Kinsey: The Genus Neuroterus 
105 
TYPES. — Females, males, and galls. Holotype female, paratype 
females, males, and galls at the Philadelphia Academy ; paratype females, 
males, and galls at The American Museum of Natural History and the 
Museum of Comparative Zoology, and in the Beutenmuller (?) and 
the Kinsey collections. From Waterbury, Connecticut; Q, alba; Bassett 
collector. 
Bassett described this gall as appearing as soon as the 
oak leaves begin to expand, in April or May, and maturing 
within a few weeks, by the time the leaves are fully expanded. 
The above descriptions are made from a good-sized series of 
types.
