Western Palearctic region only, the Eastern species being 
nearly all aberrant. 
In America we have in all 8 species, of which 6 are 
found in the Rocky Mountains. Of these 2. tyndarus 
is inseparable from the European species even as a 
variety. . epipsodea has a remarkable resemblance to the 
northern form of medusa; E. disa var. mancinus is hardly 
distinguishable from the Lapland insect. £. vidleri is so 
like sedakovi that I separate it with some doubt. £. dis- 
cowdalis is common to Arctic America and Asia, L. sofia is 
but a variety of the Siberian maurisius, and EF. magdalena, 
which we only know from a very restricted area in the 
highest mountains of Colorado, is peculiar. In Arctic 
America we know four species at present of which Z. rossi 
and #. discoidalis also occur in Asia and £. fasciata is 
peculiar. 
There is not a single species in Eastern America and 
though one or two °Erebia-like insects have been dis- 
covered in Patagonia, there is in this genus nothing 
analogous with what we find in Colias and Argynnis, 
where outlying, more or less aberrant species are found in 
spots suitable to their habits in the Andes and Antarctic 
America.
