LAMELLICORNS OF OLIVIER. 321 



Sp. 116. Janus. Apparently this insect is a Copris. I am 

 only acquainted with Olivier's figure, which corresponds with 

 Jablonsky's Scarabceus Berbiceus, so named from being found 

 mix Berbices. 



Sp. 123. Boreiis. This form of Copris appears to be pecu- 

 liar to the New World ; it occurs in North as well as South 

 America. I propose tlie name o{ Dickotomius,'^ to include all 

 insects allied to Cop. Boreus, Olivier. The following charac- 

 ters may be deemed sufficient, particularly as the type is well 

 known. 



" Caput cornutum, clypeo bidentato, seu fortiter incise : thorax, 

 antice retusus, (aiigulis anticis porrectis acutis), tricornis, cornu 

 intertnedio lato obtuso subemarginato, lateralibus divergentibus 

 subretusis : elytra septem striis insculpta : corpus infra ciliatum : 

 pedes femoribus supra depressis et infra subconnexis : tibiis com- 

 pressis postice dilatatis et subtrigonis." 



The Copridm of the new world appear to have but seven 

 stride on their elytra; those of the old continent have eight. I 

 have not yet examined all the species in my collection. Copris 

 Sabceus, and its allied species, belong to the typical Copris of 

 the old world. The following insects belonging to DicJio- 

 tomius will be found in my collection, viz. DicJiot. Brasiliensis, 

 crassus, neglectus, gagates, poUtiis, and others. 



Sp. 125. Momas. A Pkanccus of MacLeay. The charac- 

 ters of the subgenera composing the family PhancBidce, are 

 detailed in the Horae Entomological. 



Sp. 128. Splendidulus. Olivier asserts that this insect is 

 marked in the Royal collection at Paris, as inhabiting the 

 Island of Madagascar ; it is evidently a South American 

 species. 



Sp. 130. Paniscus. Olivier states his opinion, that this 

 insect is probably only a variety of Copris Hispanus, in which 

 I am inclined to agree with him. 



Sp. 134. Anceus. No locality is given by Olivier to this 

 species ; it was first described from the cabinet of M. Gigot 

 D'Orcy. I think it not unlikely that it may be an African 

 insect, and from the Cape of Good Hope, as some species 

 from that quarter closely resemble Anceus. 



Sp. 136, Pithecius. This species appears to be common to 



■^ From SixoTOfiia, a division into two parts.
