1 1 ah. S. W. Australia, Yallingup (Turner), October 

 L913. 



Closely related to flaviceps, Cam., but differs in the straight 

 first abscissa of the cubitus, in the colour of the basal 

 tergites, in the striation of the grooves by the median area 

 of the second tergite and in the very much smaller raised 

 areas at the anterior angles of the same tergite. The 

 terebra is also considerably longer. 



As I have not seen several of the Australian species of 

 this genus described by Szepligeti, I am unable to give a 

 key to the species. 



Subfamily AGATHINAE. 

 Genus Micro dus.

I have not seen M.pedunculMus, ^zop. (1905), described 

 from Sydney. In this species the mediefian vein is obsolete, 

 which is not the case in any species described here.
