brown, lighter basally, with a fine dark median line edged with light, and a black and white anal spot. 
Expanse of wings: 45 mm. Costa Rica. 
M. ampllissa Drc. (151 f) is a very large species with broad wings, hardly mistakable for any other amphissa. 
because of the whitish-grey forewing being provided with black veins and two sharply notched transverse 
lines, and the yellow, black-ringed abdomen. Colombia, Bolivia. 
M. boettgeri Drc. (151 f). Forewing blackish-brown, traversed by two undulate black tranverse lines, boettgeri. 
behind the cell; a green spot at the cell-end, distal margin and inner margin densely strewn with green scales, 
marginal line black. Hindwing dark brown with light fringe. Eastern Peru. 
M. nigrlviridis Dogn. (151 f) has blackish-brown forewings strewn with dark green along the inner nigriviridis. 
margin, also at the costal and distal margins between the veins which are strewn black and white; a small 
green spot at the cell-end; the black transverse lines are dentate, the anterior one single, the posterior one 
double, the ground behind it lighter. Hindwing blackish, lighter at the base and fringe. Expanse of wings: 
38 mm. Argentina. 
M. taetrica Schs. is somewhat similar to the green species of Disphragis, the moss-green forewing taetrica. 
with a produced anai angle, light violettish-brown at the base of the inner margin and a similar shadow behind 
the cell; the fine black transverse lines are double, the posterior line broken up into double rows of dots, a 
dentate brownish shadow before it around the cell-end to the centre of the inner margin. Hindwing dark brown, 
lighter towards the base and at the inner margin, with a black and white anal spot. Expanse of wings: 36 mm. 
French Guiana. 
81. Genus: Magava Wkr. 
G antennae serrate, with ciliary tufts, which are long in the basal halves; palpi rising, with a hairy 
middle joint and very short terminal joint. Forewing exactly like that of Malocampa , hindwing broader with 
a long-haired inner margin, neuration as in Disphragis, the costal branch proceeds a little behind the centre 
of the cell. Three tropical American species. 
Type of genus: M. multilinea Wkr. 
M. multilinea Wkr. (151 g) is unmistakable for its yellowish-white forewing being alternately tra- multilinea. 
versed by numerous orange and violet transverse lines. Costa Rica to Colombia and Bolivia. 
M. marginata Schs. ( = incurvata Jones). Forewing white, scantily strewn with reddish, more densely marginata. 
at the distal margin, strewn with black at the inner margin, with double bluish-black transverse lines, an oblique 
basal one, a median one which is only double at the costal and inner margins, and a distal one arising near 
the margin before the apex and extending in an inward curve to the inner angle. Hindwing white, finely 
strewn with red-brown, with a long hair-pencil at the inner margin. Expanse of wings: 46 mm. Brazil. 
M. forensis Schs. is very much like marginata , but the hindwing is dark brown with white ends of the forensis. 
fringe; forewing white, strewn with light brown, dark greyish oclme at the base, bordered by the oblique 
double antemedian line; a white streak with a brown dot at the cell-end, from where a feeble brown line ex¬ 
tends to the inner margin; described from Guatemala. 
82. Genus: Thyaua Dogn. 
Very similar to Magava, separated by a raised hair-tuft on the first abdominal segment, long hair of 
the cell on the forewing beneath, and with 3 rows of hair on the subcostal vein, cellular fold and median vein 
of the hindwing beneath; vein 7 of forewing arises from the lower distal angle of the areole, the two next veins 
stalked from the upper angle; the two pairs of veins arising from the cell-angles on the hindwing are stalked, 
the costal vein arises from the distal third of the cell. Only 1 species: 
Th. sumptuosa Dogn. (151 g) resembles a Thyatira in the colour and marking, the brown fore wing sumpluosa. 
exhibiting oval white spots, the longest spot extending from the base of the inner margin almost to the fourth 
fifth and being traversed by 4 transverse lines. Hindwing blackish brown with a white anal spot parted by 
black. Bolivia, A m azons. 
83. Genus : ltliudn Wkr. 
The (J antennae are shorter ciliated than in Thy ana; the distal margin of the long narrow forewing 
is not entire, but feebly dentate, neuration as in Disphragis excepting the costal vein of the hindwing arising 
only shortly before the cell-end. Numerous species partly very difficult to separate have been described.
