$ . Tlie head is strongly rugulose in front of the sutural 

 Ciuina, which is more pronounced than in tlie male, and 

 punctured behind it. The clypeal margin is sub:vngulate 

 and the ]i(sterior margin of the head bears an el'vated trans- 

 verse himina which is cniargiiiate at its upper edge. The 

 protl.orax is closely and coarsely punctured. The spur of 

 the front tibia is slender and acute. 



This species resembles 0, seniculus, F., the male of which 

 is without cephalic armature, but the processes upon the 

 prothorax attain a greater development in that insect, and 

 the clypeus is less developed in front as well as behind.

Niger, nitidus, corpore lateraliter brunneo-hirto, antennis pallide 

 testaceis ; clypeo ruguloso ; prothorace hand fortiter punctato, 

 postice Iseviore, medio obsolete sulcato, antice excavato, lateribus 

 basique marginatis, basi medio angulata, angulis posticis obso- 

 letis ; elytris striatis, iuterstitiis plauis, subtiliter punctulatis. 



S . Capita antice fere acute angulato, medio sat fortiter bicuber- 

 culato, postice retrorsum producto, cornu recurvato, acuminato, 

 basi lato quadrato ; prothorace antice valdo retuso, supra leviter 

 emarginato. 



2 . Capite autice arcuato, parum producto, medio fortiter recte 

 carinato, postice breviter producto, processu erecto truncate ; 

 prothorace antice paulo excavato, supra bituberculato. 



Long. 15-19 mm. 



Jlah. N. India, ^lanipur. 



Black and shining, with testaceous anteniiBS and reddish- 

 brown iiair at the sides of the sternum and abdomen. The 

 form is short and compact and the sculpture fine. The pro- 

 thorax is smooth and very sparingly punctured above ; it is 

 distinctly n)argined at the sides and base, the base is distinctly 

 angulated in the middle and the hind angles are rounded 

 away. The elytra are distinctly striated and the interstices 

 slightly convex and feebly punctured. Tbi pygidiura is 

 moderately punctured. The front tibiae are broadly quadri- 

 dentate and the first joint of the middle and hind tarsus is very 

 large and flattened. The tibial spurs are blunt and that of 

 the front tibia is strongly bent. 



(J . The clypeus is rather elongate and pointed, with the 

 sides straight. The clypeal suture is marked by two strong 

 tubercles, which divide the width of the head into three 

 nearly equal parts. The posterior part of the head is smooth 

 and produced backwards into a lamina, which narrows into a 

 slender recurved horn. The prothorax is excavated and 

 rugosely punctured in front and scarcely punctured behind,
