 "Antennpe 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 brow.i streak marsMied above with golden, ex- 

 tending nearly to the first costal «>.reak. Thf^n ire four silvery costal streaks, 

 all dark margined, the first vt^.y oblique, the second convex toward the base of 

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

 toward the base. Two silvert dar\ margined dorsal streaks, the first opii'>'ite 

 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. uicidicodella, 

 which it most closely resembles, by having a ies"- jKMtion of the wing 

 golden ; and by difterences in the basal strei^k. which in L. argenti- 

 fimhriella is longer, narrower and dar': 'irown, margined above by 

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

 entirely golden. Expanse 6.5-7 mm. 



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

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