I received this fine species from Mr. H. W. Brown, vlio dis- 

 covered it, with other new species, at Anketell, 70 miles south- 

 west of Cue. 



It can be compared only with C. emargiiiafum SI., var. feqtcalis 

 SI., with whicl) it forms a separate group in the genus Careitum, 

 distinguished by liaving the posterior marginal seta situated 

 considerably before the posterior angle. I cannot compare it 

 with C . emarffinahim SI., but from its v ar . reqiiali s SI., also found 

 by Mr. Brown at Anketell, it differs by head more narrowed 

 behind eyes, frontal sulci strongly- divergent, eyes more pro- 

 minent; prothorax less convex, less declivous to sides, more 

 widely margined, three marginal sette on each side: elvtra with 

 sides of base not bordered, etc. 



Carenum emarginatum si., var. ^equalis, n.var. 



Elliptical-oval, subparallel, Isevigate. Head with frontal sulci 

 short, subparallel, one supraorbital seta on each side. Black, 

 prothorax and elytra with a faint purple tinge in lateral channels. 



Prothorax transverse (54 x 8"6 mm.), lobate, of equal width 

 (6'8 mm.) at base and apex; anterior angles lightly prominent; 

 posterior angles rounded; border widely reilexed, especially at 

 posterior angles; lateral channel wide, bipunctate, the posterior 

 puncture considerably before basal angle. Elytra truncate-oval 

 (14 X 875 mm.), bipunctate above apical declivity: humeral angles 

 prominent, obtuse; border retlexed, stiongly upturned and folded 

 back at humeral angles, continued along sides of base. Anterior 

 tibiae 3-dentate; posterior coxse and trochanters bearing a seti- 

 gerous puncture. Length, 22-28; breadth, 7-8-10 mm. 



Hab. — W.A. : Anketell (Brown). Types in Coll. Sloane. 



Closely allied to C. emarginatum SI., the tj'pe of which is in 

 Coll. French, at the National Museum, Melbourne, and with 

 which I am not now able to compare it. Judging from the de- 

 scription of C. etnarginattiin, the form found by Mr. Brown at 

 Anketell offers the following evident differences :- form more 

 elongate; elytra not more emarginate than usual in the genus: 

 I believe, too, that the posterior angles of the prothorax are less
