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 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.

 it is brownish pruinose, a little shining; acrostichal bristles somewhat
