JUNE, 1860. 147 



Early in October the larva enters the pupa state, weaving 

 an elongated, dirty white, ribbed cocoon, and appears as an 

 imago during the latter part of the following April or early 

 in May. 



B. agnella. Head and face sordid white, the latter touched 

 with fuscous. Antennae dark fuscous. Fore-wings whitish, 

 washed with pale luteous-brown, which prevails especially 

 towards the tip and along the fold. About the middle of the 

 inner margin, on the fold, is a small dark-fuscous mark, con- 

 sisting of a few scales. The costa is dark fuscous from the 

 base, and about the middle of the wing gives off a short 

 oblique streak of the same hue, and another near the apical 

 third, which is fuscous near the costa and pale luteous-brown 

 beyond it, and margined exteriorly with white, especially on 

 the costa. The long scales in the cilia are tipped with dark 

 brown. Hind-wings brownish ; cilia brownish, with a rufous 

 tinge. 



Taken on the wing about the middle of May. 



MACHIMIA. 



Fore-wings with the hind margin obliquely pointed. The 

 subcostal nervure gives off a marginal branch near the basal 

 third, and at the end of the disk subdivides into four nervules, 

 of which the apical is furcate near the tip. The median is 

 four-branched, the medio-posterior remote from the penulti- 

 mate. The submedian is furcate at the base. In the disk is 

 a long, faintly indicated, secondary cell. The neuration of the 

 hind-wings like that of Depressaria. The discal nervure is 

 oblique. The interior basal angle rounded, and the margin 

 slightly excised behind it. 



Head and forehead between the antennas shaggy. Face 

 rather smooth, depressed and retreating. No ocelli. Eyes 

 small, oval and salient. Labial palpi rather long, remote 

 from the face, slender, curved and ascending ; second joint 

 roughened with scales ; the third smooth, aciculate, and about
