Sohinia biiiiKliilata n. sp. — Head white, with a faint olivaceous tinge, 
much more marked on the thorax ; abdomen fuscous. Primaries a faintly green 
luteous or olivaceous, the terminal space slightly paler, else almost uniform in 
tint. The median lines are very distinct, broad and white; the t. a. outwardly 
curved and inwardly marked by a few black scales ; t. p. S-shaped, or strongly 
hisinuate, outwardly relieved by a few black scales. Fringes whitish, uniform 
in color. Secondaries faintly olivaceous, pale, with an indefinite dark outer 
hand, and a dusky discal spot. Beneath, primaries silver-gray, with the costal 
and outer margin narrowly yellowish. Secondaries white, with a faint discal 
spot. Expands .92 inch. ; 23 mm. 
Hab . — Colorado (Bruce). 
This haudsoiiie and strongly marked species is allied in structural 
characters to trifascia or cumatiiis, and is very distinct from anything 
I have seen. 
The single specimen before me is from Mr. Nenmoegen’s collec- 
tion, and I do not remember having had others. 
Scliiiiia simple.^ n. sp. — Head, thorax and primaries of a glistening, pale 
green color; immaculate. Secondaries a very faint ocher yellow, with an in- 
definite dusky discal spot, and a dusky outer margin, not extending more than 
two-thirds from apex to anal angle. Beneath, a glistening, pale yellowish white, 
with an indefinite blackish discal spot on all wings. Expands 1.20 — 1.28 inch. ; 
30 — 32 ram. 
Hab. — Colorado. 
This species has a single long inner and three feebler outer, claw- 
like spines to the fore tibia, and it belongs to the series with trifascia 
and gracilenta, from all of which it differs in the immaculate prima- 
ries. The specimens were collected by Mr. Bruce, and are distributed 
in a number of collections, including that of the U. 8. Nat. Mus. 
The specimen before me is marked “ Denver, Light, July 21, 1887.” 
In the two specimens in the Museum collection, one, marked 
“ Foot-hills, Colo.” has entirely immaculate secondaries; the other 
specimen is much deeper in color throughout, and the marginal black 
band is much more distinct, and is complete, extending also along 
the costa. 
Scliiiiia ci'Oiiilinea. u. sp.— Head and thorax yellowish white, the thorax 
with an admixture of ouherous scales. Primaries whitish, with a strong ad 
mixture of ocherous, the maculation with a brown admixture to the ocher. A 
broad sub-basal, dusky band, outwardly limited by the white t. a. line, which is 
outwardly curved and irregularly denticulate on the veins, the widest outcurve 
in the submedian interspace. Inwardly this line is marked by a few black scales, 
outwardly it is indefinite. T. p. line white, outwardly defined by black scales, 
crenate, with distinct outward spurs on the veins, its general course feebly bi- 
sinuate. S. t. line marked by the difierence between the brownish s. t. space
