Mr. Ehrhorn, who had recently returned from a vacation 

 trip to C^alifornia, remarked on conditions in the valley re- 

 p-ions, it being the dry time of the year was very unfavorable 

 for insect collecting. He also gave some account of his visit 

 to the State insectary at Sacramento, and to the Panama- 

 Pacific Exposition at San Francisco. At the latter place he 

 had noted an interesting coUection of insects in the School 

 Exhibit from Bolivia, and in the exhibit of the Field Museum 

 there were valuable life history exhibits. 



Epyris sp. — Mr. Swezey exhibited a specimen of a large 

 Bethylid which he had caught on a cane leaf at the Experi- 

 ment Station, October 2Tth. It is apparently this genus, and 

 is a foreign insect not previously observed here. It is much 

 larger than any of the native Bethylids. 



Andricus quercus-californicus (Bass.). — Mr. Swezey ex- 

 hibited a large gall collected from the Oregon oak at Eugene, 

 Oregon, in July, 1915, and specimens of tlie Cynipid causing 

 it. The specimens were obtained by cutting open the gall, in 

 which were seven cells or chambers near the center, five of 

 which contained each a single Cynipid, while the other two 

 contained parasites, Tetrastichus standfordiensis Ful., 16 and 

 17 respectively in each cell. 



8ynergus sp. — Specimens of what appeared to be a new 

 species of this genus of Cynipidae were exhibited by Mr. Swe- 

 zey. They were reared from small spherical galls on the 

 sterile catkins of Castinopsis clirysophylla, collected on the 

 s'lmmit of Mt. Tamalpais, California, August 7th, 1915.
