A. luteilinea Drc. (154 g) has purple brown forewings broadly mixed with yellowish-green, with double 
dentate grey transverse lines, a large black spot at the cell-end and 3 black apical spots; 2 white dots above 
the anal angle. Hindwing yellowish-white, with dark brown veins and a black anal spot, fringe yellowish- 
green. Peru, Bolivia. 
A. dyari Schs. (154 g) is very similar to luteilinea ; forewing dark lilac grey, mixed with green at the 
costal margin, whitish at the inner margin with green and olive brown markings, apex and anal angle whitish, 
strewn with green, the transverse lines as in luteilinea, with a green and reddish-brown mixture below the cell; 
a velvety blackish-brown lunar spot at the cell-end; the fine double postmedian line is reddish-brown, small 
blackish-brown spots are subapical. Hindwing white strewn with blackish-brown, most densely so at the mar¬ 
gin, with an indistinct white postmedian line and a dark anal spot. Costa Rica. 
121. Genus: Marcella Dogn. 
Closely allied to Naprepa anatomically, but the $ antennae are pectinated long, the pectinations ciliated, 
the palpi much shorter; the costal vein of the hindwing arises only behind the centre of the cell. The subcostal 
branches of the forewing are as in Azaxia. Only 1 species has been described. 
Type of genus: M. volcancita Dogn. 
M. volcancita Dogn. Forewing reddish yellowish-brown, strewn with red-brown on the two first sub¬ 
costal thirds, the veins and the inner margin, strewn with green below the median vein and before the apex, 
the cell blackened, mixed with green at the end; a faded black median line forms an angle postdiscally, a black 
stripe is at the cell-end; the dentate postmedian line is indistinct, black internerval dots are behind it, 
2 postcellular dots are thicker; the ends of the veins are strewn with white. Hindwing yellowish red-brown, 
darker at the margins, with a blackish-brown anal spot. Expanse of wings: 50 mm. Colombia (Quindiu). 
122. Genus: Odontosia Him. 
This genus which is distributed also in the palaearctic regions (cf. Vol. II, p. 305) has the antennae 
pectinated to the ends, short palpi, rather long fore wings with a dentate oblique margin, a strong scale-dent 
at the inner margin, none of the subcostal branches stalked. Thorax without a tuft. Only 2 American species. 
Type of genus: 0 . carmelita Esp. from Europe. 
0. elegans Stkr. (154 g). Forewing brown, darkened in the costal-marginal area, without transverse 
lines, with a silvery white basal ray along the inner-marginal vein. Hindwing light yellowish, with a large 
brown anal spot below which the inner-margin is yellowish; 2 or 3 black internerval streaks are subapical. 
From Canada to the Rocky Mts. f. grisea Stkr. (= notaria Edw.) is a more ash-grey form from Colorado. 
0. viridifusca Schs. differs from the diagnose of the genus in the almost entire-margined, not dentate 
margin, otherwise the same. Forewing moss-green, broadly violettish-brown at the inner margin, with simi¬ 
lar costal-marginal spots from which the distinct transverse lines proceed, the posterior one with white vein- 
spots; grey dentate shadows are behind the grey cell and before the postmedian line; black double dots at 
the margin are centred white above the anal angle; the centre of the distal margin is dusted reddish-brown. 
Hindwing blackish-brown with a black and white anal spot. Expanse of wings: 35 mm. British Guiana. 
123. Genus: Dottia Schs. 
Separated from Odontosia by the antennae not being pectinated to the tips, and by the doubly 
split anal tuft; the costal vein of the hindwing arises near the cell-end. Only 2 species. 
Type of genus:: effecta Schs. 
D. effecta Schs. (154 g). Forewing red-brown, dusted with violet as far as the fine double dentate 
postmedian line, with a light green basal ray as far as the double dark brown anterior transverse line at 
which there is a white dot at the submedian fold; 2 dark stripes extend from the cell-end to the margin; 
the d exhibits a dark-shaded white spot above the anal angle, another one between the veins 4 and 5. Hind¬ 
wing blackish-brown. Costa Rica. 
D. boliviata Schs. Anterior body yellowish sand-coloured and brown, abdomen brown. Forewing 
brown in the basal area above, reddish ochreous below the cell, bordered by 2 dark lines; median area 
creamy yellowish as far as the lower cell-angle and along the costal margin to the apex; cross-vein black, 
rusty brown stripes behind it above and below 5, the upper one extending to the margin; 3 indistinct fine 
brown lines behind the cell; cellular branches deep reddish olive, finely bordered with brown towards the 
margin, the marginal area being yellowish mixed with olive; inner margin partly dusted with rusty brown. 
Hindwing smoky brown with a light postmedian shadow. Expanse of wings: 47 mm. Bolivia.
