washed wall. The cells, which had an average depth of 

 i^ inches, were built up of layers in concentric circles, the 

 egg then being laid at the bottom, and the cell, filled up with 

 spiders, about ten in number, is tlien closed, and the whole 

 surface daubed over with mud, so that it should not be too 

 attractive in appearance. The Rev. J. G. Wood, in describing 

 P. jistiLlaria, Gr., a closely allied species, had stated that 

 instead of choosing the plumpest kinds of spiders for her 

 young, this wasp did just the opposite. P. Jiwnilis seemed 

 to take the first that comes ; the contents of a cell exhibited 

 comprised three Epeiridce, five SalticidcE, and two LinyphiidcE. 

 The larvae are full fed in the autumn, and pass the winter 

 in the larval state from November to March ; they turn into 

 pup^ in the spring, and emerge about June. Mr, H. Moore 

 made further remarks with regard to the development of the 

 pigment in the pupae, which he stated seemed to be much 

 slower in our climate, live specimens under observation being 

 susceptible to every change of temperature, a warm day making 

 a considerable difference in their metamorphosis. 



Mr. Billups exhibited six of the seven species of social 

 wasps, of the genus Vespa, indigenous to this country, namely 

 V. crabro, L., V. vulgaris, L., V. gemianica. Fab., V. nifa, L., 

 V. sylvestris, Scop., and V. noi^vegica, Fab., the other species 

 being the rare V. arborea, Smith. 



Mr. R. South exhibited a remarkable specimen oi Argynnis 

 adippe, L. This curious insect was of a pale fawn colour, and the 

 macular ornamentation hyaline, instead of the usual black. 

 On the under surface of the secondaries the silver spots and 

 red dots were quite normal. 



Mr. Auld exhibited three specimens of CallimorpJia hera, 

 L., var. lutescens, Staud., bred from ova obtained from an 

 example of the variety taken in Devon, i8S8. 



Mr. J. T. Williams exhibited an example of Arctia caia, 

 L., with the red of the secondary wings replaced by an 

 orange colour. 



Mr. Rice exhibited a nest and five eggs of the wood-wren, 

 {Phylloscopiis sibilatrix, Bechst) from Sevenoaks, Kent, taken 

 July 17th. The nest, instead of being semi-domed, was 

 cup-shaped, and was built in standing grass about six inches 

 from the ground. The eggs were normal.
