax with posterior marginal puncture on border at basal 

 angle; lateral basal impressions short, not reaching margin of 

 base. Elytra strongly striate; basal border not, or very
