ARGANTIA.—ARIPHRADES. 48] 
Hab. Guatemaua, Cerro Zunil 4000 feet, Volcan de Atitlan 2500 to 3500 feet 
(Champion). 
The female of this species is very similar to the corresponding sex of Bocana (*) 
anteros, from Chiriqui; but the males are very distinct. We figure both sexes. 
HYPOECHANA, gen. nov. 
Male. Head and thorax small; the abdomen slender, not extending beyond the wings. Palpi covered with 
hairs; the first joint small; the second joint three times the length of the first ; the third joint small and 
pointed. Antenne rather more than half the length of the primaries, very slightly pectinated, and tufted 
in the middle. Legs slender. ‘The primaries with the costal margin slightly curved near the base, then 
straight to the apex; the outer margin rounded from the apex to the anal angle; the inner margin 
straight ; on the costal margin about the middle is a large tuft of long scales, this being curved backwards 
over the wing and almost covering the end of the cell. The secondaries large; the outer margin rounded 
from the apex to the anal angle; the inner margin straight, and clothed with rather long hairs. 
Type Hypoechana fuliginosa. 
1. Hypoechana fuliginosa, sp. n. (Tab. XL. fig. 8, ¢ .) 
Male. Primaries brown, crossed before the middle from the costal to the inner margin by a wide darker brown 
band, this being edged on each side with a narrow black line, and beyond the band from the middle to the 
inner margin much paler in colour, the tuft of long scales on the costal margin dark blackish-brown, the 
outer margin with black points; secondaries dull blackish-brown, paler along the costal margin, a faint 
dark brown line crossing the wing about the middle from the costal to the inner margin, and a faint sub- 
marginal yellowish-brown line extending from the apex almost to the anal angle, where it is much more 
distinct, the outer margin with black points; the fringe of both wings dark brown; the underside 
greyish-brown, almost without markings: head, thorax, abdomen, antenne, palpi, and legs dark brown. 
Expanse 1} inch. 
Hab. Mexico, Coatepec (coll. Schaus), Atoyac in Vera Cruz, Teapa in Tabasco (/. 
H. Smith); Guatemata, Volcan de Atitlan 2500 to 3500 feet (Champion); Panama, 
Chiriqui (Ribbe, in mus. Staudinger). 
Varies considerably in colour, Panama specimens being paler than those from 
Mexico. 
ARIPHRADES, gen. nov. 
Male. Head small, the eyes very prominent; the thorax narrow; the abdomen slender, extending slightly 
beyond the wings. Palpi large, porrect, thickly clothed with long hairs ; the first joint small; the 
second joint long and broad; the third joint very small. Antenne rather thick, slightly pectinated, and 
tufted beyond the middle (the apical portion wanting). Legs short and stout, the fore pair covered with 
hair. The primaries long, rather broad from the apex to the anal angle; the costal margin almost 
straight, but a little rounded at the apex ; the outer margin slightly rounded ; the inner margin straight ; 
between the end of the cell and the outer margin is a tuft of long scales that almost reaches the outer 
margin. The secondaries rather long and narrow; the costal margin straight; the outer margin very 
angular; the inner margin and the abdominal fold thickly covered with fine hair. 
Type Ariphrades setula.
