My attention having recently been drawn to the “Historical sketch of the Generic Names Proposed for Butterflies, a contribution to Systematic Nomenclature, by S. H. Scudder, Salem, 1875,” in which some hundreds of names have for the first time been advanced, I was led to investigate for myself the sources whence part of them were derived, especially the works of Hübner.

Eyes naked, tibiae unarmed, tufting of body obsolete, so that it approaches oligia, but is stouter than those species. Fore wings light gray. basal line black, distinct; t.a. line geminate, black outwardly and white inwardly, irregular; t.p. line geminate, produced above the reniform, curved outward, joining the reniform inferiorly.

The writers who are engaged in the work of giving us an account of the different kinds of Butterflies and Moths inhabiting North America, seem to fall into two categories with respect to their ideas of classification. As in other departments of Natural Science, the Entomologists differ principally in their conception of what constitutes a genus. They are either lumpers, making their genera very wide, or splitters, making their genera restricted and dependent upon less conspicuous details of structure.
