The Zoologist— March, 1868. 1143 



Mr. F. Smith exhibited specimens of the Australian form of Pyrameis Cardui, 

 sent by Dr. Bennett to Dr. Gray, " taken in November, 1860, when off Cape Otway, 

 on the Australian Coast; multitudes of them were about the P. and 0. Company's 

 steamer ' Jeddo,' alighting in numbers on board, and were captured." 



Prof. Westwood remarked that the butterfly in question had been recently separated 

 from Pyrameis Cardui by Prof. M'Coy, and described under a new name. (See Proc. 

 Ent. Soc. 1867, p. lxxxvii.) 



Mr. Trimen exhibited a specimen of Apatura Ionia, a rare species from Asia 

 Minor, placed by some authors in tha genus Vanessa, by others in Pyrameis. 



The Hon. T. De Grey exhibited Hypercallia Christierninana (see Proc. Ent. Soc. 

 1867, p. xcii), captured between Shoreham and Sevenoaks, in the locality where the 

 insect was a few years ago taken by Mr. W. Farren. Also Acidalia rubricata and 

 Opostega reliquella, ZelL, both taken in Norfolk in 1867; see Ent. Ann. 1868, p. 131 ; 

 with reference to Mr. Stainton's remarks there published, on the swarming of Opostega 

 salaciella, Mr. De Grey added that he also had found that insect in such considerable 

 numbers together, that the term "swarming" was not inappropriate. 



Mr. Hewitson communicated a note on the date of publication of Dr. Felder's 

 second volume of the ' Reise der Novara,' a question of some importance with reference 

 to the priority of nomenclature of numerous species of butterflies (see Zool. Record, 

 toI. iii. p. 433, and Trans. Ent. Soc. 3rd series, vol. v. p. 471). Mr. Hewitson made 

 several applications for the volume, either with coloured or uncoloured plates, at the 

 beginning of 1867, through Messrs. Williams and Norgate, who informed him that 

 they were unable to procure it from the bookseller in Vienna. Nevertheless the work 

 (i.e. the text, with uncoloured plates) was really published at the latter end of 1865. 

 Dr. Felder had written to him to the effect that the ' Reise der Novara ' was produced 

 by and at the expense of the Imperial Academy of Science, and was issued by the 

 Academy with uncoloured plates; coloured plates were not kept ready for sale, and 

 copies were only coloured to order, which fact was stated on the cover of the volume : 

 if any one had applied at the Academy, or to the bookseller of the Academy, at the 

 latter end of 1865, for the second volume with uncoloured plates, he could have been 

 supplied with 400 copies. 



The President also read a letter to the same effect from Dr. Felder, who, in 

 corroboration of the above statements, enclosed a letter from Herr Carl Gerold, the 

 bookseller of the Imperial Academy, explaining that the reason why the work had not 

 been supplied when ordered by Mr. Hewitson was, that the only order he had received 

 was for a coloured copy; he had never received any order from England for an 

 uncoloured copy. 



Sir John Lubbock communicated a letter from Dr. Signoret, dated Paris, 

 January 4, 1868, of which the following is a translation: — 



"At the Meetings of the 5th and 19th of November, 1866 (Proc. Ent. Soc. 1866, 

 pp. xxxii. xxxvi.), mention was made of the Aphis which lives in the galls of the elm, 

 and it was spoken of as an object almost unknown at the present day, Geoffroy, 

 Reaumur, De Geer and Et. Geoffroy (1764) being the only authors cited as having 

 treated of this insect. It would be unfortunate for Hemipterology if that branch of 

 Natural History had since that time fallen into oblivion, but it is not so, and to begin 

 with I have only to cite Mr. Francis Walker, who speaks of it in his List of
