Rev. W. Kirby's Characters of Otiocerus and Anotia. 13 



lent diagnostic marks by which the natural genera may be readily 

 ascertained. Amongst the insects of this family, which I pur- 

 chased at the sale of the late Mr. Francillon's Museum, 1 found 

 seyeral that would not well arrange under any of M. Latreilles 

 present genera ; but I was particularly struck by a set collected 

 in Georgia, and admirably displayed by that expert collector, 

 accurate delineator and painter, and most intelligent observer of 

 natural objects, Mr. Abbot. Upon examining these attentively, 

 I found that they clearly formed two nondescript and very distinct 

 genera belonging to the subfamily of FnlgorelUc of the great en- 

 tomologist before alluded to. 



1 now beg leave to lay before the Linnean Society the charac- 

 ters of these two genera, with a description of the species in my 

 cabinet.
