Sericoderus minutus, n.sp. 
Broad. Testaceous; pro thorax more clear than elytra, and 
with a piceous mark at its apex; undersurface somewhat darker 
than above; legs, muzzle and base of anteume pale testaceous, 
rest of antenme brown; abdominal segments slightly paler towards 
apex. Elytra with moderately long pubescence, slightly sparser 
on prothorax, undersurface densely clothed with rather short 
pubescence. Prothorax microscopically, elytra densely and min- 
utely, underneath visibly punctate. 
Prothorax with the base widely rounded, angles largely pro- 
duced, acute. Scutellum slightly transverse, semicircularly 
triangular. Elytra at the base almost as wide as long, apex 
almost conjointly rounded. Femora somewhat thickened, distance 
between posterior greater than their length. Length §, width 
|- mm. (vix).

Sericoderus compactus, n.sp. 
Very broad. Piceous, prothorax (except at apex, which is 
dark dull red) indistinctly lighter than elytra; muzzle, legs and 
antenme pale testaceous. Above equally clothed with rather 
short greyish pubescence, undersurface more sparsely. Above 
with minute punctures, densest on elytra; metasternum minutely 
punctate. 
Prothorax feebly depressed at base, bisinuate, angles largely 
produced, acute. Scutellum small, broadly transverse, semi- 
circularly rounded. Elytra as wide as long, narrower than pro- 
thorax, narrowing from base to almost extreme apex, each feebly 
separately rounded. Femora moderate, distance between posterior 
less or equal to their length. Length §, width f mm. 
Hab. — Clarence River, N.S.W. 
Differs from the preceding in being darker, broader, with a
