9th-10th combined; corrugate at the sides; foveas of imdersurface 
almost connected. Prothorax decidedly longer than wide, at its 
widest the width of the head (excluding eyes); angles rounded, a 
distinct and rather wide transverse impression at base, none at apex; 
base narrowly margined. Elytra strongly dilating towards apex, 
where the width is not much less than their length, each almost 
obliquely truncate. Length to apex of elytra 2, of abdomen 3; 
width 4 mm. 
Hab. — Sydney. 
A small species, which should be easily recognised by the 
carinate head. 
Carphurus impunctatus, n.sp. 
(^). Elongate, subparallel, shining, strongly depressed. Head 
and prothorax reddish, with obscure brownish blotches — in the 
former towards the sides, in the latter on apical half; antennae 
reddish, apical third infuscate; elytra black, the basal fourth 
testaceous, the two colours distinctly separated; abdomen black, 
base and margins of the second segments reddish; legs brownish- 
black, tarsi testaceous; undersurface of coxae, of anterior portion 
of intermediate, and base of posterior femora, diluted with testa- 
ceous. Sparsely clothed with not very long blackish hair, under- 
surface almost glabrous. Head with a few small punctures, none 
visible elsewhere. 
Head slightly convex, rounded, very slightly longer than wide; 
an impression commencing almost at base, continuous almost to 
middle, and then becoming circular, the circle enclosing a low 
elevation (invisible from some, and appearing tuberculate from 
other directions) ; antennae slender, subcylindrical, almost reaching 
apex of elytra, 1st joint slightly longer than 2nd-3rd combined, 
2nd not much shorter than 3rd, 3rd-5th gradually, 6th-10th per- 
ceptibly increasing in length, 11th once and a half as long as 
10th; fovese of undersurface deep, smooth- walled, almost connected. 
Prothorax mortar-shaped, much longer than wide, wider than head, 
truncate at base and apex; anterior two-thirds strongly convex; 
base with a deep and wide impression, no trace of one at apex.
