themselves to ibe narrow limits of their island, but to extend their rang^e of study to the 

 European forms, the author gave the results of his own collecting at Boulogne-sur-Mer, 

 Pierrefonds in the Forest of Compiegne, in the neighbourhood of Paris, at Neufcliatel 

 and Thuu ; and, finally, expressed his desire to supply information to students of 

 European butterflies, either by indicating localities, recommending useful works, or 

 furnishing specimens of species which he had met with in sufficient plenty.

Notice of Subjects for Discussion. 



The President mentioned that the Council had been considering whether any and 

 what steps were practicable in the way of giving notice beforehand of papers intended 

 to be read or subjects introduced for discussion at the Meetings of the Society. If 

 such notice could be given, members would come better prepared for the consideration 

 of tbe question, and the interest and scientific value of tbe Meetings would be increased. 

 A compulsory rule, that notice must be given, would stifle rather than promote discus- 

 sion, if indeed it would not altogether exclude many subjects, which were, according 

 to the present practice, incidentally discussed on the exhibition of some specimen or 

 object of interest, and which exhibition it was that sugj|;ested and gave rise to the dis- 

 cussion. These incidental conversations, when confiued within proper and reasonable 

 limits, formed one of the most valuable and interesting features of the Meetings, and 

 it was impossible to require previous notice of these, since Members themselves often 

 might not know until the very day of Meeting whether they would be able to attend, 

 or if so what insects they would have to exhibit. All that tbe Council could hope for, 

 and what he had been desired by the Council to request, was that, in future, when any 

 member intended to read a paper on or otherwise bring forward any subject of general 

 interest at a particular Meeting, he would announce the subject at the previous 

 Meeting, if possible, or subsequently at the earliest period to the Secretary, who would 

 give such publicity or notice as under the circumstances might be practicable.

Argynnis Lathonia in the Isle of Wight. — In the November number (Zool. 9817) 

 I read that Dr. Wallace had seen a specimen of Argynnis Lathonia near Colchester 

 but that he did not succeed in capturing it. I have beeu mr)re fortunate, as I took a 

 very fresh one in my garden on the 20lh of October, and I have since lieard thai four 

 others have been taken near Ventnor, after that date. These captures have a peculiar 

 iuterest to us of this island, because in the list of Diurnal Lepidoptera, compiled by 

 that accurate entomologist, Mr. A. G. More, and published by him in that best of all 

 works on every subject of interest connected with the island, edited by the Rev. E.
