LEPIDOPTERA

Hadena tenera Smith. 



Professor Smith has prepared the following description of this new 

 form : 



Hadena tenera sp. nov. 



Ground color of head, thorax and primaries a rusty, red brown. 

 Collar a little darker, tipped with an indistinct, richer brown trans- 

 verse line. Patagia somewhat smoky shaded. Dorsal tuftings distinct, 

 rusty brown. Abdomen dull gray with distinct, rusty-brown dorsal 

 tufts, and rusty, fine hair. Primaries with a narrow, black basal streak 

 and a short black streak along the inner margin at the inner angle. 

 Basal half line black, broken, geminate, included space more yellow- 

 ish. Transverse anterior line geminate, black, even, inner portion 

 partly lost ; as a whole with a very even, not greatly marked outcurve. 

 Transverse posterior line geminate on the costa, outer portion lost, 

 inner narrow, black, lunulate, followed by a somewhat more yellow 

 shading, only a little incurved below the cell. Subterminal line yel- 

 lowish, somewhat diffuse, forming a small W on veins 3 and 4. A 

 series of small, terminal lunules. Claviform moderate, concolorous, 

 incompletely black margined, a black line extending from its tip to the 

 transverse posterior line. Orbicular ovate, oblique, irregular, a little 

 paler than the ground color. Reniform large broadly kidney-shaped, 

 partly annulate in yellowish, inwardly margined with black scales. 

 Secondaries whitish at base, shading to smoky, with an obscure, 

 smoky, extra median line and a small discal spot. Beneath powdery 

 reddish gray, with a powdery outer line and discal lunule ; disc of 

 primaries a little darker. 



Expands 36 mm. = 1.44 inches. 



Habitat. — Kukak Bay, Alaska, July 4, 1899. 



One male in fair condition, save that the primaries are rubbed at the 

 outer margin and have lost the fringes. The antenna are distinctly 

 serrate and the processes bristle tufted. The species is allied to and 

 somewhat resembles a small barnsii. The thoracic vestiture is more 

 dense than usual and somewhat loose, perhaps as a defect. 



Type. — Cat. no. 4844, U. S. National Museum. 



Hyppa rectilinea Esp. 



Hyppa rectilinea Esp., Schmett. Abd. Nat., i, 127, 1777. 



Six examples : Kukak Ba}', July 4. 



Seems to correspond with the European species rather than with the 

 eastern xylinoides Guen. or the western indistincta Smith. 



Pachnobia carnea Thunb. 



Pachnobia carnea Thunb., Mus. Nat. Ac. Ups. Diss., 4, 56, 72, f. i, 1788. 



Thirty-eight examples : Popof Island, July 10-15 '■> Kukak Bay, 

 July 4; Unga Island, July 21.
