 Dyrehaven, Geel Skov (the author), Holte, Suserup 

 Skov at Sorø (Th. Mortensen), Bogø south of Sealand, on Langeland 

 at Lohals (the author), on Falster at Marienlyst (Th. Mortensen) 

 and in Jutland at Hejls south of Kolding and Ry (the author); the 

 dates are Vs — ^Vio in 1917 to 1921. It occurs in the same way as
