DIPTERA. — Species quoted as allied or of doubtful identity in Osten Sacken's 



Paper on Limnobina. 

 Limnobia (dicranomyia) morio Fabr. (Eur. and N. Y.) — Limnobia tristigma 

 0. S. (111.) and L. tripunctata Meig. (Eur.) — AmalojDis inconstans 0. S. (U. S.) 

 and Limnobia littoralis (Eur.) — Several N. A. sp. of Trichocera are also refer- 

 red to (p. 242) as apparently identical with European species. — In all 3 species. 



It will be seen from the above that no less than 36 authors — viz., 

 placing them in alphabetical order, Beauvois, Boisduval, Clemens, 

 Curtis, Dejean, Rob. Desvoidy, Doubleday, D'Urban, Pidwards, Erich- 

 son, Otto Fabricius, Fitch, Grodart, Grote, Gruenee, Hagen, Harris, 

 Htibner, Kirby, Klug, LeConte, Loew, Macquart, Mannerheim, Mel- 

 sheimer, Menetries, Morris, Mulsant, Norton, Osten Sacken, Saussure, 

 Schaum, Staeger, Staintou, Uhler and Walker — have testified to the 

 existence in the Old and New Worlds of identical forms which cannot 

 be supposed to have been introduced. Whether we decide by the 

 number of the names, or by the great scientific weight of very many of 

 them, the balance of authority is certainly against Prof. Agassiz. 



* Can this be Heteroneura albimana (no author) of Loew's first list.? 

 f Probably the sp. inclescr. in Loew's third list.
