dominantly rosy, with an admixture of drab, especially along costal margin of forewing and with characte¬ 
ristic yellow suffusion about the double white cell-dots; fringes yellow. Mexico. 
T. auctidisca Prout. Rather smaller and shorter-winged than subplumbea (9 d), with broader purple- auctidisca. 
red margins, cell-mark of forewing large and white (transversely oblong), fringe of forewing beneath red in 
posterior part. Maroni River. 
T. subplumbea Bcistelb. (9 d) is named from the deep leaden-grey underside, on which the cell-spots subplum- 
are larger than above, the fringes yellow. Coroico, Bolivia. hea - 
T. flavimargo Warr. (9 d), together with auctidisca , subplumbea and several species which follow, has flavimargo. 
the forewing rather strongly rounded and appearing still more so on account of the anterior curve of the dark 
colour, which leaves the apex as well as the fringe yellow. Cell-mark of forewing tinged with yellow, lunular 
or slightly angled, that of hindwing consisting of 2 minute white spots. Cananche, Cundinamarca, Colombia. 
T. gibbimargo Prout. Larger and darker than flavimargo, with distal margin of forewing still more gibbimargo. 
convex; cell-mark of hindwing a yellow streak. Maroni River. 
T. commixta Warr. (9 e). A beautiful species, with the variegated rosy and orange-red parts sepa- commixia. 
rated from the yellow bordering by a band of olive-grey, which colour also suffuses the bases. Fairly common 
locally in E. and S. E. Peru; known also from E. Bolivia. 
T. cambogiata Warr. (9 e). Ground-colour yellow, with very little of the rose-coloured admixture, cambogiata. 
the grey parts more purplish than those of commixta and including a broad, irregular band outside the cell. 
British Guiana (type), Venezuela, Trinidad and Fonteboa. 
T. citrinaria Warr. (9 e). Similar to cambogiata (possibly a form thereof), but with the basal and post- citrinaria. 
cliscal grey patches more strongly confluent, the yellow subterminal band on both wings broader, cleaner, more 
distally placed, etc. S. E. Peru (loc. typ.) and Ecuador. — grisescens Prout, from Fonteboa, Upper Amazons, grisescens. 
has the grey suffusions still stronger, almost suppressing (even on the hindwing) the rosy admixture. Also 
known from French Guiana. 
T. carnaria H.-Sch. (= laciniata Warr.) (9 e) is best recognized by the dentate yellow subterminal camaria. 
and terminal lines on the rosy ground. Surinam (Herrich-Schaeffer) and S. E. Peru (Warren). 
T. allotmeta Prout (9 e). Darker, the outer yellow line finer, less dentate, more proximally placed, allotmeta. 
especially on the hindwing, where it runs straight across the wing from the 1st radial to the abdominal margin. 
Carabaya, S. E. Peru. 
T. flavicurvata Dogn. is unknown to me, but according to the description differs chiefly from allot- flavicurva- 
meta in the cell-marks, which are about as in auctidisca', the subterminal line of the forewing emits 3 points ia - 
proximad between the 2nd ra.dial and the fold and the apical region, as well as the fringe, is yellow. Bolivia: 
Coroico, 1800 m, 1 <J. 
T. flavifigurata Prout (9 e). Distinguished by the angled forewing (at and just in front of the 1st median) fiavifigu- 
and by the complex yellow cell-mark of the hindwings. Carabaya, S. E. Peru. rata. 
T. devigescens Prout (9 e). By the hindwing, this might almost be taken for a melanic form of car- devigescens. 
naria, but the subterminal line of the forewing is posteriorly farther from the apex and from the 1st median 
forward is lost in a cartridge-buff apical patch which becomes costally suffused with the ground-colour (upper- 
side) or with a dull reddish orange (underside). Surinam (type) and S. E. Peru. 
T. benevisio Prout (9 e). Very similar to a small gavisata (9f), but suffused with purple-grey almost benevisio. 
throughout, the cell-dots of the forewing reduced and yellowish, the terminal yellow borders very narrow but 
almost complete, only interrupted about the 1st median and not widening apically. Buenavista, E. Bolivia, 
750 m, January—April 1907 (J. Steinbach), 2 <$$ hi coll. Tring Museum. 
T. gavisata Walk. (9 f). A well-known species, yellow, generally (though not invariably) very heavily gavisata. 
suffused with orange-red and with several wavy red, or in part purplish, lines. Cell-marks white, geminate 
on both wings. Described from the Amazons, but distributed to Costa Rica, French Guiana and Peru, south¬ 
ward to Matto Grosso. 
T. brunneomarginata Warr. (9 f). Much paler, the terminal line band-like, brown-grey, the posterior brunneo- 
cell-dot of each wing enlarged. French Guiana; also known from Surinam and N. E. Brazil. Possibly a race rnargmata. 
of the following. 
T. decorata Warr. Similar to the preceding but with much additional brown-grey clouding, namely decorata. 
on the forewing about the cell-spots and in a broad longitudinal streak thence to mid-termen, on the hindwing
