a large anal one enclosing the genitalia. The lateral tufts not promi- 

 nent. The anterior wings are dull gray, slightly tinged with yellow- 

 brown. The terminal, and upper part of the basal and. median spaces, 

 of a darker shade of the same color. The lines are all present, but 

 somewhat confused. An obscure basal streak beneath the median 

 nervure, and a similar one, slightly beyond the first, and not touching 

 the base, below the submedian. The interior line is oblique, removed 

 from the base, and thus narrowing the median space, blackish,, and 

 preceded by a clearer line of the ground color. To it are attached 

 the orbicular and claviform spots, the former rounded, the latter ob- 

 tusely triangular; both are concolorous, and faintly annulated with 

 black. The median and subcostal nervures are tinged with dull 

 black in the median space. Eeniform spot normally formed, with a 

 dark, internal shade line; in one specimen this spot is of the ground . 

 color, and therefore lighter and slightly contrasting with the median 

 space; in the other white, and very conspicuous. Exterior line 

 shortly denticulate, drawn in below the reniform spot, limiting the 

 dark median space. The wide subterminal space is of the ground 

 color, containing beyond the exterior line a double series of faint 

 black and white spots on the nervules. The subterminal line is con- 

 colorous, preceded by an undulating, dark, diffused shade, which sets 

 it off. The terminal space is very narrow, black, and having a pur- 

 ple reflection; in one specimen it is slightly frosted with whitish 

 scales. A series of light dots at the base of the dark fringe. Pos- 

 terior wings uniform dark fuscous, fringe lighter. Beneath, the 

 anterior wings are dark gray, the costa and terminal space lio-ht. 

 Posterior wings with a discal dot, and a median and subterminal line. 



Hab. Nebraska; New York. 



The two specimens before me of this species are variable. The 

 one from Nebraska, received through the kindness of Mr. G. M. 

 Dodge, I consider the typical form; in it the reniform spot is concol- 

 orous, and the white frosting of the terminal space is absent. 



In the other, from the Adirondack Mts., N. Y., collected by Mr. F. 

 C. Bowditch, the reniform is whitish and evident. I do not propose 

 a new name for this form in case it should prove to be distinct. 



Segetia fidicularia nov. sp. 



Expanse 30 mm. Length of body 1 2 mm. 



Eyes naked. The antennae are filiform. The front, collar and 

 thorax concolorous, rounded, and with smoothly stroked villosity. 

 The anterior wings are of a clear, light, uniform gray. The lines
