428 DESCRIPTIONS OF TWO NEW SPECIES OF CARENUM, 



posterior angles, rounded at the posterior angles, obliquely 

 narrowed behind them, and lightly sinuate before the base ; base 

 widely sublobate, truncate ; marginal border narrow, not more 

 prominent at posterior angles, thicker and more reflexed on the 

 base ; median line finely and distinctly marked ; three marginal 

 punctures on each side. Elytra oval (11 x 6J mm.), lsevigate, 

 subconvex j the disc depressed towards the base, slightly emar- 

 ginate between the shoulders ; sides lightly and evenly rounded ; 

 marginal border narrow ; a row of equally placed punctures along 

 the margin, and four punctures in a cluster on the base of each 

 elytron near the humeral angle ; two discoidal punctures on each 

 elytron, one near the humeral angle, the other towards the apex. 

 Prosternum smooth and strongly excavate between the coxae. 

 Anterior tibice bidentate ; legs as in C. scaritioides and allied 

 species. 



Length 21, breadth 6f mm. 



Hob. — "VV.A. (between York and Yilgarn). 



This species belongs to the same group as C. scaritioides, 

 Westw. ; but it is a much flatter insect and differs in the shape of 

 the prothorax, which is less shortly rounded behind the posterior 

 angles and has the base truncate, sublobate, and more strongly 

 margined than the sides. It seems nearly allied to C. irtcon- 

 spicuum, Blackb., which, however, from the description, has the 

 prothorax with the anterior angles advanced, and the hinder part 

 differently shaped from C. ignotus. 



Carenum habilis, n.sp. 



Form short, broad. Shining, head black (a greenish tinge on 

 sides of throat); prothorax deep purple-black with broad metallic 

 green margin, undersurface greenish towards the sides ; elytra 

 purple-black (the purple tinge more conspicuous towards the 

 sides) margined with green, inflexed margins green; abdomen and 

 legs black. Head subquadrate, transverse (3 J x 5 J mm.), smooth ; 

 frontal sulci curved, not connected behind, deep and almost 

 parallel backwards, extending lightly forwards towards base of
