yellow. 18—-19 mm. Paramaribo and in Rio de Janeiro ; figured according to a specimen collected by Dr. Seitz

with yellowish brown rings, a broad yellowish brown spot on the 2nd segment. Anal tuft brown and black. 
Legs yellowish brown. Fore wing hyaline, costal margin, veins and apex black, a black streak at the end of

Guiana. 
S. laticraspedontis sp. n. (176 h) is allied to wagneri Le Cerf (176 b), but it has quite yellow palpi. Thorax 
black, posterior margin yellow. Abdomen black, slightly dusted with yellow, the posterior margin of the 4th 
and 6 th segments yellow. Anal tuft dull black, yellow below, the 2 nd, 4th, 5th and 6 th segments on the ventrum 
broadly edged with yellow. Legs yellow, femora and the end of the tibiae black. Forewing transparent, the 
veins, the discal vein and the very broad distal margin black, the inner margin broadly dusted with yellow; 
beneath the costal and posterior margins as far as the discal vein are broadly yellow, the discal vein and distal 
area, black, the latter powdered with white. Hindwing transparent, the veins and margins black, the last part 
of the discal vein colourless. The fringes of all the wings yellowish brown. 19'5 mm. Brazil, Itatiaya, January, 
1 $. Type: Coll. Marten. 
S. xanthoneura sp. n. (177 a). Head black, with yellow hair behind. Palpi yellow, the 1st and 2nd joints 
very hairy, the 3rd short, pointed and blackish. Antennae black. Thorax black with medium strong yellow 
lateral stripes. Abdomen black with a yellow lateral line. Anal tuft black, yellow below. Forewing hyaline, 
the transparent areas normally developed; the costal margin, distal margin and discal vein black, the most 
extensively black in the apical angle Inner margin, the margin before the distal area and the veins yellow. 
Hindwing hyaline with normally black margins and yellow veins Femora of all the legs black, tibiae yellow, 
the posterior ones with long light terminal and middle spurs, the tarsi with yellow and black rings. 19 mm. 
1 d- Villarica, Paraguay. — It belongs near to S. wagneri Le Cerf , from which, however, it is above all easily 
discernible by the entirely yellow veins, besides the differences mentioned above. Type: Coll. Zukowsky. 
S. guyanensis Le Cerf ( % = surinamensis Mschlr.) (176 c). Head blackish blue, the face bronze-coloured, 
broadly white before the eyes, the 1 st joint of the palpi black, the 2 nd yellow below, black laterally at the base,

segment partly yellow, the 1 st, 2 nd and 3rd laterally yellow and the margin of the 4th quite yellow. Legs 
black and whitish. Forewing transparent, the margins, veins and discal mark chiefly blackish blue, the discal 
vein is very narrow, the distal margin broad, the exterior hyaline area quadrangular, traversed by 5 veins, 
the costal vein and distal margin beneath yellowish. Hindwing transparent, the veins, margins as well as the 
fringes of all the wings purple black. 18—20'5 mm. French Guiana. Only $$ are known so far. — var. clara 
Le Cerf (177 a) is distinguished by a much narrower distal margin which appears concave at the apex at the 
previously forked veins 7 -|- 8, where it bends round and becomes broader. 19 mm. French Guiana. — Though 
the species seems to be closely allied to surinamensis Mschlr., Le Cerf considers guyanensis to be a separate species. 
S. anomallformis Wkr. Blackish purple. Face white, palpi yellow, the 3rd joint only of half the length of 
the 2nd. Antennae ochreous, plain, thickened before the end. Thorax with three yellow stripes, breast yellow. 
Abdominal segments with yellow posterior margins, underside and the long anal tuft yellow. Legs yellowish. 
Forewing transparent, with a purple reflection, the margins and the cross-vein coppery brown, fringe the same. 
Hindwing transparent, fringe coppery brown. 17- 18 mm. Specimens are also reported with more or less 
black antennae. Tapajoz, Villa nova. Only dd known. 
S. basalis Wkr. (176 c). d : golden yellow. Face silvery white like the orbita. Proboscis very short. 
The 3rd palpal joint pointed, half as long as the 2nd. Antennae long, black, with an apical hook. Thorax cop- 
pery with three yellowish stripes. Abdomen above purple, the posterior margins of all the segments silvery. 
Anal tuft very long, black, silvery beneath at the base with projecting hair-tufts on the sides. Legs long, hind

line purple, hindwing transparent with purple margins. $: palpi longer, antennae shorter, thorax with two 
broad coppery stripes. Abdomen long fusiform. Legs quite golden yellow. 24—25 mm. Ega. — It resembles 
anomaliformis and dinetiformis (p. 1223), but it is especially distinguished by the compressed body.
