abundance of dwarf-sallow grew in the vicinity, and also, as 

 far as I can remember, thistles, bedstraw, wild thyme, and a 

 short kind of grass, from which latter I expect that I dis- 

 turbed it ; at any rate the insect was Hying low over the barren 

 sand when I caught it. The clay was showery, with occa- 

 sional gleams of sunshine. During one of these gleams I 

 took the insect." Possibly some small migration of this 

 species may have taken place about 1858. At any rate, I 

 know of no subsequent capture in Wales, and of very few 

 indeed elsewhere ! These seem to have been in 1880, when 

 one was secured on September 8th on the cliffs at Dover by 

 Dr. Battershell Gill, and another near Swanage, Dorset, by the 

 Eev. C. R. Digby. I am not aware of any subsequent captures, 

 and its range, if it may so be called, seems to be limited 

 in this country to Kent, Dorset, Devon ; Glamorganshire 

 in South Wales ; and the single capture in Ayrshire, South 

 Scotland. Abroad it is found in France, Southern Germany, 

 Spain, and most other parts of Southern Europe, includ- 

 ing Turkey; Madeira, Egypt, Morocco, Algeria, and other 

 parts of Northern Africa ; and the Cape Colony, South Africa.
