burg Dec. 22, 1823, and advertises for sale such of Hiibner's works as 

 had appeared up to that time, and states of the Sammlung, that there 

 were the title page, twenty-five pages of descriptive matter and six hund- 

 red and sixty-three plates, namely: Papilio 161; Sphinx 34; Bombyx 

 67; Noctua 151; Geometra 100; Pyralis 30; Tortrix 46; Tinea 67; Al- 

 ucita 7. This is signed by Hiibner himself. 



The first part of Geyer's contribution is still in the original wrappers 

 dated Augsburg 1830, and contains the Tortricids, plates 48 to 52 inclu- 

 sive, with title, preface and two sheets of text. The second part of the 

 continuation is in the original wrappers dated Augsburg 1834, and con- 

 tains five plates of the Noctuids, Nos. 158 to 162. In the same wrap- 

 pers is contained a prospectus of the whole work dated Augsburg, Jan. 1, 

 1834, giving the prices and signed by Carl Geyer. In this are adver- 

 tised, fifty-three plates of the Tortricids, all that were ever published, with 

 the number of plates of the other families. 



A careful examination of the contemporaneous works is of import- 

 ance in this question and I have looked over all that I have access to 

 In Illiger's edition of the Verzeichniss der Wiener Gegend which bears 

 the date of 1801, there is a notice in the first volume as follows:-"The 

 2nd volume (that containing the Tortricids) is already in press. Ostern, 

 1800." Now this second volume contains reference to the first thirty 

 plates of Hiibner's Tortricids and as it was already in press in 1800, these 

 plates must have been issued before 1800, but from the first prospectus 

 mentioned above, they must have been issued later than 1796. 



The portion of Haworth's Lepidoptera Britanica which includes the 

 Tortricids, — as shown by the original wrappers in the Banksian Library 

 in London, — was published in 181 1 and contains references only to the 

 first thirty plates of the Tortricids in the Sammlung. Whether there 

 were any more published at that time I have no means now of determin- 

 ing but of course Haworth had seen no more. 



Charpentier and Sommer's Ziinsler, Wickler etc. published in 182 1, 

 contains references to plate 40, so that this plate must have been in their 

 hands at that time and the first 40 plates must have been published be- 

 fore 1821. On the 22d of December 1823, Hiibner advertises the first 

 46 plates of his Tortricids for sale as shown above by the fifth prospectus. 

 We may reasonably infer that this last date is the time of publication of 

 plates 41 to 46 inclusive. 



Hiibner's Verzeichniss contains references to the plates of the Tor- 

 tricids up to and including plate 46, and yet this work purports to 

 have been published in 1816. We see no way to explain this discrep- 

 ancy except to agree with Scudder that the Verzeichniss was published in 

 parts and that only the first part with the title page really appeared in
