A Natural History of the British Lepidoptera. 



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



Four volumes. Price £1 each volume, net. Vols. I-IV, £3 7s. 6d. Demy 8vo., thick, 



strongly bound in cloth. 

 Volume I contains 560 pp. + vi pp. Volume II, 584 pp. + viii pp. Volume III, 558 pp. 

 + xi pp. Volume IV, 535 pp. + xvii pp. 

 The most important work ever offered to lepidopterists. The British fauna is 

 merely taken as the 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, phenologisbs, &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. Zeits., December 1902).

(Demy 8vo., 161 pp., bound in Cloth.)

 This book contains an introductory chapter on " Collecting," " Killing " and

 of larva, of pupa, and of imago, food-plants, mode of pupation, and a complete account (so 

 far as is known) of every British species, under the headings of " Synonymy," " Imago," 

 "Variation," "Ovum," "Larva," "Food-plants," " Pupa," " Habitat," and "Distribu- 

 tion." It is much the most complete and trustworthy account of this interesting group of 

 Lepidoptera that has ever been published.

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 valueo f 

 "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 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.' "
