In this species the third and sixth ridges of the elytra of fe- 
males and small males taper away behind, and their union is only 
faintly indicated (see pl. xxix, fig. 3).

A single male of this species has been presented to us by the 
Agricultural Research Institute. It is very small (12°3 mm. long), 
but the dorsal tooth on the punctured and glossy mandibles is so 
long and slender (pl. xxix, fig. 5) that I think the specimen must be 
a large one of its kind. Below and slightly proximal to the 
dorsal tooth is an obsolete ventral tooth as in Dorcus rugosus, 
Boileau, from which the species may be distinguished by its black 
colour and imperfectly divided eye. The punctured and finely 
roughened clypeolabrum is keeled above the margin, but the keel 
is low and is not more pronounced laterally than medially ; though 
perfectly distinct, it is not at all conspicuous. The prosternum, 
too, is that of a Eurytrachelus, not a Dorcus!. 
The anterior angles of the head are rounded and slightly prom- 
inent; the oblique anterior surface of the head is lightly con- 
cave and finely roughened between them; the remainder of the 
upper surface is glossy, and the whole is strongly punctured. 
The mentum is very coarsely punctured ; it is roughly trapezoidal 
with strongly rounded anterior angles and very faintly concave 
anterior margin. 
The pronotum is glossy and more coarsely punctured than 
the head; it is vaguely sulcate in the middle line. The anterior 
margin is convex in the middle. The anterior angles are acute 
and very strongly produced forwards by the side of the head. 
The sides are divergent and lightly convex. The posterior angles 
are replaced by a lightly concave margin. The posterior margin is 
faintly convex. 
! Since the above was written a specimen of Boileau’s species has been 
presented by Mr. H. E. Andrewes. It proves to belong to the genus Eurytra- 
chelus, not Dorcus. E. rugosus and E. travancorica are practically identical in 
structure apart from the slightly shorter canthus of the latter.
