given in Mr. Austen's paper, except tlmt L. xylvatica is only mentioned by him as 

 from Devon ; the dates indicate that it is probably earlier in appearance than the 

 other species. — W. Abmston Vice, 19, Belvoir Street, Leicester : March 2'dth, 1900. 



British localities for Hydrilla palustris. — Mr. F. H. Day, referring {ante p. 89) 

 to the capture of Hydrilla palustris near Carlisle, says that the species " does not 

 occur elsewhere away from the Fens." He may, therefore, be as glad to be reminded 

 as I was myself, when talking to Mr. L. B. Prout a few days ago, that a specimen of 

 n. palustris is recorded in Stainton's Manual, vol. i, p. 216, as having been taken 

 near York, which is far removed from the district known as " the Fens." I am not 

 aware that the insect has been met with near York of recent years, but this is pro- 

 bably due to its not having been persistently worked for in the right way and at the 

 right time, and it would be rash to assert that it no longer occurs there. — Eustace 

 E. Bankes, Norden, Corfe Castle : April 9th, 1900. 



Entomological Society of London : March 21st, 1900. — Mr. C. O. 

 Waterhouse, Vice-President, in the Chair. 



Mr. R. T. Cassal, of A8hby,near Doncaster; Mr. Neville Chamberlain, of High- 

 bury, Moor Green, near Birmingham ; Mr. E. A. Elliott, of 41, Holland Park, W. ; 

 Mr. H. Willoughby Ellis, of Knowle, Warwickshire ; Mr. J. H. Keys, of 6, Seymour 

 Terrace, Lipson, Plymouth ; the Rev. W. J. Leigh Phillips, M.A., of The Cottage, 

 Parkwood Road, Tavistock, Devon ; Mr. H. W. Shepheard-Walwyn, M.A., of 

 Glensyde, Bidborough, near Tunbridge Wells ; and Mr. C. J. Watkins, of King's 

 Mill House, Painswiek, Gloucestershire ; were elected Fellows of the Society. 



Mr. R. McLachlan exhibited an extraordinary aberration of Enallagma cya- 

 thigerum, Charp., taken by Mr. Morton at Glen Lochay, Scotland : the remarkable 

 feature consisted in the predominance of black over blue in the colouration of the 

 abdomen. Mr. M. Burr, a macropterous var. of Xiphidium dorsale, Latr., captured 

 by Mr. Harwood near Clacton, remarking that the fact of this species presenting a 

 macropterous form was apparently unrecorded hitherto. Mr. W. J. Kaye, Nyssia 

 hispidaria, an asymmetrical specimen taken on Wimbledon Common, the left fore- 

 wing of which was perfectly developed but extremely small, and the left hind-wing 

 slightly more elongated than the right hind-wing. Mr. C. O. Waterhouse, a tube 

 which formed the entrance to a nest of a Trigorta, sent from Singapore by Mr H. 

 N. Ridley ; it was about fifteen inches in length, of a resinous substance, but more 

 waxy toward the end, which was spoon-shaped ; also a portion of the resinous mass 

 formed within the trees by these bees, and stated that one of these masses sent from 

 Penang by Mr. Ridley weighed 15 lbs. The true nest of the Trigona consists of an 

 irregular mass of cells filled with honey, quite distinct from the resinous formation. 

 A paper was communicated by Mr. W. H. Ashmead, Assistant-Curator of the U. 

 S. Nat. Hist. Museum, on " The Aculeate Hymenoptera of the Islands of St. Vincent 

 and Grenada, with additions to the Parasitic Hymenoptera, and a List of the 

 described Hymenoptera of the West Indies." — C. J. Gahan and H. RoWLAND- 

 BiiowN, Hon. Sees.
