F. spinicoxa is somewhat eommon in Denmark; at Copenhagen, 

 Charlottenlund, Ordrup Mose, Ermelund, Dyrehaven, Lyngby Mose, at 

 Fure Sø and at Nyraad near Vordingborg; it has thus hitherto only 

 been taken on Sealand. My dates are ^k — ^/s, but I have records of 

 its occurrence to the first days ot September. It occurs in fens and 

 in woods on humid piaces and at water on bushes and in low 

 herbage. 



Geographical distribution : — Northern and middle Europe down 

 into Styria and Hungary; its northern limit is in Denmark, and it 

 occurs in England. 



Remarks: Zetterstedt quotes under Rhaphium nasutum Fall. 

 Mede.terus bilineatus Stæg. in litt. as sent to him from Stæger, but 

 this is certainly a mistake; we do not have P. waswto in Denmark; the 

 mentioned specimen was certainly the present species, which stood 

 in Stæger's collection determined as nasnta. As the specimen sent 

 to Zetterstedt was a female, the mistake is easily understood. Loew 

 mentions 1. c. also spinicoxa from Denmark, sent from Stæger.
