Among a collection of Lepidoptera made by Mr. Theo. L. 

 Mead in Colorado Territory, arc specimens of an undescribed 

 species of Anarta, which differs from all the American species 

 known to me in its more lengthy villosity, in its colore and 

 the greater proximity of the median lines on the primary 

 wing. I describe it as follows : 



Anarta nivaria, n. s. 



g. The eyes are hairy. Fore wings, thorax and head purple gray. 

 Median lines approximate, scalloped or dentate, blackish, obsoletely gem- 

 inate, accompanied by light gray shades. The narrow median space is 

 darkened by the passage of the broad diffuse blackish median shade. 

 Ordinary spots inconspicuous, the orbicular pale ringed, a little oblique 

 ovate; the reniform upright, narrowed, somewhat scroll-shaped, pale 

 ringed with a darker centre. The sub-basal space more blackish than the 

 basal and terminal spaces, the darker tint evenly spread and deepening to 

 the subterminal line, which is continuously indicated by the contrast of 

 color and of the usual irregular shape. Fringes not checkered, darker 

 than the wing. Hind wings yellowish fuscous, with discal lunule and 

 vague darker outer borders; an indistinct sub-continuous dark terminal 

 line; fringes pale, not checkered. Abdomen of the same hue, but a little 

 darker' than hind wings. Body short, villose. Beneath, both wings, 

 light yellowish, with distinct lunules and traces of a common fuscous 

 line. 



Expanse 28 mm. Two specimens varying in the distinctness of the 

 markings on the primaries and numbered 21 and 22. 



There is also in Mr. Mead's collection an interesting spec- 

 imen which I have considered as belonging to the Ileliothidce, 

 and as constituting the type of a distinct genus allied to 

 Anarta. The legs are spinose, and thus it has a strong fea- 

 ture in common with Agrotis. The naked eyes are, however, 

 encroached upon by the caputal tegument, somewhat sensi- 

 bly narrowed, ovate, lashed. The shape and vestiture of
