(A textbook for Students and Collectors.)

This is one of the most important works ever offered to lepidopterists. The British 

 fauna is merely taken as a 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 valuable than the Briton " 

 (Berl. Ent. Zeitschrift, Dec. 1902). 



The British Noctuse and their Varieties. 



Complete in 4 volumes. 28/- per set, net. Demy 8vo., strongly bound in Cloth. 



The four volumes comprise the most complete textbook ever issued on the 

 Noctuides. The work contains critical notes on the synonymy, and gives the original 

 type "description (or description of the original figure) of every British species, the 

 type description of every known variety (European, African, Asiatic, or American) 

 of these 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 development 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 cause " — with a detailed account of the action of natural selection in 

 producing melanism, albinism, &c. 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," explain- 

 ing, 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 lepidop- 

 terists, and up to the present time some 500 complete sets of the work have been 

 sold. The treatise is invaluable to all working collectors who want the latest infor- 

 mation 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. 



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 distri- 

 bution ofmelanic forms in Britain, and theories to account for their 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 especially interesting line of 

 enquiry as connected 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."
