NEW SPECIES OF AUSTRALIAN COLEOPTERA, 
Of the same size and shape as S. 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 and abdominal segments dark 
testaceous-red; legs and antennae 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 J, width § mm. 
I lab. — Sydney, Inverell, Forest Reefs, Tarn worth (Lea); Armi- 
dale (Mr. D. McDonald); Hillgrove (Dr. C. Hardcastle). 
Sericoderus basipennis, n.sp. 
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
