LAMELLICORNS OF OLIVIER. 317 



attenuated, evincing their South American relationship to 

 Pholidotus. 



Sp. 12. Cancroides. For the present, I have attached the 

 generic name of Lucanus to this species ; it appears, however, 

 according to ray views, to afllbrd sufficient characters for a 

 subgenus.^ 



Sp. 16. Rhinoceros. I cannot help suspecting that this 

 insect is an Asiatic species, as it closely approaches several 

 East Indian individuals. 



Sp. 17 a?nd 18. Bicolor and Camelus. On the authority 

 of M. Westermann of Copenhagen, I give the East Indies as 

 the true locality of the above insects. It is not improbable 

 that they are the same species ; the former may be considered 

 as the immature state of Luc. Camelus. There are some 

 specimens in the original collection of Sir Stamford Raffles, 

 (now belonging to the Zoological Society,) which accord well 

 with Olivier's figures. 



Sp. 20. Zebra. No locality is given to this species by 

 Olivier ; from the figure it appears to be an immature insect. 

 I give the East Indies as its locality, with some doubts. 



Genus II. — Scarab^us. 



Sp. 2. Sc. Jlcides. Fabricius and Olivier, in their respec- 

 tive works, report this insect as inhabiting the East Indies ; 

 they are both in error, as it is found in South America ; and, 

 like ^6". Perseus, is only a variety of Dynastes Hercules. 



Sp. 6. Elephas. Now a Megasoma of Mr. Kirby. Olivier 

 mentions Guinea as its native country : it is evidently an 

 insect of the new world, and certainly not one of the old. 



Sp. 7. Typhon. This, like the preceding species, is also 

 a Megasoma. It inhabits Bahia, from which country I have 

 twice received it ; apparently, from the numbers I have seen, 

 it must be very abundant. Olivier does not give its locality. 



Sp. 9. Centaurus. Now a Xylotrupes, Hope. Olivier 

 asserts that this insect inhabits the East Indies, as well as 

 Africa. I have received it from Guinea, and cannot help 

 thinking the former locality is erroneous. 



Sp. 10. Gedeon. Probably Gideon; the former being a 

 misprint. 



' Mr. Westwood has described and figured this species as Dorcus Cancroides, 

 at p. 267 of this Volume of the Entomological Magazine. — Editor.
