To JoHK George Cbildren, Esq. F. R. S. Sfc* 

 My dear Sir, 



I send you a Monograph on a Family of Insects, having 

 Cebrio for its type, which was written in the year 1815, and in- 

 tended for my Zoological Miscellany ; I have looked it over, and 

 corrected it, and now send it to you for the New Journal, in which 

 you are one of the Editors ; together with the description of two 

 undescribed species of Insects, belonging to a genus established 

 by Latreille, under the name Phengodes. 



I remain, my dear Sir, yours most sincerely, 

 December 19, 1823. William Elfoud Leach.
