508 NOTES ON THE GENUS STicMODfiRA, 



Three specimens under examination vary little in size and 

 colour, except in the more marked metallic reflections on 

 prothorax and elytra in one specimen. It belongs to the S. 

 producta Saund., S. insignis Blackb., and S. gentilis Kerr., 

 group, being nearest the last as to colour-scheme, but the 

 apex differs from that of .S'. jyroducta and S. f/entilis in beint; 

 mure, and from <S'. insiynis in being less acutely produced.

 some specimens sent for naming from the Brisbane Museum.
