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 
antenna pale testaceous, apical joints of antennae infuscate, 
abdominal segments edged with a paler colour. Above with 
rather sparse and not 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. 
J lab. — New South Wales: Inverell, Tweed River (Lea). 
Queensland : Brisbane (Mr. A. J. Coates). 
The character of the scutellum, distinctly 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. 
Hub.— Tamworth, N.S.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.
