 BROTOLOMIA, Led. 

 NEPHBLODBS, Gn. 



B. iris, Gn. 



. N. minians, Gn. 

 Var. violans, Gn. 



Caldwell, rare — Crane. This species is also sometimes quite 

 injurious as a cut- worm. The imago flies during the day, and 

 I have taken it in September, on Solidago.

Caldwell, rare — Crane. 



*A. immanis, Gn. 



Purpuripennis is rare ; sera is more common ; nictitans is very 

 abundant and variable throughout the State. Immanis is local 

 and not common : in the hop-growing districts of New York 

 it is a serious pest, the larva boring into the crown roots of the 

 Hop and eating off the vine.

G. harrisii, Grt. 



Newark — Seib.
