Mr. Smith observed that the bees exhibited were a species described by him in the 

 last part of the ' Proceedings of the Linnean Society,' by the name of Trigona laevi- 

 ceps; and that Mr. Parish was quite right in supposing it had no sling, as, like all

 Clark that a species of this genus was excessively abundant in Brazil, forming its 

 nests in banks. 



The Secretary read some notes on Australian Lepidoptera and their larvae, com-

 Islands, near New Guinea. 



Mr. Staiuton read a paper intituled " On the Aberrant Species hitherto placed iu
