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

 very finely punctulate, and dense!}- clothed with short cinereous 

 pubescence. The body is less convex than in Serropalpua and 

 Dircaea.

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

 Dr Melsheimer. Differs from D. li(urata~Lcc.(S<rr. l-maculalus\\ 

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

 the more sericeous pubescence, and the shorter and Btouter 

 antennae, the joints beyond the 4th being nol longeT than wide. 

 The thorax is marked with a vague transverse impression jus! in 

 front of the middle. 



D. decolorata Randall, is perhaps Xylita laevigata, but 

 reference must be considered somewhat doubtful, and the types 

 are destroyed.
