ings appeared to act as a stimulus to the production of a colour 

 which corresponded with that which the leaves would sub- 

 sequently assume. Mr. Poulton further stated that he had more 

 recently exposed the larvae of Halias prasinana to white 

 surroundings, and had obtained a white and a very light yellow 

 cocoon — far lighter than the lightest of those met with upon 

 leaves. The larva which spun the white cocoon had previously 

 begun to spin a brown one upon a leaf, but upon being removed 

 to white surroundings it produced white silk. Mr. Stainton 

 suggested that larvae should be placed in green boxes, with the 

 view of ascertaining whether the cocoons would be green. He 

 understood that it had been suggested that the cocoons formed 

 amongst leaves became brown because the larvae knew what 

 colour the leaves would ultimately become. Mr, Poulton said he 

 felt convinced that the whole process was entirely involuntary, and 

 that the susceptibility had arisen through tlie action of natural 

 selection. Tiie discussion was continued by Mr. Waterhouse, 

 Dr. Sharp, Mr. McLachlan, and others. Mr. Klein read " Notes 

 on Ephestia kuhniella," and exhibited a number of living larvae 

 of the species, which he said had been recently doing great 

 damage to flour in a warehouse in the East of London. Mf. A. 

 G. Butler contributed a paper " On the species of the Lepidop- 

 terous genus Euchromia ; with descriptions of new species in the 

 collection of the British Museum." Lord Walsingham commu- 

 nicated a note substituting the generic name Honionymus for the 

 generic name Ankistrophorus, — which was preoccupied, — used in 

 his " Revision of the genera Acrolophus and Anaphora,'' recently 

 published by the Society. Mr. Waterhouse announced that at 

 the December meeting he would exhibit a series of diagrams of 

 wings of insects, and make some observations on the homologies 

 of the veins. — H. Goss, Hon. Secretary.
