Mr. Rayward exhibited a series of Hybcrnia marginaria 

 (progemmaria) from Liverpool and Surrey. The former were 

 all dark, both males and females ; the latter from Wimbledon 

 and Croydon showed moderate dark suffusion in the males, 

 and some of the females were quite as dark as those from 

 Delamere Forest. One female from Wimbledon was 

 extremely light. 



Mr. Sich exhibited living imagines of Lithocollctis sylvella 

 from Cookham, Berks. The leaves of maple, the food plant 

 of the larvae, were collected in October, 1905, and placed in 

 flower-pots half filled with silver sand, and plunged in the 

 earth in the open. The pots were covered with muslin. 



The remainder of the evening was devoted to an exhibition 

 of lantern slides. Mr. Main showed slides of the larvae of 

 Agrotis ashworthii, Nisoniades tages, Limenitis sybilla, Apatura 

 iris in hibernation on a leaf of sallow; the larva of a stag- 

 beetle, and the pupa of a sawfly taken from a cocoon found 

 on hawthorn. Mr. Tonge, photographs of the extensive 

 colonies of the daffodil which grow near Balcombe, Sussex. 

 Mr. Lucas, a series of slides from Mr. Hamm illustrative 

 of the protective resemblance shown in the resting habit of 

 Tcphrosia biundularia; T. luridata (extcrsaria), Rumia cratccgata 

 (hitcolata), Mclitaa aurinia (artemis), Parargc egcria, Cidaria 

 miata, and Dimorplia versicolor, with others by himself. Mr. 

 West, of Ashtead, slides illustrating sections of various kinds 

 of woods, slides of the freshwater hydra (a most difficult 

 subject to photograph), and illustrations of various favourite 

 collecting localities. Mr. Dennis, slides of the male and 

 female flowers of the mistletoe, various trees showing leaf 

 scars and winter buds. Mr. N. Clark, a series of slides of 

 bacteria and bacilli taken with a T V in. lens. A discussion 

 took place on photography as used to show protective 

 resemblance. It was remarked that the impression recorded 

 by the sensitive plate did not always agree with the impres- 

 sion formed by the human eye.

Mr. H. Main exhibited a living scorpion (Scorpio curopecus) , 

 sent to him from S. Maxime, South France, by Dr. Chap- 

 man. It had fed greedily on flies, and had also devoured a 

 Picris rapcE. He also showed a nymph of the European 

 Mantis, Mantis rcligiosa, obtained from the same locality. 



Mr. Lucas exhibited a number of species of the mosses
