"Antennae silvery, annulated with darkish brown. Head, front and thorax 

 silvery-white. Anterior wings silvery, pale golden from nearly the middle to 

 the tip, with a long basal dark brown streak margined above with golden, ex- 

 tending nearly to the first costal streak. There are four silvery costal streaks, 

 all dark margined, the first very oblique, the second convex toward the base of 

 the wing. The first costal dark margin is decided and extended on the costa 

 toward the base. Two silvery dark margined dorsal streaks, the first opposite 

 the second costal streak. The apical spot black, hinder marginal line dark 

 brown, cilia silver-gray. Hindwings silver-gray, cilia the same." 



The above is Clemens' description. 



The larva makes a tentiform mine on the underside of leaves of 

 oaks. The pupa is suspended in the mine in a thin web. 



The imago may easily be distinguished from L. lucidicostella, 

 which it most closely resembles, by having a less portion of the wing 

 golden ; and by differences in the basal streak, which in L. argenti- 

 jimbriella is longer, narrower and dark brown, margined above by 

 a narrow golden line. In L. lucidicostella the basal streak is 

 entirely golden. Expanse 6.57 mrn. 



The type of longistriata F. & B. at the Museum of Comparative 

 Zoology, Cambridge, Mass., is identical with argentijimbriella Clem.
