The dates for Hiibner'a Zutrage, — 



1806 Herrich-Schaffer. 



1818 — 1837 Hagen. . 



Hiibner cites vol. i. of the " Sammlung," in his Verzeichniss ; and figs 83, 84, 

 of the " Zutrage." As the Zutrage and vol. ii. of the Ex. Schmett. are on a 

 different plan to vol. i, it seems that the former was commenced after the comple- 

 tion of vol. i. of the latter. Herrich-Schaffer' s date of 1806 is evidently too early 

 for the Zntr. ; and Hagen's (unless Hiibner cites unpublished plates) too late. 

 Vol. ii. of the Sammlung is evidently subsequent to 1816. 



Similar difficulties, but less serious, exist with respect to Esper, Cramer, and 

 some other works. Any information respecting the dates of these or similar works 

 would be most acceptable, as without more definite information than I possess at 

 present, I cannot fix the synonymy of species described or figured by these authors 

 with sufficient precision. — W. F. Kieby, Dublin, August 24<th. 



[In my copy of Hiibner's Sammlung Europaischer Schmetterlinge, which was 

 in the possession of the late James Francis Stephens from the year 1840 to his 

 death, are some valuable pencil notes as to the dates of Hiibner's Plates. 



My attention had been called to these more than once by Mr. Stephens in his 

 life-time, when we were discussing (as we frequently did) whether in this or that 

 case Hiibner or Haworth had priority. Naturally, I have only concerned myself 

 with these pencil notes in the 5th volume, but they also occur in the 3rd and 4th. 

 In the two first volumes there are none. 



The notes in vol. iii. are " PI. 75 before 1805, 

 „ 150 „ 1816, 

 „ 151 after 1822." 



vol. iv. are "To plate 74 before 1806, 



„ „ 100 „ 1816, 

 From „ 101 after 1822." 



vol. v. are " Pyralis before 1801 to fig. 141, 



Tortrix „ 1801 „ 194, 

 Tinea „ 1801 „ 258, 

 „ 1812 „ 2 j 3, 

 „ 1816 „ 444, 

 „ 1822 „ 450, 

 „ 1829 „ 470, 

 after „ „ 477." 



I believe these calculations were arrived at from reference to other works 

 published at such and such dates and noting where the references to Hiibner's 

 figures stopped. 



Nothing is more likely than that an author would refer to his own unpublished 

 Plates, if they were sufficiently advanced to enable him to do so. As a very good 

 case in point, I may cite what I am actually doing at the present time. I have two 

 volumes in the printer's hands ; vol. xi. of the " Natural History of the Tineina," 

 and the " Tineina of Southern Europe :" each of these contains references to the other, 

 and I am quite uncertain which will be first published. — H. T. S., Sept. l\th, 1869.]
