 rings, that give the common name (Ringlet) to the species, or has 

 them represented only by a small white dot. I have no recent 

 records of this species except " Jesmond," Mr. Henderson, and

This is exclusively a moorland species, occurring freely on 

 most of the mountains, moors, and mosses. Wailes gives the 

 following list of localities, apparently from his own knowledge : 

 *' Needless Hall Moor — moors about Cambo — Prestwick Car — 

 Muckle Moss, near Haydon Bridge — moss near Crag Lough." 

 Mr. Backhouse gives ''moors near Shull." Ornsby's Durham 

 gives "high marshy ground, near Hoppyland. Rev. E. Blenk-

 Bog, in the Rede water district, in 1868-70. Mr. L. S. Brady 

 found it "fairly common about the ^Northumberland Lakes in 

 1890." I had the pleasure of making its acquaintance on Green- 

 leighton Moor in 1891, under the guidance of Mr. Pinlay of 

 Meldon. It was tolerably abundant, and I secured a nice series 

 in little over an hour, after which, rain came on and we got no 

 more. In the face of these quite recent ^Northumberland records 

 I am surprised to see it stated in Mr. Barrett's new work that 

 it " seems to have been exterminated in IS'orthumberland."
