larva tapers posteriorly; it is submoniliform and slightly 

 flattened, with segments roundly mammillated on the sides. 

 The feet are three, the abdominal three and the terminal one 

 pair. 



The head is pale brown; ihe body bright green, tinged 

 with yellowish. The larvas desert their mines to form new 

 ones ; hence they are never extensive, sometimes blotches, and 

 again irregular galleries along the mid-rib, with lateral 

 branches. The " frass " is voided at the entrance opening 

 beneath. I was not successful in breeding the larvas on 

 Desmodiam.

/VtilJ'l B. pomifoliella. Head and face very pale ochreous, with 

 the tuft tipped with brownish. Antennas pale ochreous, 

 dotted above with dark fuscous. Fore-wings whitish, tinged 

 with pale yellowish, freely dusted with brown. On the 

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

 forming with its opposite, when the wings are closed, a con- 

 spicuous, nearly round dorsal patch ; a streak of the same 

 hue, from the costa opposite it, running 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 Hue. 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 submoniliform ; tapers anteriorly and pos- 

 teriorly ; with punctiform points and isolated hairs, first seg- 

 ment with rather abundant dorsal hairs ; thoracic feet three, 

 abdominal four and very short, terminal one pair. Head 

 small, ellipsoidal, brown ; body dark yellowish-green, tinged 

 with reddish anteriorly, hairs blackish and short.
