72 REVISION OF THE AUSTRALIAN AJLVHYGMIDES, 



placed quite closely in the rows, nearly as fine and closely placed 

 as those of C. cupripennis, Blackb.]. This species also resembles 

 C. vigilansj Blackb., but is very much smaller, with the eyes a 

 little less approximate and the punctures of the elytral series deep 

 and sharply defined, whereas in viyilans they are so faintly 

 impressed that even on the discal part of the elytra they might 

 almost be called subobsolete.

Sat late ovalis ; sat convexus ; minus nitidus ; cyaneo-niger, 

 prothorace sat laete cyaneo, elytris eeneis obscure purpureo- 

 tinctis ; oculis quam antennarum articuli basalis longitudine 

 multo minus inter se remotis ; sulcis ocularibus baud plane 

 nullis ; antennis robustis quam corporis dimidium sat bre- 

 vioribus, apicem versus parum incrassatis, articulo 2° quam 

 ps 2"Sq^e conjuncti vix longiori quam 4^^ 5"^que conjunct! 

 sat breviori, articulis apicalibus quam praecedentes haud 

 brevioribus ; prothorace quam longiori (et postice quam

 a basi antrorsum sat sequaliter sat arcuatim angustato, dis- 

 tincte subtiliter minus crebre punctulato, basi media sub-

 This species is somewhat isolated, but its place in the tabulation 

 is, I think, among its real allies. If its colouring is constant (I 

 have seen only two specimens) it is easily known by the cyaneous 

 tone of its undersurface, together with its bright blue prothorax 

 and dull bronzy-seneous elytra, which are more or less tinged with 

 dark purple. Its eyes are not bordered by true sulci, but the
