“A more elongated insect than the other two conti- 
nental Asiatic species (N. cornutus and N. obesus), and 
differing from all the allied species in wanting the erect 
tooth, or horn-shaped dorsal apophysis of the mandibles. 
The sides of the head are rounded before the eyes, and 
not produced into a point; the thorax has the lateral 
margin excavated in the middle. The sulci of the elytra 
are wide and deep, and have a chain of fovez, but are 
destitute of the lines of fine punctures seen in N. lwvwi- 
collis; the interstices are narrow, polished, and impunc- 
tate.” 
In addition to the above character given by Mr. 
Bates, it is to be noticed that the clypeus is produced in 
front into an obtuse point, the disc of the head is fur- 
nished with a central impression, deepest behind. The 
eyes are completely divided by the canthus; the maxillz 
have the inner lobe armed with a strong horny tooth, 
which leads me to suppose that the specimen described 
by Mr. Bates and the one here figured, are females. The 
mentum is very deeply emarginate in front, and widely 
punctured ; the anterior margin of the pronotum is 
narrowly depressed, strongly punctate, behind which the 
disc is raised on each side, with a sharp small central 
raised tubercle. The striz of the elytra, near the suture, 
are slightly curved, and not parallel therewith ; the an- 
terior tibize have seven or eight teeth on the outer 
margin, and the four hind tibie have a rather strong 
central spine, preceded, in the middle pair by three, and 
in the hind pair by two, more minute spines.
