DR. F. LEUTHNER ON THE ODONTOLABINI. 445 
small priodont specimens, in which they are likewise shining. Head apparently more 
quadrate, and the sides straight; the spine behind the eyes is oblique in large speci- 
mens, and straight in small ones. The mandibles differ from 0. dellicosus in being 
always more curved, and are more like those of (0. siva, but there are three basal teeth, 
which are sometimes fused into two in large specimens; in the amphiodont forms three 
are distinctly visible. ‘The prosternal process is well developed, and projects strongly 
in front and beneath. The mesosternal process is enormously developed, even in the 
smallest specimens, and projects strongly in front (as ia O. gracilis); front tibie with 
three spines above the terminal fork. 
Mandibles. 
1. Forma telodonta.—Mandibles longer than the head, slender, more curved than in 
O. gracilis and O. bellicosus, with four or five small apical teeth, strongly expanded 
inwards at the base, with two or three obtuse teeth (fig. 6). 
2. Forma amphiodonta.—Mandibles similar to those of O. bellicosus, with five apical 
and three basal teeth (fig. 7). 
3. Forma priodonta —Mandibles as in 0. bellicosus, but the upper surface strongly 
punctured (fig. 8). 
Female. Unknown.

I first met with this interesting form, which I consider likely to prove a well-marked 
local form of O. bellicosus, in the Museum of the Jardin des Plantes in 1882, where it 
was mixed with small specimens of 0. bellicosus. I subsequently received a large series 
from Celebes and Sangir through the kindness of Herr van Lansberge, whose MS. 
name IJ have retained.
