Genus B r a c ii y d e m a, n.geii. 



Oval, compact. Head with two supraorbital setai on eacli 

 side. Mandibles with a seta in scrobe of outer side. Clypeus 

 unisetose on each side. Mentum with sinus oblique on sides: a 

 short, triangular, median prominence ; lobes pointed. Labial 

 palpi short; penultimate joint stout; apical joint thick at base, 

 compressed (a concavity on outer side), pointed at apex. Max- 

 illary palpi with two apical joints short; penultimate joint stout, 

 wide at apex, setigerous; apical joint triangular, pointed, a con- 

 cavity on lower side. Prothorax one-half wider at base than 

 at apex; two marginal setae on each side, posterior seta just 

 within basal angle. Elytra oval, bordered on base ; sutural 

 striole wanting ; third interstice bipunctate on disc ; eighth 

 shortly carinate towards apex; ninth obsolete and impunctate in

Though closely allied to Oopterus, a new genus is required for 

 the two small beetles described below, one from Victoria, the 

 other from Tasmania. Their compact, oval, Codes-like form is 

 very different from that of Oopferus. 



BrACHYDEMA TASMANIiE, n.sp. 



Oval, compact, piceous, nitid.

 rowed to apex (1 mm.), smooth; a feeble impression on base at 

 each side of peduncle; base truncate; Ijasal angles marked, 

 obtuse; lateral border narrow, extending along base on each side 

 to basal impressions; median line obsolescent. Elytra truncate- 

 oval, convex, substriate, wide across base; basal border slightly 

 raised above lateral border at humeral angles; first stria entire,
