some to feed. If the weather becomes at all cloudy it is 

 said to conceal itself at the roots of the grass and herbage. 

 It shows a curious partiality for the rugged edges of wild 

 precipices on the mountain limestone, flitting about over the 

 chasms and settling on the vegetation along the extreme 

 verge. Here it is tantalisingly easy to see, but in its 

 ordinary haunts it is by no means distinctly visible when on 

 the wing, and will sometimes appear suddenly settled within 

 a yard or two of the collector — or vanish like a thought. 

 The Rev. Canon Cruttwell tells me that in intensely hot 

 sunshine it will congregate in bushes of juniper, yew, and 

 guelder-rose, from which it may be beaten out in numbers. 

 A local species, but sometimes common in such situations as 

 are here mentioned, especially on the coast, in Kent, Sussex ; 

 Guildford, Mickleham, and Box Hill, Surrey ; the Isle of 

 Wight ; the Isles of Purbeck and Portland, and Lyme Regis, 

 Dorset; Dartmoor and also Seaton, Devon; Cornwall, 

 Somerset, Gloucestershii-e ; the chalk districts of Oxfordshire 

 and Cambridgeshire ; and suitable spots in Cheshire, Lanca- 

 shire, Yorkshire, Westmoreland and Cumberland. In Wales 

 it is common on the coasts of Glamorganshire and Pembroke- 

 shire, at Barmouth and Llandudno in North Wales, also 

 in Denbigh, Carnarvon, and Flint, and at Holyhead in 

 Anglesea. In Scotland it used to be found upon Arthur's 

 Seat, Edinburgh, and is still known to occur in Berwickshire, 

 Aberdeenshire, Moray, Perthshire and Dumbartonshire. In 

 Ireland local and scarce, occurring in the Counties of Galway, 

 Sligo and Down. Abroad it is found throughout Europe 

 except the coldest portions ; and in Asia Minor and Armenia.
