Treutscke, and the latest writers on the order Lepid6'ptera, and engraved 

 on stone by Meigen himself, with such accurgfcy as to supply the place of 

 more expensively coloured works. The price of each heft, containing ten 

 plates, and each plate from 6 to 12 figures (including reverses) is in Ger- 

 many 2 dollars, or 6 shillings English, for the uncoloured copies, and 6 dol- 

 lars for a very limited number of copies coloured by the author. The above 

 two works are deservedly favourites with my two boys, and by them they 

 have named nearly all their collection of Lepidoptera. Any London foreign 

 bookseller that would import several copies of these works, would equally 

 serve himself and young English lepidopterists. — W. S. Brussels, Jan. 22.
