The beautiful female represented in the plate was taken with 

 other specimens in June at Birch Wood, in Kent, by Mr. Stand- 

 ish ; it has also been found on gravelly banks in July at Bexley, in 

 the same county, by Mr. Samouelle ; it has likewise occurred in 

 Epping Forest; Coombe Wood; Teignmouth, Devon; and Mr. F. 

 Walker has met with it at Southgate.

 took it at Bigbury Bay, Devon, 8th of September 1823. It has 

 also been observed near Bristol by Mr. Millard.
