"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 

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

 1905.
