evening. The female is far more sluggish, yet in very hot 

 still weather may be seen in the same places, flnng in the 

 , afternoon, or swinging by its long legs from a culm of grass ; 

 but this is by no means a usual sight ; in ordinary weather it 

 hides among the grass. Locally abundant in the more chalky 

 portions of Surrey and Sussex, especially in Richmond and 

 Arundel Parks and the Box Hill and Mickleham districts, also 

 in other suitable places in Kent, Sussex, Hants with the Isle 

 of Wight, Dorset, Devon, and Somerset, and in the Scilly 

 Isles ; and in more restricted numbers — and localities — in 

 Essex, Suffolk, and even the borders of Cambridgeshire, but 

 apparently not in any other part of these Islands. Abroad 

 it is widely distributed and common throughout Central and 

 Southern Europe, to Turkey, and Corsica ; and is found in 

 Sweden and Norway.
