willow. The pupa is known by a thin, almost circular, projec- 

 tion standing out from its back. The young larvae winter in 

 cases "composed of the leaf of the willow, on which the larva

 form a cylindrical tube closed at one end and lined with silk." 

 (Trouvelot.) L. Ejyhestion Stoll is blue black, with three black 

 lines on the hind edges, and just within the outer border is a 

 row of orange colored spots. It lives on the scrub-oak (Quercus
