NEW SPECIES OF AUSTRALIAN COLEOPTERA, 
Almost of the same bright colour as the preceding species, but 
without a trace of darker colour on prothorax or elytra. 
Sericoderus politus, n.sp. 
Very broad, moderately convex, highly polished. Dark piceous- 
brown; muzzle, legs and base of antennas clouded-testaceous; 
anterior legs paler than four posterior. Above glabrous, under- 
surface moderately densely clothed with greyish pubescence. 
Above densely, extremely minutely and shallowly punctate; under- 
surface densely and minutely punctate, or very feebly transversely 
strigose. 
Prothorax feebly bisinuate, angles produced, acute. Scutellum 
feebly transverse, semicircularly triangular. Elytra slightly wider 
than long, widest behind the base, slightly wider than prothorax, 
each separately rounded. Legs rather slender, distance between 
posterior femora less than their length. Length -|, width -| mm. 
Bab.— Windsor, N.S.W. 
The convex form, glabrous upper surface and dark colour of 
this species will serve to distinguish it; the head is easily with- 
drawn from the prothorax. I have numerous specimens, but am 
not quite certain as to whether I have referred this species to its 
correct genus, or whether a new one should be formed for its 
reception. 
Clypeaster collaris, n.sp. 
Moderately elongate. Reddish-testaceous; prothorax with a 
small piceous mark at apex, on each side of which is an indistinct 
pale testaceous marking, narrowly margined with piceous at base; 
head — except muzzle — blackish-brown; undersurface — except 
abdominal segments — darker than above, legs and antennas 
testaceous. Above equally clothed with rather short and dense 
pubescence, undersurface rather sparsely pubescent. Above 
equally densely and not very minutely punctate, undersurface 
rather more feebly; underside of head minutely transversely 
strigose. 
Prothorax feebly depressed at base, feebly bisinuate, angles 
not at all produced. Scutellum small, transversely triangular.
