fringes greyish bronze. 24 mm. Brazil, Prov. of Rio de Janeiro. August till September. Only 1 $ known hitherto. 
The type is without the middle and posterior legs, nevertheless Le Cere considers it necessary to establish 
a new genus for this species. 
4. Genus: Syiiantliedoii Him. 
Tongue well developed, antennae thickened shortly before the end with a small hair-bristle at the end. 
mostly feebly ciliated in the + The fore wing always with all the three hyaline areas, veins 10 + 11 extending 
parallel with the distal margin. Hindwing with veins 3+4 on the same short stalk. — Type: S. vespiformis 
L. from Europe. 
S. giliae Hy. Edw. {-= vitrina Neum., deceptiva Beut.) (177 a). head black, face pale yellorv. palpi 
yellow, with black hair outside, collar yellow in front. Antennae black, thorax black with a few r yellow hairs 
at the end of the patagia. Abdomen black with yellow bands on the 2nd, 4th and the last two segments, the 
under surface also with bands or sometimes quite yellow. Anal tuft yellow, black above. Legs yellow with 
black bands on the tibiae. Forewing transparent with narrow black margins and a strong cross-vein, the latter 
outwards frequently with red. Hindwing transparent with narrow black margins. — head black, face and 
palpi yellow. Wings with brown margins, the discal mark brownish orange outwards, quite orange below. Ab¬ 
domen with three yellow bands on the 2nd, 4th and 6th segments. Under surface with traces of a band on 
the 5th segment. Anal tuft yellow mixed with black. 20—25 mm. Colorado, Montana, British Columbia. 
Huachuca Mts., Arizona. 
S. rileyana Hy. Edw. (176 a). : head black, face and palpi yellow, black outside. Collar yellow in 
front and behind. Thorax black, patagia yellow behind, a yellow transverse streak and yellow spots at the 
base of the forewing. Antennae black, distinctly pectinated. Abdomen black with six lemon-coloured bands, 
the basal segment without a band or with traces of it. Anal tuft black and yellow. Legs yellow with black

margin, a very broad distal margin, so that the transparent spot in the distal area becomes very small. Cross- 
vein strong, brown, red outside. Beneath the costal and inner margins yellowish. The distal areas between 
the veins red. Hindwing with broader margins than in the + beneath more or less reddish. 20—30 mm. —- 
var. hyperici Hy. Edw. shows a very thin costal -marginal streak of the forewing. — In var. brunneipennis Hy. 
Edw. (176 a) the margins of the forewing are so broad in the $ that very little remains transparent. 
S. mimuli Hy. Edw. Head black, face white, palpi dingy white, outside mixed with brownish hairs. 
Antennae black, thorax black, all the yellow markings of rileyana being dingy whitish yellow here. S. mimuli 
may be a local variation of S. rileyana (176 a). Only l $ known. 21 mm. Colorado.
