GEOGRAPHICAL PROVINCES. 
Of our British Butterflies twenty-fire, 
which all occur in the South-East of 
England, disappear as we advance 
northwards and westwards; fourteen of 
them occur in Ireland, but only five 
reach Scotland. 
The species with the most restricted 
range is Limenitis Sibylla. If a line 
be drawn through Colchester, Epping, 
Winchester and the Isle of Wight, the 
country lying to the right of that line 
will give the province of Sibylla. 
Apatura Iris has a considerably 
wider domain ; it attains Lincoln and 
Leicester, and westward we find it in 
Monmouthshire, on the banks of the 
Severn : the country lying southward 
of a line drawn through these places 
would therefore indicate the province 
of Iris. How far westward this spe- 
cies may occur in Somerset or Devon 
we are not yet in a position to an- 
nounce. 
The province of Iris is shared by 
Aporia Cratcegi, Melitcea Athalia and 
Polyommatus Adonis. Cratcegi, it is 
true, scarcely goes as far North on the 
eastern side of the Island as Lincoln, 
but it reaches fairly into South Wales, 
occurring at Cardiff. Athalia seems 
even to have a more restricted range 
northwards, as Stowmarket and New- 
port Pagnel seem to bound its territory 
in that direction ; but westward it ex- 
tends even to Bideford. The limits of 
Adonis, as at present known, are 
Halton, in Buckinghamshire, Bristol 
and Torquay. 
Three species, which do not extend 
beyond the province of Iris on the 
eastern side of the Island, reach much 
farther to the northward on the western 
side; thus Theda Betulce and Polyom- 
matus Corydon are found in Lanca- 
shire, North of Morecambe Bay, and 
Leucophasia Sinapis frequents the Cum- 
berland Lake District. A line joining 
Peterborough and Ulverstone would 
leave Nottingham, Derby and Man- 
chester to the South ; but have we 
any knowledge that these three species 
occur in all these localities ? The point 
is interesting and requires further elu- 
cidation. 
Vanessa Polyehloros, Argynnis Adippe 
and Nemeobius Lucina attain York on 
the eastern side of the country and 
Carlisle on the Western side. Adippe, 
we believe, has even occurred in the
