from all other known species as to merit description. Superficially the species 

 resembles members of the hairy-eyed group of Tabanus. and most closely T. 

 neocirrus Ric. I know of no described species with similar broad forehead and 

 callus reaching eyes.

Hab. S.A., Adelaide (J. G. O. Tepper). 



Described from a single specimen somewhat abraded, but not closelv 

 resembling any species known to me. It presents a rather remarkable super- 

 ficial rememblance to Ectcnopsis victoricnsis Ferg., but the palpi and antennae 

 are very different.
