This book is of the highest value not only to collectors of Continental Butter- 

 Hies, but to all those who collect British butterflies, as it gives a great many detailed 

 facts about the species in which they are more particularly interested. 



The details of Variation and Distribution are particularly important, and those 

 iepidopterists to whom Kane's book has long been a treasured friend, will find in this 

 more information, more detail, and many more localities than were at the disposal of 

 the author of the earlier volume. 



" To those who carry a net abroad, this handbook will be invaluable as a book of 



reference. . . . . \Ve can cordially recommend it " — H. Eowland-

Melanism and Melanochroism in British Lepidoptera. 



(Demy tivo., bound in Cloth. Price 5/-.) 



Deals e.xhaustively with all the views brought forward by scientists to account for the 

 forms of melanism and melanochroism ; contains full data rcvspecting the distribution of 

 raelanic forms in Britain, and theories to account for their origin ; the special value of 

 "natural selection,," "environment," "heredity," "disease," ' temperature," t&c, in 

 particular cases. Lord Walsingham, in his Presidential address to the Fellows of the 

 Entomological Society of London, says, "An esi)ecially interesting line of enquiry as con- 

 nected with the use and value of colour in insects is that which has been followed up in 

 Mr. Tutt's series of papers on ' Melanism and Melanochroism.' "
