158 HETEROCERA. 
8. Ischnopteryx rostellaria. 
Syrtodes (?) rostellaria, Feld. & Rogenh. Reise der Novara, Lep. t. 125. fig. 1 (?)?. 
Hab. Mexico 1, Jalapa, Coatepec, Paso de San Juan (coll. Schaus); GuaTEMALa, San 
Gerénimo ( Champion) ; Costa Rica (Van Patten), Volcan de Irazu 6000 to 7000 feet 
(Rogers). 
There are two forms of the female of this species: one like that figured by Felder 
and Rogenhofer !, and another without the white on the primaries, the latter resembling 
the male in colour. 
4. Ischnopteryx velledata. 
Ischnopteryz velledata, Méschl. Verh. zool.-bot. Ges. Wien, 1881, p. 413, t. 18. fig. 25°. | 
Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion) — GUIANA, 
Surinam }, 
Two males have been received from Chiriqui. This species will probably have to be 
removed from Ischnopterye when we know the two sexes. The shape of the hind wing 
in the male is very different from that of any species of the genus known to me. 
5. Ischnopteryx chryses, sp.n. (Tab. LV. figg. 28, 24, ¢; 25, 2.) 
Male. Primaries dark sage-green, thickly irrorated with brown scales, and crossed from the costal to the 
inner margin by two zigzag, fine, reddish-brown lines, a fine waved submarginal white line extending 
from the costal margin to the anal angle and two small black streaks on the inner margin about the 
middle, the marginal line black, the fringe brown ; secondaries black, broadly bordered with yellow at 
the apex; the underside of the primaries chrome-yellow, crossed from the costal to the inner margin by 
two black bands—the first near the base, quite narrow, the second very broad and beyond the middle,— 
and with the apex and fringe fawn-colour, that of the secondaries yellow, with the inner half dusky 
black, and a black band crossing the wing from the costal to the outer margin where it is widest: head, 
thorax, and upperside of the abdomen sage-green, the antenne brown, the underside of the abdomen and 
the legs fawn-colour.—Female. Primaries dark reddish-brown, with the costal and outer margins and 
the apex pale greenish-brown, the white line not so distinct as in the male. Expanse, ¢ 2, 12 inch. 
Hab. Panama, Chiriqui (Trétsch, in mus. Staudinger), Bugaba, Volcan de Chiriqui 
2000 to 3000 feet (Champion). 
A very distinct species, not closely allied to any other known to me. We figure a 
pair from the Volcan de Chiriqui. 
6. Ischnopteryx canopus, sp.n. (Tab. LV. figg. 26, 27, 3.) 
Male. Primaries dark brown, irrorated with green scales, crossed near the base from the costal to the inner 
margin by a green line edged with black, beyond which a black line crosses the wing, a dark brown spot 
on the costal margin near the apex, below which are three small dark brown spots, a fine white line 
partly crossing beyond the middle, the marginal line spotted with black, the fringe dark brown ; 
secondaries brownish-black, with the apical portion bright orange-yellow; the underside of the 
primaries yellow, crossed about the middle from the costal to the inner margin by a rather wide black 
band, the inner margin from the base to the black band dark grey, a large oval black spot near the apex,
