Exoneura hackeri t'kll. Brisbane. Feb. 8, 191(3, ? (220), ^ (216). 



The female represents a varietj' without the dark abdominal bands. The 

 male has the bands ; its face markings resemble those of E. clarissima Ckll., but that 

 sjx-cies has the scape white in front, while in hackeri it is entirely black. E. hackeri 

 was described as a variety of E. anyo phorae , but I think it is a distinct species.
