S. tribuna Hbn. (= continua Wkr., schausii H. Ediv.) (1 cl) is easily recognizable by the long, yellow 
basal spot of the forewing and the long longitudinal stripe of the hindwing. Mexico, Honduras, Guatemala, 
Nicaragua, besides in Hayti and Cuba. 
S. praefecta Drc. (1 e) looks very much like panamensis and volupia, and is discernible by a much 
broader black abdominal stripe and a broad black costal margin of the hindwing. In the nomenclatural type 
the orange oblique stripe of the forewing is almost extinguished by brownish scales, in elaphebolia it is distinctly 
prominent, and in ab. nervalis Strd. (1 d) it is much shorter, whilst there is another, smaller spot in the basal 
half and the yellow of the hindwing more reduced. From Ecuador, Bolivia and Peru. 
S. meridiana Schs. (1 e) differs from elaphebolia by the hindwing being black with a pear-shaped, 
orange-yellow spot leaving the costal margin broadly black as far as into the cell. From Brazil (Sao Paulo). 
S. columbina Ww. (1 e) looks like 0. augias, but anteriorly it has an orange-yellow collar, and a 
yellow spot at the palpal base. Colombia. 
S. extensa Jord. Brown, collar anteriorly and abdomen yellow, the latter with a narrow dorsal line. 
Forewing above with a broad, yellow band being broadest at the lower cell-angle. Hindwing yellow, costal 
margin and distal margin edged with black as in lindigii Fid?'. Fringes at the proximal margin likewise black. 
Beneath the forewing shows a large, yellow triangular spot in the basal half, the hindwing is as above. Length 
of wings: 28 mm. Colombia (Rio Dagua and Popayan). 
12. Genus: I*Iiasi<Sia H?nps. 
Palpi much longer than in the other genera, particularly the 3rd joint which is bare and shows straight 
forward; the long frontal projection is coniform; the antennae are very much thickened towards the tips, almost 
club-shaped. The tibiae are only little haired, the abdomen smoothly scaled. On the forewing the upper radial 
vein comes from below the upper cell-angle and the accessory cell is very minute. Only 1 species is known. 
P. contraria Wkr. (= meridionalis Schs.) (1 e) is blackish-brown with a slight blue reflection and 
an oblique, pale yellow transverse band of the forewing. Brazil, Peru. 
13. Genus: Phasis Wkr. 
Distinguished from the preceding by thinner antennae, shorter palpi and a somewhat larger accessory 
cell of the forewing on which the upper radial vein rises from the upper cell-angle. 
P. noctilux Wkr. (= batesi Fldr.) (If as phasis) resembles contraria , but it is somewhat larger and 
lias orange-yellow margins behind the eyes, of the same colour are the base of the palpi and lateral spots ou 
the chest. Amazon District. 
P. mardava Drc. (1 e) is blackish-brown without the blue reflection of the similar species, with 
a very irregularly defined, light yellow oblique band of the forewing. Amazon Distiict. 
14. Genus: Xerociris Cock. 
With this genus we add to the Agaristids that group of Noctuinae which corresponds in the Indo- 
Australian part to the Seudy?-a and Zalissa and which would be better inserted in the A cron yctinae in Hampsox’s 
sense, particularly because the antennae are partly combed and not thickened. The rest of the structure, however, 
corresponds well. They especially are also biologically closely allied, for the larvae, as far as they are known, 
are externally very much like those of the Agaristids and they likewise live on the vine. The long frontal pro¬ 
jection is of a pointed conic shape; the moderately long palpi are smoothly scaled, the shoulder-covers long¬ 
haired; the base of the abdomen exhibits a large dorsal tuft. The neuration does not deviate, except the upper 
radial vein on the forewing rising from the accessory cell. Onty 1 species. 
H. wilsoni Grt. (1 f) has silvery white forewings with olive-green spots at the costal margin and 
proximal margin and maculae, whilst a marginal band is purple grey with a fine white marginal line. Head 
and thorax brown and bluish-black, shoulder-covers and abdomen white with brown dorsal tufts. Texas. -— 
The larva with a somewhat raised anal segment is purple black with several narrow white transverse lines on 
each ring and red ventral spots. Head, neck and anal valve as well as the feet are red. On the thoracal rings 
and the last segment there are very long, flattened spatulate hairs. 
15. Genus: fraitiiisaHotia Hbn. 
Distinguished from the preceding by its rounded frontal projection with a horny plate below it; 
antennae ciliated; the anterior tibiae show outside very long hair-tufts; on the forewing the upper radial vein 
comes from the upper cell-angle.
