Practical Hints-: Field Lepidopterist 



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



Parts I and II, Price 6s. each. 



(Interleaved for collector's own notes), 



should do so without delay. Some '2500 hints culled from all the best field- 

 workers will tell collectors how to get almost all their desiderata themselves. 

 Dozens of lepidopterists have written to the author stating that by means of 

 the hints contained in this work they have discovered many species of rare 

 lepidoptera in their own collecting-grounds, which were quite unsuspected in 

 the neighbourhood before. 



With the publication of Part III, the few copies of Part I that are now left 

 will only be obtainable at an increased price. 



It is further proposed to publish in the course of a few weeks 



A THIRD (and LAST) PART of 



Practical Hints for the Field Lepidopterist, 



WITH A DETAILED 



Specific Index to Parts I, 11 and HI 



(By H. J. TURNER, F.E.S.). 



This part is to be put in the printer's hands at once and will be probably 

 larger than either Part I or Part II, will be interleaved, will contain detailed 

 chapters on the Egg, Larval and Pupal stages, and modes of collecting, &c., in 

 these stages. Already considerably more than 1000 practical hints of the form 

 now so well known to our field-workers have been accumulated. Those who 

 think these books are reprints of the small section of hints that have appeared 

 in the Magazine should see the books to discover their mistake. It was because 

 there was no room in the Magazine for a tenth of the hints in hand that the 

 books were published. 



Dear Sir, — 



Please enter my name as a guarantor for copies of Practical Hints 



for the Field Lepidopterist, Part III, and the Index to Parts I, II, and III, for each 

 copy of which I will send the sum of 4s. 6d. on publication.

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."
