166. Genus: IMagioimmiciis Grt. 
Separated from the preceding genus by more porrect palpi and the frontal appendage representing 
a large round projection provided with a ring-enclosure, with a horny plate below it; anterior tibiae short and 
broad, with a large bent claw-like spine at the end, inside and outside a smaller one. — Exclusively American. 
P. pityehromus Grt. (= media Morr.) (45 f) on the whole resembles P. tepperi, but it is of a more pilychro- 
reddish-brown tint and is distinguished by the presence of dark brown white-ringed maculae. Hindwing greyish- 
brown. From New York to Texas and Colorado. 
P. triplagiaius Sm. (45 f) is smaller than the preceding sjtecies, distinguished by hardly traceable iri-plagiatw 
maculae and a dark brown triangular spot between them; before the lower half of the undulate line there is a 
blackish-brown oblong wedge-shaped spot. Hindwing light brown, at the margin somewhat darker. Colorado. 
New Mexico, Arizona. 
P. laverna Drc. (45 g) is still smaller, darker brown, strewn with white, similarly marked, the maculae lavema. 
surrounded by white, the ground between them not darkened, behind the distal transverse line with a black 
triangular spot strewn with white. Hindwing dark red-brown. Mexico. 
P. expallidus Grt. (45 g) is a lighter yellowish-white species strewn with olive-brown, with indistinct expullidus. 
double transverse lines and a faded olive-brown discal shadow, instead of the maculae there are only dots in 
the cell; the feeble whitish undulate line is proximally shaded with brown; hindwing white, at the margin 
brownish. Montana, Colorado, Durango. 
167. Genus: ]5fodoa Sm. 
Distinguished from the allied genera by the absent proboscis, the very short erect palpi, the frons 
exhibiting a large round horny projection in the middle, with a truncated central appendage; the scaled thorax 
exhibits only behind a loose tuft, the abdomen shows one on the first ring; the anterior tarsi are short with 
very long claws. A number of partly rather dissimilar species have been described, all from America. 
N. plagiata Sm. (45 g) has red-brown forewings with a black spot behind the base of the hind-margin, plarjiata. 
a small oblong one instead of the coniform macula and a triangular one at the costal margin before the undulare 
line; the red-brown transverse lines are on the averted sides bordered with a lighter yellowish colour, the maculae 
are in feebly lighter rings. Hindwing whitish, towards the margin feebly tinted red-brown. Arizona. 
N. rivulosa Sm. is didl ochreous yellowish with fine, distinct, darker olive-brownish double transverse rivulosa. 
lines, the anterior line very sharply dentate; between the indistinctly marked maculae an intense median 
shadow extends; the light undulate line is proximally shaded with dark, behind it the marginal area is alternately 
striped dark and light. Hindwing whitish, at the margin darker. California, Arizona. 
N. pallens Tepper (= nesaea Sm.) (45 g) is a very plainly marked species, yellowish-white with pollens. 
a faded olive median band, the marginal area feebly tinted olive. Hindwing white, at the margin tinted olive. 
From Utah to California and Arizona. 
N. cordova Barnes (45 g), originally described as Xanthia, exhibits yellow forewings, in some places, cordova. 
particularly in the median area at the costal margin, powdered with brown, with fine darker transverse lines, 
the posterior line dentate and with yellow maculae in the yellow ground of the cell; the undulate line is marked 
by small darker internerval spots. Hindwing diaphanous yellowish-white, at the margin hardly darker. 
Arizona. 
N. alcandra Drc. (45 g) is somewhat similar, of a purer golden yellow, strewn with orange-red. the alcandra. 
basal part of the costal-margin and the cell powdered with purple red-brown, the veins striped red-brown, 
with red-brown transverse lines and very large maculae strewn with orange-red and surrounded with red- 
brown. Hind wing yellowish-white. Mexico. 
N. lamiota Dyar (45 g) is much smaller and more slender than alcandra, the basal half obliquely lamiola. 
cut off, more intensely darkened by red-brown, the distal half of the wing of a purer golden yellow, only at 
the margin darkened; the transverse lines are somewhat more dentate. Hindwing whitish with a brown marginal 
line. Mexico (Cuernavaca). 
N. beata Dyar (45 h). Forewing white, marbled and marked with dark coppery brown, the transverse beala. 
lines submedianly connected, the anterior line forming 3 large bows, the posterior line feebly double and with 
large maculae in double rings; the fine undulate line is dentate. Hindwing white with a brown marginal line. 
Mexico (Zacualpan).
