S. tridurotna H-Schaff. (31 k) is much smaller, lighter, more greenish grey, strewn and in some places inchroma. 
irrorated with brown, in the hinclmarginal part of the central area often almost white, with double transverse 
lines and lighter maculae which are not surrounded by dark; of the internerval streaks in the marginal area 
of the preceding species there is only one present on the submedian fold. Hindwing greyish-brown, towards 
the base whitish. Bahamas, Cuba. 
S. aenyra Drc. (= sabrella Schs.) (31 k). Forewing dark red-brown, strewn with black, with black aenyra. 
transverse lines, the anterior line indistinctly, the posterior line partly double, and with black irroration between 
both along the submeclian fold; the maculae are hardly surrounded with dark, instead of the undulate line there 
are small ochreous-yellowish spots proximally bordered by black. Hindwing red-brown. Mexico, Panama to Brazil. 
S. leucosticta limps. (31 k) is similar, but of a more reddish tint with purple red striped veins, and leucostidct. 
discernible by yellowish-white dots in the macular bordering, also behind the distal transverse line. Venezuela. 
S. randa Schs. (31k). Forewing red-brown, strewn with yellowish-white, with black undulate transverse randa. 
lines edged with ochreous-yellow, and a blackish-brown spot between both behind and below the coniform macula, 
the upper maculae are bordered by white dots; the yellowish-white undulate line is on both sides bordered with 
brown. Hindwing yellowish-white with a red-brown marginal band and postmedian line before it. Trinidad. 
S. chromatica Hmps. (32 a) is smaller and darker, reddish greyish-brown, strewn with black, in the ehromatica. 
middle of the central area irrorated with blackish-brown; the double transverse lines are filled rip with reddish, 
the maculae are small, in pinkish-reddish rings, instead of the undulate line there are small reddish lunae with 
small black sagittae before them. Hindwing white with a greyish-brown marginal band, in the $ yellowish-grey, 
broadly margined with brown. Venezuela, Paraguay. 
S. nigrofasciata Zerny (33 k) is easily discernible by the broad blackish-brown central area of the nigrofascia- 
forewing which is otherwise brown mixed with ochreous and strewn with bluish-white; the strongly undulate ia - 
double transverse lines are filled up with ochreous; only the brownish indistinctly defined reniform macula 
is visible, the undulate line consists of ochreous roundish small spots distally bordered with dark brown. Hind¬ 
wing diaphanous white, with a broad blackish-brown marginal band. Bolivia (Rio Songo). 
S. eugrapha Hmps. (31 k) is much smaller with entirely white hindwings. The ground-colour of the eugrapha. 
forewing is ochreous-yellow, irrorated with red-brown, the veins are irrorated with purple, with threefold dentate 
transverse lines and brown-ringed maculae; behind the rather indistinct, proximally black-spottecl undulate 
line there is a double row of dark dots. Brazil to Paraguay. 
S. grandimacula Schs. is allied to aenyra (31 k), brown, strewn with black, with grey veins and velvety- grandima- 
black fine transverse lines, the posterior line being distally bordered with light brown, submedianly with white; Cllia ' 
the hindmarginal half of the central area is deep velvety blackish-brown, two similar spots are in the marginal 
area, the upper one being much smaller; on the margin there are white vein-dots. Hindwing brown. Costa Rica. 
10. Genus: Cropia Whr. 
Palpi still longer than in the preceding genus and thickened at the ends, often almost knob-shaped; 
frons smooth, without projection. Of the abdominal tufts those at the base and in the centre are the largest 
and often exhibit a very strong and dense development. Of the numerous tropical American species one goes 
as far as the United States. 
Sect. I. $ antennae with rather long pectinations, at the apices serrate. 
C. subapicalis Wkr. (32 a). Forewing reddish-brown, strewn with black and white, with double siibapicaUs. 
transverse lines, the posterior line filled up with whitish, the maculae surrounded with black, with single white 
dots around them; in the postmeclian area below the costal margin a white spot, distally traversed by an undulate 
brown line; before the white undulate line at the anal angle and behind the cell black spots, the upper one 
continued also behind it. Hindwing reddish-brown. From Hayti. 
C. ruthaea Dyar (32 a) looks like connecta (32 c), but it is smaller, with broader wings and longer ruthaea. 
pectinate antennae. Forewing dark brown, in the basal area and subterminally lighter ochreous, the interior 
black transverse line deposited below the costal margin, submedianly and on the hindmarginal vein distally 
angled, from the upper angle a black streak to the double postmedian line; the large maculae are surrounded 
by black and with concentric rings; in the marginal area there are black streaks which partly cut the yellowish 
undulate line. Hindwing dark brown. Mexico. 
C. maudaea Dyar (32 a) is extremely similar to ruthaea. the antennal pectinations are somewhat mandaca. 
shorter; the ground-colour is darker, more faded, without the basal and subterminal lighter parts; the marginal 
streaks are shorter and more indistinct, the hindwing is more monotonously dark. Expanse of wings: 33 mm. 
Mexico (Zacualpan). 
Sect. II. S antennae with shorter lamel-shaped pectination s. 
C. europs Dyar (32 a) is a very large species very dissimilar to the others. Forewing dark brown, europs. 
suffused with dark blue in the basal area, submedianly and behind the cell; transverse lines double, maculae
