226 LEPIDOPTERA. 



as though dead. It flies about trees and bushes in the even- 

 ing, and also late at night, when it comes freely to light, and 

 even at times to " sugar " on trees, and to flowers, especially 

 those of Clematis vitalha, and thistle. It is the most generally 

 common species of the group, and formerly was plentiful in 

 the outskirts of London, coming commonly to the gas lamps. 

 There it is now less frequent, but occurs generally, and often 

 abundantly, throughout the southern half of England as far 

 as Derbyshire, Cheshire, and South Lancashire. In North 

 Lancashire it is scarce, and local in Yorkshire. In Scotland 

 it is recorded in Clydesdale, and at Bridge of Allan ; also in 

 Aberdeenshire, and as far north as Moray. In Ireland it has 

 been found in Galway and Kerry, and is said to be widely 

 distributed. Abroad it is common in Central and the greater 

 part of Southern Europe; in Livonia, Armenia and Asia Minor; 

 also evidently in some parts of Africa, since it has been 

 received — and named Vicaria — from the Congo.
