NEOTHYSANIS; PROUTOSCIA; ASELLODES. By L. B. Prout. 
simplicis- T. simplicissima Dyar is unknown to me and I doubt whether it belongs to this genus. “Wings trans- 
sima. ] uceil t whitish, thickly irrorated with pale grey, the irrorations largely confluent; forewing with 2 lines of grey, 
wavy, approximate, subparallel; hindwing with a single mesial line; a dark line on margin of both wings; outer 
margin angled at vein 4 on both wings. Expanse 36 mm. Orizaba, Mexico, a 
10. Genus : JSfeotliysaiiis Dogn. 
Another offshoot of Semaeopus, differing chiefly in having the distal margin of each wing sharply angled in 
the middle. Antenna of A ciliated. Pectus not so strongly hairy as in typical Semaeopus, hindleg similarly 
aborted and tufted in the <$, in the $ with all spurs. Type of the genus, bicolor Dogn. 
aloxogram- N. aloxograninia Prout (12 a) differs from the other species chiefly in the formation of the lines, the 
ma - antemedian excurved and waved the postmedian placed at % the wing-length, gently sinuate. Bolivia: Rio 
Suruta, 1 A- 
imella. N. imella Druce (12 b). Founded on a single $ from San Geronimo, Guatemala, and regarded, though 
doubtfully, as an Erosia ; may perhaps represent a different race from the forms which have subsequently been 
received, though sparingly, from French Guiana, S. Peru, Bolivia and Brazil, the colour in them being of a 
brighter, less greyish brown. The straight, oblique outer line is generally very distinct, finely pale-edged prox- 
imally. 
bicolor. N. bicolor Dogn. may well, according to the decsription, be merely a colour-form of imella, the black 
line bordered on each side with “gris marron", the pale line on its proximal side rosy, the ground-colour beyond 
the line darker than proximally. Zamora, near Loja, 1 q. 
11. Genus: Proiitoscia Schaus. 
Near Asellodes, of which it might easily be treated as a section, differing chiefly in wing-shape. Both 
wings more rounded than in any Asellodes, the A hindwing with a much narrower excavation than that of A. 
fenestraria, probably its nearest relative; discocellulars not so sinuous. 
mirifica. P. tllirifica Schaus (12 b). A large and striking species, with the hyaline area of each wing ample, quite 
differently shaped from those of any known Asellodes. Hindwing beneath in front of the 2nd radial with a ridge 
of long, curled hair, the whole terminal region from the 1st radial to the posterior excavation similarly clothed. 
Costa Rica. 
12. Genus: Asellodes Guen. 
A remarkable genus, with some of the characters of Trygodes — fasciculate A antenna, tufted A hindleg, 
double areole of forewing, 2nd subcostal arising from the cell —, but probably well isolated. Hindtibia of $ 
with all spurs. Wing-shape very irregular, that of the hindwing differing greatly in the sexes; in the typical 
group the A hindwing has the termen excavated posteriorly, fringed more or less strongly with hair on the 
underside at the excavation. Very characteristic are the extensive hyaline patches. In the venation the most 
striking feature, at least in the typical group, is the point of origin of the 2nd radial, which arises much nearer 
to the 1st than to the 3rd. The genus is exclusively Neotropical. 
A. Hindwing of A without hair- fringed excavation posteriorly! Pseud- 
asellodes Wan. = Oxypterodes Oberth.) 
constcllata. A. constellata Warr. (= dapalis Oberth.) (lli). A rather large and brightly coloured species, known 
at once by its shape and markings. The ^ is unknown to me, the A common in E. Peru, especially at Huanca- 
bamba, Cerro de Pasco. 
lacunata. A. lacunata Dogn. (= daphnogethes Oberth.) (12 b). Much smaller, shape less extreme, the hyaline 
markings differently arranged. N. Argentina and Paraguay, the type from Tucuman. I know AS only of this 
cassiopcia. form. — Cassiopeia Bastelb. (14 a). Much greyer, otherwise scarcely distinguishable. I know $$ only, a little 
larger than the preceding, and should confidently have treated it as the $ to lacunata but that Dogn in's “rosy” 
type was a and Bastelberger possessed both sexes of the “blue-grey” Cassiopeia . Probably they are 
bahiana. colour-forms, chiefly but not exclusively sexual. Tucuman. — bahiana subsp. nov . $ unknown. A brighter 
than that of lacunata, almost as clear vinaceous as in laternaria, only the (narrowed) outer band greyer; central 
hyaline patches of forewing more broadly confluent, subterminal line less sinuous. Bahia (Penther expedition): 
Rio Preto, between Boquerao and Sta. Rita, the type in the Natural History Museum, Vienna, a paratype 
in my collection.
