THE ENTOMOLOGISTS WEEKLY INTELLIGENCER. 
been perfectly aware of their spurious- 
ness. 
Among the more scrupulous (?) dealers, 
however, quibbles — more dangerous than 
falsehoods — are sometimes resorted to; 
thus, for instance, a person says, “ Here 
is a specimen of C. Delphinii, which was 
taken at Windsor.” No getting out of 
that, thinks the lucky (?) purchaser; but 
he is wrong, for all that ; a comma placed 
after specimen will make “all the dif- 
ference,” or if the word Delphinii be re- 
peated, to make the sentence compre- 
hensible, the “which” would refer to a 
previous capture at Windsor, and the 
specimen in question merely to the spe- 
cies; hut it is not elegant to repeat 
Delphinii , as the English language 
abhors repetition, except perhaps in the 
‘ Song of Hiawatha.’ 
But 1 have begun at the wrong end ; 
my intention was to add a few words in 
favour of the general assumption that 
Daplidice , Lalhonia and Antiopa are 
resident British species. 
With respect to the former, a late 
communication from the Rev. William 
Henry Hawker (Intel, vi. 1H6) throws 
considerable light upon the point, and 
I also think that Mr. Harding’s ob- 
servations (however imperfect) somewhat 
assisl our views. I say “ imperfect,” be- 
cause, after mentioning bis first capture, 
and leaving us to infer that he has made 
subsequent ones, he stops short. Now' it 
seems to me the more authenticated cap- 
tures we have recorded the greater will 
be the disposition to believe it a “ resi- 
dent.” I fancy your readers would take 
it kindly if Mr. Harding would enumerate 
at any rate the number of his captures of 
British Daplidice. 
Regarding Lalhonia the case seems a 
strong one, as it is well known that it 
has been and is to be collected annually 
in several localities, one of which I know 
to be Dover. 
But Antiopa, in my opinion, has the 
strongest claims of all; the larva has 
been taken here, I believe ; the perfect 
insect (if not always caught) is seen 
regularly every year in more than one 
inland spot ; and I would ask, How is it 
that (if blown over) the typical yellow- 
bordered species ot the Continent scarcely 
ever (never perhaps) occurs with us, 
whereas the white-bordered variety seems 
almost peculiar to England. 
Yours, &c.,

THOUGHTS ON GEOGRAPHICAL 
DISTRIBUTION. 
BY MR. C. S. GRKGSON. 
Geographical distribution! what does 
it mean? I confess I cannot under- 
stand how it applies in this little 
England of ours. It seems to me that 
where favourable districts obtain, thera 
the Butterflies are — South or North. 
As an instance, who ever suspected 
that Thecla Betulce was a common North 
Lancashire insect until Mr. Mason found 
it around his residence at Grange? and 
I am free to admit I was surprised when 
he showed me a great lot of Polyom- 
malus Corydon, stating that it was by 
far the commonest Blue he took. 
P. Corydon should be a chalk insect, 
but Grange is a lime- stone district; here, 
too, in this snug little corner, Erebia 
Blandina is a common garden butterfly,
