The above insect, which is the largest species of Hexarthrius known, was 

 obtained in Silhet; it is described from the rich oriental cabinet of Frederick 

 Parry, Esq., and is named in honour of that zealous entomologist.

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

 from India, which he regards as a variety of Luc. bicohr 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. 



Niger, mandibuiis porrectis multidentatis, capite thoraceque utrinque uniden- 

 tatis. 



Long. lin. 26 ; lat. 10. 



Habitat in Silhet. 



Caput antice et postice sinuatum. Mandibulm porrectae arcuatae, capite parum longiores. 

 Thorax utrinque dentatus, laevis, foveolis rotundatis binis postice impressus. Elytra 

 glabra, nitida ; tibiis anticis externe denticulatis, quatuor posterioribus inermibus.
