4 LEPIDOPTERA. 



readily to sugar and to flowers ; also occasionally attracted 

 by light. It appears to be most partial to cultivated land, 

 and is not uncommon in gardens, though more plentiful in 

 lanes, and at the edges of woods. Apparently found through- 

 out England and Wales, often commonly, though not every- 

 where so — perhaps least so on heath and forest land. In 

 Scotland it is found in the districts of the Solway, Clyde, 

 Forth, Tay, and Dee, and even in West Eoss, but does not 

 seeui to affect the hills or wilder districts ; and appears not 

 to have been observed in the Isles. In Ireland it is very 

 widely distributed and often common. Abroad its range is 

 wide — Central Europe, Southern Sweden. Northern Italy. 

 Western Siberia, India, and Japan.

All our species in this genus have the hind wings yellow 

 with a black submarginal band. The table below may be 

 useful.
