Melanism and Melanochroism in British Lepidoptera 



(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.' "
