A very distinct genus, containing one species of large size, 

 very finely punctulate, and densely clothed with short cinereous 

 pubescence. The body is less. convex than in Serropalpus and 

 Dirceea.

One specimen, from York County, Pennsylvania, given me by 

 Dr. Melsheimer. Differs from D. liturata Lee. (Serr. 4:-maculatus\\ 

 Say) by the absence of spots, the finer and denser punctuation, 

 the more sericeous pubescence, and the shorter and stouter 

 antennae, the joints beyond the 4th being not longer than wide. 

 The thorax is marked with a vague. transverse impression just in 

 front of the middle. 



D. decolorata Randall, is perhaps Xylita Isevigata, but the 

 reference must be considered somewhat doubtful, and the types 

 are destroyed.
