LARENTID.E—MESOTYPE. 5 



:away, to settle in another part of the same patch of bedstraw. 

 Here it sits with wings erect, and closely pressed to each 

 ■other over the back ; and will even lie down upon its side on 

 the sand to escape observation. Late in the afternoon and 

 about sunset it iliea about of its own accord, but never seems 

 to leave the neighbourhood of its food plant. It is one of 

 the coast-frequenting species which are still to be found on 

 the Breck-sands of Norfolk and Suffolk, and may possibly 

 .have inhabited this locality from the time when it formed a 

 portion of the coast of a post-glacial sea. Yet this seems 

 ■scarcely so evident as in the cases of some of the coast 

 NoducB previously mentioned, since this species is not wholly 

 ■a seaside insect, but is known to frequent some of the spots 

 upon the South Downs in which the (ialimn is abundant, has 

 formerly been taken in a similar manner on Cambridgeshire 

 ■chalk hills, and quite recently by Mr. W. E. Butler on a 

 chalk hill at Streatly, on the borders of Berkshire. But 

 these cases are quite exceptional, and the coast sandhills are 

 its chosen home ; on them it is found in plenty at Folke- 

 stone, Deal, and elsewhere in Kent ; in Sussex ; at Fresh- 

 water, Isle of Wight; at Exmouth and Dawlish Warrens, 

 Devon ; on Burnham Sandhills, Somerset ; on the sandhills 

 between Yarmouth and Caistor, Norfolk ; the coasts of 

 Cheshire, Lancashire, and Cumberland; and apparently in 

 very far smaller numbers in Dorset and Wilts. In Wales it 

 is found freely upon the Glamorganshire coast, but is, I 

 think, quite absent from the extensive sandhills of the 

 further West. In the Northern portion it is common on 

 those of Flintshire. In Scotland, according to Dr. F. B. 

 White, it has once been taken in the " Tay " district— pro- 

 bably Perthshire — but this seems to require confirmation. In 

 Ireland it has been found on the extensive sands near New- 

 castle, CO. Down ; and nearly forty years ago I well remember 

 that the late Mr. Edwin Eirchall found specimens, to his 

 great surprise, upon ;Mangerton Mountain, Kerry, at an 

 -elevation of 800 feet above sea level.
