similar localitles and is often seen on flowers of Umbelliferæ, some- 

 times in rather great numbers. 



Geographical distribution:— Europe down into Italy; towards 

 the north to southern Sweden. 



Remarks: E. maculipes Zett. is a nearly related species, but cer- 

 tainly distinct; I have seen the female of the type, and it differs, as 

 mentioned by Zetterstedt, by having no scaly hairs on the femora, 

 and also in that the last abdominal segments are less, or almost not 

 at all narrowed.
