SOCIETIES. 



Entomological Society of London. — May 6th, 1903. — Professor 

 E. B. Poulton, M.A., D.Sc, F.R.S., President, in the chair. The 

 President exhibited one of the original invitations to join the Society 

 issued in 1834, and signed " G. R. Gray, Secretary pro. tern.'' Mr. 

 Willoughby Gai'dner exhibited nest-cells of Osmia xanthomelana from 

 Conway, North Wales. He said the species, one of our rarer mason 

 bees, places its beautifully constructed pitcher-shaped cells at the roots 

 of grass, usually four or five together. There is no previous record of 

 the nest having been found since Mr. Waterhouse discovered and 

 described it from Liverpool about sixty-five years ago. Mr. M. Jacoby 

 exhibited Arsoa lonfjhnana, Fairm., and A. aranea, from Madagascar, 

 the only other specimens of these species he knew of being in the 

 British Museum collection. He also exhibited Megcdo-pus melipona, 

 Bates, and M. pilipes from the Amazon, which bore a remarkable 

 resemblance to a bee. Mr. A. J. Chitty exhibited a water-beetle new 

 to Britain, viz. Hydropjorus bilineatus, Sturm., discovered by Mr. 

 Edward Waterhouse among some specimens of Hydroporus given by 

 Mr. Chitty to him as H. yrauularis. The specimens were taken at 

 Deal in 1891, and probably all records of granularis from Deal 

 relate to this species. He also exhibited a specimen of the rare Trechus 

 rivulans {incilis of Dawson), taken at Wicken Fen in August, 1900. 

 Mr. 0. E. Janson exhibited specimens of NeopJmdimus melnleucus, 

 Fairm., a goliath beetle from Upper Tonkin, and remarked that the 

 white colouring was derived from a dense clothing of peculiar semi- 

 transparent coarse scales which were apparently easily removed by 

 abrasion, and seemed to partake of the nature of the "fugitive" 

 scales found upon freshly-emerged specimens of Hemaris and other 

 Lepidoptera. The President read a communication from Mr. G. F. 

 Leigh, on " Protective Resemblance and other Modes of Defence 

 adopted by the Larvae and Pupag of Natal Lepidoptera," and exhibited 

 cocoons of Eublemmistis chlorozonea to illustrate some of his remarks. 

 He said that it was of great interest to hear the conclusions, as to the 

 general meaning of the colouring of Natal larvae, reached by one of 

 their Fellows who had so wide and intimate an experience as Mr. Leigh. 

 It was interesting to observe that Mr. Leigh considers the larva of 

 Papilio 7ureus to be conspicuous, when its pupa possesses a wonderful 

 power of colour adjustment, as was first shown and figured by Mrs. M. 

 E. Barker in the Transactions (1874, p. 519). The first account of 

 the larvae and pupae of Papilio dardanns was given by Mr. Mansel 

 Weale (Trans. Ent. Soc. Lond. 1874, p. 131). The combination of 

 many larvae to produce a patch of colour like the bark on which they
