part to within a mile of Castle Eden Dene. It certainly is not 

 because of some peculiar food-plant, for I reared tlie larva on 

 almost any grass which was easily obtained.

This Butterfly frequents dry rocky places, or gravelly banks. 

 Wailes says it is ''almost confined to the Magnesian -limestone 

 district.*' It appears to occur on the coast wherever the locality 

 is suitable. "Berwick," Mr. Pattison; '' sea coast near Bam-

 Eales; Castle Eden, John Sang, 1859, W. Backhouse. I have 

 also found it plentifully at Black Hall Bocks, and have seen 

 the larva on grass on the sand-banks. Wailes states that it 

 swarmed ''some years ago" on old ballast hills near Jarrow. 

 I have also found it common on ballast hills close to Hartle- 

 pool, and in the railway cutting above Hart Station. Cassop is 

 given as a locality in Ornsby's Durham. This species has one 

 marked peculiarity, namely, the larva pupates below the surface ' 

 of the soil, and the pupa is smooth, bright shiny-brown, much 

 like that of a Noctua.
