PH YCITID.t:— HOM.-EOSOMA. 4; 



as has been pointed out by ilr. Robert Adkin — much pro- 

 tected from the eye by its singular resemblance when at rest 

 to the seeds of certain tall grasses which hang over and lie 

 upon the thistles at the same time. At dusk it is readily 

 seen in flight from its white colour, and is often to be found 

 sitting upon thistle blossoms and other composite flowers. 

 Partial to chalky and sandy districts, but not wholly re- 

 stricted to them ; also rather attached to the sea coast ; 

 found throughout the southern and eastern counties of 

 England, and in Oxfordshire, Gloucestershire, and even 

 Westmoreland. It was rather scarce in Pembrokeshire, but 

 found also at Llangollen, in North Wales ; in Scotland it 

 has been taken in Fife by Mr. W. Evans ; and in Ireland at 

 Timoleague, Cork, by the Messrs. Donovan. Abroad it is 

 widely distributed through Central and Southern Europe, 

 Livonia, Finland, and also Armenia, and other parts of 

 Asia.
