APOLLO BUTTERFLY. 
This insect was first introduced into our British 
lists, in consequence of it having been supposed, 
through somo mistake, that a few continental speci- 
mens in the possession of Lord Seafortb, were pro- 
cured from the Island of Lewis, one of the Hebrides. 
Since that time, it has been oftener than once figured 
and described as a British species ; but no authentic 
instance is on record of its having been observed by 
any one — a circumstance which may fairly be as- 
sumed, in the case of such a marked and conspicu- 
ous objeot, as a sufficient indication that it is not an 
inhabitant of this island. We have been assured, 
however, that it was noticed on the wing last sum- 
mer in some part of the west coast ; and, though in- 
clined to think that this must be a mistake, we will- 
ingly avail ourselves of the excuse which it affords 
for retaining, in the mean while, such an ornamental 
insect among our indigenous species. On the Con- 
tinent, it inhabits the Alps, Cevennes, the mountains 
of Auvergne, and various parts of Norway and Swe- 
den, in considerable numbers. Its flight is said to 
be slow and heavy.
