148 tfOTES ON AUSTRALIAN COLEOPTERA. 



anterior angles obtuse, posterior rectangular, lateral border nar- 

 rowly horizontal, and separated from disc by a row of setiferous 

 punctures, disc with fine punctures irregularly and diffusely 

 placed. Scutellum arcuate-triangular, punctate. Elytra of same 

 width as and closely fitting prothorax, shoulders rectangular, 

 sides parallel to half-way, with a row of lateral seta?: rather 

 widely rounded behind ; seriate-punctate without a sign of 

 striation, the punctures in series, rather widely distant: intervals 

 each with a single row of even more widely placed punctures; 

 these more distant on outside intervals. Underside with large, 

 diffuse punctures. Tibiae straight, slender, little widened at, 

 and with a row of stout bristles near apex. Posterior tarsi with 

 claw-joint approximately as long as the rest combined. Dimen- 

 sions : 3x 1| mm. 



Hah. — Mount Wilson (Blue Mountains, N.S.W.). 



I took seven specimens in a rotten Eucalyptus log during 

 March of the present year (1919), and cannot find an existing 

 genus for their reception. The 3-jointed club of antenna?, slight 

 convexity of form, non-denticulate tibiae, and non-striate elytra 

 form a combination requiring a new generic status. 



Types in Coll. Carter. 



Bkachyciribk tasmanicum, n.sp. 



P. eddish-brown, very convex. 



Head coarsely, not closely punctate; joint 1 of antenna? very 

 stout, 2 intermediate in thickness between 1 and 3, 3-8 sub- 

 moniliform and closely packed, apical three forming a club, 9 

 and 10 strongly transverse and cupuliform, ] 1 round and large. 

 Prothorax bulbous, the narrow lateral border not seen from 

 above; base and apex truncate, sides evenly and rather widely 

 rounded, all angles very obtuse, disc coarsely and rather distantly 

 punctate. Scutellum small and bead-like. Elytra of the same 

 width at base and less than twice as long as the prothorax, with 

 about eight rows of foveate punctures on each elytron, placed in 

 sulci, the punctures almost contiguous; intervals convex; front 

 and mid tibia? finely spinose on the outside edge, hind tibia? 

 flattened and expanded at apex; underside deeply pitted with
