 81oane. 



One specimen was found under a log in the thick Karri Forest, 

 14 miles south-westward from Manjimup, in January. Closely 

 allied to M. Icevicollis SI., but differing by form more robust and 

 convex; front more strongly biimpressed: eyes more convex; 

 prothorax more convex, especially near base; lateral basal im- 

 pressions feebly marked ; elytra more convex, more strongly 

 declivous to sides and apex, inner striae more decidedly marked, 

 more strongly punctate, deeper on apical declivity, interstices 

 convex on apical declivity. I have not been able to discern any 

 dorsal punctures on the third interstice of the elytra in m'y single 

 specimen. 



Mecyclothorax ovalis, n.sp. 



Oval, convex. Prothorax transverse, wider at base than apex, 

 not punctate near base; elytra fully striate, striae formed by rows 

 of punctures, these punctures reaching apex, eighth interstice 

 not carinate towards apex. Reddish-brown. 



Head wide, convex; front lightly biimpressed; eyes round, 

 convex. Prothorax transverse, convex, Isevigate, wide and smooth 

 across base; sides rounded; basal angles widely rounded; base 

 lightly sinuate on each side of peduncle; median line obsolete on 

 disc, marked near base; two marginal setigerous punctures on 

 each side, anterior a little before middle, posterior in marginal 

 channel a little before basal angle. Elytra oval, convex; humeral 

 angles rounded : striae well-marked, punctate ; interstices de- 

 pressed, narrow and convex near apex, eighth not carinate near 

 apex. Length, 3*2; breadth, l"6mm. 



Hab. — W.A. : Manjimup (Sloane). Type in Coll. Sloane. 



I found one specimen of this distinct species beneath a log, 

 near the township of Manjimup, in the heavy, south-western 

 forest of Western Australia. It differs much from all others by 

 its colour; robust, convex form; wide prothorax (not much nar- 

 rower than elytra), without any basal puncturation, sides strongly 

 rounded; elytra oval, convex, strongly punctate-striate, striae 

 well marked near apex, the puncturation continuous to apex, 

 though becoming finer on apical declivity.
