SORYGAZA. 
Sorygaza, Walker, Cat. xxxiv. p. 1181 (1865). 
This genus was founded by Walker on the male of a Venezuelan insect. Numerous 
species are here added to it from Central America, where Walker’s species, 8. didymata, 
also occurs. | 
1. Sorygaza didymata. (Tab. XL. fig. 24.) 
Sorygaza didymata, Walk. Cat. xxxiv. p. 1181 (¢)’. 
Hab. Panama, Chiriqui (Ride, in mus. Staudinger).—VENEZUELA!, 
The specimens from Chiriqui in Dr. Staudinger’s collection are almost identical with 
Walker's type, which is now in the Oxford Museum. | 
2. Sorygaza area, sp.n. (Tab. XL. fig. 25, 2.) 
Female. Primaries and secondaries pure white; the primaries crossed about the middle by a rather wide waved 
brown band, and with a small brown spot at the base and one on the costal margin close to the apex ; the 
secondaries irrorated with brown scales at the apex and round the outer margin; the underside white, 
very thickly irrorated with brown scales: head, thorax, abdomen, and legs white, the palpi and antenne 
pale brown. Expanse # inch. 
Hab. Panama, Chiriqui (Ribbe, in mus. Staudinger). 
This little species is allied to S. didymata, Walk., but it is very different in colour 
and markings. 
3. Sorygaza mardia, sp.n. (Tab. XL. fig. 26, 2.) 
Female. Primaries pale grey, crossed from the costal to the inner margin by two dark brown lines—the first 
near the base, the second about the middle,—beyond which are two very indistinct waved whitish lines, 
the fringe pale grey; secondaries pale grey, but rather darker than the primaries, partly crossed below 
the middle by an indistinct whitish line ; the underside pale greyish-brown, slightly irrorated with darker 
brown scales: head, thorax, abdomen, and legs pale grey, the antenne and palpi dark grey. Expanse 
? inch. 
Hab. Panama, Chiriqui (Ridbe, in mus. Staudinger). 
One specimen. 
4, Sorygaza arbela, sp. n. (Tab. XL. fig. 27, 2.) 
Female. Primaries white, crossed about the middle from the costal to the inner margin by a wide brown band 
edged on both sides with a fine waved black line, and with several indistinct brown markings near the 
apex and along the outer margin, the marginal line with black points, the fringe pale brown; secondaries 
pale brownish-white, paler at the base, two white lines partly crossing the wing from the anal angle; the 
underside of both wings white, thickly irrorated with brown scales: head, thorax, abdomen, and legs pale 
brownish-white, the antennz and palpi pale brown. Expanse 2? inch. 
Hab. Panama, Chiriqui (Ribbe, in mus. Staudinger). 
A very distinct species. The primaries are slightly rounded on the outer margin. 
5. Sorygaza armasata, sp. n. (Tab. XL. fig. 28, 2.) 
Female. Primaries cream-colour, crossed from the costal to the inner margin beyond the middle by a narrow 
pale yellowish-brown band, beyond which is a submarginal waved white line partly edged on the inner
