I have named the above insect in honour of tbe venerable Treasurer of the 

 Linnean Society, Edward Forster, Esq., a zealous pronsoter of Natural History 

 in general, and distinguished for his accurate knowledge of the more difficult 

 tribes of British Plants, and for his long and faithful services to this Society. J 

 have received it previously from Assam: the specimens in Mr. Griffitii's col- 

 lection are small compared with the one figured, which is from Dr. Cantor's 

 caljinet. It may l>e remarked respecting the Liicanhhc ui \.\\c East Indies, that 

 individuals of the same species are subject to vary very considerably in size, 

 arising perhaps tVom scarcity or abundance of food whilst they are in the larva 

 state, or periiaps in consequence of a want of sufficient moisture during sea- 

 sons of drought. It stems necessary that a third section should be formed, 

 to include those species of Stag-beetles Avhicli have five leaflets forming the 

 club of the anteimee. Two other remarkable insects from the island of Java 

 in my collection belong to the same section ; they are provisionally named 

 in my manuscripts as L.falc'iger and L. loiigipeu)iis ; and in a forthcoming 

 synopsis of the species they will be found minutely described.

The abcve-described insect «^as originally named in my collection in honour 

 of Sir Stamford Rallies, it ;ippears to l)e widely spread over the Indian con- 

 tinent, as I have seen it in collections from Nepaul, Bengal and Assam ; and.
