ODONTOLABIS 1NTERMEDIUS. 225 



NOTE XL VI. 



ON A NEW SPECIES OF THE LUCANOID GENUS 

 ODONTOLABIS, HOPE. 



J. R. H. NEERVOORT van de POLL. 



The new species of Odontolabis described below originates 

 from Palawan , one of the Philippine Islands , situated be- 

 tween the northern part of Borneo and Luzon , and forms 

 a most interesting connecting link between O. alces F. 

 from Luzon , and 0. celebensis Leuthn. from Celebes , bearing 

 in general appearance even a greater affinity to the last 

 named species, the dentition of the mandibles however 

 corresponding with 0. alces F. The great length of the 

 mandibles, which in the mesodont form are longer than 

 the head and prothorax together, is very remarkable and 

 unique for the so-called a/ces-group. Now British North 

 Borneo becomes the more and more explored , I have some 

 hope, that, within a short time, an allied form from Bor- 

 neo will also be brought to light, which I consider to be 

 of high importance for the real appreciation of the allied 

 species, scattered over these islands. 



Odontolabis intermedins, v. d. Poll. 



Male. Uniform deep black; mandibles, head, prothorax 

 and legs dull, very finely punctured; elytra pitchy black 

 with a bright obsidian lustre. Head large, quadrangular, 

 much longer than the prothorax , front edge strongly emar- 

 ginate , sides straight in front , canthus very narrow, post- 

 ocular tubercles very much developed, obtuse and strongly 

 directed forwards, the lower part of the cheeks coarsely
