T. infernalis Schs. (= levana Drc.) (80 c, cl) entirely resembles Tol. celeste on the forewing, but it 
is somewhat larger with more intense and darker greyish-black markings. At once separable by the quite dark 
hindwings. The $ is much smaller, with very narrow and pointed wings, almost black with a reddish reflection, 
with quite indistinct darker markings. Mexico. 
T. vitreus Dogn. (80 e). The has similarly shaped though not quite so pointed wings. Forewing 
hyaline transparent — but presumably loosely scaled in the freshly hatched specimen —, at the base and inner 
margin with long grey hairs, with a black cross-vein streak on the forewing and traces of several whitish transverse 
lines, being mostly more distinct only at the costal margin. Body blackish-grey intermixed with single reddish 
hairs. Merida (Venezuela). $ apparently still unknown. 
T. avita Schs. (80 d) is very closely allied to vitreus and proxima. Body black, shoulders, sides 
of collar, and outer half of patagia as well as a transverse line above on the base of the abdomen are light flesh- 
coloured, also the end of the abdomen beneath. Forewing transparent smoky-grey, finely strewn with blackish, 
in the basal area and along the inner margin scaled; veins fine white, the markings very similar as in proxima, 
the median transverse lines very close together on vein 2 and connected by a white transverse streak. Hindwing 
at the anal margin broadly haired smoky-black. The larger $ is less transparent; expanse of wings: $ 36 mm, 
9 59 mm. Sao Paulo. 
T. proxima Burm. (= argentina Schs.) (80 d) is extraordinarily similar to avita, larger, more robust, 
somewhat more densely scaled, the median lines less close together, not so strongly notched, not connected 
on 2, the grey median area behind them broader, patagia not flesh-coloured, at the base of the abdomen 2 
flesh-coloured pink hair-tufts on each side. Brazil, Argentina. 
T. cinerascens Wkr. (= nigra Schs.) (80 d). The $ is smoky-blackish, body quite black; on the 
forewing the veins are strewn with whitish, towards the apex at the costal margin a few small yellowish-ochreous 
spots, at, the cell-end 2 black dots, and traces of antemedian and subterminal whitish lines. The larger $ is 
loam-coloured grey, the body more brownish, the anal tuft blackish-brown intermixed with single ochreous 
hairs; forewing with indistinct lighter transverse lines, one black dot each in the cell-angles, and a darker 
brownish spot below the cell between 3 and 4, some more darkenings being also in front of the light subterminal 
band on 4 and between 6 and 7. From Venezuela and Guiana. 
T. bella Drc. (80 e) is allied to the preceding species, but it is larger, of a more greyish-brown 
colour, with more distinct linear markings, the darkened spot of the median area below the cell larger, more 
distinctly defined by the border-lines, the veins in the postmedian area partly darkened, also the fringe 
between the veins. Panama. In the Berlin Museum there is a $ of Euglyphis fibra Schs. labelled as §-type 
of bella. Schatis is also of my opinion that the lable must have been mistaken, for the figure in the Biologia 
is too unmistakable as to allow this possibility. 
T. hirtipes Wkr. (= everildis Schs.) (81 d) is likewise similar, smaller, forewing sand-coloured, the 
veins in the postmedian and subterminal areas striped blackish-brown, basal area, the spot below vein 4 likewise 
smoky-blackish as well as a postmedian shadow which is broad at the costal margin and parted by a light 
line; fringe smoky-black. Hindwing similar with reddish-brown veins. Abdomen brown, the 2 last segments 
blackish-brown. Castro (Parana). 
T. pallida Dogn. (80 e), based upon two much flown <3$, in the structure resembles the $ of cinerascens, 
but the hindwing is rounder; wings hyaline, light brownish ochreous with 2 black dots in the cell-end. Sao 
Paulo de Olivenga (Amazons). 
T. synoecura Dyar (80 c) is most closely allied to bella. Wings light fawn-coloured with the same 
markings as bella \ anal hair of $ ochreous-brown with a golden gloss. The is lighter, with much lighter 
hindwings. The larva lives gregariously in nests. Mexico. 
T. jamaicensis Schs. is smaller, more smoky-grey with the same darkenings at the base and below 
the centre of the cell and a brown postmedian shadow which is very broad at the costal margin; the brown 
marginal shadow is narrow, the brown fringe crossed by the light ends of the veins; the distinct light lines 
of the preceding species are quite absent. Hindwing scantily scaled, light smoky-brown, at the distal margin 
the lightest. Body greyish-brown with a blackish anal tuft. Expanse of wings: 40 mm. Jamaica. 
♦ 
T. gracilis Dogn. This .species described from a B has the shape of the <$ of infernalis (80 c). Body 
blackish-brown, forewing with a light subterminal line parallel to the margin and about 2 mm distant from 
it, before that line the wing is blackish-brown, behind it lighter. Hindwing blackish-brown. Rio Tapajoz 
(Amazons). 
T. lusciosa Dogn. is likewise described to be very similar to bella, the ground of the wings scantily scaled, 
light blackish-brown, the markings grey, as in bella, but both the antemedian line as well as the line between 
the postmedian and subterminal lines are absent; between 5 and 6 there is in the subterminal area a blackish
