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," &e., in 

 particular eases. 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.' " 



The British Noctuae and their Varieties. 



(Complete in 4 volumes. Price 7s. per vol., 28s. per set). 



These four volumes comprise the most complete text-book ever issued on the 

 NocTuiDES. The work contains critical notes on the synonymy, the original type descrip- 

 tions (or descriptions of the original figures) of every British species, the type descriptions 

 of all known varieties of each British species, tabulated diagnoses and short descriptions 

 of the various phases of variation of the more polymorphic species ; all the data known 

 concerning the rare and reputed British species. Complete notes on the lines of develop- 

 ment of the general variation observed in the various families and genera. The 

 geographical range of the various species and their varieties, as well as special notes by 

 lepidopterists who have paid particular attention to certain species. 



Each volume has an extended introduction. That to Vol. I deals with "General 

 variation and its causes" — with a detailed account of the action of natural selection in 

 producing melanism, albinism, etc. That to Vol. II deals with "The evolution and 

 genetic sequence of insect colours," the most complete review of the subject published. 

 That to Vol. Ill deals with " Secondary Sexual Characters in Lepidoptera," explaining 

 so far as is known, a consideration of the organs (and their functions) included in the 

 term. That to Vol. IV deals with " The classification of the Noctuse," with a comparison 

 of the Nearctic and Palaearctic Noctuides. 



The first subscription list comprised some 200 of our leading British lepidopterists, 

 and up to the present time some 550 complete sets of the work have been sold. 

 The treatise is invaluable to all working collectors who want the latest information on this 

 group, and contains large quantities of material collected from foreign magazines and the 

 works of old British authors, arranged in connection with each species, and not to be 

 found in any other published work. 



To be obtained from J. Herbert Tutt, 119, Westcombe Hill, Blackheath, S.E.
