angles of the double arcuate, transverse sulcus. The elytra are high- 

 shouldered, convex, the sides arcuate, with the dorsal striae abbreviated 

 near the middle. The abdomen is at the base narrower than the elytra

The specimen described is in possession of Mr. H. Ulke.

The head is nearly as broad as the thorax, bifoveate between the eyes, 

 the grooves with a very short obsolete sulcus running forward. The 

 antennoe ai-e as long as the head and thorax conjointed, and of the usual 

 form of this genus. The last joint of the maxillary palpi is long, ovate, 

 acuminate. The thorax is longer than broad, rounded, densely punc- 

 tured, pubescent, with three basal grooves, connected by an arcuate 

 sulcus, branching out forward from the lateral grooves. The elytra are 

 , rectangular, longer than wide, half as broad again as the thorax, densely 

 punctured and pubescent, with very little impressed basal grooves in 

 the place of the faintly indicated dorsal stria;, and small punctures be- 

 tween it and the basal end of the sutural entire stride. The last two 

 segments of the abdomen are longer than the preceding segments. 

 It inhabits the Northern States.

I find that I had no good and sufficient ground for asserting on page

 withdraw that assertion.
