272 PROCEEDINGS OF THE AMERICAN ACADEMY. 



Upon comparing the Japanese variety with several examples of S. 

 viridis L. var. cinereoviridis Tull., which Dr. Schaffer gave me, I find 

 but few structural differences ; the European variety has more slender 

 mucrones and is clothed with longer bristles. 



S. viridis is extremely variable in coloration and the present variety is 

 the ninth to receive a name. The species ranges throughout Europe, 

 having been recorded from Sweden (TuUberg), Norway (Lie-Pettersen), 

 Finland (Renter), Russia (Scherbakow), Nova Zerabla (Tullberg), 

 France (Bourlet, Geoffroy), Switzerland (Nicolet), Germany (Renter, 

 Schaffer), Bohemia (Uzel), Tyrol (Dalla Torre), Hungary (Tomosvary), 

 Italy (Paroua), England (Lubbock,) and Ireland (Templetou). Outside 

 of Europe, it is known from Tunis (Parona), Siberia (Reuter), and South 

 America (Parona).
