This remarkable insect will undoubtedly at some future period 
be regarded as the type of a new genus; at present I consider it 
as a Pholidotus, till enabled to figure the other sex. It is named 
in honour of M. Reiche, of Paris, possessor of a rich cabinet of 
Coleoptera. 
The figure, which was painted in Paris, is well done, and I am 
indebted to M. Guérin for it.

The above species is evidently allied to the Lucanus Rhinoceros 
of Fabricius ; it differs chiefly in having its mandibles bifurcate, 
whereas in Rhinoceros they are simply acute. [It is named in honour 
of M. Buquet, who possesses one of the chief cabinets of Coleoptera
