268 THE ENTOMOLOGIST. 



I have never known anyone who cared to put a value on this 

 book, but a bookseller would possibly ask anything over £30 

 upon it. 



Hiibner, J. Verzeichniss bekannter Schmetterlinge ; Augsburg r 

 1816-26. This volume of 431 pages marks an era in the 

 literature, for it represents the genesis of the genera of the 

 order, as well as Hubner's final views on many of his names. 

 It is, of course, absolutely essential to every student. It seems 

 scarce, being seldom catalogued, but in 1912 it was priced in 

 a German catalogue at 4s. 6d. and in 1919 I obtained a copy 

 from Germany at about the same figure. 



Kennel, J. von. Die Palsearktischen Tortriciclen ; 727 pages of letter- 

 press and 24 large coloured plates (each of which contains about 

 100 figures) ; 1908-21. The latest work on the Tortricidse. 

 The plates are excellent, but the nomenclature of the forms 

 figured is extremely incorrect in many cases. The letterpress 

 is very useful as it brings what is known of the life-histories 

 up to date. The price at the present moment I am quoted 

 is £6. 



Ochsenheimer, F., und Treitschke, R Die Schmetterlinge von 

 Europa : 10 vols. ; Leipzig, 1807-1834. The first four volumes 

 were written by Ochsenheimer, the last six by Treitschke. 

 The value of this book is about 15s. It is, of course, valued for 

 the number of type species it describes. 



Poda, N. Insecta Musei Grsecensis ; Widmansbad, 1761. A little 

 volume containing a number of original descriptions. It is 

 extremely rare. There are, I believe, only two or three copies 

 in Britain, one of which is in the Library of the Entomological 

 Society. It would be extremely difficult to put a value on 

 this little book, but if a bookseller who knew his business 

 had one he would probably ask £40 or £50, or more, for it, 

 although a well-known firm sold one not so many years ago 

 for five shillings ! 



Eebel, H. Studien fiber die Lepidopterenfauna der Balklander ;. 

 3 Tiel ; 3 coloured plates ; Vienna, 1903-1913. A very useful 

 fauna list of certain parts of the Balkans. The plates are 

 extremely good. To be obtained for about 30s. 



Eosel von Bosenhof, A. J. Insecten-Belustigungen ; 4 vols. ; 

 with Kleeman's Beitrage, 2 vols., 6 vols, in all ; 404 coloured 

 plates; Nuremberg, 1746-93. Eosel was a miniature painter,, 

 and his work contains some of the most beautiful figures that 

 have ever been produced. Apart from this much of its value 

 results from subsequent authors in describing a species 

 identifying it with Eosel's figures. There were several editions 

 of variable value, and copies with the total number of plates 

 are rare. The original and best edition is extremelv scarce. I
