588 Rev. F. W. Hope on some Nondescript Insects from Assam. 
Nigro-piceus ; mandibulis valdé exsertis interné multidentatis ad basin dente 
valido suprà et infra armatis, apicibus furcatis. Tas. XL. fig. 1. 
Caput depressum, creberrimé punctulatum. Thorax convexus, subtilissimé 
punctatus, nitidus, lateribus extrorsüm serratis. Elytra piceo-castanea. 
Pedes concolores, tibiis mediis unidentatis, posticis inermibus. 
I have named the above insect in honour of the venerable Treasurer of the 
Linnean Society, Edward Forster, Esq., a zealous promoter 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. I 
have received it previously from Assam : the specimens in Mr. Griffith's col- 
lection are small compared with the one figured, which is from Dr. Cantor's 
cabinet. It may be remarked respecting the Lucanide of the East Indies, that 
individuals of the same species are subject to vary very considerably in size, 
arising perhaps from scarcity or abundance of food whilst they are in the larva 
state, or perhaps in consequence of a want of sufficient moisture during sea- 
sons of drought. It scems necessary that a third section should be formed, 
to include those species of Stag-beetles which have five leaflets forming the 
club of the antennæ. 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. falciger and L. longipennis; and in a forthcoming 
synopsis of the species they will be found minutely described. 
Spec. 2. Lucanus RAFFLESII. 
Long. unc. 2, lin. 6. Lat. lin. 8. 
Niger, nitidus; mandibulis valdé exsertis ante apicem unidentatis, apicibus 
obtusis obliquè truncatis. 
Caput latum, depressum, creberrime punctulatum. Thorax capite paulld latior, 
marginibus undique elevatis, elytris nigris glabris, pedibus concoloribus. 
Habitat in agro Assamensi variisque Indiae Orientalis regionibus. 
Affinis L. nepalensi, at major. 
The above-described insect was originally named in my collection in honour 
of Sir Stamford Raffles: it appears to be widely spread over the Indian con- 
tinent, as I have seen it in collections from Nepaul, Bengal and Assam; and,
