Ciii'iiesMleM f'lii^iiiiaciila n. sp. — Head and thorax mouse-gray, collar with 
a blackish central line. Primaries dull red-brown, subcostal and median vein 
white i)owdered. Basal line geminate, well defined, included space with white 
powderings. T. a. line geminate, interrupted below costa, a long inward angle 
on cell, then evenly oblique outwardly to hind margin. Below the median vein 
the defining lines are well written, the included space concolorous. T. p. line 
even, outcurved over cell, thence parallel with outer margin. The inner de- 
fining line is a series of blackish lunules, the outer a vague, diffn.se line, the in- 
cluded space very slightly paler than ground color. S. t. line marked only by 
the slight difference in shade between s. t. and terminal spaces; an interrupted, 
sublimate terminal black line, followed by a narrow yellow line at base of fringes. 
Apical spot powdered by a few white scales; a black basal dash below median 
vein, joining to the moderate, black margined claviform. A black filling to the 
cell before orbicular, and between the ordinary spots. The latter are fused, the 
orbicular oblong, oblique, merging interiorly into the reniform, which is some- 
what extended outwardly from its lower angle. The combined spot narrowly 
black ringed with a white interior line and a few white scales relieving the other- 
wise concolorous spots. Secondaries even, smoky fuscous, with paler, interlined 
fringes. Beneath smoky fuscous, powdery, with an incomplete outer line and 
somewhat indefinite discal lunule. Expands 1.28 inches; 32 mm. 
Hab. — California. 
A single male specimen iti good condition. The characters of the 
tessellata group are well marked, and the sjtecies is intertuediate 
between divergens and redhnicula, differing amply from both in the 
fused ordinary spots. The white marked veins are like divergens, 
while the s. t. line is like redimieula. The male characters agree 
with those of the allied species, and figure 64 of my Revision of 
Agrotis will answer for this species equally well. 
I*erig<*a piilveriileiita n. sp.— fTi-ound color a vague, powdery reddish 
gray, varying in tint according to the relative ju-edominence of red, white, or 
blackish scales. All the noiinal maculation present, hut obscured by the pow- 
dery ba.se. Basal line geminate, concolorous, defining lines fuscous or blackish, 
twice augulated. T. a. line somewhat paler, with fuscous or black defining 
lines, not always complete and sometimes vague; outwardly oblique, somewhat 
curved, inwardly angulate on the median and submedian veins. T. p. line ob- 
soletely geminate, the inner line lunulate, the outer vague and even, sometimes 
wanting, its course evenly bisinuate without the usual long outcurve from the 
costa over reniform. S. t. space palei- than median and usually also than terminal 
space; s. t. line pale, diffuse, sinuate, marked by the difierence in shade between 
s. t. and terminal space, and also djy a more or less obvious preceding shade, 
h'ringes interlined with fuscou.s, feebly scalloped: median space, as a whole, 
somewhat darker than the rest of the wing; a dusky or blackish median shade 
which in the submedian interspace sometimes forms a complete connection be- 
tween the median lines. Claviform small, though quite wide, concolorous, in- 
completely outlined in black. Orbicular round or oval, oblique, pale ringed with 
dusky centre. Reniform uiiright, quite large, somewhat constricted centrally, 
pale ringed with concolorous or paler center. A dusky costal iritch in the s. t.
