244 THE ENTOMOLOGIST. 



Tutt, J. W. Britisli Lepidoptera ; 9 vols. (1889-1914). Tutt's 

 " magnum ojyus." It is absolutely necessary to all students. 

 It was issued at £9, and is now to be purchased for about £4. 



Tutt, J. W. The British Noctuse and their Varieties ; 4 vols. 

 (1891-2). Published at £1 8s. ; now catalogued at £1 2s. to 

 £1 5s. 



Wheeler, The Rev. G. The Butterflies of Switzerland and the Alps 

 of Central Europe (1900). Admirable and indispensable to 

 all collectors and students of European Rhopalocera. Pub- 

 lished at 5s. per copy, or 6s. interleaved. Still to be obtained,. 

 I believe, from the author. 



Wilkinson, S. J. British Tortrices ; 1 vol. ; 4 uncoloured plates ; 

 published at 18s., priced now at 15s. My copy, purchased in 

 1917, cost 7s. 6d. The price has appreciated of late years. 



Wilkes, B. English Moths and Butterflies ; 120 coloured plates 

 (1747-60) ; published at £9 9s. Several subsequent and 

 inferior editions. The present cost of the original edition is 

 £3 to £4 according to condition and binding. 



Wood, W. Index Entomologicus (1839) ; 54 coloured plates 

 (1944 figures). An extremely useful work from several points 

 of view, but especially because Wood figured Stephens's types 

 of species and forms named by the latter. A copy is priced 

 at 45s. The Westwood edition (1854) has much inferior plates, 

 but it contains a useful supplement. It is valued at the same 

 price as the original edition. There is another inferior edition 

 dated 1845, which is priced at 30s. 



Zoologist, The. This magazine, between the years 1841-63, contained 

 a large amount of entomological matter. A year or two ago 

 I saw, too late, a copy of these volumes priced at Is. per 

 volume. This is the only occasion that I have noticed them 

 catalogued. 



Zoological Record (1864-1920) ; 57 vols. Published annually by 

 the Zoological Society. Gives references of everything of any 

 importance that is written within the year in every department 

 of zoology. This work is, of course, essential to every advanced 

 student. Unfortunately its bulk i prevents most private 

 libraries affording it shelf room. It is published at 30s. per 

 volume, and is usually catalogued second-hand at from 6s. 

 to 10s. per volume.
