“ In the parts of Meigen's collection to which I confined my attention (Muscidae Acalypt.) the species represented are few beyond all my previous suppositions. It is evident that he derived more from v. Winthem's and Wiedemann's collections than from his own ; or that the duplicates of which his heirs disposed to Mr.Winnertz included a material part of the whole. Yet even the little remaining I found to take much time to muster and survey ; the more so from their imperfect condition. ”
