LARENTID.-E—LARENTIA. 185 



those nearest the summit are frequented. The natural flight 

 is at dusk and onwards, but from the diflicult nature of the 

 ground it frequents this is little observed. Perhaps its most 

 southern rcliaUc locality is the Black Mountain in Hereford- 

 shire ; but a single specimen was captured in 1872 on Durd- 

 ham Down, near Bristol, possibly in the act of migration 

 from some more mountainous district. Taken occasionally 

 on the high hills of Derbyshire near Dovedale; more abun- 

 dantly on the Pennine and other hills and moors of Yorkshire, 

 Lancashire. Durham, and Northumberland; and in multitudes 

 on Gonistoue. Blackcrag, and other Westmoreland and Tum- 

 berlaud mountains, in North Wales it is common at Glydyr 

 and in other siuiihir localities in Denbigh and Flintshire. In 

 Scotland on the hills of Berwickshire, Roxburghshire. Wig- 

 tovvushire. and other southei'n districts, but in the more 

 northern mountain districts, as in Perthshire, Aberdeenshire, 

 and Ross, to be found also on the moors at low elevations, and 

 often in plenty at the road sides, where these skirt the rocks. 

 Doubtless on all the hills of the mainland, and the Hebrides, 

 and common in (Orkney and Shetland. In Ireland Mr. J. J. 

 Walker has taken it so far !>outh as the shores of Bantrv Bay, 

 Cork , and it is found in (Jlare ; on Divas, and other hills near 

 Belfast; in Donegal and Derry ; probal)ly in othei' hill districts. 

 Abroad it is common in Iceland and Lapland and on the 

 mountains of all Northern and Central Europe, including 

 Germany; and in Eastern France and Belgium. Also 

 throughout the mountain ivgions of Central Asia ; and in 

 Nortli America in Northern and Southern La))rador; said 

 also to occur in the White Mountains and ilount \\'ashington ; 

 in Massachusetts, and in Colorado, though the specimens 

 from these last localities seem from their description rather 

 more like the next species.
