HETEROCERA. 531 
ANISOPERAS (to follow the genus Hygrochroma, II. p. 60). 
Anisoperas, Warren, Novit. Zool. ii. p. 187 (1895). 
1. Anisoperas subfulvata. (Tab. XCVIII. fig. 11.) 
Anisoperas subfulvata, Warren, Novit. Zool. iv. p. 487 (1897) °. 
Hab. Guatemata, Volcan de Atitlan 2500 to 3500 feet (Champion); Costa Rica, 
Candelaria Mts. (Underwood '). 
We figure a Guatemalan specimen, which is a little more brightly coloured than 
the type. 
2. Anisoperas catops, sp.n. (Tab. XOVIII. fig. 14, ¢.) 
Male. Primaries and secondaries dark brown, with a yellowish shade about the middle of both wings ; the 
primaries crossed about the centre from the costal to the inner margin by two darker brown lines, and 
with an indistinct greyish-brown spot at the apex; the secondaries crossed below the middle by a narrow 
dark brown line, which extends from the costal margin near the apex to the middle of the inner margin, 
and with several very indistinct brown spots near the anal angle; the fringe dark brown; the underside 
of both wings bright brownish-yellow, with the lines much more distinct than above, the outer margins 
greyish-brown: head, antenne, thorax, and abdomen dark brown above, brownish-yellow beneath. 
Expanse 13 inch. 
Hab. Costa Rica, Candelaria Mts. (Underwood), Volcan de Irazu 6000 feet (Rogers). 
This species is allied to A. subfulvata, Warr. 
3. Anisoperas dolens, sp.n. (Tab. XCVIII. fig. 15, ¢ .) 
Male. Primaries and secondaries dark greyish-brown; the primaries crossed from the costal to the inner 
~~ margin by two waved darker brown lines—the first near the base, the second beyond the middle,—and 
with a faint submarginal waved line extending from near the apex to the anal angle; the secondaries 
crossed below the middle by a waved brown line, and with the submarginal line very indistinct ; the 
fringe dark brown; the underside of both wings dull greyish-brown, with the lines very indistinct : 
head, antennew, thorax, abdomen, and legs greyish-brown. Expanse 1,8, inch. 
Hab. Mexico, Cordova (Riimeli), Jalapa (coll. Schaus); GuatTeMaLa, Las Mercedes, 
San Isidro, Volcan de Atitlan, Zapote, Senahu (Champion); Costa Rica, Volcan de 
Trazu 6000 feet (Rogers); Panama, Chiriqui (Ade), Volcan de Chiriqui 4000 feet 
(Champion), Panama city (J. J. Walker). | 
Varies considerably, both in colour and in the distinctness of the markings. We 
figure a male from Zapote. 
4, Anisoperas lurida, sp. n. (Tab. XCVIII. fig. 16, 3 .) 
Male. Primaries and secondaries greyish-brown ; the primaries crossed from the costal to the inner margin by 
two darker brown lines, edged with grey—the first near the base, almost straight, the second beyond the 
middle, much curved from the apex to the anal angle,—and with a zigzag indistinct submarginal line 
extending from the apex to the anal angle, the fringe dark brown; the secondaries crossed about the 
middle from the costal margin to the anal angle by a narrow dark brown line, which is edged on the 
outer side with greyish-white scales, and with a marginal row of very small white dots extending from
