414 Mr. J. E. Malloch on Exotic Muscarida3. 



XL. — Exotic Muscaridee (Diptera). — IV.* 

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



I HAVE not adhered to my previous method iu segregating 

 the 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.

 black. Thorax quadrivittate. Abdomen faintly checkered.
