C. gramineus is common in Denmark; Amager, Vester Fælled, 

 Utterslev Mose, Ordrup Mose, Ermelmid, Dyrehaven, Lyngby Mose, 

 Hillerød, Svenstrup between Roskilde and Ringsted, Faxe Ladeplads; 

 on Funen at Odense, Veflinge and Hoffmansgave ; in Jutland in Greis- 

 dalen and Højenbæk Dal at Vejle, Horsens, Laven near Silkeborg, 

 Frijsenborg, Gjerlev near Randers Fjord and Frederikshavn, and on 

 Bornholm at Almindingen, Hammeren and Hasle. My dates are '^Va—^l^. 

 It occurs on bushes and in grass and low herbage in fens and woods. 

 Verrall thinks that it possibly occurs in more dry localities than the 

 other species, but this is not confirmed by my experience; only it 

 is perhaps more commonly found outside w^oods. 



Geographical distribution : — Europe dov^n into Spain ; towards 

 the north to northern Scandinavia, and in Finland.
