 Vice-President, in the chair. — -Mr. E. Stewart McDougall, M.A., 

 D.Sc, E.E.S.E., of Edinburgh University ; and Mr. Hugh Frederick

 of congratulation to Mr. Eoland Trimen, F.E.S., from the Entomo- 

 logical Society of London, on the occasion of the award to him of 

 the Eoyal Society's Darwin Medal, was read and approved.— The 

 Vice-President announced that he had received from Dr. A. Feynes, 

 a Fellow recently elected, and exhibited on his behalf, four boxes con- 

 taining an admirable collection of North American Aleocharine 

 Coleoptera, which the donor had offered most kindly to the Society. 

 In the absence of any collections belonging exclusively to the Ento- 

 mological Society of London, however, he had asked Dr. Feynes to 

 authorize a transfer of the gift to the British Museum (Natural 

 History), and he, therefore, with the consent of the meeting, handed 

 it over to Mr. G. J. Arrow for that purpose. — Mr. H. W. Andrews 

 exhibited a short series of Carphotricha guttularis, Mg., a scarce 

 Trypetid, taken at Milford Haven in July last, and a specimen of a 

 unicolorous form of Prosena syharita, F., from North Kent, July 

 30th, 1910. — Commander J. J. Walker exhibited specimens, commu- 

 nicated by Mr. J. N. Halbert, of Syagrius intrudens, Wat., an 

 Australian weevil, which had been introduced into a fernery at 

 Glasnevin, Co. Dublin, where it had done considerable damage ; also 

 of Conops signata, Wiedemann, male and female, a Dipteron new to 

 Britain, taken at Tubney, Berks, September 11th, 1910, and exhibited 

 on behalf of the captor, Mr. Joseph Collins, of the Oxford University 

 Museum.— Mr. E. C. Bedwell brought for exhibition examples of 

 Briichus pecUnicornis, L., a beetle usually looked upon as introduced 

 into tliis country in granaries, but in this case swept on an open 

 hiUside at Chipstead, Surrey ; also a variety of Badister bipusiidatm, 

 F., the usual black patches on the elytra being reduced to two small 

 black dots. — Mr. W. C. Crawley showed, with normal examples, a 

 brachypterous female of the ant Lasius Jiavus, found at Oddington, 

 near Oxford, in August, 1900, at which locality, about the same time, 

 were observed females of L. niger with short wings. Mr. H. St. J. 

 Donisthorpe remarked that Mrazek had recently shown that the 

 short wings of L. alienns were caused by the ant being infested by a 

 Nematode worm of the genus Mermis, and that Wheeler had found 

 this to be the case with short-winged females of L. neoniger in 

 America. He now exhibited a short- winged male of Technomyrmcx 

 albipes. Smith, together with an ordinary-wunged male which he had 

 recently taken at Kew, and suggested that the former might _ be 

 caused in the same way ; also ergatoid males of the same species, 

 taken at the same time, and two forms of Prenolcpis braueri, sub sp. 

 donisthorpei, Forel, taken at Kew; a black form, hermaphrodites and
