MODERN WORK ON BRITISH ENTOMOLOGY. 



Our entomological magazines are largely filled with repetitions of already 

 well-known facts made by lepidopterists who still appear to consider that books 

 published almost, or quite, half a century ago, contain all the up-to-date infor- 

 mation obtainable on the subjects they discuss. For advanced work of the 

 most recent kind, the more scientific and educated lepidopterist should use the 

 following work as his text-book. 



The Natural History of the British 

 Lepidoptera, 



By J. W. TUTT, F.E.S., 



Vols. I, II, III. 



DeniySvc, strongly bound in cloth. Vol. I consisting of -560 pp.. Vol. II, of 584 pp., 



Vol. Ill, of 558 pp. 



Price £1 each Volume (net), Vols. I-IY, £3 7s. 6d. 



This work is the most important that has ever been offered to working and 

 scientific lepidopterists. It contains series of exhaustive monographs which no 

 entomologist should be without, and if he be dealing with the same super- 

 families, he will find in these volumes a mass of detailed information such as 

 never has been got together before on all the branches relating to the species 

 treated. At the same time, the discussion of general biological problems, and 

 the great amount of detail relating to such problems, give the books a value for 

 a class of workers quite apart from the British and Continental lepidopterists for 

 whom they were primarily intended. 



Vol. IV ^shortly to be published). 



Almost ready for publication. The price to Subscribers is 15s. 

 (22s. 6d. after publication). 



This volume will contain, besides its own detailed index, a compreheusive 

 General Index of Vols. I, II, III and IV, which is being prepared by Mr. G. 

 Wheeler, M.A., who has kindly volunteered to do the work. The present publishers 

 state that, having agreed to give booksellers more liberal terms than hitherto on 

 net books, the price per volume will have to be raised (22s. 6d. per volume has 

 been suggested). New subscribers are, therefore, urged to subscribe direct to 

 Mr. H. E. Page, " Bertrose," Gellatly Road, Hatcham, S.E., before publication. 

 Until the date of publication. Subscriptions for Vols. I, II, III and IV will be 

 accepted (if sent direct) at £3 7s. 6d., i.e., a discount of ^1 2s. 6d. on the lowest 

 price at which the volumes will be obtainable after the publication of Vol. IV. 



Rambles in Alpine Valleys. 



Bound in Cloth, with Map and Photographs of District. 



This book contains a series of essays dealing with the colours of insects, and sugges- 

 tions as to the relation in past time between the Alpine and British fauna. Many new 

 facts are brought forward, and entomological problems discussed from various standpoints. 



To be obtained from H. E. Paoe, "Bertrose," Gellatly Road, Hatcham.
