agS LEPIDOPTERA. 



commonly in Switzerland, reported that it settled constantly 

 upon Dryas odopctala when flying about in the daytime. Dr. 

 Buchanan- White found it equally fond of settling upon 

 Empctrum nigrum in Scotland ; others find it flying over and 

 sitting upon heather ! Its most extreme southern locality 

 with VIS appears to be on the Black Mountain, Herefordshire, 

 but it is found on moors and hills in Yorkshire, Lanca- 

 shire, Durham, Cumberland, and Northumberland, It seems 

 impossible that it can be entirely absent from Wales, though 

 I find no record there. In Scotland it is widely distributed 

 in Roxburghshire, Fife, and elsewhere in the Edinburgh 

 district, the mountains of Perthshire, Inverness-shire, Aber- 

 deenshire, Renfrew, Dumbartonshire, Argyle, the Orkneys, 

 and in abundance on high moors in the Shetland Isles — 

 indeed, Mr. J. A. F. X. King found it in Unst " in such 

 multitudes that the very surface of the herbage seems 

 moving." In Ireland it occurs on the Dublin mountains, 

 and on the Mourne Mountains, Co. Down. Abroad its 

 range is northern, through Scandinavia, Finland, and Lap- 

 land, as well as in the Alpine regions of Central Europe.
