No examples of this insect have been found in the north 

 of England, nor is it frequently met with in the vicinity of 

 London ; it was taken twice or thrice, some years ago, at Old 

 Brompton. It occurs in profusion at Purfleet, and in several 

 places in Kent, and abounds in the vicinity of Bristol. Mr. Wal- 

 cott has captured several gigantic examples of the male, some 

 of which are eight lines in length. The males are frequently 

 entirely hoary.
