S. hampsoni Barnes greatly approximates joda (16 cl) from which it differs by subdorsal orange-yellow 
spots on all the abdominal segments. Forehips inside whitish, outside yellow; the anal tuft is only above yellow, 
at the sides and at the end black. The yellow ventral valve is bordered with black, and the venter exhibits 
yellow bands. — befana Skinner which was based on one example, scarcely differing, may be synonymous. 
From South Arizona. 
S. melanthus Cr. (= apricans Wkr.) (16 cl). Black with a bronze-green, blue or violettish-blue lustre. 
Antennae black with white tips; collar and shoulders with orange spots; sides of thorax and hips with white 
spots. Abdomen with white bands merging into deep orange-yellow and which always remain white on the 
ventral side. Forewings with pale greenish-yellow spots: a large one below the base of the cell, one in the middle 
of the cell, and one close beneath it, and 4 in one row behind the cell. Hindwing with a white hyaline spot parted 
by the veins at the base, and 2 pale-yellow spots behind the cell. The extent and number of the spots varies 
greatly. Common from Mexico through the whole of Central America as far as Uruguay and Peru. — f. nycteus 
Stoll are specimens with greatly reduced spots on the wings. — nexilis form. nov. (= ab. 2. Hmps.) may be 
introduced for those specimens in which the two spots below the cell are confluent. -— f. albifasciata Btlr. (16 e), 
finally, are the specimens with more or less white abdominal rings, in contrast with the yellow-curled type. 
S. austera Dogn. is much smaller than the preceding; head and thorax cpiite black with a deep green 
lustre, of the same colour is the abdomen exhibiting on the two first rings yellowish-white, on the 4 next ones 
dark brick-red belts; venter with white bands; hips with white spots, as well as the femoral joints of the hindlegs. 
Tips of antennae white. Forewing with a yellow dot at the base, a larger yellowish-white spot behind it between 
the median and inner-marginal vein, and a small round spot behind the cell between the upper radial and 5th 
subcostal vein. Hindwing with several spots, being hyaline at the base, yellowish in the cell. Expanse of wings: 
38 mm. Paraguay. 
S. syntomoides Bsd. (= saulcyi Guer., niveifascia Wkr., wrighti Gundl.) (16 e). Black with a blue 
lustre. The arrangement and number of spots, being here all white and somewhat diaphanous, is similar to that 
of melanthus. The first segment of the bluish-black abdomen exhibits a white band, which may also be broken 
up into spots or be absent altogether. The three middle segments exhibit on the ventral side white transverse 
bands. Preponderantly insular inhabitants: Cuba, Bahamas, St. Lucia, Dominica, Barbados, Martinique, 
but also from Mexico: Cordoba, Misantla, Tehuacan (Puebla) in April and September. — ab. angasi Druce 
has an entirely black ventral side without any white bands. •—- f. spiracula Men. shows the spots on the 
wings greatly reduced, the spots in the cell or below the first radial vein are mostly absent altogether; on the 
hindwing the spot above the 2nd radial is absent. —- f. vidua Men. On the forewing also the spot below the 
middle of the cell is more or less extinct, on the hindwing the inner-marginal spot is absent. 
S. vulcana Druce (16 e). Bluish-black; sides of thorax and the hindhips with white spots. The abdomen 
exhibits on the 1st ring a white dorsal dot and subdorsal spots, and on the 3 middle segments sublateral white 
spots. The forewing exhibits at the costal base, below the base of the cell and in the middle of the cell yellowish- 
white dots. The hindwing with a hyaline basal spot. Expanse of wings: 54 mm. Mexico. 
S. ipomeae Harr. (— ferox Wkr., euterpe H.-Schaff.) (16 e) is bluish-black on the head and thorax; 
collar, shoulders and thorax above and laterally with orange spots; hips orange; abdomen with broad orange 
bands. Wings metallic bluish-black, the forewing with an orange-yellow dot at the base, as well as small yellowish- 
white spots of various development below the base and middle of the cell, behind the upper cell-corner and 
2 larger ones behind the lower cell-corner. The hind wings show a hyaline spot below the base of the cell. Expanse 
of wings: 48 mm. Southern United States. 
S. epilais Wkr. (16 e). A beautiful, large, bluish-black species with white tips of the antennae. The 
forewing exhibits at the base of the costal margin a small, snow-white spot, another round one is below the 
middle of the cell, a small one at the end of the cell and 4 unequally large ones behind the cell. The hindwings 
exhibit behind the cell-end a white spot. The first abdominal ring exhibits above 2 large white spots with one 
or 2 dots between, the 3 following rings have lateral white spots. The last 2 abdominal rings are of a deep carmine. 
Mexico to Honduras. -— The red larva with black hairs and hair-pencils on the 3rd, 4th, and 7th to 13th segments, 
with an orange-red head, according to Dyar, lives on Nerium odorum and constructs a thin cocoon interwoven 
with its hairs, in which it changes into an orange pupa with black stripes and bands. It flies in Mexico from 
February to July. — v. jucundissima Dyar (— epilais Neum. and Dyar) is the form from Florida. 
51. Genus : liuope Wkr. 
Of a much more robust structure than the preceding genus with broader wings. Palpi shorter, more 
porrect and long haired. The whole body is densely covered with long, shaggy hair. In the neuration no essential 
difference. Only one species:
