NEW CHERNETIDÆ FROM THE UNITED STATES
Since my last article ont his group Can.Ent., Aug.,1891), I have obtainded quite a number of forms; some of the new ones are described in this article. Two genera, new to the U.S., are recorded, both of which occur in South America. Chelifer alius, described by Leidy in Proc. Phil. Acad. Sci., 1877, agrees, as far as description goes, with Chelanosp oblongus, Say and with no other form known to me, therefore I consider it a synonym of C. oblongus.
