the stria3 of the elytra have become obsolete, the apex of 

 the mandibles blunt, and the teeth of the tibiie consider- 

 ably worn down, thus modifying its usual appearance ; and 

 Say's description appears to me to afford nothing opposed 

 to this view. 



Fam. Odontolabid^. 



The genera Odontolabis, Chalcodes, Uetcroclithcs and 

 Neolucanus, hitherto located in the Lucanulce, present the 

 following characters in common wliich distinguish them 

 generally from the Lucanidm and Chnlognathuhe, and are 

 sufficient, in my opinion, to entitle them to rank as a 

 distinct family. 



Clava of antennce tri-articulate, the leaflets being but 

 moderately produced. 



CJypcus remarkably small, considering the size of the 

 insect. 



Eyes divided in both sexes by a can thus. 



Tihice : anterior tibiae in the males often considerably 

 curved, their external armature very variable. Four 

 posterior tibiae in both sexes invariably unarmed. 



The majority of the species are of large size, and 

 chiefly bicolorous. 



Odontolabis Burmeisteri, Hope. 



At the time of preparing my former Catalogue a single 

 specimen only ( $ var. max.) , in the Hopeian collection 

 at Oxford, was known, and I ventured the suggestion 

 that the insect might possibly prove to be only an extreme 

 variety of 0. Cuvera, Hope. Count Mniszech has recently 

 received from the Mysore, a specimen of the var. minor, 

 and assures me that 0. Burmeisteri should be accepted as 

 a distinct species. 



Odontolabis Castelnaudi, Parry. (PI. III. figs. 4, 5, 6.) 



When notifying this very rare species from Sumatra, 

 two specimens only were known to me, one in my 

 own collection (var. med.) and the other (var. minor) in 

 that of M. Laporte do Castelnau. Recently Count 

 Mniszech has obtained a specimen of the var. max. from 

 the same locality. Figures are now given showing the
