T cannot separate this species (tyjie of tlie proposed 

 genus Olarh) from the genus Tricenlrus. 'I'he type of 

 O. auritiis is now before me, and I think tliat Buckton 

 must have originally described from a niutihitcd specimen 

 and afterwards ol)tainod a perfect example wliich he marked 

 as type. I am forced to this opinion, as he writes of tlie 

 '■ posterior horn " as " ahnost obsoh'tc," and, again, "the 

 ])osterior iiorn is l)lunt," The posterior pronotal process is, 

 however, normal, slightly passing the posterior angle of the 

 inner tegminal margin, and its apex is distinctly narrowed 

 and acute. It is, however, a species very broad compared 

 with its lenjrtli.
