Keep your knowledge of British Butterflies up to date. 



"Acquaintance with the author's other volumes on British Lepidoptera had prepared us for 

 masterly and exhaustive treatment of the Butterflies, and we certainly are not disappointed . . . 

 The book will be found exceedingly useful to everyone interested in British butterflies, but to the 

 student in the higher branches of entomology it will be indispensable." — The Entomologist, December, 

 1905.

 and March 15th. Price Is. net (post free Is. Id.) each part. 



The book is divisible into two parts — -(1) Chapters on the general subject, 

 (2) Systematic and Biological considerations of each family, subfamily, tribe, 

 genus and species. 



Parts I, II and III contain, in the first section, chapters entitled " General 

 observations on Butterflies," "Egglaying of Butterflies," "Eggs of Butterflies," 

 " Photographing Butterflies' Eggs," and " Obtaining Eggs of Butterflies." The 

 second section contains a detailed consideration of the superfamily Urbicolides 

 (Hesperiides) or skippers, the family Urbicolid^, the subfamily Thymelicin^, 

 the tribe Thymelicidi, the genus Adop^a, the species AcoPiEA lineola, and 

 A. FLAVA (thaumas), the genus Thymelicus acteon, the tribe Urbicolidi, the 

 genus AuGiADEs, and the species Augiades sylvanus. The species are described 

 under the headings of " Synonymy," "Original Description," "Imago," " Sexual 

 Dimorphism," " Gynandromorphism," "Comparison of allied species," "Varia- 

 tion," " Egglaying," " Ovum," " Comparison of eggs of allied species," "Habits 

 of Larva," "Ontogeny of Larva," "Larva," "Variation of Larva," "Food- 

 plants," " Puparium," " Pupa," " Time of Appearance " (with lists of actual dates 

 in given places), "Habitats," "Habits," "British Localities " and "Distribu- 

 tion." Plates illustrating the eggs of the Urbicolids, Chrysophanids, etc., are 

 published with these parts. 



Part IV contains, in addition, the conclusion of the chapter " Obtaining 

 Eggs of Butterflies " and part of another, " Butterfly Larvae and their Moult- 

 ings." It also contains the completion of the study of Augiades sylvanus, the 

 genus Urbicola, and the first part of a comprehensive study of the species 

 Urbicola comma, considered under the following headings : " Synonymy," 

 "Original Description," "Imago," "Sexual Dimorphism," "Genital Organs," 

 "Variation (including a summary of the forms occurring in the Palsearctic 

 area)," a critical review of the " European" forms, the " Eastern " forms, and 

 the " Southern " forms, etc. A plate illustrating the eggs of Thestorids and 

 LycEenids with this number. Parts V and VI conclude the study of Urbicola 



COMMA AND CyCLOPIDES PAL^MON. 



Every entomologist should send for Parts I, II, III, IV, V and VI (Is. Id. each, 

 post free) in order to judge the proposed scope and standard of the work. To make 

 it a real success every entomologist interested in our Butterflies should subscribe. 



It will also be considered an act of great kindness if every entomologist will 

 send information of any British species of which he has special knowledge. 



Every effort will be made to make the book worthy of the best traditions of 

 British entomology and British entomologists. 



Please enter my name as a subscriber for copies to the forthcoming 



work, A Natural History of the British Butterflies, for the first 20 parts of 

 which I forward the sum 17s. 6d. as set forth above.
