yellow, the rest of the body inclusive of the palpi, collar and shoulder-covers bluish-black. Forewings black 
with a bronze-green lustre, hindwings with a dull blue shine. Expanse of wings: 48 to 52 mm. From Mexico 
to Guatemala. 
66. Genus: Pygoctenuelia Grt. 
Proboscis well developed; palpi rather long, beneath hairy, protruding forward; 3 antennae with short 
double combs. Anterior body and base of abdomen roughly haired. The $ has dense, woolly hair on the anus. 
Veins of the foreAvings as in Nyctosia, but with an accessory cell. On the hindwing, in enna, the lower radial 
veins and the upper one are petioled with the subcostal, in the other species not. — 5 species known hitherto. 
P. enna Drc. (35 m) has a black body with orange forehead, palpal base, collar, and shoulder- enna.

Forewings black with a bronze-green shine. Hindwings hyaline diaphanous with a broad, blackish-green border. 
Expanse of wings: 40 mm. Mexico. 
P. azteca Schs. is smaller and distinguishable by black, not red forehips. The collar, shoulders, aztecu. 
anal tuft, and a small spot at the base of the costal margin on the foreAving are in the 3 carmine, in the $ 
orange. Fringes in the 3 Avhite. Expanse of Avings: 38 mm. Mexico. 
P. terminalis Wkr. ( = pyrrhoura Hulst., votiva Ediv., bolteri Ediv., harrisii Bsd.) (35 m) is a well ierminalis. 
known, common species, on the body black with a metallic blue lustre, and scarlet forehips, collar, shoulders, 
and anal tuft; the latter is in the $ whitish at its extreme end. Forewings black with a green lustre and white 
fringes; hindwings more bluish lustrous. Expanse of Avings: 46 mm. Mexico, common. 
P. funerea Grt. (35 1) is a minute, dull black animal, Avith a very faint blue reflection; lateral spots funerea. 
on the collar, and the abdominal end are yellow. Expanse of wings: 28 mm. United States, Mexico. 
P. clita Drc. (35 m) is an entirely different, unicolorously orange-yellow species with longer palpi, clita. 
much more slenderly built, the Avings broader, with a narrow accessory cell. Palpal ends and antennae are 
black. Costa Rica. 
67. Genus: l*ron©la Hmps. 
Proboscis well developed; palpi erect, not reaching the vertex; 3 antennae ciliated; tibiae with long spurs. 
ForeAvings short and broad, with a strongly curved costal margin. The loAver median vein is strongly curved 
at its rise, the upper one rises before the cell-angle, from which the two loAver radial veins rise; the upper 
one rises below the upper cell-angle, the 4 lower subcostal veins petioled, only the uppermost separately 
from the cell. On the hindwing the upper median anastomoses with the lower radial vein; the middle 
radial rises above the lower cell-angle, the upper one anastomoses with the subcostal. The 3 exhibits beneath 
in the cell-end and on the lower median vein long scent-hair and above a scent-spot in the cell-end of the hind- 
Aving. 5 species are described. 
P. magniplaga Schs. (32 h). Head and thorax orange-yellow, abdomen reddish-brown. Forewings magni- 
pinkish-brown with a yelloAv base, costal margin and border. Hindwing light red-brown, in the costal half plaga. 
light yellow, in the $ darker. In the latter the apex is broader yelloAv. Expanse of wings: 20 mm. Brazil, Bolivia. 
P. fraterna Schs. is very similar, smaller, and the reddish-brown parts of the preceding are here fraterna. 
violettish-black. Expanse of Avings: 16 mm. French Guiana (Maroni River). 
P. diffusa Schs. (32 h) is likeAvise similar, paler yelloAvish, the greyish-brown inner-marginal area is diffusa. 
in the cell deeply incised by the yellow costal margin and has a yelloAv middle-spot. Hindwings pale yellow. 
Peru. 
P. ectrocta Dogn. (32 h). Head, thorax, and abdomen yellow, the latter two above mixed with brown, edrocta. 
ForeAvings yellow with a large, U-shaped brown spot broadly bordering on the proximal margin. Hindwings 
light yelloAv. Colombia. 
P. perdiffusa Dogn. (32 h) is more slenderly built, with more extended forewings exhibiting in the perdiffusa. 
$ beneath in the cell a roughly haired excavation; above it there are black scent-scales, in the cell-end a silvery 
lustrous, black hair-tuft, and a hairy oblique stripe crosses the lower median vein. The body is yellow-brownish, 
the forewings yellow Avith reddish-brown nebulous bands before and behind the middle. Himhwings light yellow. 
Colombia. 
68. Genus: JKugoiaosia Hmps. 
Distinguished by the entirely stunted proboscis and palpi; posterior tarsi with moderately long spurs. 
On the forewing the upper median vein rises petioled with the loAver radial from the loAver cell-angle; aboA^e 
it the middle radial comes forth; the upper one is petioled with the 3 lower subcostal veins, the two upper ones 
terminate into the costal margin. On the hindwing there are quite the same conditions, the upper radial on 
a very long footstalk with the subcostal vein. Only 1 species known. 
E. angulifer Schs. (36 a). Head and thorax orange, overfloAvn with pink, abdomen rosy red; antennae angulifer. 
blackish-broAvn, curled Avhite. Forewings orange, tinted rosy, with black margins and a black angular marking 
being open downward. Hindwings rosy with orange fringes. Expanse of Avings: 24 mm. Brazil: Castro (Parana).
