224 THE entomologist's record. 



A. Neave described the capture of these specimens. This species in 

 common with several others flics very high, and he said it was often 

 necessary to employ small native boys perched at the tops of the trees and 

 armed with nets. Butterflies from British Honduras and Guatemala. 

 — Mr. A. E. Gibbs exhibited a drawer of butterflies from these localities 

 recently received from Dr. Davis, of Belize. A scarce Plecopteron. — 

 Mr. G. T. Porritt exhibited specimens of Nemnnra duhitans, Morton, 

 taken by Colonel Nurse at West Stow, Suffolk, in June last, and for 

 comparison specimens of Nonoura incnm^piciia, Pict., from Aviemore. 

 Life History of Nonagria nexa. — Mr. H. M. Edelsten, exhibited 

 stems of Care.v riparia (received from the Hon. N. C. Rothschild from 

 Berlin) to illustrate the life history of Nonagria nc.ra, Hb. A scarce 

 Thrips. — Mr. C. B. Williams exhibited a specimen of the male 

 Menalothrip^ nohilh, Bagnall, from Wicken Fen, taken April 11th, 

 1912. This is the largest European species and, since first taken by 

 Dr. Sharp in 1894, has not been recorded. East African Tabanid^e, 

 with many hitherto unknown Males. — Mr. S. A. Neave exhibited 

 some of the Tahanidae collected during his recent tour in East Africa, 

 on behalf of the Entomological Research 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 realise the 

 importance of Mr. Neave's exhibit. Even amongst the English 

 Tahanidae by no means all the males were known, and this sex was 

 hitherto unknown in the large majority of the species then exhibited. 

 A Cluster of Ova of Gonepteryx rhamni. — Mr. R. M. Prideaux 

 brought for exhibition seventeen ova of 6^. rlmmni found at Brasted 

 Chart, on April 28th, on a shoot of Bhamnint fran<mla. Mimicry in 

 the Tropics chiefly characteristic of Forest Areas. — Professor 

 Poulton said that he had long been struck, especia.]ly 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. He read notes bearing on this point 

 from Messrs. C. A. Wiggins, F. J. Jackson and C. F. M. Swynnerton. 

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

 experience of insectivorous birds, near Entebbe. On January 12th, 

 1912, at Gabunga's, near Entebbe, he had watched a wagtail, most 

 probably Motacilla capcnsis, 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 3 or 4 yards of it. In less than balf-an-hour this bird 

 captured and ate 19 butterflies and failed to catch many others. The 

 butterflies eaten were nearly all small Li/raenidae. The Power of 

 Sight in Birds. — Professor Poulton called attention to a few observa- 

 tions which supported the conclusion that birds possessed the extra- 

 ordinarily acute and far-reaching vision required by the Batesian and 

 Mullerian theories of Mimicry. The following Paper was read : — "On 

 the CoIourCIroupsof the Hawaiian Wasps, "by Dr. H. C.L.Perkins, M. A., 

 D.Sc.,F.Z.S.,F.E.8. In illustration of the paper, Prof. Poulton exhibited 

 the specimens referred to by Dr. Perkins. The Colour-groups were 

 arranged in order of the islands, from Kauai in the N.W. to Hawaii in 

 the ?).E. — .finic5th, 1912.— Mr. Henry Francis Carter, Liverpool School 

 of Tropical Medicine, University of Liverpool, was elected a Fellow of the
