called ‘‘ Grass”? Erebias (a definition we owe, I think, to 
Mrs. Nicholl) when they occur at a high level. 
The specimens exhibited are such that they will no doubt 
be recognised by Fellows who have done any collecting in 
Switzerland at over 5,000 ft. as very usual, and I believe there 
are sundry varietal names to which they are entitled. It is 
not the actual forms, but their association that claims attention. 
When the resemblance between melampus and pharte at 
Le Lautaret attracted Mr. Tutt’s attention in 1896, he thought 
that it signified that the two species were there connected by 
intermediate links that showed they were one species. On 
examining these species for my communication to the Society 
in 1898, I found nothing in Mr. Tutt’s collection to substantiate 
this view, but merely that specimens of each species closely 
approached the other in appearance. I have not unfortunately 
any of Mr. Tutt’s most illustrative specimens, and I did not pay 
enough attention to these species last summer to meet with 
such intermediate forms, but those I exhibit show a consider- 
able approach between the two forms, and I must refer to 
Mr. Tutt’s observations in proof that these do not show so 
much in this direction as they might. 
It will be noticed, however, that the general appearance 
of the two species is very close, and that the two rows (one 
of each) that I exhibit have a very close general aspect, that 
differs considerably from the equally close general aspect of 
the two rows (of pharte and manto) from Guarda. I have 
placed between the two rows of pharte, a row of the species 
from Carinthia, much brighter and more richly marked than 
the species usually presents in Switzerland, but the ordinary 
pharte of Switzerland does differ from the special forms 
exhibited, somewhat in this direction. It is perhaps apposite 
to add that this form of pharte was accompanied by an 
equally bright form of eriphyle on the Koralp. This summer 
at Le Lautaret I also found specimens of ceto of a size and 
colouring that made them indistinguishable from pharte and 
melampus until caught; I exhibit five of these specimens in 
contrast with ceto from a lower level. 
I may add that I think epiphron ought to be added to 
this group (as also to the Guarda set) as another member,
