288 REVISION OF THE GENUS NOTOXOMdS, 



metallic-cupreous margin, basal angles of prothorax a little more 

 obtuse; basal border of elytra not raised above lateral border at 

 humeral angles (in N. ausiralasice it is slightly raised above the 

 lateral border at point of junction); prosternum with intercoxal 

 declivity narrowed and rounded in middle; mesosternum decidedly 

 concave between cox£e. Length 15-5-16, breadth 5-8x6 mm. 



Hab.—N.S.W. : Hunter River (Froggatt). 



Two specimens (9) in my collection without exact locality 

 have the elytra as convex as in iV. austral asice, Dej., and these I 

 look upon as typical of the species. 



Var. N. luculentus. — I suggest this varietal name for a 

 form from the Blue Mountains which has the 9 with the 

 prothorax longer and more narrowed to the base ; elytra 

 more depressed, with lightly convex interstices; (J with elytra 

 depressed, interstices very convex. Length 13-5-16 mm. 

 Excepting for the bright cupreous margin of the elytra, N. 

 luculentus resembles the species I have named N. sydneyensis so 

 closely that I cannot indicate other differences, though I belie^■e 

 them to be two closely allied but distinct species. Length 

 13-5-16 mm.

NOTONOMUS SYDNEYENSIS, n.Sp. 



Oval, depressed. Head not large (2-8 mm. across eyes); pro- 

 thorax broader than long, not sinuate on sides before base; basal 

 angles obtuse : elytra truncate-oval, stronglj'^ striate; interstices 

 convex, strongly convex in ^, lightly so in 9, third 2-punctate, 

 eighth and ninth very convex : intercoxal declivity of prosternum 

 rounded; of mesosternum concave. Head black (sometimes with 

 faint seneous tinge), prothorax and elytra dark purple (sometimes 

 greenish); prothorax nitid; elytra rather nitid in $, subopaque 

 in 9; under surface black; tarsi and palpi piceous. 



Head convex; frontal impressions well marked. Prothorax 

 transverse (3-4 x 4*2 mm.); sides lightly rounded, a little more 

 obliquely narrowed to base than to apex; base (3 mm.) hardly 

 wider than apex (2-9 mm.), emarginate in middle, arcuate on
