rounded-edged, in the type not containing a light spot; apical of the hindwing also more rounded-edged than 
in the allies; cell-spot enlarged on the forewing only. E. Peru. 
R. distinguenda Dogn. (4 c) combines the posterior markings of fallax with a subapical spot darker dwlingu- 
than that of semiornata ; underside nearly as in typical semiornata. Colombia: Canon de Tolima, Quindiu '' 11,1,1 ■ 
and Cauca. 
R. fallax Warr. (5 b) differs from semiornata chiefly in its variegated terminal spots, which are strongly fallax. 
dark at thei redges and along the veins, pale or whitish internally. Pectinations slightly shorter than in semi¬ 
ornata, but scarcely as in trianteris (4 c). The typical form is from S. E. Peru and reaches Bolivia. — allotaxis alloiaxis. 
subsp. nov. (4 c) has the subapical blotch on both wings decidedly shallower, the posterior blotch of the forewing 
longer. Colombia: Muzo, 400—800 m (Fassl), 5 ; type in coll. L. B. Prout. — cohibita subsp. (? sp.) nov. cohibita. 
(4 b). Face and palpus much more mixed with blackish. Cell-dots and terminal markings reduced, the apical 
much less mixed with white than in the other Colombian form, the tornal of both wings obsolete beneath. 
Upper Rio Negro, E. Colombia, 800 m (Fassl), 3 1 $; type in coll. L. B. Prout. Differs from distinguenda 
(4 c) in the less rounded termen of the fore wing and the less large, less dark apical markings. 
R. excelsa Dogn. (6 i) differs chiefly from fallax cohibita (4 b) in having the 2nd abdominal spot ochraceous- excelsa. 
buff, scarcely crested, the apical patch of the hindwing divided into 3 small buff, red-brown-edged spots, the 
cell-spots somewhat larger, the subapical patch of the forewing dark, between the 4th and the 5th subcostal 
narrow, between this and the 2nd radial much broader. Colombia: Alto de las Cruces, Cali, 2200 m. 
R. luteifimbria Dogn. is also near fallax. Rather smaller. “Face yellow and brown.” Palpus brown, luteifim- 
Wings with the cell-dots above large, pale-centred; subapical spot quite narrow, only present between 5th &ria • 
subcostal and 2nd radial, tornal still smaller, yellow bordered with ferruginous brown. Underside with the 
subapical spots present. S. Colombia: Popayan. 
R. porcius Schaus (4 c) has the terminal markings much more extended than in fallax, cell-spot large porcius. 
on both wings. Face and palpus red-brown. Pectinations as lcng as in semiornata. Costa Rica (loc. typ.) and 
Panama. 
R. pelops sp. n. (4 cl) has nearly the coloration and structure of porcius. Pectinations a little shorter, pelops. 
Hindtibial process short. Very distinct in the nearly black face and palpus (except its base), small cell-dots 
reduced anterior border of forewing and especially in the long central projection of the border on both wings. 
I do not think it can be a form of trianteris, the only other of the group in which there is a central projec¬ 
tion. Espiritu Santo, Brazil, 3 September 1920 (Zikan). Type in coll. Seitz. 
R. syncrasis Prout { — conflua Warr., nom. praeocc.). Face and palpus red-brown. Cell-spots nearly syncrasis. 
as in psittacina (4 c), but that of the forewing placed at the posterior end of the discocellulars and preceded 
by a larger, greyer one; apical blotch larger than that of psittacina , crossing the 3rd radial, posterior one 
reduced, especially on hindwing. Underside characterized by the addition of a broad submarginal band on 
the forewing, faintly continued on the hindwing, where the anal spot is absent. E. Peru, with psittacina. 
R. brunneilinea Warr. (4 d). Smaller. Face nearly as in psittacina, terminal blotches more irregular brunnei- 
in shape. Unmistakable through the brown hindmarginal streaks, from which arise rows of brown vein-dots, 
representing the two lines. Described from S. E. Peru, known also from Colombia, Bolivia and the Amazons. 
R. lafayaria Dogn. (4 c). Dognlns type from Loja has never been quite matched. The Tring Museum lafayaria. 
has, however, received 2 <3$ from Baeza, E. Ecuador (one of them here figured), which scarcely differ excejit 
in their rather smaller size. The smaller cell-spot and some differences in maculation separate it from promon- 
toria, which is, however, probably only a race. — promontoria Warr. (5 g) has the posterior patch darkened promontcria. 
behind the cell, separated from the paler distal part by a curved postmedian line. Carabaya. Also a series from 
Cochabamba (Bolivia) in the United States National Museum, where it bears the manuscript name of la¬ 
fayaria peruviana. — dilata Prout (4 c) has the patch at middle of hindmargin a little darker still and con- diiata. 
siderablv enlarged. E. Peru: Huancabamba (Cerro de Pasco) and Cushi. 
R. lugentiscripta Prout (5 g). Shorter-winged than the preceding and with the antennal pectinations lugenli- 
rather shorter. All the markings darker, the central and posterior more extended. Colombia. — dubia Prout, 
founded on a single <$ from Intaj, Ecuador, has the markings rather more red (though still much darker than 
in dilata [4 c]), on the forewing formed as in lugentiscripta, on the hindwing above with the anal blotch ex¬ 
tended along abdominal margin to y 3 from base, beneath entirely wanting. 
R. latimarginaria Mssn. (5 i) does not fall quite naturally into either of our groups, but may best be latimargi- 
placed here. Palpus similar. Pectinations short. Hindtibial process very short. Abdominal maculation very narta - 
slight, only with attention whitish spots are discernible on first 2 segments. Underside pale, with indefinite 
subapical shading. Peru: Pucatambo to Rio Negro (Amazonas), only the type o known. Possibly a Phrudo- 
centra.
