food-plant abounds. In its new home the species has 

 increased to such an extent that tliis season 1 found it quite 

 common, and have no doubt tliat 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 

 larvae ; 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 "prools." — IV. H. Harwood; St. 

 Peter's Colchester. 



Argynnis Lathonia and Catocala Fraxini 7iear Canter- 

 hiiry. — 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 

 1st 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 Larva of Saiurnia Carpini Hyhernate? — In 

 reference to the query in the October number of the 'Ento- 

 mologist' (Entom. vii. 227) by Mr. Robinson-Douglas, as to 

 whether the larva; of Saturnia Carpini hybernate, I may state 

 that in the spring of this year 1 had cocoons of S. Carj)ini, 

 from which the perfect insect emerged, and that 1 obtained
