The following description is offered in order to provide a name which can be used by economic workers for a species of Argyrotaenia which is destructive to spruce foliage, and which has been erroneously regarded as lutosana Clem., following Robinson's misinterpretation of Clemen's species (Robinson, 1869, Trans. Am. Ent. Soc., II, 279, pl. VI, fig. 59). A subsequent paper dealing with the status of several species in this group is in preparation and more complete notes will then be included.
