Norton as reared from twigs of Betula nigra collected in Con- 

 necticut, and describes the female. His description does not 

 agree well with the species here considered as attenuatus, but 

 does agree with a female which is a different and undescribed 

 species and bears a Bradley manuscript name. The author is 

 inclined to believe that Patton did not have attcnuata as here 

 determined, because the female of attenuata does not have 

 pale marks on the abdomen.

 necticut, which agrees with the description and is without 

 doubt Ashmead's species, has been made a neotype.
