XL. — Exotic Muscari(ke (Diptera). — IV.''^ 

 By J. R. Malloch, Urbana, 111., U.S.A. 



I HAVE not adhered to my previous method in segregating 

 tlie species from different continents under distinctive 

 headings in this paper, as I have had to list a number of 

 species under one generic name which have previously been 

 placed in another genus, and for clarity have run the notes 

 all under the generic name, thus preventing me from listing 

 the species as heretofore.
