Moth , — Anterior iviug.s slaty gray, shaded Avith pale bait' along internal margin, ivith a 
chestnut-brown basal patch and some brown .streaks and s])ots in the terminal space; internal 
margin crested. Extreme base of the wing brownish; basal line distinct; subbasal space large, 
grayish at costa, rich chestnut-brown below the cubital vein, ]»ale bnif along the internal margin, 
which latter shade extends from base to internal angle, A very dark brown streak extends from 
the basal line to the transverse anterior line below the median vein, and a similar streak at internal 
margin. Transverse anterior line daik brown, grayish at costa, undulate, bordered anteriorly by 
a pale buff shade from below subcostal vein to internal margin. Me<liaii space widest at costa, 
narrow at internal margin, grayish, with an elongate pale discal spot with dark brown center. 
Transverse posterior line cinereous, indistinct, subdentate, continued. Terminal space with a 
series of rich chestnut-brown streaks between the veins ; two more, linear, near the aiiex. Posterior 
wings pale cinereous with two indistinct median bauds; anal angle touched with brownish. 
Tliorax and collar brownish; tegulje grayish; abdomen cinereous, slightly brownish above. Under 
surface of thorax and inside .of legs brownish; outside of legs and sides of thorax clothed with 
cinereous hairs. Expanse of wings, l.dO inches. (Grote.) 
Dr. Dyar writes me that he has seen Behr’s A. 2 )aclfwa, "^It is just like A, but 
darker, the thorax most black,^’ I have also seen a poor si)ecimen in Mr. DyaUs collection. It may 
he compared with Pheosui portlandUiy which I regard as a melanotic form of P. dhnidlata, I 
copy Behr’s description. 
Anterior wings; basal third brown, bordered by a darker line, preceded by a dilution; from these the anterior 
half ashy gray, the po.sterior half brown; the second lino convergent and almost touching the first line that borders 
the basal third of the wing, ^irecedod by a discal linear mark, which is followed by a diluted shade, ending with a 
well-darkened apical mark, divided by two nerves into three spots. Near the external margin a diluted fulvous 
shade. Hind wings grayish. 
Found in Placer County, Cal. 
The species is similar to N. siczac, but tlio thorax is darker than the anterior wings. 
Type in collection of the California Academy of Sciences. 
Larva. — Dr. Dyar has sent me the following description of the early larval stages from his 
notes: 
Stage I . — On hatching the larva runs to the apex of the leaf and sits with the anterior half of 
its body projecting. It eats the upper surffice of the leaf. Head round, pale brown; width, 5 
mm. Body shining, sordid greenish, a snbdorsal whitish line which becomes broken into oblique 
segmentary lines on the abdomen, a whitish lateral line. Segments (> and 12 slightly enlarged 
dur.sally. Thoracic feet and leg plates black. Cervical shield pale brown, tians verse. Tubercles 
distinct, black, normal i-v, vi absent, a long one on the leg plate. (It is structurally not different 
from Nerice in Stage I, and has the same habits. 
“ Stage IF . — Head high, narrowed toward the vertex, Battened before; smoky blackish mottled 
with pale in front in two ill-detined vertical bands. Body dark purplish with a blackish dorsal 
band and a pale shade on the side of the hump on abdominal segment 8 and slight jiale lateral 
oblicjue lines, 
and obscure. 
Prominence on abdominal segment 2 very slight. Thoracic feet black. Setoi short
