Cynips Q. Californica, n. sp. 



Galls : Polythalamous, sessile on the branches of the Californian 

 White Oak (Quercus Elindsii ?) Sub-globular, but varying much in form 

 and size. A commcni form is what may be termed balloon-shaped, the 

 upper part perfectly globular, the lower tapering more or less to the sessile 

 base. They often occur of a long compressed oval form : these are 

 placed longitudinally on the branch and the length is two or three times 

 their breadth or thickness. Those of this form are often of monstrous 

 size, being ten or twelve inches in their greatest circumference. The 

 globular galls are from one to two inches in diameter. In color they are 

 of an opaque wiiite. They are usually smooth, but specimens occur that 

 have a more or less warty surface, and others are found that have slight 

 yellowish brown ridges. Internally ihcy arc of a uniform, dense cellular 

 structure, and the not very numerous larval cells (from one to a dozen) 

 lie closely imbedded in this cellular substance. 



From their shape and color these galls might easily be mistaken for a 

 species of white fungus which grows on trees.
