J have bred several moths from mines on Ostrya, agreeing 

 with Clemens' description of the mine, 

 made by the larva to v^hich he gave the 

 name virginiella. The larva spins a flat- 

 tened brownish yellow cocoon with a 

 ridge around the broader anterior end. 

 Mine oi N. virginiella. The imago may be characterized thus: 



Palpi whitish. Tuft reddish ocherous. Antennae fuscous, 

 eye-caps yellowish white. Thorax blackish, with golden and 

 purple reflections. 



The basal portion of the fore wing shows strong bronzy, 

 purple or blue reflections according to the incidence of the 

 light; in the apical portion the purple and blue reflections 

 alone are present. There is a brilliant, very pale golden fascia 

 just beyond the middle, narrowed toward the costa. Cilia 

 gray, tipped with silver, deeply so around the apex. Hind 

 wings and cilia gray. 



Fore and hind pair of legs shaded with dark gray, middle 

 pair of legs shining yellowish. Abdomen dark purplish above, 

 iridescent gray beneath. 



Expanse: 3.5 mm. 



These specimens come very close to N . apicialbella Cham., 

 and it is possible that a comparison with the type of A' . apicial- 

 bella would show them to be identical.
