486 HETEROCERA. 
1. Rhescipha obtusa. (Tab. XL. figg. 21, 21a, ¢.) 
Rhescipha obtusa, Walk. Cat. xxxiv. p. 1195 (@)’. 
Hab. Mexico, Jalapa (Hége), Coatepec (Brooks).—Braziu!. 
The two specimens from our region do not differ from the type in the National 
Museum. Our figure is taken from the Jalapa example. 
OROSCOPA, gen. nov. 
Female. Head small, the thorax broad; the abdomen stout, extending slightly beyond the wings. Palpi: the 
first joint quite small; the second joint long, rather flat; the third joint nearly as long as the second, 
very finely pointed, and with a small tuft of scales about the middle. Antenne simple, about half the 
length of the primaries. Legs long and slender, the spurs on the hind tibiee very long. The primaries 
long and narrow; the costal margin almost straight ; the outer margin angular and deeply dentated; the 
inner margin curved, forming a small lobe at the apex. The secondaries long and rather narrow; the 
costal margin slightly concave from the base to about the middle, then angular to the apex; the outer 
margin deeply dentated ; the inner margin much rounded at the anal angle, and clothed with long hairs. 
Type Oroscopa concha. 
This genus is not closely allied to any other Deltoid known to me. 
1. Oroscopa concha, sp.n. (Tab. XL. figg. 22, 22 a, 2 .) 
Female. Primaries pale greyish-fawn-colour, crossed from the costal to the inner margin beyond the middle by 
several very broken curved brown lines, the outer part of the wing being very thickly irrorated with 
brown scales, a whitish spot at the end of the cell, the marginal line with black and white points, the 
fringe pale brown; secondaries pale greyish-fawn-colour, thickly irrorated with brown scales, a waved 
line of small brown dots crossing the wing about the middie from the costal to the inner margin, and a 
rather dark brown dot at the end of the cell; the underside of both wings heavily marked with dark 
brown blotches: head, thorax, and abdomen pale greyish-fawn-colour, the antenne and palpi darker 
brown, the legs pale greyish-brown. Expanse 13 inch. 
Hab. Panama, Chiriqui (ibde, in mus. Staudinger). 
We have only seen one specimen of this curious species. In some respects it slightly 
resembles certain Geometride; but the form of the palpi at once shows that it does not 
belong to that family. 
2. Oroscopa punctata, sp.n. (Tab. XL. fig. 23.) 
Primaries and secondaries very pale greyish-brown, thickly irrorated with darker brown scales, a dark brown 
patch on the.outer margin of the primaries just below the apex, the secondaries with a brown spot at the 
end of the cell: head, thorax, and abdomen the same colour as the wings, the antenne, palpi, and legs 
pale whitish-brown. Expanse 1 inch. 
Hab. Panama, Chiriqui (Ribde, in mus. Staudinger). 
One worn example only. 
3. Oroscopa 2 
Had. Guatemata, Volcan de Atitlan 2500 to 3500 feet (Champion). 
One specimen, not in sufficiently good condition for identification or description.
