The most important work ever ol'fered to lepidopterists. The British fauna is 

 merely taken as the groundwork for the thorough revision of each superfamily treated, 

 and the work thus becomes of first importance to all lepidopterists in the world — 

 systematists, biologists, synonymists, phenologists, &c. This important work puts all 

 others of the kind into the shade. It deserves our full attention and recognition, and the 

 opportunity for its study is not to be missed by any students of European lepidoptera to 

 whom it is no less valualjle than the Briton (licii. Kiit. Zcitif., December 1902).

(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," itc, in 

 particular case-. 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.' "
