Cynips Q. pomiformis, n. sp. 



Globular, polythalamous galls, sessile on the twigs of Qiieixiis Agri- 

 folia^ much resembling small round apples except that the apex is not 

 depressed as is usually the case in this fruit. Size from one to two inches 

 in diameter. Color various shades of brown, depending upon the degree 

 of exposure to the sun. The smoothish surface sometimes with a it'ff 

 small, hard, scattered wart-like points. In the larger specimens there are 

 faint lines reaching from the base to the apex, as though it were divided 

 internally by septa ; but no such divisions are found. The interior is 

 a rathef dense mass of yellowish brown cellular tissue, in which, near the 

 base, lie closely imbedded the thin walled larval cells. 



I received these galls last summer from my brother, H. D. Bassett, of 

 San Francisco, Cal. The exact locality where found was not mentioned. 

 The flies began to appear the first of March. They are all females, and 

 judging from the appearance of the galls they seem to belong to the 

 dimorphic class whose cycle of change is completed in one year.
