2. Metanema bonadea, sp.n. (Tab. XLVIL figg. 22,3; 23, 2.) 
Male. Primaries and secondaries pale fawn-colour ; the primaries crossed near the base by a slightly curved 
brown line, and with a large angular dark brown mark near the apex extending partly across from the 
costal margin, a small black dot at the end of the cell; the secondaries crossed beyond the middle by a 
faint brown line; the fringe pale fawn-colour; the underside very much as above, but without the brown 
mark on the primaries : head, thorax, abdomen, antenns, and legs pale fawn-colour.—Female. Primaries 
with the brown mark not nearly so dark or so well-defined, a brown line edged with white near the apex, 
crossing the wing to the inner margin, and a marginal waved white line extending from the apex to the 
anal angle. Expanse, d 1%, 9 14 inch. 
Hab. Guatemata, Las Mercedes 3000 feet (Champion). 
Varies slightly in colour, one of the males being very much paler than the speci- 
men of that sex figured. 
3 Metanema neon, sp. n. (Tab. XLVII. figg. 24,4; 25, 2.) 
Male. Primaries and secondaries pale yellowish-brown, almost yellow in the middle; the primaries crossed 
from the costal margin by two very faint brown lines—the first near the base, the second beyond the 
middle and extending from the apex to the inner margin,—and with a grey spot close to the apex and a 
plack dot at the end of the cell; the secondaries very similarly marked; the underside pale greyish- 
brown, irrorated with darker scales : head, thorax, abdomen, antenna, and legs pale brown. The female 
with the primaries and secondaries very pale brown, both wings crossed by indistinct brown lines and 
with a black spot at the end of the cell. Expanse, ¢ @, 14 inch. 
Hab. Guaremata, Las Mercedes, Volcan de Atitlan 2500 to 8500 feet, Pantaleon 
1700 feet, San Gerénimo (Champion). 
The females vary in the distinctness of the markings; in some specimens they are 
almost black, in others very faint. 
4. Metanema brea, sp.n. (Tab. XLVII. fig. 26, 3.) 
Male. Primaries and secondaries reddish-fawn-colour, thickly irrorated with yellow ; the primaries crossed 
from the costal to the inner margin by two narrow brown lines—the first near the base, edged on the. 
inner side with greyish-white, the second just beyond the cell, edged on the outer side with greyish- 
white,—and with a large pale yellow mark at the apex and a smaller one at the anal angle; the second- 
aries crossed about the middle from the costal to the inner margin by a narrow brown line, which is 
edged on the outer side with greyish-white, and with a large yellowish patch—divided into two by a 
reddish waved line—at the apex extending partly along the outer margin, and a small yellow spot at the 
anal angle ; the underside pale reddish-yellow, marked very much as above, but more indistinctly : head, 
thorax, abdomen, antenne, and legs fawn-colour. Expanse 13 inch. 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
One specimen. 
MYCHONIA. 
Mychonia, Herrich-Schiaffer, Samml. aussereur. Schmett. pp. 63, 83 (1850-58). 
The type of this genus is M. corticinaria, Herr.-Schaff., from Brazil. I refer to it, 
with some doubt, two species from Central America.
