The femple of ih\^ species i'? vevv similar to that of O. loirH. 

 as alreadv pointed out hv v. "Rothenhnre- and Mollenkamp. 

 "Rnt both of. them seem to have overlooked the following; t^ro 

 differences : The prosternal procpss of O. lowei is larsie and 

 vaulted and the tin directed dov^^nwards and backwards: the 

 onter marofin of the elvtra in the first third is not broadly 

 turned horizontalh/. Tn C) . Irnfhn^ri (O) the posternal 

 process is narroT\- in form ns a keel, the tip truncated and not 

 directed backwards. The anterior margin is broadly turned 

 horizontalb . v. l^othenhurfT savs in his diagnosis of the female 

 that the elvtra are moderafphi shining. Tn the above-men- 

 tioned specimen thp ph.'tra are very Instrons and therefore it 

 mav be possible that it is the female of the variety described 

 below.

This variation difPprs from 0. Iriiflinrrr hv the dark chestnut 

 f^oloration of the elvtra and the denticnlation of the mandibles 

 in the forma telodonta. The sntnre is ac.comnanied by a row 

 of fine bnt di-^tinct nnnctnres ; other rows may be seen only 

 with the glass ; the onter parts of the elvtra are somewhat 

 granulated at the shoulders. The scutellum is deeply pimc- 

 tnred. The semi-circular mandibles show at the inner ma.r^n 

 near the base a little thickening as the rest of a very little
