Mr. Saunders has figured in the 'Entomological Transactions' a Lucanus 

 from India, which he regards as a variety of Luc. bicolor of Fabricius, but 

 which is evidently a distinct species. I suggest, therefore, the name of Saun- 

 dersii being applied to that of the above-mentioned author, as it was originally 

 described by him : it belongs to the same genus as Odontolabis. Lucanus Bur- 

 meisteri of my cabinet is the type of a genus allied to Odontolabis, and is re- 

 markable for having all its tibiae unarmed, 



Sp. 3. Odontolabis Baladeva.
