vous; apical mucro of each elytron thick, conical, a little up- 

 turned, points distant from apical margin ; border narrow, 

 thickened posteriorly; four punctures in a single row on base of 

 each elytron. Posterior coxae and trochanters, and ventral seg- 

 ments impunctate. Length, 29; breadth, 7'3mm. 



Uab. — W.A. : Anketell (Brown). Type in Coll. Sloane. 



A thoroughly distinct species, characterised by its elongate, 

 but robust, convex form, black colour, and mucronate elytra. The 

 short, thick, pointed mucrones, distant from the apical margin, 

 seem to indicate that the type-specimen is the (J; I should expect 

 the 9 to have narrower and more pointed mucrones placed near 

 the apical margin, as is the case with C. leai SI. 



Carenidium bifurcum, n.sp. 



Elongate, depressed, Isevigate. Head with two supraorbital 

 punctures on each side, labrura deeply emarginate; prothorax 

 strongly lobed, two marginal punctures on each side; elytra 

 narrow, impunctate, two elongate sharp horns at apex, disc 

 flattened, slightly concave towards base, border not dentate at 

 humeral angles; anterior tibijie 2-dentate. Black; prothoi'ax and 

 elytra widely margined with green, inHexed margins of elytra 

 green inwai'dly. 



Head smooth, large (6'4mm. across eyes), sub-depressed; 

 mandibles with upper surface flattened towai'ds base; frontal 

 sulci long, deep, diverging backwards; clypeus with median part 

 widely arcuate emarginate, intermediate angles prominent; pre- 

 ocular process narrow; preocular sulcus well marked; eyes pro- 

 minent, convex, enclosed behind, postocular parts of orbits not 

 as prominent as eyes, strongly and obliquely narrowed behind. 

 Prothorax broader than long (5-7 x 7-3 mm.), widest just before 

 posterior marginal seta, sub-depressed, hardly declivous to basal 

 area in middle, strongly rounded at posterior angles, strongly 

 sinuate on each side of basal lobe (this more developed than 

 usual); anterior margin truncate; anterior angles lightly ad- 

 vanced, widely obtuse; border wide (particularly behind anterior 

 and posterior angles); median line strongly impressed; basal area 

 defined by a strong transverse impression. Elytra narrower
