line, arcuated superiorly to third median nervule. Subterminal space 

 clear bluish-grey, Costa blackish with four white pre-apical dots, the 

 first of which surmounts the reniform spot. Subterminal line yellow- 

 ish-grey, preceded by olivaceous scales. Terminal space pale bluish- 

 grey, discolored by brownish scales above the internal angle, and again 

 at about first median nervule below the apex. Fringes grey irregularly 

 sprinkled with darker scales at the extremity of the interspaces. 



Posterior wings very pale whitish-grey, with two terminal parallel 

 darker shade bands, of which the inner is sub-obsolete. A narrow ter- 

 minal black line discontinued before anal angle. Fringes whitish. 



Under surface very pale greyish, shaded with vinous or violaceous 

 scales. Anterior wings with grey scales along the costa. Two subter- 

 minal vinous shade bands, which are continued on the secondaries to 

 before the anal angle. The posterior wings are whitish, sprinkled with 

 vinous scales along the costa. 



Head and thorax clothed with grey scales; on the tegular these are 

 whitish with a faint internal line. Disc of the thorax with a few oliva- 

 ceous brown scales, which form the central thoracic tuft. Meta-thoracic 

 tuft formed of whitish scales. Abdomen whitish-grey, darker beneath, 

 with two dorsal brown tufts on the third and fourth segments above. 

 Legs and under-thoracic parts grey ; tarsi anuulated ; posterior and 

 middle tibiae with whitish scales on their inner surface. 



Exp. % 1.30 inch. Length of body 0.70 inch. 



Habitat. — Rhode Island. (Mrs. S. W. Bridgham.) 



Several coincident specimens examiued. Allied to Mamestra arctica, 

 Boisd. (Hadena amputatrix, Fitch), but a much smaller and paler 

 species. The whitish body and posterior wings, the olivaceous scales 

 on the median space of the anterior wings, are features which will rea- 

 dily distinguish the present species from its congener. 



Respectfully dedicated to Mrs. S. W. Bridgham, whose collection of 

 North American Lepidoptera contains many rarities, owing to the 

 praiseworthy zeal displayed in augmenting it. 



XYLOPHASIA, Stephens. 

 Xylophasia vulgaris, sp. nov. (Plate ?>, fig. 2, % .) 



Dull brown. Transverse lines broken; nervules clothed with unin- 

 terrupted darker scales. A narrow basal sub-median dark streak. 

 Transverse anterior line geminate, acutely dentate; below the internal 

 nervure the inner line is broadly marked, running back nearly to the 

 base of the wing. Costally the wing is brighter colored. Reniform 

 and orbicular spots underneath, encircled by brown anuuli more or less
