These two sets of characters are designed to point out the dif- 
ferences between two distinct families of Scarabeide 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 Linn., farctus Fabr., Lazarus Fabr., Cyclops Oliv. &c., be- 
long to one of these families; and Sc. Typheus Linn., dispar Fabr., 
Momus Fabr., stercorarius Linn., foveatus Marsh., Mutator Marsh., 
splendidus Fabr., sylvaticus Fabr., hemisphericus Oliv., and verna- 
lis
