Society.” This was carried by acclamation, and Mr. Bates was thereupon admitted 
as a Member, and signed the Obligation Book. 
Alteration of Bye-Laws ; Notice of Special Meeting. 
Notice was given that, in consequence of a requisition presented to the President 
and Council, signed by six Members, a Special General Meeting would be held on 
Monday, the 25th January, 1864 (the next Anniversary), at 7 p.m., for the considera- 
tion of certain alterations in the Bye-Laws specified in the requisition, and the object 
of which was, to abolish the Library and Cabinets Committee and the Publication 
Committee, and to vest their powers and duties in the Council, to change the title of 
Curator to that of Librarian, and to repeal the clause by which it is enacted that no 
eresident in Great Britain shall be an Honorary Member of the Society. 
Exhibitions, &c. 
The President exhibited the nest of Trigona carbonaria referred to in the ‘ Pro- 
ceedings’ of the last Meeting; it had been recently received from Queensland, and 
was constructed in an artificial situation, in the interior of a box, by reason of which 
its appearance was probably different from the normal form of the nest; on the upper 
(or free) side was a quantity of matter, of a coralline structure, which was apparently « 
made for the purpose of carrying the nest up to the top of the box, and thereby of 
attaining additional support. Externally the nest seemed to consist simply of rude 
spherjcal honey-pots in contact with one another, or connected by means of the coral- 
like work before alluded to, but the President thought it probable that there was 
comb, more or less irregular, in the interior. It was remarkable that not a single 
female of any of the numerous species of Trigona was known. 
Prof. Westwood remarked upon the extraordinary difference of habit between the 
Brazilian and Australian Trigone; the Brazilian species made hexagonal cells in 
single layers, and the difference was as remarkable as if a species of Apis in England 
were found to make honey-pots like a Bombus instead of the ordinary nest of a true 
Apis. This structural modification was so great as to suggest a doubt whether Trigona 
carbonaria had been rightly placed in the genus Trigona. 
The President also exhibited nests of Deilocerus Ellisii, Curtis, one of the social 
Tenthredinide: the nests had formerly been exhibited by Curtis at the Linnean 
Society, and were figured in vol. xix. of the Linnean ‘ Transactions.’ 
A lively conversation subsequently took place, on the origin or causes affecting 
the hexagonal form of the cells of bees, in which the principal participants were the 
President, Mr. Waterhouse, Mr. Bates and Prof. Westwood. 
The President exhibited specimens of Hyponomeuta padella, which had been 
given to him by one of the assistants in the British Museum, and which were said to 
have been bred from larve feeding on unripe grains of corn. The gentleman in ques- 
tion (to whose general accuracy of observation the President bore testimony) had been 
walking through a corn-field in Suffolk, plucking some of the ears and eating the 
grain, when he noticed an unpleasant taste, and on examination found numerous 
larve feeding on the grain; he had put some into a box, and from them had emerged 
the exhibited specimens of H. padella. It was, however, thought probable by the 
Lepidopterists present that some mistake must have been made as to the identity of 
the larve from which the moths had been raised. 
‘Mr. Bond exhibited a coloured drawing of the larva of Sphinx Convolvuli, of which
