Deal.s 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," " hei'edity," "disease," "temperature," &c., in 

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

 Entomological Society of London, says, "An esj^eeially 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.' "
