Kinsey: Gall Wasp Genus Cynips 
363 
Labelled Winfield, Kansas; galls June 8 and 28, August 22, and Septem- 
ber 7, 1927; adults January 4 and 6, 1928; Q. Milhlenbergii, R. Voris 
collector. 
This insect is poorly distinct from the agamic form of 
variety gemmula. Since gemmula appears to be of hybrid 
origin with fuscata as one of the parents, every intergrade 
between these two insects is to be expected on the northern 
edge of the range of fuscata, and fuscata will appear as a 
segregate from the hybrid over most of the range of gemmula. 
To judge from our rather limited material, fuscata is a fairly 
constant insect over the good sized geographic area from 
southern Indiana to southeastern Kansas.

Dr. Voris found galls of this variety as early as June 8 in 
southeastern Kansas. By June 28 the balls were full size, but 
it was not until late in August that the insects were large 
enough to be bred in our window boxes. Our emergence dates 
for fuscata are December 1, 6, 8, 10, 16, and 18, and January 
1, 4, and 6. In general the later emergence was for the more 
southwestern localities. 
The alternate, bisexual generation of this variety should 
nearly agree, in both insect and gall characters, with the bi- 
sexual form described for variety gemmula.
