NEMORIA. By L. B. Prout. 
23 
of 9 palpus short. — ab. approximaria Pack, has the lines more approximated. —■ ab. latiaria Pack, lacks 
the proximal line of the hindwing. — Larva on oak, dead-leaf brown, its ragged appearance harmonizing well 
with the mutilated and partly withered leaves on which it rests. Head roughened, bilobed, the lobes slightly 
pointed; body granulated; abdomen with lateral processes on the first 5 abdominals, the first and last small, 
the middle 3 large, furcate, with the anterior limb the longer. The pupa hibernates. 
N. rubrifrontaria Pack. (= packardaria Grote) (3 d) is closely related to mimosaria (5 a), the 9 palpus at 
least as short, but has a reddish line on the vertex, some red admixture on the abdomen and on the fringes, 
etc. Eastern United States, fairly common. Recorded doubtfully from Utah by Pearsall. The larva is green, 
with small, bilobed, retractile head, rather small thoracic segments, abdomen with compressed lateral append¬ 
ages turned outwards and upwards, inclined considerably forwards and armed at the tip with 2 elliptical 
warts; these processes reach their maximum development on the 2nd segment and decrease to the 5th, and 
are reddish towards the end; segment 7 with subdorsal horns. Pupa grass-green, densely dotted with dark 
green; dorsal stripe black. 
N. albilineata Cassino (3 d). Wings slightly less broad than in the two preceding, more strongly strigu- 
latecl with white, the white lines broader, the white costal edge becoming rosy well before apex, the white 
fringes slightly flecked with pink opposite some of the veins. Abdomen from the 3rd tergite becoming reddish 
with whitish spots. Alpine, Texas. 
N. pistaciaria Pack. (= unistrigata Gmpbg.) (3 c). Brighter green, with very fine but dense white 
irroration, only the 2nd line developed. Both wings with a small cell-dot. Face bright red. Abdomen without 
dorsal spots. California and the Rocky Mountains. 
N. mutaticolor Prout is of a much bluer green, the cell-dots wanting, the line weak, the costal edge 
of the forewing not (as in pistaciaria) red beneath. Mexico: Sierra Madre, Topic. 
N. delicataria Dyar (4i). Slightly deeper green than pistaciaria, but not bluish, as in mutaticolor. Cell- 
dots wanting or faintly indicated in green. Very distinct in the bright rose-coloured fringes; parts of costal 
edge of forewing likewise pink. California. 
N. strigataria Grossb. Rather large, especially the 9- Pea-green, at least as profusely strigulated with 
white as in albilineata but with the lines indistinct; cell-dots present, though vague; termen and fringe much 
as in albilineata. Abdomen above uniform green, or only with white lines at posterior end of segments. Arizona. 
N. arizonaria Grote (3 b) is a more delicate, more whitish green species, with bright rosy costal edge 
and with the abdomen predominantly reddened above, dark-mixed. Arizona. 
N. olivearia Cassino is unknown to me, but I gather from the description that it is similar to the 
preceding, except that the red abdomen bears 3 white spots, the single line (the postmedian) is developed 
into a broader band, on the forewing running from 4 / 5 costa to near tornus, or the hindwing at %, parallel 
with distal margin, and the dark red terminal line, though delicate, is less rudimentary. Arizona: Para¬ 
dise, a pair. 
N. latirosaria Pearsall is another pale-green, semihyaline species, but more uniform. Wings relatively 
ample. Lines pale, on forewing two, on hindwing one; cell-marks linear, white, not distinct, that of the hind¬ 
wing as long as the cell-end, both lai’ger and more distinct beneath; costa of forewing above and beneath 
broadly rose-pink throughout, this colour at the base extending across the wing to hindmargin. Thorax and 
anterior half of abdomen above likewise rose-pink. Utah: Beaver Valley. 
N. zygotaria Hulst is unknown to me. “28 mm. Head ochreous in front, white on vertex. Wings, body 
and anterior part of abdomen deep peagreen. Costa narrowly white. Fringes green. Lines white, very like 
mimosaria (5 a), 2 on each wing. Beneath all wings lighter green.” Texas. 
N. oregonensis Cassino is very distinct in having the postmedian line of the forewing very little beyond 
the dark-green cell-dot, parallel with the termen and reaching the hindmargin only about 1 mm from the 
antemedian, while on the hindwing the two meet at costa so as to form a kind of curved V. Possibly, however, 
it will prove to be an extraordinary aberration of one of the adjacent species. 1st and 3rd tergites of abdomen 
each with a red, white-centred ring. Forewing with costal margin white, delicately tinged with red at base 
and apex. Fringes white. Oregon: Corvallis, 1 
N. darwiniata Dyar (3 c) somewhat resembles a large rubrifrontaria (3 d) with white, red-margined dorsal 
spots on segments 1, 3 and 4 of the abdomen. The very small red cell-dots are not always present. The fringe 
generally shows some slight pink marks at the ends of the veins. Founded on a series from Kootenai district, 
British Columbia. — californica (Tayl., MS.) subsp. nov. has larger cell-dots, suggesting a transition to the 
following species. San Diego, not rare, type in coll. Tring Mus. Dyar obtained eggs from Kaslo and reared
