NOKIH AMKRrOAN LEPIDOPTKRA. 85 



I do not consider CoplcucuUia a very distinct genus ; but it is dis- 

 tinguishable by an obvious structural character, which becomes im- 

 portant where so great a uniformity exists in the species generally. 

 Besides the described species above mentioned, two new forms are 

 referable here. 



C'opiciiciilliit astigiua u. sp. (PI. iv, fig. 8)— Ground color ash-gray with 

 l)hvckish irrorations; head smoky brown. Ci»llar with a transverse black line, 

 above which is a sliglitly luteous shade, followed by a darker gray shade Hue 

 before tip. Thoracic disc scarcely dusky in the male, only slightly in the female. 

 Primaries with all the veins black marked. Internal margin blackish. A black 

 line from base through the submedian interspace, broadening to an oblique 

 streak above the anal angle. Blackish streaks are in the interspaces between 

 veins 4 and 5, 6 and 7, and 8 and 9. An interrupted, dusky, terminal line. 

 Fringes smoky, with a whitish interline. Secondaries smoky fuscous, paler and 

 semi-transpareut in the male, veins and "outer margins darker, fringes more 

 whitish. Beneath pale, even powdery gray. Expands 40 41 mm.; 1.59-1.63 

 inches. 



Hab. — Colorado, Bruce. 



In this species the ordinary spots and all the transverse niacula- 

 tion are wanting, and the black streak over the anal angle is the 

 only prominent feature in the wing. The antennte of the male are 

 entirely simple, while the front has a distinct truncated protuberance. 



Copiciiciilliu propiiiqusi n. sp. (PI. iv, fig. 11)— Ground color a bluish 

 ash-gray ; head darker, with black and blackish transverse lines. Collar with a 

 prominent black median line, above which is a faint luteous shade and between 

 this and the cip gray and blackish shades alternate. Thoracic disc only slightly 

 darker. Primaries with all the veins dusky. T. a. line single, smoky brown, 

 only a little outwardly bent between veins except beneath the internal, where 

 it forms a long outward tooth, tJie return line forming a prominent black streak 

 on the internal margin. T. p. line indicated on the costa and vaguely traceable 

 beyond, becoming prominent in the submedian interspace, where it forms a black 

 curved or crescent-shaped mark, beyond which a broad, oblique, angulated streak 

 extends to the outer margin. Clavifonn extending across the median space, 

 incompletely outlined, but sutl'used by a pale luteous shade, wliich makes it 

 prominent. Ordinary spots distinct. Orbicular round, black ringed, annulated 

 with luteous and gray centered. Eeniform moderate in size, broad, black-ringed, 

 incompletely annulate in luteous, centre smoky. An interrupted l)lack terminal 

 line. Two rather indefinite, oblique paler gray shades in the subtermiual space. 

 Secondaries in the male whitish, with smoky veins and*outer border, and whitish 

 fringes, in the female smoky, with darker veins and white fringes. Beneath 

 whitish, powdery, darker, more gray in the female. Expands 41.5-44 mm.; 

 l.(j()-1.76 inches. 



Hal. — Colorado; Bruce, Nos. 107 and 539, 1 ^ , 1 $ . 

 The anteniue of the male are simple, and in both .sexes the front 

 is rougheried ; in the female more j)rotuberant, almost tuberculate.
