bright green, tinged with yellowish. The larvae desert their mines to form 

 new ones, hence they are never extensive, sometimes blotches, and again ir- 

 regular galleries along the midrib, with lateral branches. The "frass" is 

 voided at the entrance opening beneath. I was not successful in breeding the 

 larvae on Desmodium.

B. pomif olie 11a. Head and face very pale ochreous, with the tuft 

 tipped with brownish. Antennae pale ochreous, dotted above with dark fus- 

 cous. Fore wings whitish, tinged, with pale yellowish, freely dusted with 

 brown. On the middle of inner margin is a large dark brown, oval patch, 

 forming, with its opposite when the wings are closed, a conspicuous, nearly 

 round dorsal patch ; a streak of the same hue, from the costa opposite it, run- 

 ning to the inner angle of the wing and tapering from the costa where it is 

 broadest. At the tip is a round, dark brown apical spot, and in the cilia a 

 dark brown hinder marginal line. Hind wings pale brownish ochreous, cilia 

 the same. 



The larva feeds externally on the leaf of apple, at least at the time it was 

 taken, in the latter part of September. It is cylindrical and submoniiiform ; 

 tapers anteriorly and posteriorly ; with punctiform points and isolated hairs, 

 first segment with rather abundant dorsal hairs ; thoracic feet three, abdomi- 

 nal four and very short, terminal one pair. Head small, ellipsoidal, brown ; 

 body dark yellowish green, tinged with reddish anteriorly ; hairs blackish and 

 short. 



Early in October the larva enters the pupa state, weaving an elongated, 

 dirty white, ribbed cocoon, and appears as in 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 inner margin, on the fold, is a small dark fuscous mark, consisting 

 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 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 nervnles, 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 De- 

 pressaria. The discal nervure is oblique. The interior basal angle rounded, 

 and the margin slightly excised behind it. 



Head and forehead between the antennae, 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 ivith scales; the third smooth, aciculate, and about one-third 

 less long than the second. Maxillary palpi very short. Antennae about one- 

 half as long as the fore wing, simple and filiform ; basal joint short. Tongue 

 scaled, about as long as the anterior coxae.
