Sp. 17. Mimas.— This splendid insect belongs to 

 Mr, W. Sharpe MacLeay's genus Phanseus. In 

 the Horse Entomological will be found about twenty 

 species described, several of them are apparently 

 unknown to the French writers, as the Baron De 

 Jean only mentions two species to which Mr. 

 MacLeay's names are attached. 



Sp. 18. Sacer. — Now the type of Mr. MacLeay's 

 genus Scarabseus, and subgenus Heliocantharus. 

 It is singular that the same remark which has been 

 made respecting the species of Phanseus may also 

 be applied to those of Scarabseus, two of Mr. 

 MacLeay's names only being cited, and these being 

 sunk down into synonyms. Whence arises this 

 omission ? purposely or not ? does it proceed from 

 a national jealousy ? I trust not. Does it arise 

 from a want of individual exertion and industry ? 

 if so, it is to be hoped that some Entomologist will 

 yet arise and undertake an interesting monograph, 

 embodying in it Mr. MacLeay's observations, and 

 inform the Continent what has been done since that 

 writer quitted England, now a period of nine years. 



Sp. 24. Nuchicornis. — Now of the genus Ontho- 

 phagus, which requires however to be divided into 

 several subgenera. I am acquainted with more 

 than three hundred species, the major part of
