able for breeding. W. Ebeling has sent me young galls from the Yosemite as early as June 21 (1928). The scant data indicate the emergence of the agamic adult from late November into December and possibly January. The life histories known for Cynips echinus, also of the subgenus Antron, suggest that we should look for the alternate, bisexual generation of guadaloupensis in a simple, fleshy-walled, capsule-like gall in the buds or on the young twigs of Q. chrysolepis. Such a gall is apparently undescribed. This bisexual insect should have the broadened and bluntly plow-shaped spine characteristic of the subgenus, and should be recognizable by this character, its host distribution, and its seasonal occurrence.
