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."— T/tf Entomologist , December,
