since first taken by Dr. Sharp in 1894, has not been recorded.- — Mr. 

 S. A. Neave, some of the Tabanidae collected during his recent tour 

 in East Africa, on behalf of the Entomological Eesearch Committee 

 of the Colonial Office. He called attention to the male individuals 

 exhibited, and expressed the opinion that their rarity in collections 

 was perhaps due to the fact that they were short-lived. Mr. G. A. K. 

 Marshall observed that probably many of the Fellows present would 

 hardly realize the importance of Mr. Neave's exhibit. Even amongst 

 the English Tabanidie by no means all the males were known, and 

 this sex was hitherto unknown in the large majority of the species 

 then exhibited. — Mr. E. M. Prideaux brought for exhibition seven- 

 teen ova of G. rhaumi.iound in a cluster at Brasted Chart, on April 

 28th, on a shoot of Bhamnus francjula. — Professor Poulton said that 

 he had long been struck, especially in the collections of butterflies 

 received from Uganda and British East Africa, with the immense 

 development of mimicry in Lepidoptera from the forest as compared 

 with the open country. It occurred to him that probably this 

 difference v/as to be accounted for by the difference between the 

 insect-eating animals in these two types of locality, lizards being 

 probably the great vertebrate insect-eaters of the open, birds of the 

 forest. Mr. S. A. Neave said that he had recently had an interesting 

 experience near Entebbe. On January 12th, 1912, at Gabunga's, 

 near Enteblie, he had watched a wagtail, most probably Motacilla 

 capensis, catching butterflies on a small patch of damp sand in the 

 bed of a forest stream. The bird was so tame that he stood within 

 three or four yards of it. In less than half an hour this bird captured 

 and ate nineteen butterflies and failed to catch many others. The 

 butterflies eaten were nearly all small Lycaenids. — Professor Poulton 

 drew attention to a few observations which supported the conclusion 

 that birds possessed the extraordinarily acute and far-reaching vision 

 required by the Batesian and Miillerian theories of mimicry. — The 

 following paper was read : " On the Colour Groups of the Hawaiian 

 Wasps," by Dr. E. C. L. Perkins, M.A., D.Sc, F.Z.S., F.E.S. In illus- 

 tration of the paper. Prof. Poulton exhibited the specimens referred to 

 by Dr. Perkins. The colour-groups vi^ere arranged in the order of the 

 islands, from Kauai in the north-west to Hawaii in the south-east. 



Wednesday, June 5th, 1912. — The Eev. F. D. Morice, M.A., 

 President, in the chair. — Mr- Henry Francis Carter, Assistant 

 Lecturer and Demonstrator in Medical and Economic Entomology, 

 Liverpool School of Tropical Medicine, University of Liverpool, 

 was elected a Fellow of the Society. — The President announced 

 that it was requested that for the future the names of intending 

 exhibitors should be handed in at the beginning of the meeting, 

 in order that they might be called upon from the chair. — The Eev. 

 G. Wheeler read the follovv'ing report of the Committee on Nomen- 

 clature : — "The Committee appointed on April 3rd, 1912, to con- 

 sider the subject of nomenclature, and report to the June meeting 

 with a view to the coming International Congress, has endeavoured 

 to deal carefully and minutely with the matter entrusted by you to 

 its attention. In accordance with the powers conferred on members 

 by resolution of the Society, they added Mr. L. B. Prout to their 

 number after their first meeting. Your Committee probably thus
