More closely allied to A. nysscEfoUella than to any other species, but the more reddish colour and the more slender fascia will separate the two species. Obrussa, new genus. Head and face tufted. Antenna 2/3, simple in d^, basal seg- ment enlarged and concave beneath to form an eye-cap. Labial palpi well developed, porrected. Maxillary palpi long, fiUiform, folded. Tongue rudimentary'. Posterior tibia; with spines above; middle spurs above the middle of the tibia?. Fore wings elongate ovate; lb simple at base, 2 becoming obsolete shortly beyond transverse vein, which closes the cell before the middle of the wing, 3 and 4 absent, 5 and 6 stalked, the stalk out of 8, 7 to costa out of 8, 9 absent. Hind wings a little o\er 'J/2. cilia 23-^; Ic faintly visible, 3 and 4 absent, 6 absent, 5 and 7 stalked from before middle, cell open between 2 and 5. Frenulum of many spines. (Fig. 23). Type: Obrussa ochriJascieUa Chambers (Can. Ent., V, 128, 1873.).' The genus seems to approach Ectcedemia Bsk. more closely than any of the other allied genera; from Ectcedemia it differs chiefly in the presence of vein 5 of the fore wings and in the position of the spurs of the hind tibiae, which are situated above instead of below the middle. Obrussa is relati\ely somewhat shorter and broader winged than either Ectademia or Nepticula. In describing Nepticula ochrifasciella, Chambers probably had before him males onl\-, which are uniformly smaller than females. and alone show the distinct ochreotis under surface of the basal.
