. The Canadian entomologist. Insects; Entomology. THE CANADIAN ENTOMOLOGIST 189 although the genus in its present form has acquired a number of specialized characters. The neuration of the fore wings in the three genera just mentioned can easily be derived fron that of Corythophora. The absence of vein 11 is not significant, but is of recent disappearance, as it is virtually absent in one species of Proleiicoptera while present in the other, and thus can not be considered as a character of im- portance. However, the fact that vein 4 is here present and oc- cupying its normal position would suggest that a slightly different interpretation should be put upon the venation of Proleiicoptera, ^'iz., that vein 3 is absent and not 4, as stated by Mr. Busck in his characterization of that genus. The derivation of the neuration of the hind wings of the \-ounger genera from this type is not so obvious. However, the examination of the hind wing of Proleiicoptera smilaciella Bsk. discloses a feature hitherto overlooked, which shows clearly its origin from the present genus. As shown in the accompanying figure (Fig. 2), veins 5 and 6 are stalked from the base and distinctly separate from 7 toward base, but almost anastomose with it along the middle of the wing, becoming separate again where they branch. Its affinities with Tineid stock are at once apparent; in fact, its neuration closely approaches that of some of the Tineid genera. This furnishes strong confirmatory evidence of the Fis;. 1"J.—Hind wing of Prolcucof^tera smilaciella , r i • r ,1 descent ot this group trom the Tineidci\ from which it has been regarded as derived. Corythophora aurea, n. sp. Head and appendages very pale yellow, flap of scales on basal segment of antennae somewhat deeper yellow. Thorax pale yellow or white, patagia golden yellow. Fore wings golden yellow, deepening toward the apex, where the colour is deep orange. Costal margin from l/5 to just beyond the begin- ning of the cilia, and dors
