These two sets of characters are designed to point out the dif- 

 ferences between two distinct families of Scarabaida that have 

 hitherto been considered as belonging to the same genus. Sc. mo- 

 bilicornis Linn, (of which -Sc. testaceus Fabr. is only a variety), qua- 

 dridens lAnn,, farctits Fabr., Lazarus Fabr., Cyclops Oliv. &c., be- 

 long to one of these families; and Sc, Typhceits Linn., dispar Fabr,, 

 Momiis Fabr., stercorarius Linn., foveatus Marsh., Mutator Marsh., 

 spkndidus Fabr., sylvaticus^&hr., hemisp/uericus Oliv., and verna- 



lis
