 almost imperceptibly rounded anteriorly, front angles depressed, the 

 posterior nearly rectangular, but not prominent ; its punctation nearly 

 similar to that of the head. ScutcUuin punctulate. Elytra slightly broader

 and with a smaller impression before the scutellum ; the surface bears

 Elytra not much longer than broad ; a little broader than thorax ; their 

 sides and apex nearly vertical ; striate-punctate, with a large compressed 

 elevation on the third interstice at the base, and two others behind, the 

 one on the summit of the posterior declivity the larger; three others 

 nearer the side are placed further back, the anterior being near the 

 middle of the elytron; they are clothed with a few yellowish setae. Legs
