9. Lucanus ursus, Cast. 1. c. p. 171, pl. xvi. fig. 2 (bad figure). 
Male. Uniform deep black, head, prothorax, and legs dull, very finely punctured ; 
elytra pitchy black, with a bright obsidian lustre; head shorter than the prothorax, 
broad, quadrangular, narrow in front, oblique on the sides, wider towards the spine, 
which is straight and horizontal; frontal edge always emarginate, with no raised 
crest; prothorax broad, trispinose, with two deep concavities ; under-surface smooth, 
the lateral margin coarsely wrinkled; prosternal process rounded, well developed ; 
mesosternal process not prominent; front tibie long and narrow, with three well- 
developed spines above the terminal fork. 
Mandibles. 
1. Forma telodonta (fig. 2).—Mandibles as long as the head and prothorax together, 
flattened, the sides nearly straight, more or less incurved at the tip, with three or four 
small teeth; near the base they are thickened on the inside, and armed with three 
teeth, of which the third from the base is most developed’. 
2. Forma amphiodonta’.—Mandibles longer than the head, the sides straight ; four 
or five small apical teeth, separated by a gap from the three basal teeth (0. vishnu, 
Hope). 
3. Forma priodonta (fig. 3)—Mandibles rather longer than the head, straight, and 
slightly curved inwards, with from eight to ten isodont and crowded teeth, without 
gaps; head flattened; under-surface of the border of the prothorax smooth, not sculp- 
tured (0. serrifer, Hope). 
Female. Very like that of O. siva, Hope, but more slender, uniform black; elytra 
strongly shining; head broad, convex, strongly and coarsely punctured; canthus broad ; 
mentum coarsely shagreened, somewhat raised on each side; mandibles very strongly 
sculptured; prothorax as broad as the elytra, the central spine strongly developed, 
‘ In two specimens in the collections of Herr yan Lunsberge and the Jardin des Plantes (fig. 1) the two 
basal teeth have disappeared (fig. 1). These approach a true mesodont form, which is most developed in 
O. alces (Pl. LXXXIX. fig. 3). 
? By an oversight, the amphiodont form was not figured. It most resembles the same form of O. celebensis 
(Pl. LX XXVIII. fig. 7).
