F. elegantida is somewhat rare in Denmark, but has been taken 

 in several localities; at Copenhagen in Frederiksberg Have, Damhussø

 author). Nøddebo (the author) ; in Jutland at Madum Sø near Skørping 

 (Kryger) and at Hulsig north of Frederikshavn (Th. Mortensen). My 

 dates are ^^/t — ^"^/s. It has been taken at the horders of lakes and 

 ponds. Tlie pupa was found in the sand at the border of Donse 

 Dam by Mr. Schick on ^'^h. 



Geographical distribution: — Northern and middle Europe down 

 into France; towards the north to northern Sweden, in Finland and 

 in Siberia. 



Remarks : Loev^ raises 1. c. ahnost a doubt with regard to Zetter- 

 stedt's determination ; it seems as if Loew has understood Zetterstedt's 

 expression about the legs: "posticorum femoribus apice . . . tibiisque 

 apice tarsisque omnibus . . . atris" as if all tibiæ were black at 

 the apex, while Zetterstedt evidently means only the hind tibiæ; on 

 the other hånd Zetterstedt's expression: "seta longitudine antennæ" 

 is erroneous-
