Head smooth, the vestiture curving down over the face ; eyes moderate 

 or smallish; ocelli variable. Antennas as in the Gelechiidee; scape long 

 and slender, often with a pecten, which is sometimes reduced to a single 

 bristle at its base ; never with eye-cap. Antennas sometimes as long as 

 the fore wing, never much longer or very short. Palpi divergent, with

 blunt apex; with broad dorsal and costal fringe. Anal angle never 

 well marked; the apex occasionally caudate (fig. 183), as in the Lyone-
