Abstract:

Erora laeta (Edwards) has long been thought to occur in two widely separated areas; the first area consisting of parts of the northeastern United States and southeastern Canada and the second, of parts of the southwestern states. An investigation of the southwestern records has shown that they are based upon inaccurate determinations and that the two regions are inhabitated by two distinct species, Erora laeta in the northeast and Erora quaderna (Hewitson), a species originally described from Mexico, in the southwest. This will doubtless surprise many workers as the name Erora laeta (Edwards) is represented in most of the North American collections and museums solely by southwestern specimens. It seems less surprising, however, to find that this southwestern species is really a species found in nearby Mexico than a New England and eastern Canadian species not known to occur in any locality nearer than fifteen hundred miles distance. Erora quaderna is here recorded for the first time as occurring within the boundaries of the United States. Descriptions of the two species follow.
