In 1941 Doctor Robert Usinger set up the new Subfamily Potamocorinae for <I>Potamocoris parvus</I> Hungerford, which was described in the same issue of the Annals of the Entomological Society of America, Vol. XXXIV, pp. 1-4, Plate I. This tiny species, only 2.8 mm. long, appeared to be a most interesting discovery, and remarkably smaller, and structurally different from any Naucorid known. Recently there has come to my attention another new species of about the same size, but with characters that place it in another genus and add strength to the suggestions of Doctor Usinger and Mr. W. E. China that there is some close relationship between the Naucoridae and the Helotrephidae.
