H. arnymai Dyar (40 i). Forewing on the yellowish-red ground marked with red-brown, in the central arnymai. 
area strewn with brown, with red-brown transverse lines, the anterior one forming 3 bows, the posterior one 
being finely dentate, between them a dark median shadow, the light maculae embedded in a darker ground; 
the marginal area is densely irrorated with red-brown. Hindwing reddish-brown. Mexico. 
116. Genus: Ithodoecia Hmps. 
Distinguished from the preceding genus chiefly by the presence of bent unguiform spines on the outside 
of the anterior tarsi; the only small species has a rounded apex of the forewing. 
R. aurantiago Gn. (= illiterata Grt., differta Morr., illinoisensis French) (40 i). Forewing purple red, aurantiago. 
in the central area orange, at the margin irrorated with black, with blackish transverse lines, the posterior 
line dentate, the maculae hardly noticeable. The $is more reddish-yellow with more distinct maculae. Hindwing 
on the yellowish ground irrorated with carmine. New York to Florida. 
117. Genus: Pyrrliia Hbn. 
The only species from North America and doubtfully reported from Brazil has been described in the 
Palearctic Part in Vol. Ill, p. 227. It differs from the other closely allied genera by the thorax being purely 
clad with hair, with an insignificant dorsal ridge. Cf. Vol. Ill, p. 227. 
P. umbra Hjn. (40 i). Together with this type the form exprimens Wkr. (= angulata Grt.) (40 k) umbra. 
occurs, in which the postmedian and marginal areas are densely irrorated with red-brown; it occurs in Canada exprimens. 
and the United States. — Whether cilisca Gn. which was described from Brazil and the type of which was in cilisca. 
Oberthur's collection, belongs to it, is still doubtful; it has lighter yellow hindwings and on the forewing a 
carmine post-median band. — ab. stilla Grt. (40 k) has orange-red forewings, without any marking in the basal stilla. 
area and without maculae, with an intense dark median shadow and bright red fringes. Western States: Colorado, 
Idaho, New Mexico. 
118. Genus: JErythroeela Hmps. 
Here the frons exhibits a rounded projection with a horny plate below it; the thorax is only clad with 
hair and has no tufts. The abdomen as usually exhibits a tuft only on the first ring. Some pretty yellow and 
pink species have been described. 
E. suavis Edw. (40 i) has yellow forewings with pink transverse bands and small maculae, as well suavis. 
as a red costal margin. The greenish fringes are at the end pink. Hindwing yellowish-white, in the apical marginal 
portion reddish-brown. Colorado, New Mexico. 
E. euposis Dyar (40 h) is larger than su-ivis, which is very similar, more intensely pink-spotted, with euposis. 
much larger maculae, in the central area likewise spots; the posterior line is composed of 3 rows of partly 
confluent spots, also the marginal spots are larger; hindwing black with a whitish margin and fringes. Mexico 
(Tehuacan). 
E. rhodophora Hmps. (42 i). Here the thorax is almost quite carmine, the rows of spots on the rhodopJwra. 
forewing are faded and flown together forming broad transverse bands, but the marginal spots very small. 
Hindwing yellowish, irrorated with blackish-brown, with red veins and margin. Expanse of wings: 34 mm. 
Guatemala. 
119. Genus: £mboloec!a Hmps. 
Separated from the preceding genus by a differently shaped frontal projection: a vertically placed 
flattened horny projection, in front rounded off. Thorax clad with hair and hairlike scales, in front there is 
a long tuft turned hindward, on the metathorax a parted tuft. The abdomen exhibits some small tufts 
on the first rings. The only species was described from California. 
E. sauzalitae Grt. (= erubescens Bsd.) (40 i). The yellow forewing is strewn with red-brown, before sauzaliiae. 
and behind the central area and in the cell irrorated with purple brown, the veins finely striped brown, with 
darker, somewhat faded transverse lines, the posterior line double; the coniform macula and ring-macula are 
white, the former bicuspid, parted by a yellow stripe, the latter small, centred with brown; the reniform macula 
is yellow, above with 2, below with 3 small white spots. Hindwing yellowish-white, irrorated with brown, with 
darker veins.
