the typical form. It seems too near iV. besti to be considered a 

 distinct species. 



J^ote (2). — A specimen {^), from the northern slopes of the 

 Buflfalo Mountain, near Porpunkah, is in my collection, which, 

 though closely resembling JV. besti, is perhaps a distinct species. 

 The differences I note are: — Colour brassy; prothorax more 

 rounded on sides, more strongly narrowed to base, basal angles a 

 little more marked, sides hardly subsinuate before base; basal 

 border of elytra joining lateral border without the slightest 

 interruption; mesosternum not concave between coxae. 



NOTONOMUS HOWITTI, n.Sp. 



9. Oval, robust. Head not large ; prothorax broader than 

 long, a little narrowed without sinuosity to base ; posterior 

 marginal puncture at basal angle outside lateral channel : elytra 

 strongly striate; humeral angles rounded; interstices depressed, 

 third 3-punctate, eighth wider than ninth. Black. 



Head convex (3 mm. across eyes); frontal impressions short, 

 distinct, divergent posteriorly; eyes convex, prominent, strongly 

 inclosed at base. Prothorax broader than long (3-5 x 4*2 mm.); 

 base and apex of equal width (3 mm.); sides lightly rounded, 

 meeting base in a gentle curve; base very lightly emarginate in 

 middle, almost truncate on each side (curving forward very 

 slightly to basal angles); basal angles well marked, obtuse; lateral 

 border narrow, thick, a little wider and more reflexed towards 

 base, passing round basal angles, thickened at basal angle to 

 receive posterior marginal puncture; median line lightly impressed; 

 lateral basal impressions deep, not elongate, space between them 

 rather depressed. Elytra oval (8*5 x 5 mm.), convex ; sides 

 rounded ; lateral apical sinuosities lightly marked ; basal and 

 lateral borders meeting at humeral angle without the slightest 

 interruption ; ninth stria and tenth interstice well developed. 

 Prosternum bordered along anterior margin; intercoxal declivity 

 rounded and narrowed in middle; mesosternum lightly concave 

 between coxae. Length 14, breadth 5 mm.
