C. antiqua is somewhat rare in Denmark or at all events rather 

 iocal; at Nyraad near Vordingborg (J. G. Nielsen), at Boserup and 

 Svenstrup near Roskilde (H, J. Hansen); on Lolland at Bremersvold, 

 in Kældskov, Dødemose and in Holmeskov at Saxkøbing (L. Jørgensen), 

 and in Jutland at Horsens (O. Jensen); the dates are ^h—'^k. 



Geographical distribution: — Northern and middle Europe down 

 into Switzerland and perhaps into France; it seems to have its northern 

 limit in Denmark, and it occurs in England.
