Kinsey: The Genus Neuroterus 89 
This insect is very closely related to noxiosus form 
vernalis, but is constantly different in the lighter yellow bases 
of the antennae and the more pronounced spur on the first 
abscissa. The host, Q. Prinus, is very distinct from the host 
of noxiosus. The type material comes from 276 females and 
233 males bred by Dr. M. T. Thompson, the material not 
marked with a definite locality but very certainly from either 
the neighborhood of Providence, Rhode Island, or the eastern 
part of Massachusetts, where Dr. Thompson did practically 
all of his collecting.
