Family 23. LAVERNID^I 



(Momphidaa; Cosmopterygidas ; Elachistidae, in part) 



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

 or smallish; ocelli variable. Antennas as in the Gelechiidas; 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 

 second segment smooth or tufted below, but never with a triangular 

 tuft; third segment variable in length, smooth, upturned, slender, and 

 regularly tapering; the palpus always upturned and much longer than 

 the head. 



Fore wing lanceolate, always narrow, the membrane rarely with a 

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

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

 tiidee, some Gracilariidas, and Polyhymno. R x from cell less than three-
