successful were given. He then passed on to consider the prepara- 

 tion of the perfect insect and its gall for the cabinet. In conclusion, 

 he enumerated the principal points which require to be noted in a 

 perfect and complete description of the development and economy of 

 the species, dwelling on the importance of the last or anal segment 

 of the larva, from the tubercular prominences often found upon it, a 

 character often overlooked by previous students. In the imago he 

 pointed out the extreme value of the characters of the antennee, not 

 only from their importance in fixing the genus, but also because a 

 good specific character existed in them. He urged upon the students 

 the necessity of descriptions of the imago being taken from the 

 living insects, and that those made from dead and dried examples 

 were valueless. The paper was illustrated with diagrams and draw- 

 ings of the principal forms of galls, and also of the larva, pupa, and 

 imago of the insect.

SPECIMENS EXHIBITED. 



Mr. Allan exhibited a collection of mosses from Brazil, made by 

 Mr. John Weir, formerly of the Glasgow Botanic Gardens. A few 

 of the species are identical with British mosses, but the great 

 majority are not only specifically but generically distinct.
