310 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



Sericoderus Coatesi, n.sp. 



Broad. Testaceous; prothorax more clear than elytra, and 

 with a piceous mark at its apex; metasternum and basal segments 

 of abdomen darker than above; legs, muzzle, palpi and base of 

 antennae pale testaceous, apical joints of antennsie infuscate, 

 abdominal segments edged with a paler colour. Above with 

 rather sparse and njot very long pubescence, sparsest and shortest 

 on prothorax; undersurface rather more finely and densely pubes- 

 cent. Prothorax microscopically, elytra densely and minutely 

 punctate; undersurface indistinctly punctate. 



Prothorax very feebly bisinuate at base, angles produced, acute. 

 Scutellum as long as wide, semicircularly rounded. Elytra 

 slightly longer than wide, each feebly separately rounded. Femora 

 moderately thickened, distance between the posterior greater than 

 their length. Length ^, width 4 (vix) mm. 



//ab. — New South Wales: Inverell, Tweed River (Lea). 

 Queensland : Brisbane (Mr. A. J. Coates). 



The character of the scutellum, distinctl}^ as long as wide, will 

 separate this species from either of the preceding. 



Sericoderus obesus, n.sp. 



Broad. Testaceous; elytra narrowly at base, prothorax narrowly 

 at base and a small mark in front, piceous-black; undersurface 

 darker than above; legs and base of antennae pale testaceous, 

 apical joints slightly darker. All over with moderately long 

 pubescence, sparsest on prothorax and head. Above minutely, 

 undersurface indistinctly punctate. 



Prothorax with the base feebly rounded in the middle, angles 

 produced and acute. Scutellum transversely triangular. Elytra 

 wider than base, where they are wider than long, apex truncate. 

 Femora thick. Length 1, width | mm. 



//a6.— Tamworth, KS.W. 



Differs from the preceding, which it strongly resembles, in 

 being slightly larger and broader, angles of prothorax more 

 strongly produced, scutellum slightly different, and by the dark 

 marking of the suture of prothorax and elytra.
