S. xanthotarsis Lath/j is closely allied to the preceding, but easily discernible by quite orange-coloured xanthotar- 
tarsi and proximal margin of the forewing, the veins being also orange-coloured towards the base. From Vene¬ 
zuela; may-be only a form of sesiiformis. 
S. epona Dogn. is allied,to the preceding, though it is smaller and differs by its more extensive yellow epona. 
colouring; head and thorax are yellow; costal and proximal margins of the forewings are likewise yellow, so 
are the veins in the proximal half of the wing. Expanse of wings: 33 mm. Venezuela. 
S. xanthobasis Druce (11 f). This beautiful, large species has an orange-yellow thorax and abdomen, xanthobasis. 
Head and collar black with metallic blue spots. The 3rd abdominal ring exhibits above a small, black spot 
which may also be absent, the 4th a triangular, small, black spot adjoining the last, black, metallic blue reflecting 
segments. Wings hyaline with black veins and margins, the base of the forewing is orange. Hitherto known 
only from Ecuador. 
S. connotata Hmps. (Ilf) forms the connecting-link between the preceding species and the following connotate/, 
notata ; from the latter, to which it is very closely allied, it differs by the base of the wings being orange-yellow 
like in xanthobasis, furthermore by a large black spot on the metathorax and by the somewhat more extensive 
black colour of the abdomen; the triangular, black, metallic blue-pupilled dorsal spots have their points towards 
the head, their bases being directed analwards, what in notata is more or less distinctly just the contrary. 
Another mark of distinction is the very small lower half of the discocellular of the hindwing: in notata it is much 
larger, for which reason the veins 2 and 4 are much shorter petioled. Distributed from Venezuela (Merida) 
to Peru. 
S. notata Btlr. (= ufentina Druce) (11 f) greatly resembles connotata, but immediately distinguishable notata. 
by the black, not orange base of the forewing, the shoulder-covers being also black-margined. The abdomen 
exhibits above a more or less developed row of black, metallic-pupdied spots which may also be entirely absent: 
innotata form. nov. (= ab. 1 Hmps.) (11 f). The species occurs in Colombia, Bolivia, Peru, Ecuador und Vene- innotata. 
zuela (Merida), whilst innotata originates from Ecuador. 
S. acutior Fldr. (11 g) is smaller than the preceding and at once recognizable by the orange head. The acutior. 
first 4 abdominal rings are orange-yellow, black-margined, the 2nd segment exhibits a broader band with blue 
subdorsal spots in it; the last segments are black with small, subdorsal macular stripes. Wings yellowish hyaline 
with fine black veins and margins; the costal-marginal area orange, as well as the proximal margin and the 
apex of the hindwing. Ecuador, Amazon. 
S. boenninghauseni Rothsch. (11 g) faintly resembles Isanthrene basifera (10 a) or joda. The body boenning- 
is black. Neck and thorax exhibit some orange hairs. At the abdomen steel-blue lateral spots, on the first 
segment above a yellow transverse-streak, the second and third exhibit yellow rings. The wings are yellowish 
hyaline, the costal margin, the cell-end and the basal inner-marginal half are orange; a subbasal spot above 
vein 1, the distal half of the proximal margin and the distal margin are grey-brown, a grey-brown, large spot 
lies at the anal angle of the hindwing. Described from Brazil (Rio de Janeiro). 
S. klagesi Rothsch. (11 g). Black; the forehead is yellow-margined, vertex metallic violet-blue; collar klagesi. 
and shoulder-covers at the base yellow-spotted. Abdomen dorsally and laterally with metallic violet-blue 
spots. Wings yellowish hyaline with black veins and margins, at the base of the forewing a metallic-blue spot; 
on the hindwings the black distal margin projects inwardly like a tooth near the proximal angle. The legs are 
black, the tibiae metallic blue with a black ring, the tarsi orange. Venezuela. 
S. helotes Druce. Head deep metallic blue; collar, thorax and abdomen brilliant orange, collar black- helotes. 
margined; the abdomen shows 3 rows of metallic blue spots, the last segment being black. Wings as in the 
following. Expanse of wings: 50 mm. Colombia. 
S. ozora Druce (11 g) has a brownish-black body, posteriorly with a greenish reflection; antennae-tips ozora. 
and tarsi white. The 1st and 5th abdominal rings exhibit above orange bands, the latter also lateral spots. 
Wings hyaline with narrow black margins and veins, the forewings are greenish at the base and along the proximal 
margin. Expanse of wings: 44 mm. Colombia. 
S. lutibasis Hmps. Body deep black; forehead, vertex, collar, metathorax, femora and tibiae blue- lutibasis. 
spotted; hind-hips yellowish-white. The abdomen exhibits on the first ring a yellowish-white basal spot and 
articular line, on the second ring sublateral yellowish-white spots, and on all the segments subdorsal, metallic 
blue spots. Wings yellowish hyaline with broad black margins and veins; at the base a blue spot; at the costal 
margin and above and beneath vein 1 orange stripes. Expanse of wings: 36 mm. Panama. 
S. pompilina Btlr. (11 g) greatly resembles the preceding and mora, but it is not so jet-black, but pompilina. 
more brown-black; shafts of the antennae above red. The blue-black abdomen shows a whitish basal spot, 
subdorsal, leaden-coloured stripes and white lateral spots. Wings yellowish hyaline, costal margin and base 
of the proximal margin striped in carmine. Panama; Ecuador; Brazil.
