COLLECTION OF BRITISH MACRO- 

 LEPIDOPTERA. 



MR. J. C. STEVENS will 



SELL by AUCTION 



At his ROOMS, 38, York Street, Covent Garden, W.C. 



Towards the end of FEBRUARY or early in MARCH, 



The valuable and extensive COLLECTION of BRITISH 

 MACRO-LEPIDOPTERA, 



Formed by F. C. WOODFORDE, Esq., F.E.S., of Market Drayton. 

 The British Noctuae and their Yarieties. 



(Complete in 4 volumes. Price 7/- per vol.). 



(The price is being raised by ttie publishers to 301- 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 descriptions (or descrip- 

 tions 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 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 causes " — 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," 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 Noctuae," with a comparison 

 of the Nearctic and Palaearctic Noctuides. 



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

 und 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 information on this 

 s;roup, 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 

 I )und in any other published work.
