Dedicated to my friend, Mr. L. O. Howard, of the U. S. Department 

 of Agriculture. In the highly polished surface, entire ab.sence of parap- 

 sidal furrows, striated scuteilum, r lie bare metapleura, and the long tail, 

 it is quite distinct from all other di^scribed forms in this peculiar genus.
