Melanism and Melanochroism in Lepidoptera, 



By J. W, TUTT, F.E.S. 



Bound in cloth, price 2s. 6d. 



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

 the different forms of Melanism and Melanochroism: summarises the references scat- 

 tered over the Entomolo2;ical Magazines for the last 3t» years, and thus saves students 

 the expense of investing in the old Vols, of expensive magazines; contains full data re- 

 specting the distribution of melanic forms in Britain, and theories to account for theii 

 origin; the special value of " natural selection," "environment," "heredity," "disease,'* 

 " temperature," &c. in particular cases. Lord Walsingham, in his Presidential address 

 to the Fellows of the Entomological Society of London, says: — "An especiHll) • 

 interesting line of enquiry as connected with the use and value of colour in insects, ii j 

 that which has been followed up in Mr. Tutt's series of papers on ' Melanism ant 

 Melanochroism.' "
