The Editor of The Entomologisfs Record writes: — "I know nothing in this particular 

 direction so well-suited for educational purposes as your excellently mounted ' Lifehistories 

 of Lepidoptera, Hymenoptera, &c.' One could wish that there were three or four typical 

 cases in every Primary and Secondary School in Europe. Certainly everyone engaged 

 in educational work, in the British Isles at least, would use these cases if they knew of 

 them." Send for List to —

The British Noctuae and their Varieties. 



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



The four volumes comprise the most complete text-book ever issued on the Noctciues. 

 It contains critical notes on the synonymy, the original type descriptions (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 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. HI 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 

 Nearctie and Palaearctic Noctuides. 



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

 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 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.
