132 HETEROCERA. 
Central-American specimens are paler in colour than those from Ecuador, and they 
have the lines crossing the wings more distinct.. All the examples before me are paler 
than Moschler’s figure.

The apical portion of the primaries in some specimens is quite pale, in others dark 
brown. I think it quite possible that S. agnitaria will prove to be inseparable from — 
S. gambarina (Cramer), from Surinam ; but I have not any specimens from that locality 
before me for comparison. . 
12. Semiothisa catualda, sp. n. (Tab. LIII. figg. 14, 15.) 
Primaries and secondaries cream-colour, thickly irrorated with pale brown scales; the primaries crossed near 
the base from the costal to the inner margin by two curved faint brown lines, and with a very distinct 
dark brown straight line crossing from the costal margin near the apex to the anal angle, on the inner 
side of which is a row of small dark brown dots, the marginal line dark brown, the fringe cream-colour ; 
the secondaries crossed by two lines—the first, near the base, extending from the costal to the inner 
margin, the second from near the apex to the anal angle, the marginal line with dark brown points, the 
fringe cream-colour ; the underside slightly darker than above, very thickly irrorated with reddish-brown 
scales, both wings crossed from the costal margins by two reddish-brown bands—the first narrow, the 
second wide and very distinct: head, thorax, abdomen, antenne, and legs cream-colour, Expanse 
13 inch. . 
Hab. Panama, Chiriqui (Zrétsch, in mus. Staudinger).

13. Semiothisa ostia, sp. n. (Tab. LIII. fig. 16, ¢.) 
Male. Primaries and secondaries pale fawn-colour slightly irrorated with darker scales, their outer margins 
broadly bordered wich dark reddish-fawn-colour ; the primaries with two dark reddish-brown spots on 
the costal margin, from which two indistinct waved lines cross to the inner margin, and with a narrow 
dark reddish line partly crossing the wing near the apex; the secondaries crossed about the middle by 
an indistinct waved line, which extends from the costal to the inner margin; the fringes of both wings 
pale fawn-colour ; the underside much paler than above, and with the lines more distinct, a rather large 
black spot at the end of the cell on both wings: head, thorax, abdomen, and antenne fawn-colour, paler 
beneath, the legs yellowish-fawn-colour. Expanse 13 inch.
