bY T G. SLOAkE. 61 1 



a little wider anteriorly, wide at posterior angles: median line 

 strongly impressed; one marginal setigerous puncture on each 

 side at posterior angle. Elytra not wider than prothorax(9-3 x 

 6-9 mm.), convex, lightly rounded on sides; base widely truncate- 

 emarginate, strongly declivous, a few punctures on each side; 

 border reflexed, erect at humeral angles: margin wide, especially 

 on apical curve; a catenulate row^ of evenly and rather closely 

 placed punctiares along sides. Prosternum with intercoxal part 

 wide, lightly concave, two or three punctures on each side. Legs 

 rather light; anterior tibia? 3-dentate; intermediate tibiae not 

 dentate at apex on outer side. Length, 18-5; breadth, 7 mm. 

 }lab. — South Australia : Nullabor Plain. Type in Coll. Sloane. 

 Two specimens were given to me by Mr. C. French. The 

 position of this species is in the C sm.aragdnh(m-<;rovp beside 

 C. interiore SI.; it can be readily distinguished from the latter 

 by size smaller: prothorax less quadrangularly transverse, pos- 

 terior angles more obtuse, far less marked, base much more 

 strongly lobate; elytra with humeral angles far more strongly 

 marked and erect. The position of the posterior marginal 

 setigerous puncture at the posterior angle will in itself differ- 

 entiate it from C. emarginatnm SI., in which this puncture is 

 considerably before the posterior angle. 



Carenum virescens si., var. viridiventkis, n.var. 



Robust, convex. Head with one supraorbital puncture on 

 each side. Prothorax transverse (3-8 x 6*6 mm.), rounded at 

 posterior angles, lobate; two marginal punctures on eachsid*. 

 Elytra oval, bipunctate. Anterior tibiae 3-dentate. Green, nitid; 

 legs, middle of prosternum, metasternum, and abdomen, also 

 anterior parts of head, mandibles, and apical ventral segment 

 black; disc of prothorax more or less atrous. Length, 17-8-20; 

 breadth, 6 8-7 '7 mm. 



Hab. — W.A. : Cue, Kalgoorlie, Lake Darlot. Type in Coll. 

 Sloane. 



This form differs from the typical C virescens by elytra wholly 

 green; ventral segments, excepting apical, viridescent.
