distinctly curved at its origin and curved upwards towards apex. 

 Halteres black.

C. daiici is common in Denmark; Ermelund, Holte, Geel, Skov, 

 Suserup Skov at Sorø, Bogø south of Sealand and in Jutland at Hejls 

 south of Kolding and at Jelling (Th. Mortensen, the author); my 

 dates are ^5 — ^Vio in 1917 to 1921; I have taken it in copula on ^7?. 

 The species may be taken with the net in low herbage, but it is often 

 seen outside of woods, f. inst. along roads on the umbels of various 

 umbellifers. 



Geographical distribution: — Europe, towards the north to 

 Lapland; also occurring in North America.
