" The author proposes to commence, on the 1st July next, with 52 pages 

 of letter-press, instead of 16, as heretofore; to continue, at least, that 

 quantity monthly ; and to complete two volumes, with an index and appen- 

 dix relative to their contents, annually, on the 1st of June. But as it is 

 obvious that this arrangement cannot be carried into effect without consi- 

 derable increase of expense, the price of each number, from the above 

 period, will be advanced to five shillings; and in order to render the 

 volumes now in progress, of equal bulk and value with the succeeding, a 

 supplementary number, containing about 100 pages of letter-press, illus- 

 trated with three figures of lepidopterous insects, will be published on the 

 spth June next, completing the description of the Harpalidae, the Diurna, 

 and the Crespuscularia, the price of which will be eleven shillings. And, 

 as the printing of the author's Systematic Catalogue is rapidly proceeding, 

 and the catalogue itself is drawing to a close, the author is now enabled to 

 make a more correct statement of the extent of this work. He therefore 

 undertakes to complete, as far as practicable, the description of the insects 

 enumerated in his catalogue in 135 numbers, including the 12 already pub- 

 lished, so that his labours will cease in ten years ; and he trusts, that the 

 regularity with which the work has hitherto appeared, and the circumstance 

 of his having already exceeded the stipulated quantity of plates and letter^
