oval. The subcostal is simple. The discoidal does not join 

 it, gives rise to three veins to the hind margin, and is deflected 

 towards the base. The median is two-branched, the upper 

 one being bifid about its middle. 



Head smooth. Forehead and face rounded. Ocelli large. 

 Eyes oval and rather prominent. Labial palpi moderately 

 long, rather slender, pointed and somewhat squamose; the 

 terminal joint shorter than the second. Antennae slender, 

 simple in the ? , rather densely ciliated in the $ . Tongue 

 slightly scaled and very short. 



The insect belonging to this genus, which is nearly allied 

 to Glypliipteryx of Hiibner,* has the curious habit of strutting 

 about broad leaves in shaded places, with its fore-wings 

 somewhat spread and the hind-wings turned forward at right 

 angles to the costa of the fore-wings, so as to display the 

 surface of the under pair. It is easily recognized by this 

 characteristic alone. 



B. pavonaceUa.'f Head and thorax fuscous; face whitish 

 beneath. Labial palpi white, with three fuscous rings, one 

 at the end of the second joint, one at the base of the terminal 

 and one near its tip. Antennas fuscous, annulated with 

 white. Fore-wings fuscous, mottled with whitish, especially 

 on the middle of the wing, with a fuscous spot on the middle 

 of the disk, ringed with whitish. Near the hinder margin is 

 a black band, not extended to the costa nor the inner margin, 

 with two sharp indentations of the general hue internally, 

 and containing on its middle a streak of brilliant scarlet-blue 

 metallic scales. Along the costa are one or two faint spots 

 of the same hue. Hind-wings fuscous, whitish at the base 

 and along the costa, with a short white line near the hind 

 margin, above the inner angle of the wing, and a rather faint 

 scarlet-blue metallic hued band on the hind margin, from near
