Evius hippia, Walk. Cat. iii. p. 640; Butler, Journ. Linn. Soc., Zool. xii. p. 431. 
Hab. Panama, Bugaba 800 to 1000 feet (Champion).—Gutiana, Surinam 1. 
Of this species Mr. Champion only obtained a single example, which agrees well with 
Stoll’s figure. 
2. Evius lineatus, sp. n. (Tab. IX. fig. 17.) 
Primaries creamy white, thickly lined with brownish black, the ground-colour near the base brownish ; 
secondaries uniform pale yellow: head, thorax, and the upperside of the abdomen dark yellow, the front: 
and base of thorax spotted with black; the underside of the abdomen and the anus white; legs white; 
antenne brownish white at the tips. Expanse 1 inch. 
Hab. Panama, San Lorenzo (Champion). 
A single example of this pretty little species was obtained. 
IDALUS. 
Idalus, Walker, Cat. iii. p. 645. / 
Walker founded this genus for the reception of Phalena admirabilis, Cram., a South- 
Brazilian insect. 
1. Idalus crinis, sp.n. (Tab. IX. fig. 18.) 
Primaries glossy white, a spot at the base and a narrow band crossing beyond the middle from the costal to 
the inner margin pale brown, bordered with a narrow black line on each side; between it and the base 
are two central yellow spots, three minute black streaks close to the anal angle, and one beyond on the 
outer margin near the apex; secondaries pure white, tinted with carmine on the inner margin: head and 
thorax white, spotted with red and yellow; abdomen bright carmine above; the anus, a central band of 
minute spots, and the underside white; antennz brownish black, pale at the tips. Expanse 17 inch. 
Hab. Mexico, Presidio (forrer). 
I have only received a single example of this insect ; it is allied to /. admirabilis, but 
very distinct. 
2. Idalus critheis, sp.n. (Tab. IX. fig. 19.) 
Primaries deep citron-yellow, crossed about the middle from the costal margin to near the anal angle by a 
narrow band of black spots, bordered on the inner side by a white band almost as wide, the base white, 
with a few black spots near the inner margin; secondaries yellowish white: head and central part of 
thorax deep yellow, front and base of thorax white; abdomen bright carmine on the upperside; the anus 
and underside white; antenne and fore legs brownish black; hind legs white. Expanse 12 inch. 
Hab. Panama, Volcan de Chiriqui (Ribbe, mus. Staudinger). 
This species resembles J. admirabilis, from which it is easily distinguished by the 
very much narrower black band crossing the primaries, and the entire absence of the 
red spots which are always present in that species.
