482 HETEROCERA. 
1. Ariphrades setula, sp.n. (Tab. XL. figg. 9,9 a, 3.) 
Male. Primaries and secondaries uniform pale brown ; the primaries crossed about the middle from the costal 
to the inner margin by a narrow dark brown band, a black spot at the end of the cell, a large elongated 
tuft of pale brown scales just beyond it, and a submarginal indistinct waved greyish-brown line extending 
from the costal margin close to the apex to the inner margin, the marginal line dark brown ; the fringe 
of both wings brown; the underside paler brown, that of the secondaries crossed below the middle by 
two faint brown lines: head, thorax, and abdomen brown; the antenne paler brown, with the tuft 
blackish-brown ; the palpi brown, with some greyish scales on the second joint; the legs brown. Ex- 
panse 14 inch. 
Hab. Panama, Caldera in Chiriqui (Champion). 
This species is not very closely allied to any other Deltoid known to me; the tuft of 
long scales at the end of the cell on the primaries in the male at once distinguishes it. 
One specimen only, a male, was captured by Mr. Champion. 
IPNEA. 
Ipnea, Walker, Cat. xvi. p. 190 (1858). 
Walker founded this genus upon a female insect from Pard. Of one of the species 
" now added we have specimens of both sexes. 
1. Ipnea marina, sp. n. (Tab. XL. fig. 10, .) 
Male. Primaries pale yellowish-brown, crossed from the costal to the inner margin by numerous waved darker 
brown lines, two only of which (one near the base, the other beyond the end of the cell) are well defined, 
a row of three black spots extending from the anal angle towards the apex, and beyond them in a line 
are two very minute black dots on the costal margin close to the apex, the marginal line with black 
points, the fringe dark brown; secondaries dull brown, with an indistinct spot in the cell, and a narrow 
line crossing the middle of the wing from the costal to the inner margin, the fringe greyish-brown ; the 
underside paler than above, that of the primaries clouded with darker brown: head, thorax, palpi, and 
antenne;pale yellowish-brown; the abdomen dark brown, with the anal tuft yellowish-brown ; the legs 
pale brown. The female very similar to the male, but generally paler in colour. Expanse, ¢ 2, 
13 inch. 
Hab. GuaTEMALA, Quiche Mountains 7000 to 9000 feet, Panajachel 5000 feet, Volcan 
de Atitlan 2500 to 3500 feet (Champion).—Ecuapor, Loja. 
This species varies considerably in colour, some examples being much darker than 
others. A specimen from Ecuador in M. Dognin’s collection resembles the darker 
individuals from Guatemala. 
2. Ipnea ardalus, sp.n. (Tab. XL. fig. 11, 2.) 
Female. Primaries and secondaries uniform dark brown, the primaries with an elongate broad orange-coloured 
band on the inner margin which does not reach the base or the anal angle, the fringe of both wings dark 
brown; the underside uniform pale brown, without any markings: head, thorax, abdomen, palpi, 
antenne, and legs brown. Expanse 1% inch. 
Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). ° 
One specimen.
