in a very ample central suffusion between the 1st and the 3rd red line and a slight longitudinal extension 
about the radials connecting this with the very broad border. Rio Cayapas, N. W. Ecuador, only the type known. 
T. subnexa sp. n. (9 f). Size of a small brunneomarginata , but darker, the white being almost confined 
to the central spot and some streaks on the veins. Hindwing with distal margin more bent. Dark cloudings 
on forewing ample. Cell-spots very characteristic, the posterior one on each wing much produced longitudinally, 
the anterior on the hindwing narrowly connected with it, on the forewing forming a separate dot. Probably 
near quadrigata (9 c) notwithstandig the differently shaped wings. St. Jean de Maroni, French Guiana, the 
type <$ in Tring Museum; a rather worn J from La Oroya, S. E. Peru, in the same collection, perhaps differing 
racially. 
T. oeno Druce (9 f), founded on a $ from Jalapa in the Schaus collection, is unknown to me, but should 
be readily recognizable from the figure, which we reproduce. Rather large, much clouded, but with a con¬ 
spicuous reddish band within the cell. “Underside pale pinkish grey, with the w r hite spots as above, both wings 
with a faint waved brown submarginal line.” 
T. biguttata Warr. (9 f). Also considerably clouded, considerably smaller than oeno, the apex perhaps 
less produced; characterized by the double cell-spot on each wing. French Guiana. 
T. irregularis sp. n. (9 f). General aspect of biguttata, but in shape approaching -protuberans — forewdng 
bluntly elbowed at 1st median, thence very oblique; red parts rather brighter than in biguttata, dark cloudings 
less heavy; white spots of forewing more contrasted in size, the anterior being very small, the posterior 
somewhat produced outward; the corresponding spot of hindwing remains small (about as in decorata). Lower 
Amazon: Taperinha, near Santarem, August 1927 (Dr. H. Zerny), type $. Upper Amazon: Codajas (S. M. 
Ivlages), a damaged in Tring Museum. 
T. apicata Dogn. “18 mm. Forewing slightly acuminate, hindwing feebly elbowed at vein 4. Rosy, 
broadly washed with blackish grey, the forewing basally, costally, apicaily and liindmarginally, the hindwing 
on the anterior costal half and before the 2nd line; veins yellow in the red spaces. Forewing with 3, hindwing 
with 2 irregular white discal spots, the anterior one of the forewing minute, 3 sinuous and dentate lines, partly 
lost on the dark suffusions.” (Adapted from Dognin.) Corvico, Bolivia, at 1800 m, 1 $. 
T. protuberans Dogn. “19 and 20 mm. Forewing elbowed on vein 3, the margin strongly oblique 
from 3 to the inner angle, straight from 4 to the apex; hindwing elbowed at 3 to 4, the margin oblique from 
3 to the inner angle, which forms a slight projection. Wings above brick-red with 2 white cell-spots, the 
markings black-brown, the veins in part tinged with yellow. Forewing with costa broadly brownish, ante- 
median excurved, twice bent outward, a broad postdiscal shade immediately followed by a postmedian line, 
and a subterminal, both dentate outward, the subterminal in addition with a large black subcostal dot. Hind¬ 
wing with the lines similar, the anal angle becoming brownish, the fringe yellow, interrupted with grey at veins 
3, 4, 6 and 7. Corvico, Bolivia, 1800 m, 2 <$<$.” 
T. flavitomata Prout (9 f) is even more extreme in shape than protuberans and further differs in its 
pale primrose yellow colour and rosy veins and lines, etc. French Guiana: Godebert Maroni, only the type 
known. 
T. ocrisia Druce (9 g), described as “ Ac-idalia (?)”, is clearly a Tricentra, in spite of its shape and simple 
pattern. The white cell-streak of the forewing, “edged with reddish yellow”, does not come out very clearly 
in the figure. Guatemala: San Geronimo. 
T. amibomena Prout (9 g). This species, except in the undivided areole of the forewing, shows a pretty 
definite relationship with commixta (9 d), at least as regards the shape of both wings and of the clear apical 
mark of the forewing. The coloration, however, is quite distinctive, the postmedian line of the forewing less 
sinuous and there are numerous other differences. French Guiana (type), Lower Amazon and Bolivia. 
T. percrocea Warr. (9 g) is rather smaller than amibomena, much less clouded, but with a charact¬ 
eristic dark spot outside the cell of the forewing and a blacker mark on the fringe at the 3rd radial and 1st 
median. French Guiana (type) and S. E. Peru. — supercrocea form. nov. (? sp.) (9 g) lacks the reddish cloud¬ 
ings, as well as the dark mark on the fringe, but has a cloudy line or shade crossing the hindwing. Para 
(Rev. A. M. Moss), the unique type $ in the Tring Museum. 
6. Genus: Semaeopus H.-Sch. 
Palpus short or quite moderate. Antenna of $ pectinate or more often ciliate in fascicles, the cilia 
generally arising from teeth or rudimentary pectinations. Hindfibia of <$ more or less strongly thickened and 
shortened, clothed with strong tufts of hair, spurs nearly always wanting (a strong pair present in inficeta)\
