SEMAEOPUS. By L. B. Prout. 
83 
S. mira Prout (10 f). Brighter red than any other Semaeopus, costal edge of forewing blacker. Re- mira. 
markable for the $ structure: hindwing with cell-fold very strong, almost vein-like, 2nd radial very weak, 
appearing as an anterior branch of the radial fold. Huancabamba, Cerro de Pasco only, the type known. 
S. tropaea sp. n. Near mira (lOf), sharing with it the atrophy of the 2nd radial of the hindwing. Hindleg iropaea. 
still more aborted, with the tufts rather strongly reddish. Hinclwing beneath clothed, from base to end of 
cell, with specialised coarse reddish scaling, proximally in part hair-like. Upperside with the red coloration 
not quite so bright as in mira, the 1st line dark grey, not red, the median excurved almost as in lunifera (10 d), the 
fine yellow edging of the postmedian wanting; hindwing with only one black cell-dot (the anterior). Hindwing 
beneath with the median line obsolete (in mira distinct). Taperinha, near Santarem, 1—10 July 1927 (Dr. H. 
Zerny), 2 dH, type in Museum Wien. 
S. exquisitata MoschX. (10 f). Rather short-winged, the grey median area very broad, the paler distal exquisitata. 
parts small but bright, subterminal, not terminal. Hindwing beneath in $ with coarse reddish scaling at base, 
together with a small hair-tuft curved outwards and lrindwards over base of cell. Described from Surinam, 
but reaches Panama and the Low r er Amazon. 
S. plumbeostrota Prout (10 f). Colours nearly as in exquisitata, their distribution very different, wings 
somewhat less shortened. $ hindwing beneath without the basal specialisations. Widely distributed, Trinidad 
and Venezuela to French Guiana, the Amazons, E. Peru, Bolivia and Motto Grosso, the type from Surinam.

iiea. 
S. geminilinea Prout, (10 f). Considerably smaller than plumbeostrota, rather less brightly coloured, geminili- 
the hindwing similar, the forewing marked more nearly as in the mitranaria sub-group, but with the median 
line double throughout. Rio Madeira (loc. tvp.), Lower Amazon and E. Bolivia. 
S. syssema sp. n. (10 f). Near the two preceding, especially to geminilinea. Hindwing with a broad syssema. 
distal area throughout concolorous with the forewing. Forewing with antemedian line more direct, central 
group of lines more complicated even than in geminilinea, apical patch entirely of the ground-colour. Muzo, 
Colombia, 400—800 m (A. H. Fassl), 1 in coll. British Museum. 
S. mitranaria Walk. (10 g). This species and the two following have scarcely any clouding on the fore- mitranaria. 
wing, but the thick subapical line (from costa to termen just behind the 3rd radial), which begins to appear 
in plumbeostrota (lOf), becomes a very pronounced feature, mitranaria is somewhat variable, but readily known 
by its straw-yellow forewing, sharply contrasting hindwing with unusually large cell-mark, etc. “Brazil” 
(Amazon?), also known to me from Cayenne and S. E. Peru. 
S. simplicilinea Prout (10 g). Colouring of geminilinea, or with the ochreous parts almost as reddish 
as in plumbeostrota. Distinguishable from the former by its single median line, from the latter by its smaller 
size and much more simply marked fore wing. E. Bolivia (type) and E. Peru. 
simplicili- 
nea. 
S. scriptilinea Schaus (10 g). Nearest to mitranaria, the lines of the forewing not so extremely oblique scriptilinea. 
anteriorly, the hindwing with much less sharp contrasts, less large cell-spot, etc. Costa Rica (type); forms (?) 
in Venezuela and on the Lower Amazon. 
S. purpureoplaga Prout (10 g). Very distinct in the strongly rounded costa of forewing and little rounded purpureo- 
termen of hindwing. The olivaceous upperside and red underside recall Dithecodes, but on account of the ex- plaga. 
tremely aborted hindtarsus of the <$ it is better referred here; the hindtibia is rather long, with hair-pencil. 
Only known from the Amazon. 
S. prasinotribes sp. n. (10 f). Close to purpureoplaga, including the structure, red underside and bright prasinotri- 
red face. A little smaller, the shape slightly less extreme, the cell-marks punctiform; both wings above deep hes - 
vinaceous-grey, with only a band between median and postmedian greenish; median somewhat less sinuous 
than in purpureoplaga. Taperinha, near Santarem, 21— 31 July 1927 (Dr. H. Zerny), type in Museum Wien 
S. pallida Warr. (10 g) is still more like a Dithecodes (p. 72), but the C has 4 well-developed spurs. Underside pallida. 
red. As only the type is known (“Amazon, Bates") it is by no means impossible that it may prove to be the 
$ to incurvaria Guen (10 h). 
S. discors Prout (10 g). Very similar to the preceding, but with the postmedian line of the forewing discors. 
more distallv placed, more sinuous and denticulate, the median line likewise as a rule somewhat further from 
the cell-dot. As the has not the wing-specialisation of incurvaria, this is certainly a separate species though 
nearly related. The type is said to come from Bogota, but as the rest of the material known to me is from 
French Guiana and the Amazon it is permissible to suspect an error in labelling. 
S. incurvaria Guen. (10 g). Remarkable for the distorted border of the hindwing and its dull rosy fringes; incurvaria. 
also for the clothing of this wing beneath with dense hairs. As in the allies, the underside is wholly red. "Brazil” 
(? Amazon).
