British Butterflies. 



(Illustrated. Crown 8vo., Cloth, Gilt. Price 5/-). 



This book consists of 476 pages, contains 10 full-page illustrations, and 45 wood- 

 cuts. There are figures of every British butterfly. Sometimes three or four figures of 

 the same butterfly to illustrate the two sexes, underside and variation are given. The 

 full-page illustrations and most of the wood-cuts have been drawn by the well-known 

 entomological artist, Mr. W. A. Pearce. 



Each British butterfly is described under the following heads: — (1) Synonymy. 

 (2) Imago. (3) Variations, with summarised diagnoses of all described forms, British 

 and Continental. (4) Egg. (5) Larva. (6) Pupa. (7) Time of appearance. (8) 

 Habitat and Distribution. Besides these, there are extended remarks on each of the 

 Tribes, Subfamilies, Families, Divisions and Superfamilies. The descriptions of the 

 " Larvae" and "Pupae" are mostly original. There are 282 aberrations and varieties 

 diagnosed, of which in are described for the first time. The varieties and aberrations 

 found in every part of the world are dealt with. 



At the end of each chapter is a brief summary giving the following information, in 

 tabular form, for each species : — I. Date for finding (1) the ovum, (2) the larva, (3) 

 the pupa, (4) the imago. II. The Method of Pupation. III. Food-plants. 



The preliminary chapters consist of a series on the structure of the Egg, Larva, 

 Pupa, .&c. ; also others on practical work — Collecting, Pinning, Setting, Storing, 

 Labelling, &c. 



Practical Hints for the Field Lepidopterist. 



Complete in two parts. Price 12/- (6/- each part) net. 



(INTERLEAVED FOR THE COLLECTOR'S OWN NOTES). 



This is one of the most useful, accurate, and important books ever offered to the 

 field -lepidopterist, and will save him time, trouble and expense in prosecuting his 

 work. In each part are some one thousand two hundred and fifty practical hints, 

 telling the lepidopterist, how, when and where to work for the most desirable species. 

 No lepidopterist can afford to be without a copy of this book. 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; (6) August; (7) September ; (8) 

 October; (9) November and December. Each chapter of Part I 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. In Part II each 

 chapter also contains a preliminary summary of the work to be done during each 

 month, but, as the method of work in the field was more particularly dealt with in 

 Part I, these summaries in Part II deal more especially with the points raised by the 

 various methods of Rearing larvae in confinement, Sleeving, Breeding-cages, Food, 

 and Feeding larvae ; Obtaining eggs in confinement from butterflies and moths ; 

 Special treatment of pupae ; Keeping pupae through winter ; Special treatment of 

 certain larvae in order to obtain pupae ; Sugaring ; Assembling ; Forcing, and a host 

 of similar important topics to the entomologist. Quite new ground is broken and 

 there is no repetition. The whole of the material thus grouped offers a great mass of 

 exact, useful and reliable information, bearing on the work of the lepidopterist in the 

 field, telling him exactly what to do and how to do it in the fewest possible words and 

 in the least possible space. Such information could only be gathered by the 

 individual worker as the result of many years' observation and by reference to many 

 books in which the facts are buried amongst a mass of other entomological detail. 

 Lepidopterists, experienced and inexperienced, will find in this book much infor- 

 mation that will suggest quite new lines of work in their collecting, and enable 

 them to find, in close proximity to their homes, species which they had never 

 suspected to be in their vicinity, and the saving of time and trouble will thus be 

 enormous. 



The book has been interleaved, so that collectors can add therein their own 

 notes, dates, &c. Reference has been made easy, the notes for each month being 

 classed under the superfamily heads to which they belong, e.g., those for June come 

 under — Tineina (unclassified), Tineides, Adelides, Plutellides, Elachistides, 

 Gracillariides, Argyresthiides, Coleophorides, Lithocolletides, Nepticulides, Tort- 

 ricides, Pyraloides, Crambides, Pvralidee, Drepanulides, Cymatophorides, Brephides, 

 Geometrides, Pterophoiides, Sesiides, Zeuzerides. Cochlidides, Psychides, Anthro- 

 cerides, Lachneides, Sphin^ides, Deltoides, Lymantriides, Nycteolides, Notodontides, 

 Noctuides, Arctiides and Papilionides. These also will give an idea of the range 

 covered by the notes.
