species is distinct from the European hypericella, and hyperella is not 

 invalidated by Hiibner's name. I, therefore, reinstate Ely's species 

 and sink Meyrick's name. 



The stout, gently recurved clasper of hyperella distinguishes it from 

 both lythrella and arcueUa. The clasper of lythrella is slender and 

 straight, and that of arcueUa is stout and straight. The separation 

 of lytJvrella from gelidella is discussed under lythrella. The females, 

 however, give the best characters for separating hyperella from 

 arcueUa. The signum is present in arcueUa, absent in hyperella.

 cent preceded by carmine and followed by whitish scales ; discal spot 

 at end of cell white ; from middle of costa to center of wing a strong

 wardly curved to between veins 6 and 7, then turned back, parallel
