trunks of oak-trees .and in some districts in equal plenty on 

 those of apple-trees. At about 4 p.m. it begins to fly over the

 trees throughout England, and in raany parts about orchards 

 and throughout the lowlands of Scotland, extending to Perth- 

 shire, Moray, and Dumbartonshire ; doubtless also in Wales, 

 though I find no record. In Ireland it is found near Cork ; 

 and abroad is distributed throughout Central Europe, 

 Southern France, . Castile, Sweden, Livonia, and Western 

 Russia.
