gigantic size of the female, a new discovery by A. S. Meek, who found 

 this line insect in the north-eastern portion of British New Guinea, 

 at some distance inland from the coast ; and a gynandromorphic 

 specimen of Troides, the only one known of this genus, obtained by 

 Dr. L. Martin in South Celebes. It belongs to T. halvphron, the left 

 side being female and the right side male. — Mr. E. Adkin exhibited 

 specimens of Tortrix pronuhana, Hb., reared in June and July from 

 larvae collected in May, also others reared in autumn from ova de- 

 posited by moths of the June emergence. He concluded that when 

 the habits of the species came to be better understood, it would be 

 found to be practically continuously brooded in this country, as had 

 been shown to be the case in Guernsey. — Mr. L. W. Newman showed 

 long series of MelUcea aurinia, from many localities in the United 

 Kingdom, and Notodonta chaonia, to illustrate the wide superficial 

 variation of the respective species. — Dr. F. A. Dixey exhibited speci- 

 mens of Nycliitona medusa, Cram., and Pseudopontia paradoxa, Feld., 

 observing that a former suggestion of his as to a mimetic relation 

 between them had been confirmed by a letter lately received from 

 Mr. S. A. Neave, at present in the Congo State, w^ho wrote that the 

 two forms " inhabit exactly the same localities, and are barely distin- 

 guisliable from each other on the wing." — Mr. Eowland E. Turner 

 communicated a paper " On Tw^o Diplopterous Hymenoptera from 

 Queensland," and " Notes on ThynnidaB, with remarks on some 

 Aberrant Genera of the Scoliidae." — Mr. Guy A. K. Marshall read a 

 paper " On Diaposematism, wnth reference to some Limitations of 

 the Mlillerian Hypothesis of Mimicry." In this he pointed out the 

 difficulty of accepting the idea of a mutual simultaneous mimicry 

 between two unpalatable species, such as is postulated by the hypo- 

 thesis of Diaposematism. A discussion was begun by Dr. F. A. 

 Dixey and Professor E. B. Poulton, and adjourned to the next 

 meeting. — The General Meeting which followed was adjourned to 

 March 4th. — H. Eowland-Beown, M.A., Hon. Secretary. 



The South London Entomological and Natural History 

 ^ocmiY.— January 9th, 1908.— Mr. E. Adkin, F.E.S., President, in 

 the chair. — Mr. Sich exhibited a specimen of Plodia interpunctella, 

 captured in the Society's rooms. — Mr. Gadge, specimens of Malaco- 

 soma neustria, from Chingford larvae ; one without a rudiment of the 

 right hind wing, and the other with an extremely small left fore 

 wing. — Mr. Turner, Dercas verhuelli, a Pierid near G. rhamni ; and 

 the " map " butterfly, Cyrestis thyodamas, both from the Khasia 

 Hills, India. — Dr. Hodgson and Mr. Grosvenor, series and specimens 

 of Aricia agestis (astrarche), including var. saknacis, ah. obsoleta. ab. 

 alpina, var. artaxerxes, ab. allous, &c., from Eeigate, Sussex, Nortli 

 England, and Aberdeen. — Mr. Adkin, series of Tortrix pronuhana, T. 

 podana, T. heparana, T. rosana, T. forsterana, Si,nd Batodes angustio- 

 rana, reared from larvae taken on Euonymus japonicus at Eastbourne, 

 in May and June, 1907 ; and read a paper entitled, " Further Notes 

 on Tortrix pronubana, including its Life-history in Britain." — Eeports 

 of the various field-meetings held during 1907 were submitted and 

 read. — Hy. J. Turner, Hon. Bep. Secretary.
