A series of specimens from South Australia appear to be 

 this species, judging from Macquart's description, though 

 there are a few discrei)ancies ; his type came from the East 

 Coast of New South Wales. 



The ivings have an appendix and two brown spots, which, 

 however, amount to little more than dark shading on the 

 transverse veins. Abdomen black, at base testaceous, with
