States to Ohio. — Larva black with a red dorsal line, numerous yellow longitudinal lines and a broad 
yellow lateral stripe divided on each ring into 4 spots by black vertical lines. 
C. oribac B. (25 k) resembles the preceding, but the maculae are altogether absent, the black proximal- oribac. 
marginal stripe is fainter, the small light postmedian luna at the proximal margin S-shaped and more oblique, 
the hindwing darker. Arizona. 
C. arizona Sm. (= strigata Schs., perstrigata Hmps.) (25 i) has generally darker bluish-grey forewings, arizona. 
particularly before the centre with a very distinct dark longitudinal stripe above the median, continued almost 
to the margin, the maculae marked by 2 or 3 thick black dots. The light brownish hindwing is darker on 
the margin and veins. The abdominal tufts are small and black. Arizona, Mexico. 
C. perlucida Jones is a very light species with a rounded apex. Eorewing yellowish-white, in the perlucida. 
submedian space almost transparent white, particularly at the costal and proximal margins dusted with brownish, 
with black, fine, strongly dentate transverse lines, without maculae; the proximal margin and distal margin 
are narrow blackish; the usual subanal black oblique stripe, before it from the centre of the proximal margin 
almost to the centre of the lower median branch there extends a faded black stripe. Hindwing white, veins 
and margin light brown. Expanse of wings: 45 mm. Described from Brazil: Castro (Parana). 
4. Genus: STycteropliaeta Sm. 
Distinguished from Cucullia by the thorax being only clad with hair, the abdomen being without any 
tuft, and a horny plate below the round frontal projection. The anterior tibiae exhibit at the ends inside a 
strong claw-like spine and outside a feebler one. Only 1 species: 
N. luna Morr. (= magdalena Hulst., notatella Grt.) (25 k) is a uni-coloured silvery white species, luna. 
only the abdomen is occasionally hued with brownish. The forewing exhibits single black dots in the cell, at 
the costal, proximal and distal margins. Widely distributed in the United States. 
5. Genus : Hmps. 
Distinguished by the thorax being chiefly covered with scales, the collar being only slightly hooded, 
the abdomen tuftless, and a triangular tuft on the metathorax. The frons exhibits a slight rounded projection, 
the tibiae are without claws. But 1 species: 
0. ocellata Wkr. (26 a) is a very easily recognized species not to be mixed up with any other owing ocellata. 
to its ochreous-whitish forewing with a grey proximal-marginal part and the large black ocellus-shaped spot 
at the anal angle. Only from Mexico. 
6. Genus: ItJsiagmssuIa Hmps. 
Distinguished from the preceding by a small horny plate below the frontal projection, the thorax being 
chiefly clad with hair, without a tuft on the metathorax. Abdomen likewise tuftless. Several African and 
eastern species. Only one American: 
E. argyrina Gn-. (26 a). Forewing reddish-brown, in the proximal part white with a silvery white argyrina. 
longitudinal band through the cell as far as into the apex. Hindwing white with a narrow brownish margin 
in both sexes. South Brazil, Argentina, Uruguay. -— The form pura Btlr. is also in the proximal part of the pura. 
forewing brownish, and the hindwing of the $ is cpiite brownish. From Chile. 
7. Genus: Callievg;t»s Hbn. 
Proboscis developed, the smooth frons exhibits 2 transverse fillets of hair; the thorax is clad with hair 
and hair-like scales; the collar shows a slight middle keel, the prothorax and metathorax loose tufts, the abdomen 
on the first rings large tufts. Beside the palaearctic C. ramosa (vol. Ill, t. 24 d) 2 South American species have 
been described: 
C. peruviana Hmps. Forewing bluish-grey, strewn with brown and black, the brown discal area peruviana. 
obliquely extending to the apex, with a black basal ray; the large coniform macula is encircled with black, 
the upper maculae grey, strewn with brown and encircled with black, except the upper end, behind them a 
dentate black transverse line; undulate line in the upper half marked by a dark shade, below it by an oblique 
black streak. Hindwing white, at the margin brownish with black veins and discal spot. Expanse of wings:
