 in Africa. 



The first type extends from the Atlantic Ocean to Thi-

 not yet been found ; and the fifdi inhabits all that tract of 

 country which extends from the AUantic Ocean to the 

 Chinese sea — from Paris to tne Cape of Good Hope. 



Creutzer, in his Entomologische Versuche, a little work 

 published in 1799, and containing many excellent obser- 

 vations on the science, has stated, that S. sacer, laticoUis,

 possess that character which lUiger had assigned to the 

 genus Copris. In other words, they have not the middle 

 feet distant at their base. On the contrarj', it is remarked 

 by Creutzer, that their middle coxae are as near to each
