40 REVISION OF GENUS CUCULLIA—SMITH. 
Cucullia montane Grt. 
1882 Grt., Can. Ent. xiv, 175 Cucullia. 
Head blackish gray, front with black and pale transverse lines; 
palpi paler in front. Collar inferiorly luteous shaded, else rather pale, 
ash gray, with several indistinctly marked transverse lines and a black 
tip. Patagiz pale gray with a few prominent black scales intermixed. 
Dorsum of thorax dark brown, as are also the distinct abdominal tufts. 
Primaries bluish ash gray with a broad costal region washed with yel- 
low-brown, darker in the median space. Base yellow, shading into the 
ground color half way to the t. a. line. TT. a. line in most cases distinet © 
through the dark costal space, traceable over the long median tooth and 
distinct again on the hind margin along which also a blackish gray — 
shade extends. T. p. line pale through the dark costal space, very faint 
or wanting through the center of the wing, distinct asa pale incurve ~ 
margined by blackish, in the submedian interspace; thence from vein — 
1 to internal margin, inwardly oblique. A dusky shade precedes the 
pale Junule, and a yellowish-brown shade extends beyond it tothe outer — 
margin, superiorly marked by a darker brown streak. A series of black, | 
terminal lunules. A more or less obvious series of brown interspaceal 
streaks along the course of the s. t. line. Fringes gray, cut with pale, — 
and with a pale line at base. Ordinary spots large, well defined, usu-  ~ 
ally paler, more yellow. Orbicular with two brown inner dots, one 
above the other, sometimes connected to form a central line. Reniform 
with four brown dots, sometimes partly connected; but usually distinct. — 
Secondaries whitish, subhyaline at base, with a narrow dark outer mar- 
gin, broader in the female. Veins darker marked. Beneath, prima- — 
ries blackish, secondaries white, the margins broadly blackish. : 
Expands, 47 to 50 millimetres=1.88 to 2 inches. 
HABiTat: Montana, Colorado. 
Ten specimens, all of them collected by Mr. Bruce, are before me, — 
five of them from the collection of the U. S. National Museum. They — 
are practically all alike, varying only a little in relative distinctness — 
of maculation. I have seen others, none offering distinctive features. 
Itis the most distinctly marked of the species. The pale ordinary 
Spots are prominent, and the yellow base of primaries is characteristic. 
The dark costal margin is powdery and the insect has a rough or 
“‘squammose” appearance. It is intermediate insome respects between 
postera and asteroides and, while most nearly related to the latter, is 
amply distinct from either. 
The harpes are only moderate in length, widening basally, the tip 
oblique, somewhat drawn out superiorly and inwardly spinulose. The 
clasper is short, stout, rather obtuse at tip, from a broad chitinous base — 
along inner margin, extending obliquely upward and forward, and not 
reaching beyond the upper margin. 3 
It seems to be common and is attracted to the electric lights.
