Male. Uniform deep black, head, pvothorax, 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 ; prostcrnal process rounded, well developed ; 

 mesosternal process not prominent ; front tibiae long and narrow, with three well- 

 developed spines above the terminal fork. 



Mandibles. 



1. Forma teJodonta (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 straigjit ; 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 0. 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 epecimens in the collections of Hcrr van Ltinsberge and the Jardiu des Phmtcs (fig. 1) the twu 

 basal teeth have disappeared (fig. 1). These ajtproach a true mesodout form, which is most developed in 

 0. alces (PL LXXXIX. fig. 3). 



' By an oversight, the amphiodont form was not figured. It most re.=embles the same form of 0. cehhemsk 

 (PI. LXXXVIII. fig. 7).
