Melanism and Melanochroism in British Lepidoptera. 



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



Bound in Cloth, Price 2/6. 



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. Tdtt's series of papers on ' Melanism and Melanochroism.' "

This book consists of 476 pages, contains 10 full-page illustrations, and 45 wood-cuts. 

 There are figures of every British butterfly. Sometimes three or four figures of the same

 artist, Mr. W. A. Pearce.

 Imago, (3) Variation, with summarised diagnoses of all described forms, British and Con-

 Besides these, there are extended remarks on each of the Tribes, Sub-families, Families, 

 Divisions, and Superfamilies. The descriptions of the " Larvae " and " Pupae " are mostly 

 original. There are 282 aberrations and varieties diagnosed, of which 111 are described 

 for the first time. 



At the end of each chapter is a brief summary giving the following information, in 

 tabular form, for each species : — I. Dates for finding (1) the ovum, (2) the larva, (3) the 

 pupa (4) the imago. II. The Method of Pupation. III. Food-plants. 



The preliminary chapters consist of a series on the structure, &c., of the Egg, Larva,
