Rannoch, &c., but is rather local. It is widely distri¬ 
buted in Scotland, and is also found in the north of 
England. Scottish specimens appear to be slightly 
larger than English. This species does not range so 
far up the mountains as C. Davus, for from some ob¬ 
servations made last summer in Inverness-shire, 
found that E. Medea was scarcely seen above 800 
feet, while G. Davus attained an elevation of up¬ 
wards of 2000 feet, both'species being found together 
from 200 feet up to 800 feet above the sea level. 
Both species are found, I believe, at the sea level.—•

16. Pieris Brassicm L. is as abundant in Perthshire 
as it is elsewhere throughout Britain. It is of course 
however more abundant in cultivated districts than 
on the moors, and is probably never found on the 
higher mountains. Scottish and English specimens 
are identical in appearance. In Galloway, during 
the last war with France, it was termed, from its 
colour, the “French Butterfly,” and hunted down 
and destroyed wherever found by the children, who, 
on the other hand, showed their patriotism by pro¬ 
tecting the “British Butterfly” {Vanessa urticoe ).—

To these two species what has been said regarding 
P. Brassicce also applies. They seem, however, to 
be more truly indigenous species than that butterfly, 
their larvse occurring more frequently upon wild 
plants than does the larva of P. Brassicce, and their 
distribution in Europe being more general. Whether 
P. Brassicce is a true native of Northern Scotland 
will probably remain as undecidable a question as is 
the case with certain plants now thoroughly estab¬ 
lished, but probably introduced at some very remote 
period. Analogous cases of the accidental introduc¬ 
tion of butterflies and land molluscs have occurred 
(and are occurring) in North America.
