are geminate, black, not well marked. Basal line geminate, fairly dis- 
tinet, a black, feebly marked basal dash. T. a. line upright, slightly 
lunulate. TT. p. line evenly bisinuate, followed by a series of white, — 
then of black, venular dots. A more or less evident median shade line. 
S. t. line whitish, nearly even, preceded by a series of lunate black 
marks. Veins black marked through terminal space. A fine black ter- 
minal line. Fringes finely cut with white. Claviform whitish, discol- 
orous, triangular, acute. Orbicular white marked, round or ovate, up- 
right. Reniform large, upright, more grayish, usually darker than 
orbicular. Secondaries dirty white, outwardly black powdered, form- 
_ ing a variably distinct submarginal band and blackish terminal line. 
Diseal spot of under side faintly visible. Beneath white, powdery, 
both wings with a more or less obvious dark outer line and discal spot.

This is a distinctly marked and easily recognizable form, differing 
by its dull, lusterless black appearance from all the other species. It 
was originally described by Mr. Grote from Prof. Fernald’s collection, 
and with this I identified specimens sent me by Mr. Bruce from Colo- 
rado. In the U.S. National Museum is a specimen sent by Mr. Hudson, 
from Plattsburg, N. Y., and Mrs. Slosson has sent me the species from 
Franconia, N. H., for determination. The distribution is therefore wide; 
but confined to high latitudes and mountainous regions. There is no 
apparent difference between the Colorado and New Hampshire speci- 
mens now before me. The sexual characters are somewhat like those 
of curialis in type. The harpes are narrowed beyond the middle, some 
what dilated again at tip which is inwardly fringed with spinules, and 
the superior angle of which is furnished with a thick, blunt, corneous 
spur. There are three corneous clasper processes. The first, at lower 
margin near base, short, broad, beak-like. The second at middle of 
upper margin, with a broad corneous base and a moderately slender, 
nearly straight process. The third arises from the middle of the harpe, 
nearer the tip, and is a long, curved hook extending nearly to the proc- 
ess at the upper angle of tip. 
The species seems by no means common, even where it occurs. I 
believe the specimens were all taken at light and, if I mistake not, 
quite early in the season.
