 piceis; elytris convexis, infra basin prope suturamtransversim excavatis, 

 nigris, tenuissime punctatis ; thorace Isevi, sat profimde transversim

 obliquely converging towards the apex, anterior angle obliquely 

 truncate, armed laterally with a small obtuse tooth; upper 

 surface smooth, with a few scattered punctures on either side
