when approached. In cooler weather it may occasionally be 

 boxed upon the thistle. At dusk it flies of its own accord in 

 the same wide zigzags, or visits the blossoms of ragwort and 

 thistle ; later at night being readily attracted by light. An 

 abundant species in Norfolk and Suffolk ; also found, usually 

 more sparingly, in Kent, Sussex, Dorset, Devon, Cornwall, 

 Wilts, Gloucestershire, Herefordshire, Oxfordshire, Herts, 

 Cambridgeshire and ^'orkshire ; also in Wales, where Dr. 

 Freer has taken it in Anglesea ; but apparently not in other 

 portions of the United Kingdom. Abi'oad it is common 

 throughout Central and Southern Europe, and found in 

 Finland, Russia, Pontus, and Persia.
