Entomological Society of London: Wednesday, Mcnj 1st, 1912. — Mr. A. 

 H. Jones, Vice-President, in the Chair. 



The Rev. E. Adrian Woodrnffe-Peacock, F.L.S., F.G.S,, Cadney Vicarage, 

 Brig-g, Lincolnshire, was elected a Fellow of the Society. 



Mr. A. H. Jones exhibited three examples of Aglais iirticae, var. ichnusa, 

 showing the absence of scales in the centre of the wings, where the central spots 

 are present in the type. These spots appeared also in one only of the Corsican 

 examples. Also examples of Euchloc damone from Sicily and Asia Minor, 

 showing the difference in the depth of coloiu" of the transverse black streak on 

 forewings and in the tone of colour of undersides. Dr. G. B. Longstaff, a series 

 of twelve specimens (five males and seven females) of the rare white butterfly, 

 Pinacopteryx doxo, Godart {venatus, Butler), from the White Nile. Mr. Alfred 

 Sich, two specimens, with their cases, of Coleophora trigeminella, Fuclis, and 

 one specimen of C. hadiipennella, Dup., with its case for comparison. Mr. W. 

 J. Kaye, three small groups of Ithomiine butterflies that had been taken by 

 himself in S. Brazil, One group consisted of Heterosais nephele edessa, Ithomia 

 drymo, and Leucothyris aquata, all of which had been taken at Guaruja, near 

 Santos, at the end of February and beginning of March, 1910. Another similar 

 group, all belonging to diffei-ent genera, was one made up of Pseudoscada adasa, 

 Pteronymia sylvo, and Hymenitis andromica andania, all of which had been 

 seciu-ed at Castro in Parana at close on 3000 feet elevation. He remarked that 

 these grovips of black and transparent Ithomiine species were always found in 

 rather dark forest countr_v, and it was possible tliat they were simply cases of 

 syncryptic resemblance, rather than mimetic examples of a Miillerian Associa- 

 tion, for these species were invisible at a very sliort distance, and they were all 

 equally adapted to that end. A third small group that was exhibited consisted 

 of a Danaine, Ituna ilione, and two Ithomiines, Thyridia (Methona) themisto and 

 Dircenna dero. All these were also from Castro. Professor E. B. Poulton was 

 of opinion that the forest species as well as the others were connected as 

 members of a mimetic group. Dr. Longstaff, speaking from personal experience, 

 empliasised the invisibility of these Ithomiines on the wing, at a very short 

 distance, in their native haunts. Mr. Hamilton H. Druce, 3 and ? 

 of the new Mimacraea eltringhami, captured by Mr. S. A. Neave in the Bugoma 

 Forest, Unyoro, Uganda ; also another new Mimacraea which he proposed to 

 name costleyi, after its discoverer Mr. Costley-White, from Mlanje, Nyasaland. 

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

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

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

 with nets. Mr. A. E. Gibbs exhibited a drawer of butterflies recently received 

 from Dr. Davis, of Belize, and collected in British Honduras and the neighbour- 

 ing Republic of Guatemala. Mr. G. T. Porritt, specimens of Nemoura duhitans, 

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

 comparison specimens of Nemoura inconspicua, Pict., from Aviemore. 

 Mr. H. M. Edelsten, stems of Carex riparia (received from the 

 Hon. N. C. Rothschild from Berlin) to illustrate the life history of Nonagria
