(and the elytra narrowly at apex) yellowish-red; sterna 
black. 
"Head transversely and obliquely finely wrinkled ; median 
line distinct. Prothorax strigose in middle, becoming at 
sides very densely and finely corrugated; punctate only in 
middle; basal lobe notched. Elytra seriate—towards sides 
striate-punctate; interstices not visibly punctate. Length 
2$mm. 
a Karridale, Bunbury, Swan River. 
The abdomen is sometimes wholly black, except for @ 
narrow border; sometimes the black forms a subquadrate 
basal patch of the three first segments, in several specimens 
the red is continued to flanks of metasternum. The species 
differs from apiciflavus in being much shorter, with less 
parallel sides, not tinged with green, by the corrugations at 
sides of prothorax, &c. In colour (except as to being 
coppery) it agrees with the description of /evigatus, but that 
species is said to have the prothorax impunctate. 
DITROPIDUS NIGRIPENNI S, D.sp. 
Oblong-ovate ; pale reddish-testaceous; elytra black, with 
a slight bluish gloss, the extreme apex and margins very 
feebly diluted with red; apical joints of antenne infuscate. 
Head feebly wrinkled; median line scarcely traceable- 
Prothorax impunctate; basal lobe entire. LElytra seriate, 
sides striate-punctate; interstices impunctate. Length 
24-3mm. 
Hab.—N.S.W.: Galston (Dumbrell and Lea), Tamworth 
(Lea). 
The dark elytra, in striking contrast to the rest of the 
body, should render this species peculiarly distinct. At a 
glance it is not unlike Pascoe, but that species has part of 
the under-surface dark. 
DirTropipus ELUTUS, N.sp. 
Oblong-ovate. | Head and prothorax red; elytra black, 
each diluted with red in middle; mouth-parts, antenne, and 
Jegs testaceous; sterna and abdomen black. 
Head rather sparsely and finely punctate; median line 
indistinct. Prothorax almost invisibly punctate; basal lobe 
feebly notched. Elytral seriate-punctate, punctures very 
distinct ; sides deeply striate. Length 24mm. 
Hab.—N.8.W.: Forest Reefs. 
Apparently not very close to any species hitherto de- 
scribed,
