622 NEW AUSTRALIAN SPKCIES OP CAHABlb^, 



Anterior femora wide, lower side protuberant, and with an ante- 

 apical emargination; anterior tibiae with two long teeth and a 

 small tubercle externally; intermediate tibia; slender, with a 

 sharp external apical spur; posterior coxae and trochanters im- 

 punctate. Length, 22; breadth, 5*2 ram. 



Allied to N. i-ugulos7ini Macl., with the type of which I have 

 compared it, but differing by the clypeus declivous, and with a 

 lateral fovea on each side; prothorax less transverse, less rounded 

 on sides, especially behind anterior angles ; elytra similarly 

 emarginate at base, but with shoulders more sharply marked, 

 each elytron 2-punctate towards apex; anterior tibia? with a 

 small denticle above two large teeth. It somewhat resembles 

 i\^. elongatum Macl., but is very distinct by small size, lighter 

 form; eyes much less prominent; prothorax longer, more strongly 

 sinuate on each side of base; elytra more deeply emarginate at 

 base, humeral angles less strongly dentate, etc. From N. angus- 

 tatum SI,, it differs by small size, more cylindrical form; clypeus 

 not trisinuate, etc. 



Carenidium atrum, n.sp. 



Robust, elongate, convex. Labrum lightly emarginate; pro- 

 thorax cordate, convex, shortly lobate; elytra narrow, convex, 

 impunctate, bimucronate at apex ; anterior tibiae 2-dentate. 

 Black. 



Head large (6-7 mm. across eyes), smooth, convex ; frontal 

 sulci long, deep, divergent; clypeus with median part strongly 

 declivous, very lightly emarginate, intermediate angles sub- 

 prominent, obtuse; eyes prominent, deeply enclosed in orbits 

 posteriorly; two supraorbital punctures on each side. Prothorax 

 broader than long (65 x 7-7 mm.), declivous to base; sides 

 roundly curved, decidedly narrowed to apex, shortly ajid lightly 

 sinuate on each side of base; apex emarginate; anterior angles 

 subprominent, obtuse; base rounded; border narrow, thick, sub- 

 equal, hardly reflexed, obsolescent on basal lobe; basal area well 

 defined, lateral channel very narrow, impunctate. Elytra a 

 little narrower than prothorax (15 x 7*3 mm.), convex, widest 

 about middle, rounded on sides; base emarginate, deeply decli-
