I HAVE seen this Interesting insect in the parish of NafFerton, 

 Yorkshire, on the scanty remains of heath on the road to the 

 hamlet of Pockthorpe. The whole of the Yorkshire Wolds, 

 now all enclosed, were, fifty years ago, open downs, with 

 heath and gorse scattered here and there: it is but very little 

 that is left. Then you could ride over the Wolds, so I am 

 told, from Driffield to Malton, twenty miles, without meeting 

 with a hedge or a gate — all was turf — fine old downs: now, 

 'quantum mutatus,' it is one of the principal corn-growing 

 districts of England. The naturalist must sigh for 'il tempo 

 passa,' Avith which has flown the Great Bustard, and doubtless 

 many other species of birds once common, or which were at 

 all events far more numerous than they are now; but he must 

 console himself with the absolutely true adage that "whatever 

 is, is best." 



The following are also localities, among others, for this 

 species: — the Isle of Bute and the Isle of Arran; near Durham, 

 South Shields, Castle Eden Dene, in the county of Durham; 

 the Gog Magog Hills, the neighbourhood of Newmarket and 

 Gamlingay, Cambridgeshire; Salisbury Plain, in A^'iltshire;
