Aphilotiieix lucida. 



27. ApJiilothrix lucida, Hart. — The spherical, pale yellow 

 gall which is found on shrubby Quercus pedunculata, 

 Q. sessiliflora, and Q. pubescens, is generally about as large 

 as a cherry, but sometimes is found as big as a walnut. Its 

 whole surface is covered with stiff, stalky or fibrous pro- 

 jections, which stand out radialely, and terminate in a rusty 

 red papilla. In section it exhibits a hard texture, with 

 numerous egg-shaped cavities : in these live the larva3 of the 

 gall-fly, without being separately enclosed in an inner gall.
