striato punctulatis, humeris vix callosis ; mesosterno quam C. 

 luctuosce (Pasc.) vix latiori ; coxis anticis haud contiguis. 



[Long. 1 (vix), lat. % line (vix). 



In the example before me (winch may be a little abraded) the 

 lighter coloured scales are scarcely indicated on the upper surface 

 except on the sides of the prothorax, while they densely cover 

 the undersurface. The mucro at the inner apex of the front tibise 

 is feebler than in the other Cydmoia known to me, and the front 

 margin of the prosternum is a little more decidedly emarginate. 

 Though little different in form from its congeners, this species is a 

 trifle narrower. 



S. Australia, near Petersburg. 



The following is a tabulation of the described species of 

 Cydmcea : — 



A. Front coxae contiguous. 



B. Colour of scales not metallic golden-green. 

 C. Tibi?e and tarsi (as well as antennae) 



reddish or testaceous himaculata, Pasc. 



CC. Colour black, with white scales, an- 

 tennae ferruginous, legs obscure pusilla, Pasc. 



CCC. Antennae black (or with only the 

 scape ferruginous). 

 D. Mesosternum wide ; upper surface 

 with well defined snowy-white 



patches luctuosa, Pasc. 



DD. Mesosternum less wide ; ujiper 

 surface devoid of sharply limited 



markings ohscura, Blackb 



BE. Colour of scales golden-green viridula, Fasc. 



AA. Front coxse distinctly separated. 



B. Antennae black, mesosternum very wide, 



prosternum scarcely emarginate in front diversa, Blackb. 

 BB. Antennae ferruginous, mesosternum less 

 wide, prosternum more distinctly 



emarginate in front invalida, ^lackh.
