place. In the evening it is a familiar object, Hying gently 

 in almost every garden. Very common in those of the 

 suburbs of London, and also to be found in plenty throughout 

 the Southern, Eastern, Western and Midland Counties of 

 England ; less common or even rare in the North, and I do 

 not find any record of its occurrence in Scotland — though it 

 can scarcely be altogether absent. In Wales I know it to be 

 plentiful in the Southern Counties but except at Colwyn 

 Bay have no information as to North Wales. In Ireland it 

 is widely distributed but is said not to be common. Abroad 

 it is widely distributed throughout Central Europe, becoming 

 larger and paler in colour in Swiss Mountain districts ; and 

 is found in Sicily, Livonia, Finland, Dalmatia, Greece, 

 Bithynia, Armenia, Siberia, Tartary, and Northern Africa.
