NO. 1203. NEW NOCTUID MOTHS— SMITH. 445 



ish terminal line, tending to become lunulate, followed by a yellow line 

 at base of fringes. The ordinary spots are practically obsolete, though 

 the reniform may be traced by a vaguely paler shading and an equally 

 vague, darker lunate mark. Secondaries smoky, a little paler at base, 

 veins and a discal lunule smoky. Beneath gray to smoky, powdery, 

 with or without a discal spot and outer line. 



Expanse, 33 to 37 mm. = 1.32 to 1.48 inches. 



Habitat. — Denver, Colorado, October 9; Salida, July 10 (Oslar);rort 

 Collins, Colorado (Gillette) ; Colorado (Bruce). 



Four specimens, all females and no two alike. It is indeed with 

 some hesitation that I have associated them all under one name, but 

 all agree in the practical absence of the ordinary spots, the dominant 

 median shade, and the generally sordid, obscure coloring. The differ- 

 ence lies in the range between a distinct blackish shade defining the 

 subterminal line, and its entire absence, the former being the type of 

 the species. The shading of the secondaries in one specimen is dis- 

 tinctly darker. It will require a series containing males to settle the 

 matter fully.

39. CARNEADES NOCTUIFORMIS, new species. 



Ground color a pale mouse gray, powdered with brown and blackish 

 scales. Head with a broad brown transverse Mne. Collar inferiorly 

 brown, surmounted by a black middle line, upper portion of the ground 

 color. Thoracic vestiture mixed scales and flattened hair, patagia 

 a little relieved, tuftings evident though not prominent. Basal line 

 geminate, brown, outwardly margined by a brown shading in the sub- 

 median interspace. Transverse anterior line geminate, lines almost 

 equally well defined, inwardly bent from costa to median vein and 

 touching the orbicular, outcurved in the submedian interspace and with 

 a long outcurve below vein 1 so that the margin is reached very close to 

 its middle. Transverse posterior line not very well defined, geminate on 

 the costa, but beyond that not well marked, even, outcurved over the 

 cell, very close to the reniform and a little drawn in below. Subterminal 

 line pale, irregular, not well marked, defined by a darkening of the ter- 

 minal space which leaves the apex free, and by a dusky j)recediug shade 

 which is best marked on the costa. A narrow, black, terminal line, fol- 

 lowed by a yellow line at the base of the fringes. Median shade darkens 

 the cell between the ordinary spots, then runs parallel with and rather 

 close to the transverse j)Osterior line, the space between becoming 

 brown shaded and darker than the rest of the wing. Claviform evident, 

 brown ringed, concolorous, moderate in size. Orbicular large, irregu- 

 larly oval, oblique, open to the costa, ourtlined by black scales, annulate 

 by a slightly paler ring, the center concolorous. Reniform large, broad, 

 kidney -shaped, extending well below the median vein, black ringed, 

 annulate by paler scales, center brown, with a yellowish median line.
