This beautiful insect nearly corresponds in structure with the 

 Scarabwus longimamts of Linnaeus ; a sketch of the anatomy of 

 which has been obligingly handed me by Mr. Westwood ; it 

 is, however, I am led to believe, a perfectly distinct species. 

 It is said to have been taken at Smyrna, but appears to me 

 rather more of a Brazilian than European or Asiatic form. 

 The only specimen I have seen is in the rich cabinet of Mr. 

 Hanson. 



Genus. — Scarabwus. Linnaus. 



I know of no group in Entomology that calls so loudly for 

 further generic division as that immense mass known by the 

 common appellation of Scarabwus, or, according to some 

 authors, Dynastes ; and, in Fabricius, described under the 

 name of Geotrupes. The separation of an isolated species or 

 two as the proposed genus Propomacrus for the reception of 

 Arbaces, and perhaps longimanus, is altogether insufficient, and 

 is a task from which I would most willingly have shrunk. 



Scarabaeus Croesus. Totus testaceus ; pedibus mllosis. Tab. xiv. 

 Icon. :2. 



There are several examples of this fine insect in the London 

 cabinets, all of them, I believe, imported from Jamaica by Mr.
