Remarks. — ^Although very close to grotella and hetulella, this species 

 is distinct from both in genitalia and coloration. From grotella it 

 may be distinguished by the narrower clasper and from hetuleUa by 

 the rectangular transtilla in the males; in the female it may be dis- 

 tinguished from grotella by the small number of hairs on the posterior 

 part of the genital plate and from hetuleUa by the slitlike ostium.
