In conclusion, I can only hope that 
older and more experienced entomologists 
than myself may continue the “ Cy r bele,” 
at least of our Lepidoptera, more success- 
fully than I have done, and that future 
observation may render the “ Cybele of 
the Sphingina” more complete. I am 
willing to assist in any such undertaking 
as much as I am able. I had no difficulty 
with this paper after carefully studying 
Messrs. Boyd and More’s.

GEOGRAPHICAL DISTRIBUTION OF 
BUTTERFLIES. 
To the Editor of the ‘Intelligencer.' 
Sir, — It may be interesting to some 
of the readers of the ‘Intelligencer’ to 
know that, in other countries, Polyom- 
matns Corydon docs not exhibit the par- 
tiality for chalk which it generally does 
in this. I have seen it in Switzerland, 
not ouly upon the various limestones 
which abound in the Alps, but also upon 
gneiss, mica schists, and other metamor- 
pliic rocks, and even in the plains near 
Lausanne (Canton de Vaud), where there 
is nothing but gravel or molasse for many 
miles. 
I have also been much struck with 
the extensive range of another butterfly, 
late the subject of discussion — namely, 
Argynnis Lathonia. I have seen it at 
every elevation from 1200 to 7000 or 
8000 feet, and I am tolerably certain 
that a specimen flew past me while I was 
sitting on the Col of the Strahlech, a 
spot surrounded with snows and glaciers, 
and some 10,000 feet above the sea. 
Most of the butterflies in Switzerland 
have their ranges tolerably well de- 
fined : e.g. as far as my experience goes, 
you will not find Erebia Cassiope on a 
mountain lower than 6000 feet, but La- 
thonia seems quite indifferent to change 
of temperature. I should be glad if any 
of those who have taken E. Cassiope in 
Great Britain could tell me the eleva- 
tions of the spots on which they have 
taken it. 
Yours, &c., 
Rev. T. G. Bonney.
