232 THE DIPTERA-BRACHYCERA OF TASMANIA, 



only one species has been described ; this species, E. 

 hrevirostriii, was described by Macquart from a single 

 female; it is not typical of the genus, and in the absence 

 of a specimen of the male^ it io impossible to be certain 

 as to its exact position. Excluding this species, four 

 typical species are now known to occur in Tasmania; all 

 these have the proboscis lengthened, the length varying 

 from two to three timesi the height of head.
