of the is yellowish-brown, the anal wool of the $ white. Arizona, in August. 
L. pyrrha Dyar (18 k) is very similar, somewhat smaller, at the proximal margin almost purely pyrrha. 
white like the base of the fringes, the veins in the marginal area powdered with whitish like the costal margin; 
the ring-macula is a chestnut-recl circle, the median shade is blackish; the hindwing is somewhat lighter. From 
Mexico. — simplicifacta Dyar (18 k) is only a form without any white in the reniform macula which represents simplicifac 
an oblong, rust-brown streak; in transitions to this form there are white scales interspersed in the surroundings. 
24. Genus: Oialneata Wkr. 
Characterized by a somewhat keeled tuft on the prothorax, the short last joint of the palpi, a loose 
tuft only on the first abdominal ring, the thorax being only clad with hair and hair-like scales, and a smooth 
frons without any convexity. The genus contains very different insects, partly large tropical species with long- 
combed, serrate or plain antennae; the wings with a smooth or also notched distal margin.

Ch. elsinora Barnes (= erebus Sm.) (18 k). Forewing very dark blackish-brown, with a delicate elsinora. 
purple tinge and coal-black markings which, however, are little prominent on the dark ground; transverse 
lines dentate, in some places double, filled up with a somewhat lighter colour, between both a narrow median 
shade ending at the proximal margin near the anterior transverse line; coniform macula filled up with black, 
the ring-macula finely encircled with black, inside of which it is finely ringed yellowish, the reniform macula 
is bordered with black spots, in the distal half filled up with yellow, sometimes also in its whole width; undulate 
line formed of yellow scales mixed with black ones, with 2 black sagittae behind the cell, which extend to the 
reniform macula. Hindwing bordered with a broad blackish brownish-grey, towards the base lighter with a 
distinct discal spot. Arizona, Mexico. 
Ch. palmillo Barnes (181) is similar, but much lighter, forewing yellowish brown, darker, shaded palmillo. 
with purple, with rather indistinct transverse lines, the posterior line dentate, the undulate line only marked 
by a darkened area before it, the veins in the marginal area darkened; ring-macula finely encircled with dark, 
the reniform macula strangulated in the centre, in a dark ring, inside of which there is another concentric 
ring, the coniform macula being likewise encircled with dark. Hindwing light yellowish-white with somewhat 
darker fringes. South Arizona. 
Ch. signata Wkr. (= semiaperta Morr.) (181). Red-brown with darker striped veins and fine, undu- signaia. 
lately dentate, single transverse stripes; the upper maculae are surrounded with brown, the ring-macula is 
small, round, the reniform macula narrow, below often bordered with white and above spotted white, between 
them a dark median shade which is angular at the lower cell-angle; undulate line faded ochreous-yellowish, 
the marginal area behind it darker, the veins on it more or less dusted with whitish. Hindwing dark reddish- 
brown. From Canada to New Mexico. 
Ch. notata Streck. (= syrissa Streck.) (181). Forewing bright purple reddish-brown, strewn with noiata. 
white, with indistinct, finely dentate transverse lines and median lines; the coniform macula and ring-macula 
are absent, the reniform macula is white, in the centre and upper half tinted yellow, with 2 fine red-brow r n 
streaks on the discal fold, the surroundings somewhat darker, the undulate line only discernible owing to 
the darker defined marginal area. Hindwing dull yellowish-brown with more reddish fringes. United States 
(Illinois, Nebraska). 
Ch. baranea Barnes (18 1). Forewing reddish brownish-grey, more or less strewn with a lighter colour, baranea. 
particularly on the feebly darkened veins, the dentate single transverse lines rather inconspicuous, between 
them a somewhat stronger median shade, obliquely to the lower end of the reniform macula and from there 
to the centre of the proximal margin. Discal area and marginal area slightly darker, basal and costal areas 
somewhat more intensely strewn with light; coniform macula and ring-macula are quite faded encircled with 
a darker colour or entirely absent, the reniform macula is filled up with reddish and distally bordered by 4, 
proximally by 2 or 3 small white spots, the distal ones being much stronger, and the second from above twice 
as large as the others or also bipartite; the undulate line is somewhat darker than the ground. Hindwing brownish- 
grey, distally whitish. From Texas. 
Ch. fistula Harv. (= ulamora Sm.) (18 1) is somewhat similar, dull reddish-brown, dusted with grey, fistula. 
the latter particularly in the costal-marginal and proximal areas; transverse lines fine black and rather little 
prominent, the posterior line dentate; coniform macula and ring-macula likewise finely encircled with dark; 
reniform macula distally a white crescent of single small spots with one in front at the lower end. Undulate line 
brown with faint, small ochreous-yellowish spots; on the ends of the veins there are white dots. Hindwing 
whitish, dusted with brown in the marginal area, in the $ darker. Colorado and California.
