A NATURAL HISTORY 



OF THE 



BRITISH BUTTERFLIES, 



THEIR WORLDWIDE VARIATION ^ND DISTRIBUTION. 

 Vol. IV. 



Commencing with the Variation and Life-histories of AyrUuU's ooridoji and Polijommatus 

 icarus (with four plates of the named aberrations and varieties of the first-named species 

 together with many photomicrographs of larval and pupal structure. Similar plates of 

 P. icarus are awaiting publication.) 



Probably the finest life-histories of any species of lepidoptera ever published. The next 

 species to be treated is Aricia astrarehe, a still more interesting one with regard to its 

 Varieties and Aberrations. 



Part XI. will shortly be issued. 

 Subscription for 20 parts 17s. 6d.

By GEO. WHEELER, MrA., F.E.S., F.Z.S. 



Price 5s. net. Interleaved, 6s. 



Limp cloth covers. — Handy for the knaiisack. 



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

 flies, 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 

 lepidopterists 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 We can cordially recommend it " — H. Eowland-

Melanism and Melanochroism in British Liepidoptera 



(Demy 8vo., bound in Cloth. Price 5/-.) 



Deals exhaustively with all the views brought forward by scientists to account for the 

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

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

 "natural selection," "environment," "heredity," "disease," "temperature," etc., in 

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

 Entomological Society of London, says, " An especially 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.' "
