has larger eye-spots. It is the Pyrenean form, but some of our 

 Perthshire specimens resemble Herrich - Schaffer's figures very 

 much. 



In Scotland, Epiphron does not seem to descend lower than 

 1500 feet above sea-level, at which elevation I have found the 

 larva. 



Zygce7ia exulans inhabits grassy places on the mountains of 

 Aberdeenshire, at an elevation of 2200 feet and upwards. On 

 the Continent two forms occur — exulans proper, which is found 

 on the higher Alps and Pyrenees, and is more or less suffused 

 with ochreous ; and the var. vanadis Dalm., which has scarcely 

 any ochreous tinge, and is restricted to the Scandinavian moun- 

 tains and to Lapland. Our form seems to be intermediate be- 

 tween these two, and I have proposed for it the name of var. 

 sichochracea. 



Pach7iobia hyperhorea occurs on some of the higher mountains 

 of Perthshire and Aberdeenshire — usually on the ridges of the 

 hills. On the Continent it ranges from Lapland to the Swiss 

 Alps, and eastwards to Carinthia (var. caniica) and Hungary. It 

 is a very variable and beautiful insect, and does not in Britain 

 probably descend below 2500 feet or thereby. 



Anai'ta melaiiopa inhabits the higher parts of some of the 

 mountains of Perthshire, Aberdeenshire, Sutherland, and Zet- 

 land, and has been reported from the west of Scotland. It gen- 

 erally does not descend below 2000 feet, but in Zetland has been 

 taken at about 400 feet. Out of Britain it is almost confined to 

 Lapland, though also occurring in Labrador, and a variety (which 

 I have also seen alive), on the Swiss Alps. 



A. cordigera is scarcely a true mountain species (as defined 

 above) ; for though it occurs on the hills up to 2200 feet or up- 

 wards, yet it is frequent at as low an elevation as 1000 feet, or 

 even lower, in Perthshire, Aberdeenshire, and Morayshire. On 

 the Continent it occurs in central and north Europe, going as far 

 south as the Alps, and as far east as the Ural. It also inhabits 

 Labrador. 



Psodos coracina (the trepidaria of British lists) is — so far as my 

 experience goes — confined to the ridges of the higher mountains 

 of the north-east and the north-west of Scotland, not descending 

 below 2000 feet. In Europe it ranges from the , mountains of 

 Lapland to the Pyrenees, going east to the mountains of Galicia, 

 and perhaps reaching east Siberia and the Amur. In Scotland 

 I have almost invariably found it associated with Azalea (or
