9th- 10th combined; corrugate at the sides; fovea3 of undersurface 

 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 1^ mm. 



Hab. — Sydney. 



A small species, which should be easily recognised by the 

 carinate head. 



Carphurus impunctatus, n.sp. 



9. 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 coxa?, 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 el3^tra, 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.
