Ch. palliatricula Gn. (35 li) is a variable, well-known North American species with greyish-brown. palliatrha- 
black-strewn forewings, the transverse lines above the submedian fold connected by a white stripe, the large 
brownish maculae surrounded by black. — In the typical form the maculae and the disc are white, in the form 
iaspis Gn. (35 h) irrorated with brown. • — - From Canada and the United States. iaspis. 
Ch. sensilis Grt. (35 i) has grey forewings which are more or less suffused with red-brown, with black sensilP. 
transverse lines bordered with grey, the maculae surrounded with black, centred somewhat reddish, and with 
a white strigiform spot from the end of the coniform macula to the posterior transverse line; the undulate line 
is proximally bordered with a faded brown. Hindwing brownish-grey. — In ab. subniediana Strd. (= ab .submediana. 
1 . Hmps.) the white submedian strigiform spot is absent. -— In the form niacdonaldi Benj. the black stripe is macdonaldi. 
absent, and the white colour expands over the median area. Described from New Jersey. •— United States 
(Massachusetts, New York, New Jersey). 
Ch. parviniacula Sm. (35 i) is somewhat similar, smaller, in the basal area and the proximal half oi parvimacu- 
the median area much darker, the transverse lines bordered with whitish, from the end of the greenish coniform 
macula a black stripe , above it a white stripe to the posterior transverse line; the light undulate line is on 
both sides bordered with greenish. Hindwing greyish-brown with lighter fringe. California. 
Ch. laticlava Sm. (35 i), according to Benjamin, has an exterior quite similar to Trachea divesta lath-lava. 
and may be synonymous; it is lighter grey than the two preceding species, in the median area as far as above 
the submedian fold brown with blackish transverse lines, the posterior line filled up with whitish; from the 
short and broad coniform macula a black stripe extends to the posterior transverse line, the large upper light 
maculae are surrounded with blackish; behind the light undulate line there are on the folds brown triangular 
spots. Hindwing light brown with a darker postmedian line. Washington. 
Ch. bogotica Wlcr. (35 i) is a smaller species with greyish-brown, black-strewn forewings, with double bogolica. 
transverse lines filled up with whitish, the whitish upper maculae surrounded with black and centred with 
brown, between and before them the cell is darkened by black; at the end of the coniform macula there is a 
minute white dot; the apex is parted by a light diffuse spot. Hindwing light brown, at the margin somewhat 
darker. Colombia (Bogota). 
Ch. poliosema Dgn. is still much smaller, the body is yellowish-grey, the forewing covered with blackish- poliosema. 
grey feathery scales, with 2 black single transverse lines, the posterior line in the shape of an angle with the 
apex near the anal angle; in the basal area some white irroration; no maculae. Hindwing yellowish-white with 
a darker postmedian line and marginal shading. Argentina. 
40. Genus: Oiytonidia Schs. 
Very closely allied to the preceding from which it is separated by exhibiting but one tuft on the first 
abdominal ring; besides, according to the original diagnose, the forewing lacks the areola and the prothorax 
is without the loose tuft, the spurs being shorter. Only 1 species. 
Ch. chloristis Schs. (35 i). Forewing lilac-brown, basal area, hind-margin, a spot behind the ring- chloristis. 
macula, the reniform macula and the undulate line are green, a large apical spot whitish-green, with fine black 
transverse lines, the posterior line dentate, behind it black and white vein-dots, before the anterior line likewise 
a white, submedian dot. Hindwing greyish-brown with pinkish-brown fringe. French Guiana. 
41. Genus: S*a i*al»r t v opii i I a Dyar. 
Proboscis feeble, frons with a rounded projection; thorax almost entirely clad with scales, the prothorax 
with a parted, the metathorax with a plain loose tuft, the abdomen with small tufts on the first and fourth 
rings. Only 1 species: 
P. edobasis Dyar (35 k). Forewing violet purple, in the median area grey, at the base of the hind- cdobasis. 
margin, at the apex and anal angle spotted light yellow, in the basal area and subterminally reddish. Transverse 
lines feebly lighter, the proximal line double; the small ring-macula in a light ring, the reniform macula is 
large, irrorated with white, centred with reddish. Hindwing white with a small discal spot and darker shading 
at the apex and anal angle. Mexico. 
42. Genus: Xeophaenls Hmps. 
Also exteriorly similar to the palearctic genus Polyphaenis. Proboscis developed, the frontal hairs 
produced into a small tip; thorax covered with broad flat scales, without any tufts; structure slender, the middle 
and posterior tibiae with smooth scales; abdomen with small tufts on the first rings.
