I have seen this interesting insect in the parish of Nafferton, York- 

 shire, on the scanty remains of heath on the road to the hamlet of 

 Pockthorpe. The whole of the Yorkshire Wolds, now all enclosed, 

 were, sixty 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 following are also localities, among others, for this species : — 

 York, on the railway near Burnby, at Drewton near Market Weighton, 

 and at Scarborough; Bisterne, in Hampshire; the Isle of Bute and

 Arthur's Seat, near Edinburgh ; the Cheddar Cliffs, and Wells, Somer- 

 setshire; Walmer Forest and Languard Forest. I have also taken this
