SOCIETIES. 



Entomological Socikty of London. — November 18th, 1903. — Pro- 

 fessor E. B. Poulton, D.Sc, F.R.S., President, in the chair. — Mr. John 

 Rowland Cattle, of Nettleton Manor, Caistor and 59, Chancery Lane, 

 E.C., and Mr. E. J. Hare, of 8, HiUsboro' Road, East Dulwich, S.E., 

 were elected Fellows of the Society. — Mr. G. C. Champion exhibited 

 numerous specimens of both sexes of Xyleborus dispar, from Moncayo, 

 Spain, taken out of beech-stumps. — Mr. F. B. Jennings (1), on behalf 

 of Mr. H. Britten, of Great Salkeld, Cumberland, a specimen of Tro- 

 piphonis tomeiitosiis, Marsh, from Great Salkeld, showing the deciduous 

 false mandibles intact ; (2), a female specimen of Anchomenus parum- 

 pimctatus, F., from the same locality, showing a malformation of the 

 middle right tibia, which was abnormally thin, and bent in the centre, 

 but thickened at the base ; the right antenna also had the last seven 

 joints flattened and dilated. — Mr. Jennings also exhibited, on his own 

 behalf, Apion smujuineum, De G., taken at Brandon, Suffolk, in August 

 last, on Rumex. — Mr. H. St. J. K. Donisthorpe, Apium sorbi, male, 

 taken this year at Freshwater, Isle of Wight, and said that the male 

 of this species was extremely rare. — Mr. M, Burr, two females and two 

 males of the largest known earwig, Anisolabis colossea, Dohrn., from 

 New South Wales. — Mr. A. J. Chitty, a specmien of the rare Homa- 

 lium testaceum taken in Blean Wood in 1900, and a pair of bees, 

 Noiitada (juttulata, of which the male has never been recorded hitherto 

 in Britain, taken by him at Huntingfield, Kent, in May last. — Dr. 

 Norman Joy (1), Enconnus maklini, Mannerh., taken at Bradfield in 

 July, 1901, new to the British list of Coleoptera, and (2), a series of 

 beetles taken at Bradfield at the exuding sap of trees attacked by 

 Cossus lujniperda. — Colonel J. W. Yerbury, specimens of rare British 

 Diptera from Porthcawl, including Leptopa Jiliformis, Zett., Pelidno- 

 ptera nigripennis, Lucina fabciata, and T/iyreophora fuscata. Dr. T. A. 

 Chapman, specimens of Chrysophanus pJdccas from Reigate, Locarno, 

 and Spain, showing the apparent effects of temperature on the wing 

 markings and coloration. Mr. G. J. Arrow showed specimens and dia- 

 grams illustrating a remarkable kind of variability noticed in beetles of 

 the Trogid genus Acantkocerus. The President showed an exhibit sent by 

 Mr. A. H. Thayer, of Mondarock, N.H., U.S.A. The greyish sil- 

 houettes of two butterflies were represented in a tint nearly the same 

 as the basal ground, but sufficiently distinct to be easily recognisable. 

 Mr. Thayer considered the dark ground colour of many Rhopalocerous 

 insects represented shadow under vegetation, the white submarginal 

 lines and dots a generalization of flowers and flower-masses. But these 

 markings also had a second meaning in that they tended to obliterate the 

 tell-tale margin of the wings. Tlie President also exhibited specimens 

 of Drurya antimachus, together with the butterflies whicli he suggested 

 as forming a group synaposematic with it. The central species 

 appeared to be Acrcca egma, round which clustered a number of other 

 species of the same genus so much alike as to be probably indis- 

 tinguishable upon the wing. Examples of these were exhibited, viz. 

 A. zetis, jjerenna, royersi, and pharsalus. Another beautiful Papilionian 

 member of the group, P. ridleyanus, was also shown ; in pattern it was 

 nearest to that of the male A. egina. In fact, so close was the resem-
