Emmett, 2nd Lieut., East Surrey Regt., c/o Messrs. Cox and Co., 16, Charing 

 Cross, London ; and F. H. Gravely, The India Museum, Calcutta, were elected 

 Fellows of the Society. 



The death was announced of the Rev. E. N. Bloomfield, M.A., one of the 

 oldest Fellows of the Society. 



Mr. C. B. Williams exhibited the larva, cocoon, and male and female adults 

 of a dark olive-chocolate variety of Lasiocampa quercus, and read notes, 

 Dr. F. A. Dixey, drawings of the specialised scales from the " greasy patch" on 

 the fore-wing of Ornithoptera priamus f. euphorion, Gray, J , and from the fold of 

 the hind-wing of Cosmodesmus macleayanus, Leach, $ , C. sarpedon f . choredon, 

 Feld., $ , C.eurypylus f. lycaonides Rothsch., (?,and G. enrypylusi. lycaon, Feld., 



$ . Mr. S. A. Neave, some flies of the Asilid genus Hyperechia from Mlanje, 

 Nyasaland, and also nine examples of three species of Hyperechia captured 



'with prey," pointing out that in every case the prey is Hymenopterous. Prof. 

 Poulton drew attention to an observation sent to him by Miss Margery G. 

 Farnell, writing April 15th, 1914, from Allerford, Somerset : — " Suddenly on a 

 rather damp path and flowerbed a wriggling mass of Tipulid larvae appeared. 

 They are there in millions. Yesterday we swept up two barrows full and 

 gave them to the trout, hoping they will devour them. Fresh ones wriggle to 

 the surface every minute." Prof. Poulton read a record of observations, received 

 from Mr. W. A. Lamborn, on the method by which Tachinid flies escape 

 from the mud cells of Eumenes, and on the habits of the wasp, Belenogaster 

 junceus, F., and the attacks of Tachinid flies upon it. He also gave an account 

 of a correspondence bearing upon the Association between fungi and ants, and 

 read letters bearing on Entomology in Tropical Africa. The following papers 

 were read, both being illustrated with the Epidiascope :—" New species and 

 sub-species of Pierinse," by F. A. Dixey, M.A., M.D., F.R.S., Fellow of Wadham 

 College, Oxford ; " On the Taxonomic Value of the Genital Armature in Lepi- 

 doptera," by G. T. Bethune-Baker, F.L.S., F.Z.S., President of the Entomological 

 Society of London. — Geo. Wheeler, Hon. Secretary.

Turning now to the wanderings of Danaida plexippus eastward 



from the American Continent, we are not surprised to find that at the 



Bermudas, the first island group encountered in this direction, the 



butterfly has been long established as a resident, and together with its
