manner to some similar hiding-place. At dusk it flies volun- 

 tarily about the same situations, but does not seem so much 

 disposed as the last species to roam abroad. Generally distri- 

 buted, and usually common in suitable situations, throughout 

 England, Wales, and Ireland, except that records are want- 

 ing for one or two of the northern counties of England ; yet 

 found in Scotland in Wigtownshire, Ayrshire, the Glasgow 

 district of the Clyde Valley, Berwickshire, Midlothian, 

 Perthshire, Aberdeenshire, and Moray. Abroad it is 

 common throughout Central Europe, and found in the 

 south of Sweden and Norway, Livonia, Italy, Southern 

 and Eastern Russia, Bithynia, Syria, and Tartary.

 Along the hind margin is a goldeu-ljrown stripe, and a
