This insect appears towards the end of June, and is very abundant 

 in some localities ; a large colony existed on Hampstead Heath for 

 many years. Common at Bournemouth in July and August, on 

 Parley Heath and at Christchurch, Hants, at Sidmouth, Budleigh- 

 Salterton, &c. It has not to my knowledge been found in Scotland ; 

 but I have taken it in North Wales, at Barmouth.
