Type of genus: T. denlata Schs. 
T. dentata Schs. (143 b). Exterior somewhat like that of P. disjuncta, but smaller and darker brown, dentatu. 
the whole basal half of the costal margin black, more reddish-brown distally. Hind wing brown. Brazil (Rio 
de Janeiro). 
T. cayuga Schs. has dark brown forewings strewn with blue and traversed by numerous black undulate cayuga. 
lines which are broad light brown at the inner margin and in the apical half of the costal margin, the black 
undulate lines on this light area are likewise only somewhat darker than the ground; black spots before the 
centre and at the lower cell-end, and a dark streak below the middle radial branch to the undulate line. Hind¬ 
wing dark greyish brown. Expanse of wings: 46 mm. Guatemala. 
T. noctuidiformis Dogn. ( = cossula Rothsch.) (143 b) deviates somewhat from the diagnose of the noctuidi- 
genus, since the antennae are only finely ciliated, the legs more thickly haired, vein 5 of forewing arises a little formis. 
below the upper cell-angle. Forewing brown, strewn lighter and mixed with yellowish in some places, with a 
light, strongly dentate anterior transverse line which is partly bordered with black, and a broad black post¬ 
median line bordered with light on both sides and extending from the costal margin almost straight to the 
anal angle; a light-centred cliscal spot at the cell-end is encircled with black; instead of the undulate line there 
are light small spots partly shaded with black inside, an irregular black marginal line behind them. Hindwing 
white, brownish at the margin. Peru. 
5. Genus: Dyasia Schs. 
This genus has much shorter palpi, the last joint being entirely hidden in the hair. antennae tufteclly 
ciliated. Wings short and broad; vein 6 of forewing arises from the centre of the accessory cell, the two lower 
subcostal branches arise not stalked from the end of this cell. Hind wing almost like that of G alledema. The 
are much larger. 
Type of genus: D. viviana Schs. 
D. viviana Schs. (143 b). Basal third of forewing whitish, scantily strewn with brown, reddish yellowish viviana. 
brown in the median area, the distal margin lilac with velvety brown spots in it, the two former colours defined 
by a curved black line; a yellowish-white spot at the cell-end encloses a reniform macula which is surrounded 
with brown; the posterior transverse line is steel-grey, deeply dentate, a brown dentate line behind it, and 
yellowish-white vein-spots. Hindwing white with a brown marginal line. The violettish-grey marginal colour 
extends to the median area in some specimens. French Guiana. 
D. juvencula Dogn. Base of inner margin, interior area and marginal area of forewdng whitish, scantily juvencula. 
strewn with brown, the rest, also the inner margin, more intensely brownish, with a blackish-brown apical 
spot and chocolate-brown transverse lines, the anterior ones pointedly broken basad in the cell, in the shape 
of the point of a lance, the posterior one double, filled with white and more intensely marked in some places. 
Hindwing white, brownish on the veins and at the margin. Expanse of wings: 29 mm. Amazons. 
D. punctata Rothsch. (143 c) has brownish forewings dusted with lilac pink, with 2 broad brown punctata. 
shadowy bands and brown irroration; transverse lines composed of small round black spots of various sizes; 
2 large black subapical spots. Hinclwing light brown, darkened at the margin. Amazons. 
D. stigmatica Rothsch. (143 c). Fore wing sooty brown with a purple tint, rusty brown in the basal stigmatica. 
third and streaked black, a broad red-brown, black-spotted antemedian band; these striae are very scanty 
in the two marginal thirds, a postmedian row of small red-brown, black-centred spots, a large rusty red sub- 
apical spot encloses a broad blackish-brown band. The whitish hindwing is slightly tinged grey at the margins. 
Amazons. 
6. Genus : Antiora Wkr. 
Only one species with broad wings; A antennae pectinated. Vein 5 of fore wing arises from the centre 
of the cross-vein, 6 from the upper cell-angle, the 4 lowest subcostal branches on a joint stalk from the end 
of the accessory cell. 3 of hindwing stalked with 4, and 6 with 7, 5 arises near the upper cell-angle. 
Type of genus: A. subfulva Wkr. 
A. subfulva Wkr. (= ochromixta H.-Schaff.) (143 c) is sexually very dimorphous, the A small with subfulva. 
narrow wings, the $ very robust; both are similarly coloured and marked, ash-grey, finely strewn white and 
orange, with black notched transverse lines and a whitish discal luna; the whitish sinuate undulate line is 
shaded darker inside. Hindwing light grey, the <$ blackish and thinly scaled. Brazil. 
7. Genus: Amirocampa H.-Schaff. 
The typical representative of the genus is presumably the largest Notodontid known, a somewhat 
smaller species was described of late beside it. It chiefly differs from the preceding genus in the non-stalked
