S. argenteomaculata Harris expands nearlythree inches, and is ashy gray, variegated with dusky cloudsand bands, with a small, triangular, silvery spot and rounddot near the base of the fore wings. Hepialus is smaller, witha larger head and straighter Avings. H. humuli Linn, isinjurious to the hop vine in Europe. Our most common spe-cies, H. 7nustelmus Pack., is sable brown, with sl
