This is one of the most extraordinary species of the great Scarabeei of Linnaeus. 
The specimen here figured was purchased by the late Mr. Tunstal, from the cabinet of 
a Dutch governor in the East Indies, with other rare species figured in this work. At 
the period of the first publication of this work it was considered unique, and was 
regarded as an inhabitant of the island of Amboyna, in the East Indies. Linnaeus, 
Fabricius, Madame Merian, and Margrave, give South America as the locality of the 
insect described in the works of the two former authors under the name of Scarabaeus
