S. aeneicoxa is not rare in Denmark, but however much less 

 common than the foliowing; Lersøen, Charlottenlund, Ordrup Mose, 

 Dyrehaven, Fure Sø, Hillerød, Svenstrup and Faxe Ladeplads; on 

 Funen at Odense and Veflinge; in Jutland at Hald near Viborg, and 

 fmally on Bornholm at Rønne, Allinge and Almindingen. My dates 

 are ^^h — ^^/s. It occurs at the horders of water in low herbage and 

 on water piants, thus not rarely among reeds. 



Geographical distribution:— Northern and middle Europe down 

 into France; towards the north to southern Sweden.
