dopfera, including a specimen of tlie very rare Ismene Helios from 

 Bokhara, which Mr. Doubleday refen-ed to the genus Parnassius, 

 agreeing therewith in the general arrangement of the veins of the 

 wings and spur of the anterior tibiae, although the palpi were 

 rather more elongated and the hind wings marked beneath as in 

 Pontia Daplid'ice, with which it also agrees in the general form of 

 the wings. 



Likewise a number of minute Coleoptera very carefully set out 

 upon small square pieces of talc by M. Waga of Warsaw, and so 

 arranged, by sticking a number of pieces of talc on one pin, as to 

 pack up in very small compass. Likewise a number of Cater- 

 pillars very skilfully preserved by M. Graeff of Berlin (Jeru- 

 snlemme Strasse, No. 18), and sold at very reasonable prices. 



Mr. Westwood exhibited specimens and drawings of the 

 Cochineal insect in its various states, which he had received from 

 Mr. Augustus Faber, by whom it had been brought from Madeira. 

 He had ascertained that its habits were unlike those of the 

 ordinary Coccidce, as the females brought forth their young alive, 

 and which were not deposited beneath the body; moreover the 

 male pupje were enclosed in a bag-like cocoon with the lower end 

 open, out of which the imago escapes backwards with the wings 

 laid over the head ; thus as well as in other respects warranting 

 its generic separation as proposed by him in his " Litroduction to 

 the Modern Classification of Insects." A memoir had been lately 

 published in the Pharmaceutical Journal on this insect, in which 

 various erroneous observations had been made. Li reply to a 

 question by Mr. Newport, Mr. Westwood observed further that 

 the circumstances which he had detailed took place in the ordinary 

 temperature of the atmosphere during the preceding summer and 

 autumn, the plants having been kept in a chamber without a fire. 



The President read an extract from a letter from R. Stewart, 

 Esq., one of the Members of the Torquay Natural History 

 Society, on the subject of exchanges of Insects to be made 

 between the Societies ; whereupon some observations were made 

 by Messrs. Saunders, Douglas and Doubleday as to the mode 

 adopted by the Botanical Society for distributing their duplicates 

 amongst the members, with a view to the adoption of a similar 

 plan in this Society, which Mr. Saunders urged especially with 

 regard to English Insects. 



Mr. Newport exhibited specimens of the transformations of 

 the genus Meloe, viz. the larvae in the earliest stage of M, violaceus, 

 the full grown larvae, the nymph and imago of M. cicalricosus, 

 which latter he had reared. In their earliest stage the larvae of
