Revision of the Genus Erebia, 193 
Hrebia nerine. 
This is a species confined to the eastern alps, occurring 
in the Lower Engadine and valleys south of the Stelvio 
pass, in great abundance at Riva as low as 1,500 feet, 
where I took it fresh on very hot rocky slopes as late as 
the end of July, at Campiglio, up to 5,000 feet, and on 
the Mendel Pass, in the Italian Tyrol, where Mr. Tutt 
found it still fresh on August 11th. <A variety, which 
is called reiehlini, H.-S., occurs in the Salzkammergut 
and differs from the typical Tyrolese form in having the 
chocolate bands of the forewing above faint and ill-defined 
and the ocelli smaller. On the underside the ocelli of the 
hindwing are faint or absent. 
Another variety, morula, Speyer (cf. Stgr., Iris, vin, 
p- 286), which Staudinger calls a small alpine variety, is 
distinguished in typical ¢ specimens by the almost uniform 
dark-brown colour of the hindwing below, without the 
whitish dusting which in many of the typical forms 
almost forms an irregular band. I do not know where, if 
anywhere, this form occurs as a variety. “ Schluterbach” 
and “Preth” are two localities, and the Leisser Alp in 
South Tyrol is cited by Ruhl. Mr. Tutt, at a meeting of 
the Entomological Society, disputed the possibility of 
separating these named forms, and exhibited a long series 
showing considerable variation from the Dolomite Alps. 
But the few specimens I possess of retchlint and morula 
do show the differences mentioned by Staudinger, 
and none of those I saw of Mr. Tutt’s or of my own 
taking, agreed with them; so that I am inclined to let 
these varietal names stand. 
With regard, however, to the var. stelviana, Curo, with 
which specimens in Frey’s collection, named var. 2talica, 
are identical, and of which I have specimens from the 
Stelvio pass, Bormio and the Val Muranza, I can see no 
difference from the typical form worth noting. 
Nerine may easily be confused with some forms of 
E. pronoe, from which however the underside always fur- 
nishes a distinctive character. It may also in some forms 
be confused with large brightly marked specimens of 
E. stygne, which has the inner side of the band on the fore- 
wing below always sharply defined (also the case in 
E. evias); whilst in nerine the chocolate colour is diffused, 
spreading to the base of the forewing below.
