Pennsylvania; 
Agrotis pitychrous, Grote, Plate 2, fig. 11, 4. 
Allied to Agrotis quadridentata and Agrotis cicatricosa (7. & R., from Colorado 
Territory and to the Russian A, acuminifera Hversmann, as figured by Herrich- 
Schaeffer, 
Pale grayish white from the base along costal region to the transverse pos- 
terior line which is indicated by dark dots. The costal edge is marked, show- 
ing the inception of the transverse lines which are not perceptible. The 
orbicular and reniform are rather large, grayish white, with more or less com- 
plete black annuli, lying on the dusky discal field that, in the male, shows 
a testaceous tint. The claviform mark is black and perceivable in its usual 
place without the transverse anterior line, the latter fragmentary. The 
extra basal line is geminate, even, and only. discontinued at the whitish costal 
shade, Median vein whitish and the whitish scales extend along veins three and 
four to the subterminal line which is exerted at this place. Subterminal space 
whitish, showing black, more or less evident, cuneiform marks before the line. 
‘Terminal space dusky, constricted medially owing to the exserted portion of the 
subterminal line, Interspaceal blackish cuneiform marks take the place of 
the terminal line. Fringes stained with testaceous. The hind wings are 
whitish with diffuse dusky borders in the male, while in the opposite sex they 
are nearly wholly blackish, contrasting with the white fringes and offering a 
distinetional character when compared with allied species ; a faint discal liture 
in both sexes. Beneath whitish, with dusky shadings ; no transverse lines in 
either sex ; a series of interrupted interspaceal terminal dusky marks. Cor- 
poral pubescence whitish ; collar with distinct dark lines which define also the 
tegulae, Abdomen whitish, stained with testaceous at the extremity ; ovi- 
positor exserted in the female in which the antennae are simple, while these 
are finely pectinate in the male, 
Lxpanse, 80 m, m. LHabitat, Long Island, N. Y. (coll. J. A.

13 Acronycta insolita, nr. 8., ¢, resembles A, Oblinita, in the lanceolate primary wings, which 
are even longer and more produced apically. Blackish; orbits of the eyes white. Primaries 
uniformly blackish, the dark tone obscuring all ornamentation except the t. p. and s. t. lines, 
which are oblique and appear as rather broad interspaceal lunulated or squared gray marks, 
which, in the as usual flexed t. p. line, are marked by black outward points, the fragments of the 
t. p. line itself, the gray marks being the preceding shade. Hind wings white beneath, with the 
costal region dusted with blackish scales. Palpi with the second joint outwardly black; fore 
tibiae with blackish longer hair, Abdomen whitish above, darker beneath, rather long. The 
unusually dark color and pointed wings, together with the peculiar appearance of the trans- 
verse lines, should make this species very recognizable, This last section of the genus reminds 
us of Leucania, My specimen of A, jnsolita, expands 1.60 inch, Coll, Am. Ent. Soe,
