"Gall. A bud gall on Quercus agri folia, globular, the diameter 

 22 mm. or more, whitish, smooth and glabrous, apically with a very

"This species is allied to the genus Ampliibolips, from which it is 

 excluded by the tarsal claws being simple. " (J. J. Kieffer). 



I have examined an example of both gall and gallfly of C. 

 maculipennis. kindly furnished by Mr. Baker.
