The Natural History of the British Lepidoptera. 



(A Text-book for Students and Collectors.) 



Vols. I, II, aud III. (Price 20s. each volume net. 54s. for the 3 vols.) 

 This work is the most advanced scientific text-book ever issued on the British Lepi- 

 doptera. Besides cliapters on the general subject, each volume contains, in the systematic 

 part, a detailed account of the species, each of which is treated under a variety of headings^ 

 «.<■/., Synonymy, Original description. Imago, Sexual Dimorphism, Gynandromorphism, 

 Variation, Egg-laying, Ovum, Habits of Larva, Larva, Variation of Larva, Pupation, 

 Cocoon, Pupa, Pupal Habits, Dehiscence, Variation of duration of pupal stage, Food- 

 plants, Parasites, Habits, Habitat, Time of appearance. Localities, Distribution. The 

 entomologist htis, here, a revision of the superfamilies treated in a modern scientific 

 manner, and the work is of first importance to workers at these groups in all parts of the 

 world. The systematic part deals particularly with the species found in Britain, and 

 affords such a mass of detail concerning the Biitish species as has never before been 

 brought together. To the general biologist the discussion and details relating to the 

 hybridism, gynandromorphisni, variation and life-histories of the species dealt with, afford 

 a mass of material not to be obtained elsewhere ; whilst to the lepidopterist pure and 

 simple, the mass of information will enable him to study his subject from many different 

 standpoints ; to the collector the information concerning the habits, foodplants, habitat, 

 and localities, is as full as it can possibly be in the present state of our knowledge ; whilst 

 it would take the phenologist and student of distribution years to collect anything like the 

 number of facts bearing on their own special work that is here ready for their digestion. 

 Each volume contains a great deal of original matter, not only from the observations of 

 the author, but also from Dr. T. A. Chapman, Messrs. A. W. Bacot and L. B. Prout, who 

 have collaborated with the author in their own branches of study for the work. Besides 

 these, some 200 other lepidopterists have helped in different ways and in various degrees. 

 The volumes contain a vast amount of absolutely new material relating to all the species 

 treated, and, at the same time, the whole of the information to be obtained from tbe long 

 series of volumes of Hie EntomologinV a Monthly Magazine, The Entomologist, Tlte Ento- 

 iiiologixt'x Record, The Entoviologisfx Weekly Intelligencer, The Zoologist, The Trannuctions 

 of the Entomological Society of London, as well as that contained in the works of Stainton, 

 Newnian, Meyrick, Barrett, and others — also in the leading Continental Transactions and 

 Magazines — has been carefully summarised and noted. The works of all the leading 

 Continental authorities have also been carefully overhauled, and the important facts 

 gleaned therefrom. So much labour has been expended in making the volume worthy of 

 acceptance to all lepidopterists, and the cost of production of so large a book is so heavy, 

 that the support of every lepidopterist is earnestly solicited. To those lepidopterists who 

 have become interested in the scientific study of the subject they profess, these volumes 

 will open up a new world. The amount of labour expended in producing them has been 

 enormous, and, expensive as the works may appear, are really cheaper than any other 

 published work on the subject, for they represent a whole library of information that is 

 otherwise practically unolitainable. 



Practical Hints for the Field Lepidopterist. 



Parts I and II. 

 Price 6s. each net. Sold separately. (Interleaved for Collector's own notes.) 



This is one of the most useful, as it has certainly proved one of the most popular, 

 books ever offered to the field-lepidopterist, and will save him immense time, trouble, and 

 expense in prosecuting his woi'k. In each part there are some one thoustmd tuo lumdred 

 and fifty different practical hints included, telling the lepidopterist how, when, and where 

 to work for the more desirable species. The book is crammed full of information, and no 

 lepidopterist can afford to be without a copy of it. The older collectors will not only find 

 many hints that they do not know, but will find many facts that they may wish to 

 lemember presented in a compact form. To the younger collector it offers a mass of 

 information that he could not hope to accumulate by himself in very many years of field- 

 work. To all it must remain one of the most necessary books ever published for the use 

 of field lepidopterists. The contents are divided into the following chapters. (1) January, 

 February, and early March ; (2) Late March and April; (3) May ; (4) June ; (5) July ; 

 (0) August; (7) September; (8) October; (9) November and December. Each chapter 

 opens with a general review of the field work that can be done in the period indicated, 

 and this is followed by a classified list of the "Hints" available for the period. Now 

 that the whole of the material is grouped, it offers a great mass of exact, useful and
