PI. II, Fig. 11. 



This species is represented only by a couple of elvtra, one of them 

 accompanied by a leg. It differs from the preceding in the coarser punctures 

 of the striie, which are so heavily impressed as to involve slightly the sides 

 of tiie interspaces and give th(> ])unctin"es somewhat of a transverse appear- 

 ance: they are als(» separated l)y a less distance from each other, and the 

 alternate interspaces are somewhat more elevated than the intermediate 

 ones. The femora show .scarcely any sign of any internal apical emargina- 

 tion, are largest in the middle, and not in the ajiieal half; the tibia' are 

 scarcely expamled a])icallv and of nuu'li sleii<lerer form.
