S. mecrida Bruce (= dulcicordis Dyar ) (15 e). The delicate, long-extended wings are blackish dia¬ 
phanous, abdomen and mesothorax of a magnificent scarlet, the collar is bordered with bluish-white. The 
exhibits more, less developed, black spots on the dorsum and the sides of the abdomen. It flies in October 
and November in Mexico (Mexico City and Durango). 
S. ochracea Fldr. (= musca Schaus, pontia Druce) (15 e). The tiny, gnat-like insect is blackish 
except the ochreous-yellow abdomen, with semi-diaphanous, long, narrow wings. Flying in March to September 
in Mexico (Orizaba, Misantla, Coatepec) and in Colombia. 
S. improvisa Schaus. Easily distinguishable from the preceding by its orange-yellow thorax being 
anteriorly spotted black and white. Shoulder-covers black; the abdomen on the first segment subdorsally spotted 
black. The wings are more brownish hyaline, in the distal third thinly scaled. Veins and fringes blackish -brown. 
Expanse of wings: 24 mm. Costa Rica. 
S. bicolor Dogn. differs from ochracea (15 d) by its blackish-brown forewings exhibiting narrow hyaline 
stripes only in and below the cell, and by the hyaline hindwings with brown veins and margins. Besides, the 
abdomen being yellow in the <$ shows a black dorsal line and, beginning from the 4th ring, also lateral stripes. 
In the $ the abdomen is carmine instead of yellow. Argentina (Tucuman). 
S. tricolor Schaus has an orange body, only the head with the antennae and the 4 last abdominal 
rings are black. Femora and tarsi yellow, tibiae black, forewings black, in the median area ochreous yellow, 
hindwings ochreous-yellow with a broad black margin. Expanse of wings: 23 mm. French Guiana. 
S. hamon Druce. Body bluish-black, collar red-brown. Legs dark brown. Forewings lustrous reddish- 
brown. Hindwings hyaline, margins black, with an intense blue lustre. Expanse of wings: 35 mm. Peru. 
S. cryptoleuca Wkr. (15 f) is, with the following, the sole species with light metallic, bluish-green 
hindwings and thereby very easily recognizable. The body and the forewings are black; vertex, collar, legs, 
base and sides of abdomen are spotted metallic bluish-green. On the shoulders and at the sides of the 1st abdo¬ 
minal ring carmine spots. The forewings exhibit stripes of metallic bluish-green scales in, behind and below 
the cell. The hindwings are diaphanous below the cell and at the proximal margin, the veins and margin being 
black. Forehips and ventral side white. Described from the Amazon; in my collection also from Guiana, and 
from Venezuela. 
S. watsoni Rothsch. (15 f) is easily distinguishable from the preceding by the hyaline spots on the 
forewings being peculiarly distributed. Panama (Chiriqui). 
S. biradiata Fldr. (15 f). Body black; hips, stripes at the front femora and ventral side white. Fore¬ 
wings black, below the base of the cell thinly scaled, in the cell-end 2 bluish-green stripes; behind the cell, 
between the 2nd median and 4th subcostal vein there are hyaline spots. Hindwings hyaline with black veins, 
margins, apical and inner-angular spots. Expanse of wings: 28 mm. Amazon. 
S. tristissima Perty (15 f) shows on its velvety black body small metallic green spots, and at the 
side of the 1st abdominal ring as well as at the base of the forewing small red spots. The wings are hyaline 
with black margins and veins. Amazon (Para, Massauary). 
S. attenuata Hmps. (= tenuis Bt-lr.) (15 b). Body black. Shoulder-covers and base of the wings 
spotted red; hips and femora with white stripes. Wings hyaline with black veins, proximal margin and apical 
spot. Expanse of wings: 22 mm. Amazon. 
S. diffusa Schaus (15 f). The $ is distinguished by quite uncommonly broad forewings and parti¬ 
cularly hindwings, in the $ they are narrower. Body and wings are sooty black. Bright metallic green spots 
are on the forehead, sides of the vertex, collar, metathorax and at the sides of the abdomen. Spots on the shoul¬ 
ders and a large square spot on the base of the abdomen are carmine. Forehips metallic green. Costa Rica. 
S. latens Schaus has a black body with red spots on the shoulders and dorsally on the 1st abdominal 
ring. Anterior tibiae inside yellow-reddish. Wings blackish-brown with darker veins. Expanse of wings: 
25 mm, $ 30 mm. Costa Rica. 
S. submacula Schaus is dark brown on the body and wings; the shoulders exhibit a large carmine 
spot; on the forehead, collar and mesothorax, as well as at the costal base single blue scales. On the hindwings 
below the base of the cell there is a reddish stripe and a small pink spot. Expanse of wings: 36 mm. Costa Rica. 
S. hemiphaea Dogn. Body black with some small, metallic green scales; outside at the collar a white
