had been unable to determine the species, found in the mud under stones in the same 

 locality. 



Mr. MoLachlan exhibited an Acrobasis,nevv to Britain, taken at Forest Hill, which 

 Mr. Stainton had pronounced to be A. rubrotibiella of Mann., a species hitherto 

 only found near Vienna : it is closely allied to A. tumidella, though sufficiently distinct, 

 as pointed out by Fischer-von-Roslerstamm in his illustrated work. 



Mr. Bond exhibited four fine bred specimens of Carpocapsa saltatans, Wcstiv., 

 with the pupa cases and seeds from which they had emerged. 



Mr, Wariug e.xhibited a singular pale variety of Poecilocarapa Populi. 



Mr. Adam White exhibited the flat pupa-case of a Cebrionideous genus from North 

 China, and remarked on the vast field of research still open to entomologists in the 

 transformations of Coleoptera. He also communicated the following : — 



" Mr F. G. Nicolay, a promisiug young naturalist, who lately went to St. Salvador, 

 Brazil, sent over, wi(hiu a week or two of his landing, a box containing the following 

 insects. The list may be not unworthy the notice of the Members, and its publication 

 may encourage youthful entomologists to persevere, and ascend from collecting to 

 observing transformations : — 



Papilio Thoas Vanessa Lavinia 



„ Polydamas Anarta latrophse 

 Heliconia Halia „ Amalthea 



Evides Dianasa Heterochroa Cytherea 



Mechanitis Lysimnia Argynnis Hegesia ? 



Agraulis Vanillaj Didonis Biblis 



„ Julia Polyommatus and three or four 

 Danais Gilippus Hesperise. 



„ Archippus 

 Terias tenella

„ Mana Pbanaeas J asius (very common)

Mr. Tegetmeier observed it was generally believed that pollen was only used as 

 food for the larvse of bees, and not by the perfect insects ; he had, however, frequently 

 observed bees on the alighting-board of a hive, especially in dull weather, eating the 

 pollen from the legs of their companions as they arrived. He had continued the 

 experiments detailed by him at the July Meeting of the Society, with a view of 

 ascertaining the cause of the hexagonal form of the cells of the hive bee, and found 

 that when excavating in a solid mass of wax they always formed cyliuders, but on the 

 sides of the cells approximating they invariably became hexagonal ; he considered 

 therefore that the hexagonal form resulted simply from the cells being constructed with 

 a view to the greatest economy of space, and not from any predetermined plan on the 

 part of the bees. 



Mr. Lubbock remarked that Mr. Darwin had made similar experiments to those 

 described by Mr. Tegetmeier, with precisely the same results. 



Mr. Smith maintained the assertions made by him at the July Meeting that in 

 wasps' nests the cells are constructed of an hexagonal form, and do not acquire it from 

 compression or any other cause. He exhibited the nest formed by the female of Vespa
