This species is abundant in some localities on Plumstead 

 Common, at Charlton near Greenwich, and at Weybridge ; but 

 I found it most numerous in Sandown Bay, Isle of Wight, 

 where, in the middle of July 1851, both sexes were captured; 

 amongst these, a specimen of the male, 5 lines in length, oc- 

 curred, and also the very rare black variety. This species is 

 also plentiful beyond Southend, where many specimens were 

 captured running on the footpath at the top of the heights ; it 

 is also found on Deal sands, and on the slopes under the cliffs 

 towards St. Margaret's Bay.
