294 STAG-BEETLES (FAM. LUCANIDAE) 



excavation there is a small but distinct thorn ; the scutellum 

 with some few punctures; the eMra are shining, in the 

 middle densely but very finely punctured ; the base, the sides, 

 and the tips more strongly punctured ; the humeral angles 

 rounded. Each elytron shows a distinct stria in form of a slit 

 which begins laterally of the shoulder and ends near the tip. 

 Outwards of this stria and in the posterior half of elytra there 

 is one short and inwards two longer hardly visible cortae. 

 The mentum is very rugous: the metasternum and the 

 chancelled epipleura deeply punctured ; the front tibiae have 

 4—5, the middle and hind tibiae 1 large tooth. 



Long. Corp. 38 mm. latit. prothorax 15 mm. ; elytra 16 mm.

Neolucanus borneensis Houlbert.

Is of the same chestnut colour as N. mimtjae Gestr. (Ann. 

 Mus. Civ. Genova, xvi, 1881. p. 314, fig. Leuthner ; 

 Monogr., 1885, p. 422.) The above described female is 

 completely conformable with A'', horneensis but is black in all 

 parts. It is possible that the coloration of N. horneensis 

 varies from chestnut to black, but before this inconstancy of 

 the colour has been proved by a long series of specimens, the 

 new subspecies must be kept up. 



The type in the Sarawak Museum.
