obtained from a female taken in the New Forest. Mr. Dennis, varieties of Lyccena 

 Corydon, Fb., and Polyommatus Phlceas, L. Mr. Turner, a variety of Hypsipetes 

 sordidata, Fb., also dark forms of Boarmia gemmaria, Brahm., from Ashdown Forest, 

 and specimens of Cabera rotundaria, Haw. A discussion ensued as to whether this 

 was a distinct species or only a variety of C. pusaria, L. Mr. Carrington mentioned 

 that several specimens of Catocala fraxini, L., had been recently taken. — 

 H. W. Baekee, Hon. Sec. 



Entomological Society of London : Sept. 4th, 1889. — H. J. Elwes, Esq., 

 F.L.S., Vice-President, in the Chair. 



Prof. C. H. Fernald, of Amherst, Mass., U.S.A., and Mr. C. J. Fryer, of Emscote 

 Road, Warwick, were elected Fellows. 



Mr. G-eorge T. Baker exhibited two remarkably dark specimens of Acronycta 

 ligustri taken near Llangollen. 



Mr. P. B. Mason exhibited and remarked on a collection of Lepidoptera which 

 he had recently made in Iceland. The following species, amongst others, were 

 represented, viz. : — Crymodes exulis, Triphcena pronuba, Noctua conflua, Plusia 

 gamma, Larentia ccesiata, Melanippe sociata, Coremia munitata, Phycis fusca, and 

 Crambus pascuellus. 



The Rev. Dr. Walker also exhibited a number of Lepidoptera, Diptera, and 

 Hymenoptera, recently collected by himself in Iceland. The collection included the 

 following, viz. : — Crymodes exulis, Noctua conflua, Larentia ccesiata, Coremia muni- 

 tata, Culex pipiens, Scatophaga stercoraria, Calliphora erythrocephala, Helophilus 

 grcenlandica, Bombus terrestris, &c. 



Mr. W. White exhibited, on behalf of Mr. Gh C. Griffiths, a specimen of 

 Nephroma Hippia, Fab., var. gcea, Feld., which he believed to be hermaphrodite. 

 He also exhibited, for comparison, a female of the same species. A discussion on 

 hermaphroditism ensued, in which Mr. Distant, Mr. Elwes, Mr. McLachlan, and 

 Mr. Baker took part. 



Dr. Sharp exhibited specimens of Cychramus luteus and fungicola, auct., and 

 stated that they are the sexes of one species, C. luteus being the male, C. fungicola 

 the female. In working through the Central American Cychramini, he had found 

 that in some genera the males differed greatly from the females in size and sculpture ; 

 but this was not a constant character, for in some species, while certain males scarcely 

 differed from the females in these respects, others were so different that they would 

 scarcely be recognised as belonging to the same species. 



Mr. Edward A. Butler exhibited specimens of Platymetopius undatus, Deg., 

 from Ewhurst, Surrey. He remarked that the species was recorded as having been 

 once previously taken near Plymouth by the late Mr. John Scott. 



Mr. G-. T. Baker read a paper entitled " On the distribution of the Charlonia 

 group of the genus Anthocharis." Mr. Baker stated that the species, six in number, 

 of this small division of the genus Anthocharis formed a very natural and closely 

 allied group, presenting many points of interest, both in their relationship to each 

 other and in their geographical distribution, which extended from the Canaries on 

 the west to the valley of the Indus on the east. The author's theories as to the 

 causes of the present distribution of the group, which were based on geological 

 data, were discussed by Mr. Elwes, Mr. McLachlan, Mr. Distant, and Mr. Stainton. 



The Chairman read a paper entitled " On the genus Argynnis," which gave rise 

 to a discussion, in which Mr. Distant, Mr. Jenner Weir, and Prof. Riley took part. — 

 II. Goss, Hon. Secretary.
