. Diptera danica : genera and species of flies hitherto found in Denmark. Diptera -- Denmark. Orthorrhapha brachycera. neither Meigen's description nor his figure of the antenna (IV, Tab. 34, Fig. 2) is in agreement. The above described specimen is Zetterstedt's type-specimen; the author raentions the vestiges of two yellow bands at the base of abdomen; Mik mentions nothing about this (he describes the abdomen not at all), perhaps the species may be varying in this respect like pallipes. S. rufipes is very rare in Denmark, only one specimen, a male, has been taken by Stæger on Amager on *^/6 1

S. rufipes is very rare in Denmark, only one specimen, a male, has been taken by Stæger on Amager on *^/6 1844. It seems to occur on salt marshes, as iVIik also took his specimens in such a locality. Geographical distribution: ^— Denmark and down into Austria; if Macquart's rufipes is the same species it goes down into France. 5. S. pumilus Meig. 1824. Meig. Syst. Beschr. 53, 17, et 1830.
