fairly outlined in the specimens before me, somewhat paler, but not 
white asin letifica. Ordinary spots vague, only the inferior margin 
of reniform at all distinct. Secondaries white basally with a rather 
indefinite dark outer border, much broader in the female. Beneath, 
primaries smoky in the ¢, blackishin the 2. Secondaries white, with 
a few marginal powderings in the male, with broad outer borders and 
dark powderings in disk in the female. 
Expands 48 to 52 millimetres=1.92 to 2.08 inches. 
HapiraT: New York, Albany June 6, Sharon Springs August 15; 
' Nebraska, West Point in May; Canada to Pennsylvania, west to Ne- 
braska. 
This species is easily separated from letifica by the darker color of 
primaries as well as the course of the t. p. line, to which attention has 
been already called. There is also aseries of fairly distinet interspaceal 
pale streaks extending in from the terminal space, which is not found 
in letifica. 
The harpes of the male are quite long, nearly parallel to tip; the 
latter is obliquely and acutely drawn out at upper angle, rounded at 
the inferior; its inner margin is spinulated as usual. The clasper is 
' quite long, slender, acuteiy pointed, curved, and exceeds the margin of 
 harpe. 
This species seems not common and there are not many in collections. 
The specimens before me are from the collection of the U.S. National 
Museum. 
Cucullia dorsalis sp. nov. 
Head ash-gray, with darker and paler lines on front. Collar bluish- 
gray, with a black basal, and double brown median transverse lines. 
_ Patagiz and dorsum gray, concolorous, dorsal tufts of abdomen incon- 
spicuous, gray. Primaries a rather deep bluish-gray, without any fus- 
cous admixture or shade; but with rather distinct black powdering. 
T. a. line much as in speyeri, but much more broken and less obvious. 
‘7. p. line evident only in submedian interspace, and there indistinct and 
broken, in course as in speyeri. The usual black streak below vein 2 is 
x distinct, and above it, in the two following interspaces, are small sagit- 
tate black dashes, all that remains of the terminal line. Fringes gray, 
- with a very narrow basal line. Claviform quite distinctly outlined by 
|. black seales, concolorous. Ordinary spots obsolete, save for a curved 
| black line that may indicate the inferior margin of the reniform. Sec- 
ondaries white at base, with a narrow and rather well-defined dusky 
/ outer border. Beneath primaries smoky, secondaries white, outer 
borders blackisb. 
Expands 46 to 50 millimetres=1.84 to 2 inches. 
HABITAT: Colorado (Bruce). 
Two females are before me, and compared with the same sex of 
| speyert they are purer blue-gray, lacking all trace of the fuscous shad- 
ing. The markings are more powdery, black, and yet less complete.
