242 NEW SPECIES OF AUSTRALIAN COLEOPTERA, II., 



Median channel deep and wide except on centre of disc, where 

 it is narrower. Two shallow longitudinal sulci near the base. On 

 foliaceous sides are two or more setiferous punctures near the 

 centre. Elytra (9x5 mm.) ovate, shoulders not angular, but 

 somewhat squarely rounded, widest at middle and narrowing to 

 apex. Striate, with six deeply cut striae on each elytron, exclud- 

 ing the two shallow stria* on epipluras. Intervals between strise 

 flat and glabrous; 3rd and 5th conjoined near apex, 5th rather 

 broader than others. Legs thin, femora unarmed, anterior tibiae 

 slightly thicker towards apex and a little curved on outer edge, 

 median and hind tibiae straight. What I take to be the £ differs 

 only in narrower form and thinner hind tibiae. Dimensions 

 15x5 mm. 



Hab. — Grose Valley, Blue Mountains (H. J. Carter and E. 

 W. Ferguson). 



The brilliant brassy sheen and the curiously shaped prothorax 

 mark this species as very distinct from any known to me. In 

 some respects like a small C. Howitti Pasc, it differs from that 

 species in its longer and more slender antennae, its more brilliant 

 colour, and in its distinct foliaceous prothorax, with its charac- 

 teristic setae on folia and epistoma. Apparently differs from C . 

 chalceus Bates, which is described from a single <J, in form of 

 prothorax, which is widest before middle and whose hind angles 

 are not produced or prominent. 



Cardiothorax austualis, n.sp. 



Very near preceding (C. aureus) in colour and general facies, 

 so that at first I was inclined to consider it as a var. of C. aureus. 

 Having lately acquired a large number of specimens, I can now 

 confidently describe this as a distinct species. Confusion will be 

 best avoided by the following contrasts : — 



C. australis. C. aureus. 



Colour dark bronze, shining, Golden bronze, shining, 



varying rarely to light bronze. 

 (Of 17 specimens before me two 

 only are as bright as the typical 

 C. aureus).
