seven others are doubtfully referred to it. The female of A. /ydia has the antenne 
quite simple and the palpi rather small. 
1. Aristaria lydia, sp.n. (Tab. XX XVII. figg. 20, 20a, 3.) 
Male, Primaries dark brown, with a small black spot at the end of the cell, which has a few minute greyish 
scales on the outer side, a greyish-white submarginal line crossing the wing from the costal to the inner 
margin, and the space between it and the outer margin thickly irrorated with greyish-white scales (these 
in some specimens being almost obsolete); secondaries uniformly brown, slightly paler than the primaries, 
and with a short greyish-white line close to the anal angle; the marginal line of both wings black, the 
fringe brown; the underside pale dull brown, the greyish-white lines showing very faintly as above: head, 
thorax, abdomen, and legs dark brown; the antenne and palpi reddish-brown, the hairs on the antennz 
and at the end of the palpi yellowish-brown. The female similar to the male in colour and markings. 
Expanse, ¢ ?, 14 inch. 
Hab. Guatemata, Volcan de Atitlan 2500 to 3500 feet (Champion); Costa Rica, 
Volcan de Irazu 6000 to 7000 feet, Rio Sucio, Caché (Rogers); Panama, Chiriqui 
(ftbbe), Volcan de Chiriqui 3000 to 4000 feet (Champion). 
A few specimens only have been received. Our figure is taken from a Chiriqui 
example. 
2. Aristaria (?) lysis, sp.n. (Tab. XXXVII. fig. 21, 2.) 
Female. Primaries and secondaries dull brown; the primaries crossed from the costal to the inner margin by 
two narrow waved darker brown lines—the first near the base, the second beyond the cell,—and with a 
variable rather large oval pale yellowish-brown spot (larger and brighter in colour in some examples) at 
the end of the cell; both wings with a submarginal row of minute yellowish-white dots, these being more 
distinct in some specimens than in others: head, thorax, palpi, antenne, abdomen, and legs dull brown. 
Expanse 1,3, inch. 
Hab. Mexico, Coatepec (coll. Schaus); GuatemaLa, Volcan de Atitlan 2500 to 3500 
feet (Champion); Costa Rica, Rio Sucio (Rogers). 
Varies considerably in colour and in the distinctness of the markings. The specimen 
from Mexico is duller in colour than any of the others before us. Our figure is taken 
from a Guatemalan example. 
3. Aristaria (?) pentheusalis. 
Bleptina pentheusalis, Walk. Cat. xvi. p. 128 (9)'. 
Male, Very similar in colour to the female, but with a reddish-brown spot at the end of the cell; the antenne 
tufted about the middle (unfortunately the palpi are broken off). 
Hab. Costa Rica, Volcan de Irazu 6000 to 7000 feet (Rogers) ; Panama, Volcan de 
Chiriqui 2000 to 3000 feet (Champion).—Venezvueta!. 
Our female specimen agrees with Walker’s type in the National Museum. 
4. Aristaria (?) ? | 
Hab. Panama, Volcan de Chiriqui 4000 feet (Champion). 
One specimen, apparently a female, in very poor condition, without abdomen.
