PALTHIS.—BERTULA. A4T5 
5. Palthis bizialis. (Tab. XXXIX. figg. 14, 14a, ¢; 15, 2.) 
Bleptina bizialis, Walk. Cat. xix. p. 865 (3) °. 
Hab. Mexico, Atoyac in Vera Cruz, Teapa in Tabasco (H. H. Smith); GUATEMALA, 
Las Mercedes, Cerro Zunil, Volcan de Atitlan 2500 to 3500 feet (Champion) ; Costa 
Rica, Volcan de Irazu 6000 to 7000 feet, Caché (Rogers); Panama, Chiriqui (Ribbe, 
in mus. Staudinger), Volcan de Chiriqui 2000 to 6000 feet (Champion).—Brazit, Rio 
Janeiro 1, 
Mr. Champion captured a large number of specimens of this species at San Agustin, 
on the slope of the Volcan de Atitlan, in December 1880. The type is now in the 
Oxford Museum ; our specimens are almost identical with it. 
NEOPALTHIS, gen. nov. 
Male. Head and eyes small; the thorax rather broad ; the abdomen slender, not extending beyond the wings, 
the anal tuft rather large; the antenne somewhat short and thick, very finely pectinated ; front legs 
small; hind legs elongate and slender, with the spurs long. Palpi with the first joint very small; the 
second joint long, rather flattened, and curved upwards; the third joint ‘about half the length of the 
second, tufted with fine hairs, The primaries long, very pointed at the apex ; the costal margin slightly 
concave about the middle; the outer margin straight, receding to the anal angle; the inner margin 
straight. The secondaries rather broad, rounded at the apex, and slightly angular at the anal angle. 
The female similar to the male, but with the palpi very different in shape, the first two joints projecting 
straight out from the head; the third joint turned upwards and club-shaped, but very finely pointed at 
the tip, thickly clothed with large scales (not hairs). 
Type Neopalthis madates. 
1. Neopalthis madates, sp.n. (Tab. XXXIX. figg. 16, 164, 6; 11, 17a, ¢ .) 
Male. Primaries pale reddish-brown, crossed from the costal to the inner margin by three very fine waved 
white lines, the outer margin thickly irrorated with white scales, the marginal line with small black 
points, a large white dot at the end of the cell, and a curved white line crossing the wing close to the 
apex from the costal to the outer margin, the fringe white; secondaries paler in colour than the 
primaries, and crossed below the middle by two narrow zigzag white lines, the apex and outer margin 
thickly irrorated with white scales, the fringe brownish-white ; the underside darker brown, with the 
white markings very similar to those above: head, thorax, and abdomen pale brown, the segments of the 
abdomen banded with white, the antenne pale brown; the palpi brown, the tuft of hairs slightly 
yellowish ; the fore legs brown, the hind legs whitish. The female similar to the male, but generally 
larger, and with the palpi very differently formed and dark brown in colour. Expanse, ¢ 1, 2? 13% 
inch. 
Hab. Merxtco, Coatepec (coll. Schaus); Panama, Volcan de Chiriqui 2000 to 3000 
feet (Champion). 
Mr. Champion captured a large series of this very distinct species “at light” in 
Chiriqui. A single specimen from Mexico in Mr. Schaus’s collection differs from all 
the others in having the veins white between the white lines on the primaries.
