480 HETEROCERA. 
MARGITES, gen. nov. 
Male. Head small, the thorax broad, the tegule long; the abdomen moderately stout, extending slightly 
beyond the wings. Palpi porrect, very thickly clothed with large scales; the first joint small; the 
second joint extending beyond the eyes; the third joint very broad, turned back over the head and tufted 
with rather long hairs. Antenne about half the length of the primaries, fine, and very slightly pectinated. 
Fore legs long, densely covered with hairs ; the middle and hind legs slender. The primaries long and 
narrow ; the costal margin straight almost to the apex, where it is slightly rounded; the outer margin 
very angular in the middle; the inner margin straight. The secondaries rather long, angular on the 
outer margin, much rounded at the anal angle. The fringe of both wings rather long. 
Type Margites bugaba. 
Allied to Bocana, but separable therefrom in the male sex by the very different form 
of the palpi and by the angular outer margin of the primaries. 
1. Margites bugaba, sp.n. (Tab. XL. figg. 5, 5a, 2.) 
Male. Primaries brown with a purplish shade, with three faint darker brown lines crossing from the costal to 
the inner margin, a large greyish spot at the end of the cell, and a number of greyish-white spots at the 
apex and along the outer margin, the fringe brown ; secondaries dull brown, lighter along the costal margin, 
the outer margin with white points; the underside pale greyish-brown, both wings crossed beyond the 
middle by a narrow darker brown line: head, thorax, and palpi dark purplish-brown, the tuft of hair on 
the latter very pale yellowish-brown, the abdomen dull brown, the legs brown. Expanse 1,4, inch. 
Hab. Panama, Bugaba 800 to 1500 feet (Champion). 
Very distinct from any other Deltoid known to me. The two specimens received 
appear to be both males; one, unfortunately, is in a very damaged condition, having 
lost the palpi and abdomen. 
ARGANTA, gen. nov. 
Male. Head small, the thorax somewhat broad, the tegule short; the abdomen stout, not extending beyond 
the wings. Palpi slender; the first joint short; the second joint long, reaching the top of the head; the 
third joint about the length of the second, slightly tufted with fine hairs. Antenne simple, about half 
the length of the primaries. Legs rather short and stout. The primaries moderately long; the costal 
margin sharply arched close to the base, then nearly straight to the apex, thickly tufted with long 
scales from the base to near the middle ; the outer margin rounded to the anal angle; the inner margin 
quite straight. The secondaries rather long and broad, considerably rounded from the apex to the anal 
angle; the inner margin straight. 
The female differs from the male in having the costal margin of the primaries quite straight and without tuft 
of scales, and the palpi small, 
Type Argania pilosa. ; 
This curious genus is quite unlike any other Deltoid known to me. In the shape of 
the primaries of the male it very closely resembles Symmachia in the Lemoniine. 
1. Argania pilosa, sp.n. (Tab. XL. figg. 6, 6a, 3; 7, 2.) 
Male. Primaries yellowish-brown, with a large tuft of long scales on the costal margin, a grey streak on 
the outer margin below the apex, and several indistinct grey spots near the anal angle, the marginal line 
and the fringe greyish ; secondaries rather darker in colour than the primaries, very thickly clothed with 
brown scales about the middle: head, thorax, abdomen, and legs brown, the palpi and antenne pale 
yellowish-brown. The female altogether darker in colour; the primaries with two very faint brown 
lines crossing from the costal to the inner margin, and the grey lines and spots on the outer margin more 
distinct. Expanse, ¢ 92, 1,3, inch.
