THE ENTOMOLOGIST S RECORD. 



on about the same level. Under the fourth heading, the paper dealt 

 with the advantage of mimicry and protective coloration to the indi- 

 vidual insect, from the personal observation of the author. 



We have received some interesting papers, entitled " Contributions 

 to the theory of warning colours and mimicry," by Mr. Frank Finn, 

 B.A., F.Z.S. In these the author gives detailed results of experiments, 

 made by himself, with Indian birds and lizards on supposed " pro- 

 tected " and " non-protected" species of insects. 



The third Annual Congress of the South-eastern Union of Scien- 

 tific Societies was held on June 2nd, 3rd and 4th, at the Town Hall, 

 Croydon. The Congress proved most successful, and has evidently 

 come to stay. Based on the lines of the British Association meetings, 

 the leading scientific men of the neighbourhood in which the Congress 

 is held offer hospitality to the delegates, and hence many acquaintances 

 between well-known scientific men and those of the district are made. 

 On Thursday evening the Presidential address, by Professor G. S. 

 Boulger, F.L.S., F.G.S., was delivered. Friday morning and after- 

 noon were devoted to the reading of scientific papers, of which one 

 only was distinctly entomological, " The scientific aspects of Ento- 

 mology," by J. W. Tutt. On Friday evening, a public reception by 

 the Mayor and Corporation took place at the Town Hall, which was 

 tastefully decorated, and certain rooms devoted to the exhibition of 

 natural laistory specimens (one by Mr. P. Crowley, F.Z.S., F.E.S., was 

 occupied with magnificent exotic lepidoptera). After the reception Mr. 

 Enock gave his excellent illustrated lecture, " The tiger-beetle," with 

 his usual success. Saturday morning was devoted to papers, and in the 

 afternoon two out-door excursions were arranged, one to Beddington, 

 the other to Addington. Mr. P. Crowley's house was the centre of the 

 entomological section socially, and the members of that section desire to 

 express to him their hearty thanks. Among the entomologists present 

 were Dr. T. A. Chapman, Mr. F. Enock, Mr. R. Adkin, Mr. H. St. John 

 K. Donisthorpe, Mr. Stanley Edwards, Mr. J. A. Clark, Mr. L. B. 

 Prout, Mr. L. J. Tremayne, Mr. J. W. Tutt. The Congress 

 next year is to be held at Rochester, when the ancient city will 

 no doubt seek to establish a record, for the Rochester Naturalist's 

 Club is not only an exceedingly flourishing institution, but it 

 includes in its membership many of the leading citizens. Still 

 it has much to do to beat Croydon, although we doubt not the 

 grand old city will attempt to do so. The Congress for 1900 will 

 probably be held at Brighton, as the delegates from the " queen " 

 of the south coast also brought an invitation for next year. Member- 

 ship (to non-members of the afiiliated societies) is only 5/-. Particulars 

 from Dr. Abbott, 83, Upper Grosvenor Road, Tunbridge Wells. 



Mr, L. Upcott Gill, Strand, W.C, is bringing out, by subscription 

 (price 10s. 6d.), a work on " British Dragonflies," by W. J. Lucas, B.A. 

 The work will be a complete and up-to-date handbook, illustrated 

 (eggs, nymphs, and structural details) in Mr. Lucas' own inimitable 

 way, and will consist of 8 separate chapters, besides a full seriatim 

 account (and coloured illustration) of each British species belonging to 

 the Odonata. On publication, the price of the book will be raised to 

 15s., and after publication will be again raised to 21s. net. What Mr. 

 Lucas writes on British Odonata ought to be read by everyone interested 

 in the order. We wish the work every success.
