OPHITIS; MERAGISA. By Dr. M. JDraudt. 905 
91. Genus: Opliftis Fldr. 
Founded upon one species, scarcely different from Gisara ; only separated by the somewhat shorter 
palpi, broader forewings with a somewhat rounder distal margin; no difference in the neuration. 
Type of genus: 0. magnaria Fldr. 
0. magnaria Fldr. (152 h) is a very large blackish-brown insect with a darkened basal part which magnaria. 
is distally bordered by a notched line, a spot like a reniform macula at the cell-end, a notched postmedian line 
behind it, only visible in the discal part; subterminal area somewhat lighter, enclosing a whitish undulate line, 
3 thick black spots before it in the lower half; apex parted by white. Hindwing greyish-brown with a dark 
marginal band. Brazil. 
92. Genus: Meragisa Schs. 
A large genus of very homogeneous insects with densely hairy body and legs, also the second joint 
of the palpus is densely hairy, the last joint very short, hidden in the hair. The male antennae are studded 
with ciliary tufts as in all the preceding genera. Forewing relatively narrow, costal margin somewhat convex 
at the base, distal margin broad, rounded; neuration exactly the same as in Chadisra. Nearly all the species 
have light forewings with notched mostly double transverse lines of a characteristic course. 
Type of genus: M. valdiviesoi Dogn. 
M. valdiviesoi Dogn. (152 h). Forewing greyish-white, the fox-coloured median area bordered by valdiviesoi 
double black transverse lines, the anterior line oblique to the centre of the inner margin, the posterior line 
arising shortly before the apex, extending to the anal angle in two flat distally concave bows; a fine black 
crescentiform line before the margin, the lower half of which is as usual scalariform. Hindwing yellowish with 
a broad brownish-grey marginal band and a median shadow before it. Ecuador. 
M. boliviana Dogn. is very closely allied, the forewing somewhat more intensely strewn with black, boliviana. 
the anterior transverse line less oblique and less dentate, the distal line less distinct and more irregular than 
in valdiviesoi, only 4 mm distant from the anterior line at the inner margin, the median area more red-brown 
with a violet tinge. Expanse of wings: 53 mm. Bolivia. 
M. semifulva Drc. Forewing greyish-white, the transverse lines red-brown, dusted with yellow basally semifulva. 
and in the median area, with a yellow spot at the cell-end, a submarginal row of black spots. Hindwing blackish- 
brown with yellow inner margin and fringe. Expanse of wings: 57 mm. Peru. 
M. simeona Schs. is somewhat similar to boliviana by the brown-strewn median area; the same strewing simeona. 
is below the base of the cell; wings white, dusted with brownish cinnamon at the inner margin in the basal 
two thirds; the thick double anterior transverse line is chestnut-brown, finely dentate, the posterior line very 
indistinct and fine; a fine blackish-brown line bordered with white is at the cross-vein; small orange cinnamon 
spots behind the blackish-brown subterminal line, a curved black line at the margin. Hindwing brownish 
sand-coloured with a light reddish-yellow inner margin and white fringe. Expanse of wings: 45 mm. Monte 
Tolima, Colombia (Quindiu Pass). 
M. siavina Schs. Forewing grey strewn with brown, the usual double transverse lines are brown, with siavina. 
a dark cell-end streak bordered with white. Hindwing dull blackish-brown, inner margin and fringe yellowish- 
white. The $ shows the transverse lines and the distal half of the median area filled with brown, the hindwing 
with brown hair at the inner margin. Expanse of wings: S 55, $ 58 mm. Costa Rica. 
M. medionigra Dogn. Forewing grey strewn with red-brown in the basal area, at the costal margin medionigra 
and in the marginal area, the median area is black with a still darker cell-end streak in it, bordered by double 
transverse lines. Hindwing blackish, yellowish at the inner margin and fringe. Expanse of wings: 47- 48 mm. 
Colombia. 
M. cloacina Dogn. (152 g) introduces a group of very similar species which are difficult to separate; cloacina. 
forewing white strewn with grey, with double black transverse lines and a black cell-end streak. Hindwing 
blackish, yellowish hair at the inner margin, fringe white. Colombia, Ecuador, Peru. 
M. salvina Schs. is near pallida and cloacina, but not so purely white because of the brown strewing salvina. 
of the white forewdng; the extreme costal margin is reddish-yellow, the subbasal line yellow, scaled brown 
distally, both the double reddish-brown transverse lines filled with yellowish, the anterior line interrupted distally 
in the cell; a dark median line from the costal margin to the median vein, bordered wdth yellow outside at the 
cross-vein. Hindwing brownish sand-coloured with a reddish-yellow inner margin and white fringe. Abdomen 
reddish-cinnamon basally. Expanse of wings: 54 mm. Guatemala (Cayuga). 
M. vistara Schs. is also similar; larger, forewing silvery white strewn with reddish-brown; the double vistara. 
black transverse lines are filled with reddish olive like the subbasal line which is double at the costal margin; 
a white spot at the cross-vein with a black and reddish-yellow line, a fine dark line above it at the costal
