locate ill middle, a light sinuosity on each side of lobe ; border 

 reflexed, a little wider at posterior angles, narrow and obsoletely 

 emarginate on basal lobe ; marginal channel narrow along sides, 

 wider at posterior angles, not crossing basal lobe ; median line 

 strongly impressed ; no trace of the usual marginal punctures. 

 Elytra oval, hardly as wide as prothorax (10*25 x 6*5 mm.), 

 convex ; shoulders and base rounded ; base roundly declivous to 

 peduncle ; apex widely rounded ; lateral margin wide behind 

 shoulders ; border hardly reflexed, ending at shoulders in a very 

 short upturned projection ; two or three punctures on base of each 

 elytron ; a row of umbilical punctures along lateral margins ; a 

 strong puncture on each elytron, placed at about the middle of the 

 width, just before the posterior declivity ; suture stron^jly im- 

 pressed. Prosternum widely channelled between the coxse, two or 

 three punctures on each side near inner margin of coxse. Anterior 

 tibiae narrow, tridentate, a short prominent triangular tooth above 

 the three large ones ; inferior ridge serrate, a strong tooth project- 

 ing downwards from apex' of apical plate; intermediate tibiae 

 ciliate, without an external spur at apex. 



Length 19, breadth 6'6 mm. 



Hab. — Interior of South Australia. 



The affinity of this species is to C. rugatum^ Blkb., (naturally 

 a smooth shining species variable in colour, being sometimes of a 

 beautiful steel-blue), from which, however, it differs in colour and 

 in the shape of the prothorax and elytra ; — in C. rugatum the 

 posterior angles of the prothorax are not so much rounded off" and 

 the sinuosity on each side of the basal lobe is far more strongly 

 marked, and the elytra are wider and truncate at the base. 



Given to me by C. French, Esq., as coming from the interior of 

 South Australia. A second specimen, larger than the one described 

 above, is in his collection. 



Carenum virescexs, n.sp. 



(^. Robust, convex ; prothorax transverse, rounded at posterior 

 angles ; elytra broadly oval, bipunctate, inflexed margin wide ; 

 anterior tibiae tridentate.
