with which it agrees in all the features mentioned above, but 

 differs by elytra not margined with green, basal border far less 

 strongly dentate at humeral angles, lateral sinuosities of ajDex 

 deeper. From iV. i^peiiceri, 81. (with which it also agrees in the 

 features mentioned as distinguishing it from N. muelleri), it 

 differs by want of a green elytral border; more depressed upper 

 surface; prothorax longer, less rounded on sides and at basal 

 angles; intercoxal declivity of prosternum not flat. 



NOTONOMUS PLANIPECTUS, n.sp. 



Elongate-oval, subparallel; head moderate (2-75 mm. across 

 eyes), eyes subprominent; prothorax nitid, transversely striolate 

 (the striolee faint and wavy), subquadrate, sides rounded, a little 

 narrowed to base, bas-al angles rectangular, posterior marginal 

 seta on inner side of marginal channel opposite basal angle; elytra 

 deeply striate, interstices strongly convex, third 2-punctate, sixth 

 not narrowed near base, eighth narrow, convex; humeral angles 

 dentate. Black. 



Head convex, wide across occiput and between eyes; front 

 strongly biimpressed, the impressions short, arcuate, sharply out- 

 turned before and behind; eyes convex, not prominent, strongly 

 inclosed behind; postocular part of orbits about as long as e3"e 

 and rising gradually from head. Prothorax broader than long 

 (4-25 X 4*8 mm.), widest about middle, wider across base(3-75mm.) 

 than across apex (3-3 mm), depressed posteriorly; sides lightly 

 rounded, not ampliate at widest part, lightly subsinuate just 

 before base; apex emarginate, anterior angles a little prominent 

 but obtuse, rather widely bordered; base lightly emarginate in 

 middle, truncate on each side; border widely reflexed on basal 

 two-thirds of sides, narrower towards apex, extending as a narrow 

 edge on each side of base to basal impressions; median line 

 strongly impressed, reaching base; lateral basal impressions deep, 

 narrow, parallel. Elytra truncate-oval (10 x 5*7 mm.), rather 

 depressed on disc, strongly declivous on sides and apex; sides 

 very lightly rounded; lateral apical sinuosities well developed; 

 basal border lightly curved on posterior margin, strongly raised
