22. Genus: Pseudauarta GVi. 
Smaller-sized species the general characters of which entirely correspond with the preceding genera; 
palpi somewhat more erect, head and thorax clad with coarse loose scales, in front and behind with loose tufts, 
the abdomen exhibits quite a number of tufts. The apex of the forewing is sharper and more produced than 
in other genera. The species hitherto known are distributed from Canada to Mexico. 
P. flava Grt. (- dupla Sm.) (27 cl) has dark brown forewings strewn with grey, with a more reddish-brown 
area in the disc, double transverse lines filled up with whitish and submedianly connected by a black streak, 
with small rather indistinct maculae; the whitish undulate line, proximally shaded with red-brown, is situate 
near the posterior transverse line. Hindwing orange with a black marginal band. Canada to California. 
P. crocea Echo. (27 d) has broader wings, of a greyer colour, with more distinctly white-ringed maculae, 
a much narrower central area, the posterior transverse line therefore far remote from the undulate line. Hindwing 
yellow with a very broad black marginal band. Oregon, Colorado, Arizona, New Mexico. 
P. actura Sm. (27 d) is the smallest and darkest species. Forewing deep blackish-brown, with quite 
indistinct markings, only a white spot above the anal angle being prominent; both transverse lines double, 
somewhat more filled up with grey; subterminal area likewise somewhat lighter grey warming into the white 
anal spot. Hindwing light yellow with a broad black margin. New Mexico, Arizona. 
P. caeca Dod. (— crocea Hmps.) is very similar to flava (27 d), but it lacks the black basal ray, the 
posterior transverse line is more uniform and less bent, just like the marginal line; the subterminal area is broader; 
most easily dicernible by the light ochreous stripe above the black streak connecting the transverse lines; the 
upper half of the central area is ochreous, in flava reddish-brown; the filling of the double posterior transverse 
line is not white, only submedianly; the wings are shorter with an obtuser apex. Utah. Oregon. 
P. singula Grt. (27 d). Forewing more brownish-grey, in the disc brown with a black basal ray. double 
transverse lines filled up with grey, submedianly connected by black; the grey maculae are brown-centred 
and encircled by black; before the grey undulate line brown shading and small black sagittae behind it. Hindwing 
orange with a black marginal band. Texas, Colorado, Arizona. 
P. flavidens Grt. (27 d) is larger on an average, without the black streak connecting the transverse 
lines. Forewing reddish greyish-brown, in the central area darker, the anterior line is indistinctly double, the 
posterior line single, distally edged with whitish, the maculae are small, in whitish rings; the undulate line 
as in the preceding, behind it with darker striped veins of the marginal area. Colorado, New Mexico. 
P. heterochroa Dyar (27 d) is an extremely variable, variegated, small insect. Forewing on the whitish 
ground olive-greenish mixed with brick-red, the veins striped whitish, and similar transverse lines; the whitish, 
strongly dentate ixndulate line extends into the apex and is proximally bordered with blackish, the dark marginal 
line is traversed by whitish. Hindwing orange with a very broad black marginal band. From Mexico. 
23. Genus; Hoinoaiiarta B.-Bak. 
This genus was recently detached from the preceding, most closely allied genera; it is distinguished 
by the still more pointed apex of the forewing with a slight convave excision below it and a very convex centre 
of the distal margin. The thorax is almost entirely clad with narrow hair-scales intermixed with single hairs; 
the prothorax exhibits a hooded or almost pencil-shaped, often double-slashed, high tuft being continued in 
a keel-like shape to the metathorax, where it ends in a loose tuft. Some small Mexican species have been described, 
two of which proceed as far as North America. 
H. falcata Neum. (27 d) is on its dark brown forewing scantily strewn with white, with whitish veins 
particularly in the somewhat lighter subterminal area; transverse lines indistinct, on the averted sides bordered 
with whitish, the narrow oblique maculae in whitish rings; undulate line and a marginal line very finely whitish. 
Hindwing orange with a broad black margin. Texas, Arizona, and Mexico (City). •— Whether oblimata form nov. 
(27 e), from Tehuacan (Puebla), belongs as a form to it, is questionable; it is at once discernible by the broader 
marginal band of the hindwing not being jet-black but dark greyish-brown, and the orange basal half being 
darkened by brown scales and much more subdued; the forewing is also of a more subdued greyish-brown, the 
marking otherwise very similar, the light subterminal band extending into the apex is very prominent. 
H. senescens Dyar (27 e) has brown forewings with slightly darker basal and marginal areas, very 
fine transverse lines represented by white scales, large maculae, a round ring-macula, a distally concave reniform 
macula of the ground-colour, very finely surrounded with white, behind the distal transverse line in the somewhat 
lighter subterminal area black vein-streaks interrupted by white dots; the undulate line consists of small white 
internerval spots, behind it there is a marginal line being only on the veins spotted white. The brown hindwing 
is somewhat lighter ochreous towards the base. Mexico (Tehuacan, Zacualpan).
