near the base. Beyond the outer line are two spherical spaces with black 

 borders, and at the lower corner of the outer margin is a grayish patch 

 continued on the hind margin and bordered on the inside by an irregular 

 black line which runs up to the upper margin of the wing. Posterior 

 wings dark gray with a darker wavy line and discal spot more apparent on 

 the under surface. Head and tegulae brownish-black; thorax light and body 

 dark gray, latter with a row of brownish tufts on the upper surface. 

 Exp. If inches. 



Obs. A critical comparison of this species, taken in the vicinity of 

 New York, with specimens of the European D. pinastri has perfectly sat- 

 isfied me of their specific identity. 



Gen. HELIOTHIS Ochs. 



Antenn£B simple, threadlike. Palpi as long as the head, inclined up- 

 wards, third article minute. Anterior wings inconspicuously marked; pos- 

 terior pair with a dark band on the outer margin. 



H. umbrosus nov. sp. 



Anterior wings yellowish-gray crossed by several indistinct irregular 

 darker shaded lines. Discal spot blackish beyond which is a row of mi- 

 nute black dots one on each nervule running parallel with the outer mar- 

 gin of the wing and connected with each other by a faint waved line the 

 curvatures turned inward toward the base of the wing ; fringes dark. Pos- 

 terior wings yellowish-white without markings except a broad blackish 

 band running parallel with the outer margin and which is partly interrupt- 

 ed near the centre by a space of a similar color to the rest of the wing; 

 fringes white. Under surface of the wings pale showing the black discal 

 spot on the anterior wings plainly, outside of which is a blackish trans- 

 verse band and a small blackish streak near the upper margin. Under 

 surface of posterior wings immaculate except a faint blackish shade near 

 the outer margin. Head, thorax and tegulse yellowish-gray, darker than 

 the anterior wings. Body grayish, clothed at the sides with whitish hairs, 

 and darkening towards the tip. Exp. I2 inches. 



A male; taken on Long Island, N. Y. 



Ohs. Approaches to the European H. armigera which species has 

 however a discal mark on the posterior wings and is otherwise specifically 

 distinct. It appears also from the description of H. exjn'imcns Walker, (I. 

 B. M. Noctw p. 687, to have some resemblance with that species, but the 

 expressions " (alae anticse) orbiculari et reniformi magnis ferrugineo mar- 

 ginatis" and " (alae posticcie) Jitura discali" do not apply to the species 

 I have just described.
