name and address, written plain, as I 
cannot send the pupa; till he does? The 
letter is headed “ 4, Royal Exchange 
Buildings.” I cannot malce out the 
sender’s name. — W. Barren, King's Old 
Gateway , Cambridge. 
No Duplicates. — I am rather surprised 
at the number of applications I have 
received for Sphinx Convolvuli , &c. My 
few spare uninjured specimens are already 
promised to friends, and as I cannot pos- 
sibly answer all the letters I have re- 
ceived, I shall be glad if my numerous 
correspondents will consider this notice 
in the light of a polite reply. — R. W.

THE GEOGRAPHICAL DISTRIBUTION 
OF OUR BUTTERFLIES. 
Whilst the subject is still fresh in 
the minds of our readers we should 
be glad of a few observations. For 
instance, how many of our Rhopalocera 
occur in the North of Ireland — at 
Belfast, for instance. Entomologists 
reside at Belfast; surely they can pre- 
pare local lists of their Diurnal Lepi- 
doptera. 
What is the Northern limit of Leu- 
cophasia Sinapis P We heard last sum- 
mer that the insect had occurred near 
Perth, but on making strict enquiry 
on the subject, the accuracy of the fact 
appeared problematical ; indeed, we 
have no certain evidence of Sinapis 
occurring in Scotland. It occurs, we 
know, in the English Lake District, 
and near Carlisle. Collectors at the 
Bridge of Allan who have turned up 
Thecla Quercus have not performed a 
similar operation on L. Sinapis. 
Polyommatus Corydon and Adonis 
are chalk insects ; Adonis has been 
found on the lime-stone at Torquay, 
but we have not heard of its occurring 
elsewhere off the chalk. But do Cory- 
don and Adonis follow the chalk 
northwards into Yorkshire ? Do they 
occur at Flamborough Head? If not, 
where do they stop ? 
There are many other interesting pro- 
blems which we should be glad to 
have solved by competent observers.

FOREIGNERS. 
To the Editor of the ‘ Intelligencer.' 
Sir, — Really what you said last week 
about “Foreigners” is too bad, at least 
so far as regards some of the species 
mentioned. For Pieris Daplidice, it is 
true, there may be less to be said than 
for the other victims you have selected, 
but the case is “not proven” even 
against it; and because it is rarely cap- 
tured it must, forsooth, be set down as 
a refugee from France, and no true 
Briton. I feel that I have a right to 
say, “ How do you know that it does not 
occur in Kent and Sussex every year ?” 
and if seen at all by collectors it may 
easily be deemed one of the common 
whites, which none but juveniles cap- 
ture. Why I know that last year a 
youngster who was only a beginner
