AUSTRALIAN STRATIOMYIDjE (DIPTERA), WITH 

 DESCRIPTION OF NEW SPECIES. 



By Gerald F. Hill, F.E.S., Entomologist, Australian 

 Institute of Tropical Medicine, Townsville, N.Q. 



In his revision of the Australian Stratiomyidce, White* lists 

 30 species belonging to 18 genera. In the following paper the 

 writer proposes six new species, belonging to five genera, of which 

 two genera have not been recognised hitherto in Australia. The 

 apparently rare fly Negritomyia albitarsis Bigot, previously known 

 from Papua and Queensland, is recorded from the Northern Ter- 

 ritory. 



The specimens are all in a perfect state of preservation. Their 

 examination for the purpose of description was made in daylight, 

 with No. 4 ocular and 2 inch objective. Measurements are given 

 in millimeters. The figures were outlined with camera lucida.
