food-plant abounds. In its new home the species has 
increased to such an extent that this season I found it quite 
common, and have no doubt that it will go on increasing 
rapidly. Of course it could not do so without laying eggs; 
and if eggs were found, would Mr. Clifford, or anybody else, 
consider that fact a sufficient proof that the species was 
native to the locality? Again, when collecting at Old Hall 
Wood, near Ipswich, some time ago, I was told by an 
Ipswich collector, whom I met there, that Limenitis Sibylla 
did not occur in that particular wood till it was introduced by 
an old collector, named Seaman, who brought a number of 
living specimens from St. Osyth, and turned them down there. 
Now, is it not possible that somebody may have “turned 
down” continental Niobe in Kent, which have been “ turned 
up” by somebody else? People on the Continent could 
probably supply their English correspondents with eggs or 
larve; and if these were placed in favourable situations the 
perfect insects might reasonably be expected in due season. 
I do not, however, wish to express any definite opinion 
as to this particular case of Niobe; for, notwithstanding the 
scepticism to which Mr. Clifford alludes, its occurrence in 
Kent may possibly be quite genuine; and my object in 
writing is to warn entomologists against allowing themselves 
to be deluded by sham “ proofs..—W. H. Harwood; St.

Argynnis Lathonia and Catocala Fraxint near Canter- 
bury.—I took a very fine specimen of Lathonia on the 3rd 
of August, also one on the 13th, three on the 23rd, one on the 
Ist of September, two on the 7th, and two on the 15th, at 
Pelhatham and Swarling Downs. Also one specimen of 
C. Fraxini in Pine Wood, where I have taken, in all, six in 
seven years, but none good till this one, which I took on the 
26th of September, almost equal to bred. I have showed it 
alive to three or four gentlemen.—G. Parry ; Church Street,

Do the Larve of Saturnia Carpini Hybernate ?—In 
reference to the query in the October number of the ‘ Ento- 
mologist’ (Entom. vii. 227) by Mr. Robinson- Douglas, as to 
whether the larve of Saturnia Carpini hybernate, I may state 
that in the spring of this year ] had cocoons of 8S. Carpini, 
from which the perfect insect emerged, and that I obtained
