312 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



Of the same size and shape as ^'. Coatesi, but much darker, with 

 longer pubescence, the scutellum smaller and much more trans- 

 verse, and with less distance between posterior femora. 



Sericoderus Hardcastlei, n.sp. 



Broad. Piceous-brown; prothorax (except an obscure mark at 

 apex) somewhat paler than elytra; metasternum piceous, somewhat 

 darker at the sides; muzzle p.nd abdominal segments dark 

 testaceous-red; legs and antennse testaceous, the latter slightly 

 infuscate towards apex. Elytra with moderately long greyish 

 pubescence, sparser on prothorax, abdominal segments more 

 densely clothed with shorter pubescence, longer and sparser on 

 metasternum. Prothorax sparsely and minutely, elytra more 

 densely and strongly punctate, metasternum minutely punctate. 



Prothorax bisinuate, broadly rounded in the middle of the base, 

 angles largely produced, acute. Scutellum transverse, semi- 

 circularly rounded. Elytra longer than wide, narrowing from 

 base to apex, each distinctly separately rounded. Femora not 

 very thick, distance between posterior about equal to their length. 

 Length 1^, width § mm.

Sericoderus basipennis, n.sjD. 



Broad. Reddish-testaceous; prothorax with a piceous mark at 

 apex, elytra rather more obscurely coloured than prothorax and 

 scutellum, the base more or less broadly clouded with black; head 

 (except muzzle), meso-, metasternum and basal segments of abdo- 

 men piceous-red; legs and antennae pale testaceous, the latter 

 slightly infuscate towards apex. Above equally densely clothed 

 with moderately long pubescence (shortest on prothorax), under- 

 surface with rather longer and sparser pubescence. Above very 

 minutely punctate (strongest on elytra), metasternum distinctly 

 punctate. 



Prothorax feebly depressed at base, bisinuate, angles largely 

 produced, acute. Scutellum broadly transverse, semicircularly
