3. Megatomis anthippe, sp.n. (Tab. XX XVIII. figg. 25, 25a, 3.) 
Male. Primaries and secondaries dark brownish fawn-colour ; the primaries crossed from the costal to the 
inner margin by two narrow waved pale lines—the first close to the base, the second beyond the middle,— 
the discoidal mark pale yellow, a small black spot at the apex, and a submarginal row of very minute 
indistinct pale dots extending from the costal to the inner margin, the outer margin with minute black 
points ; the secondaries crossed about the middle by a pale yellowish-white line, with a submarginal row 
of dots as on the primaries, but slightly more distinct ; the fringe of both wings dark brown ; the under- 
side uniform pale yellowish-brown, crossed by very faint lines: head, thorax, abdomen, palpi, and 
antenne dark brownish-fawn-colour, the legs and the underside of the thorax and abdomen pale yellowish- 
brown. Expanse ;%, inch.

One specimen. 
4, Megatomis antonia, sp.n. (Tab. XXXVIII. figg. 26, 26a, 3.) 
Male. Primaries and secondaries brown, crossed below the middle by a darker brown line, on the inner side of 
which is a pale yellowish-brown line, this latter on the primaries not extending to the costal margin, the 
primaries with a dark brown dot at the apex, the fringe dark brown; the underside paler than above : 
head, thorax, abdomen, antenne, and legs brown, the palpi pale yellowish-brown. Expanse 13 inch.

Two specimens, both males. 
PERIPHRAGE, 
Periphrage, Herrich-Schiffer, Samml. aussereur. Schmett. p. 69 (1855). 
This genus is not mentioned by Walker in his Catalogue. It is closely allied to 
Megatomis, from which it may be distinguished by the much shorter and smaller palpi, 
shorter antenne, and rather narrower primaries. The single species included in the 
genus by Herrich-Schaffer came from Brazil, and we now have examples of it from our 
region ; two additional species are here added, both from Mexico. 
1. Periphrage barbatula. 
Periphrage barbatula, Herr.-Schaff. Samml. aussereur. Schmett. pp. 69, 82, fig. 396°. 
Hab. Guatemata, Pantaleon 1700 feet (Champion); Panama, Chiriqui (Ribbe, in 
mus. Staudinger ).—Braziu 1. 
We have received two specimens of this insect, and there is a third in Dr. Staud- 
inger’s collection. These examples are a little yellower in colour than Herrich-Schaffer’s 
figure, which represents a female ; those before us are all males, having a very small 
tuft of hairs almost at the end of the antenne. 
2. Periphrage mago, sp.n. (Tab. XX XVIII. figg. 27, 27a, 3.) 
Male. Primaries and secondaries pale brown, thickly irrorated with dark brown scales ; a white streak at the 
end of the cell on the primaries, below which is an ill-defined light-coloured band that extends to the 
inner margin and crosses the middle of the secondaries, a submarginal narrow white line extending from
