 reddish ring at the extremity of the antennae.

 then be met with in gardens, visiting such walls as are 

 covered with trees trained upon trellis work, in a 

 warm sunny aspect. When once she has begun to 

 make her appearance, she frequently returns, and 

 during a long period ; and she may always be known
