Entomological Soctbtt of London : Wednesday, April 6th, 1910. — 

 Mr, H. Rowland-Brown, M.A., Vice-President, in the Chair. 



Ml-. Horace B. Browne, M.A., of 118, Sunny Bank, Hvdl ; Mr. William George 

 Dawson, of 31, King's Gardens, West End Lane, West Hampstead, N.W. ; Mr. 

 Alfred Nander Hedges, of 42, Kensington Park Gardens, W. ; the Rev. 

 Hubert George Stanley, of Marshfield Vicarage, Cardiif; and Mr. Rupert 

 Stenton, of Soi\thwell, Notts. ; were elected Fellows of the Society. 



Mr. W. G. Sheldon exhibited several series of the Initterflies taken by him 

 last July in the Hohe Tatra region of the Cai-pathians, Eastern Hungary. They 

 included examples of Melitsea dictynnoides, Hormuzaki, with M. aurelia and 

 M. dictynna for comparison ; Brenthis -pales var. arsilache from the forest zone 

 at 3000 feet, and a form of B. pales from 5000 feet, with the upper-side 

 approaching in colour and markings to var. arsilache, but of smaller size, the 

 under-side being typical ; also Swiss examples for comparison : Parnassixis 

 apollo var. carpaticus, Aigner ; Erebia medusa, var. liipjpomedusa, E. ligea, and 

 Ccenonympha hern. The Rev. G. Wheeler expressed a decided opinion that M. 

 dictynnoides constitutes a good sjiecies, and is not a form of M. aurelia. Mr. P. 

 Harwood, an example of Strangalia revestita, taken on a flower-head near 

 Andover in 1909. Mr. W. F. T. Rosenberg, (a) a "combination" consisting of 

 a Nymphaline butterfly, Euphxdra ruspina, and three species of moths 

 belonging to as many different families, viz., Phsegorista. similis (Hypsidsa), 

 Xanthospilopteryx poggei (Agaristidw), and a Geometer, Aletis helcita. These 

 insects bore a close sujierficial resemblance to each other in colour and pattern 

 of markings, the wings being tawny-oi'ange, with black marginal borders and 

 white apical and marginal spots : (b) a, pair of the Nymphaline butterfly, 

 Harma theodota, a strikingly dimorphic species, the female of which bears some 

 resemblance, especially on the iipper-side of the hind-wings, to a moth, 

 Nyctemera hesperia, of the family Lymantriadse ; and (c) five species of Planema 

 (family Acrseidse) and an equal number of species of Pseudacrsea (family Nym- 

 phalidve) mimicking them, the superficial resemblance being very close in each 

 case. Special attention was called to the specimens of Planema plagioscia, the 

 males of which, with tawny bands on the fore-wings, are mimicked by the 

 males of Pseudacrsea hobleyi, while the females of the Planema, with white 

 bands are mimicked by the females of the same species of Pseudacrsea. Mr. 

 H. St. J. Donisthorpe, examijles of Methoca ichneumonides, parasitic on the 

 larva of the Tiger Beetle, taken by him at Blackgang Chine, in the Isle of 

 Wight, where its host would be C. germanica ; also an example of Ptinella 

 hritannica, Mat., found in a mole's nest at Burwell Fen last month. This is only 

 the third British specimen that has yet been recorded, and apparently the fourth 

 only in Eiu'ope, one having been reported from France. 



Mr. Norman H. Joy, M.R.C.S., read a paper " On the behavioui' of Coleoptera 

 during Floods," and exhibited living specimens to illustrate the remarkable 

 power of Dianous coerulescens in " skimming " on the surface of water. The 

 following papers were also read : — " A Revision of the genus Diplatys, Serv.," 

 by Malcolm Burr, D.Sc, F.L.S., F.Z.S., &c. "On the Gcometridse of the 

 Argentine Republic," by Louis B. Pi-out, — H, Rowland Brown, M.A., Hon. 

 Secretary,
