The following description of the characteristics of the family is adapted from Hampson with reference to the forms found within our fauna! limits: 'Proboscis fully developed; palpi upturned and well devel- oped, the third joint usually naked and porrect; frons with a rounded, conical, or corneous process; antennae cylindrical, almost simple, with slight bristles at the joints, not ciliated, and more or less distinctly dilated toward the extremity. Ocelli present; eyes sometimes hairy; tibial spurs well devel- oped, the tibiae rarely spined; the raale claspers often very large; wings large and strongly formed. Fore wing with vein la separate from ih; U" absent; 5 from or from close to angle of cell; the areole present in nearly all the genera. Hind wing with vein la present; ic absent; 5 obsolescent from angle of discocellulars; 6, 7 from upper angle or shortly stalked; 8 free at base, then bent downward to anastomose with the cell at a point only. All the species have silvery blue scales on the fore wings. The larvae are noctuiform and have all the prolegs present. The pupa is naked.' Genus COPIDRYAS Grote Two species belonging to this genus occur within the limits of the United States. We give illustrations of both of them.
