" Mr. W. S. MacLeay's great Family of CetoniadcB constitutes, I think, a 

 Stirps rather than a Family y and appears to contain at least three larger groups, 

 each resolvable into various others — viz. Trichiadce, Cetoniadce^ and Gymneti- 

 da. The first including Trichius F, Cremastocheilus, &c. ; the second those 

 CetoniadtE without a lobed prothorax; and the third those in which that part 

 is lobed, and covers the scutellum. — '' As Knoch's Neue Beytrdge is not a 

 common book, I have given from him in part the characters of Cremastocheilus.
