TRIFIDyE. 349 



attraction in this species that it is in some degree shared by 

 the female. It will also come to sugar and more freely to 

 ivy-bloom, and has been found imbibing the moisture from 

 withered hawthorn leaves after a shower of rain. Formerly 

 plentiful in the outskirts of London, and most conspicuous, 

 from the wildness of its flight, round the lamps, now far less 

 common there, though a casual specimen will even yet come 

 through the open window into the room where I am writing, 

 and Mr. Fenn tells me that in some years it is still abundant 

 at Lewisham and Lee. Found throughout the Southern and 

 Western Counties of England, and in some years in abund- 

 ance ; less commonly in the Eastern Counties and the Mid- 

 lands, and more locally in the North, sometimes in plenty 

 in Cumberland; rarely on the coast of Durham. Probably 

 throughout South Wales, since it is common in Glamorgan- 

 shire, and occurs more rarely at Pembroke. In Scotland it 

 is found, though not commonly, in the southern portion, 

 the districts of the Tweed, Forth, Solway and Clyde, and 

 also in Perthshire ; in Ireland widely distributed, occurring 

 near Dublin, Galway, Sligo, and other coast localities. Abroad 

 its range appears to be unusually restricted, hardly extending 

 beyond France and Spain.
