2. Odontolabis duivenbodi, R. Oberthiir, Ann. Mus. Genova, xiv. p. 566. 
Male. Very like O. stevensi. Chestnut-brown; head and mandibles darker brown. 
Head agreeing with O. stevenst in form and sculpture; prothorax reddish brown, nar- 
rower, the sides straighter, middle spine rounded off; mandibles more variable than in 
O. stevensi; elytra flattened, tricolorous, outer margin yellow, followed by a narrow 
black stripe from the shoulder to the tip, and the space between this and the suture is 
reddish brown; rim of the elytra beneath black; front tibie long and straight, with 
two or three spines above the terminal fork. 
Mandibles. 
1. Forma telodonta (fig. 5).—Mandibles as long as the head and prothorax together, 
jong and slender, with only two or three very small apical teeth. Epistoma broad, 
triangular. 
2. Forma mesodonta.—(a) Mandibles as above, with a rather long tooth beyond the 
middle (fig. 6); (6) Mandibles with two well-developed middle teeth (var. didentata) 
(fig. 7). 
3. Forma amphiodonta.—Mandibles hardly as long as the head, broad, strongly 
curved, with five apical teeth and an obtuse basal tooth. 
4. Forma priodonta.—Mandibles broad, scissors-shaped, with eight or nine irregular 
teeth on the inner side. Epistoma triangular (fig. 8). 
Female. Very like that of O. stevensi; brown, except the elytra. Head as in 
QO. stevensi; prothorax likewise of similar form, but conspicuously narrower; elytra 
tricolorous, the intermediate stripe, which is black outside and brown inside, begins at 
the shoulder, and narrows gradually to the tip; under-surface uniform dark rust- 
brown; front tibie as in 0. stevensi, but not so broad, with three or four very small 
spines above the terminal fork ; four hinder tibiz straighter. 
Number of specimens examined: ten males and five females. 
Habitat. Sangir.
