1. D. ligulella Hiibner. Fore wing about four and a half times as long as wide;

 reduced and not meeting each other. Fore wing normally fuscous brown, with discal

This is var. pometella Harris. In the typical form the costa is broadly cream- 

 white, contrasting with the ground color. (The names Chcetochilus contu'bernatellus 

 Fitch, pauciguttellus and flavivittellus Clemens, and reedella, ruderella, and quer- 

 cipomonella Chambers, mostly represent variant forms.) 



Common and generally distributed; often in injurious numbers on apple (the 

 Palmer-worm) but sometimes rare for years together. Caterpillar green, less often 

 brown, head yellow-brown, black-brown in dark specimens; cervical shield concol- 

 orous with head, often heavily marked with black in dark specimens. Tubercles 

 black; body with a narrow dorsal and very broad subdorsal diffuse dark bands, 

 separated by whitish stripes. A leaf-roller on apple and oak.

 brown transverse bands, the second formed by the rounded orbicular and claviform 

 spots, the third including the discal bar. Hind wing fuscous, very slightly trans- 

 lucent between the veins. Wing about three and a half times as long as wide. 

 Second segment of palpus black on outer side, finely edged with white; third pale
