314 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 antennae 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. Scutelhim 

 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 antennse 

 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.
