Rev. F. W. Konow (Zeit. Hym. Dipt., p. 36, igoB) published a 

 similar synonymy for Empria. 



Up to the present time a number of si)ecies of this group have been 

 lumped under the name viaculata Norton, but on studying these forms 

 carefully and examining the saws there seems to be a number of allied but 

 distinct species. At the present lime a revision of this genus seems un- 

 advisable, but at some future date such a paper may be published. It 

 would greatly simplify matters if the various economic entomologists would 

 refer their material to a specialist.
