The following list of Ambo^Tiese Diptera, characterized, together 

 with many Javanese species, by the late Dr. Doleschall (Nat. Tijd. 

 Nederlandsch Indie, 1856-58), will serve as a supplement to my 

 Catalogue. Should it appear that he and I have described the same 

 species as new, his names have the priority, and must be retained.
