ANDRICUS CASTANOPSIDIS BeutenmucUer 



The writer collected galls on Mount Tamalpais, August 6, 1915. 

 Some had already dropped to the ground. The growing galls are 

 of a rosy-red color, fading to yellowish and tan as they mature. 

 These galls were kept in a breeding cage out-of-doors and living 

 flies were cut out of some August 13, 1917, while others still con- 

 tained larvae. The collection at Stanford has flies which emerged 

 July 7. Galls from Truckee were sent to the writer, collected by 

 L. E. Hildebrand, September 10, 1915. A dead fly was found in the 

 cage in August, 1918, and some of the galls still contained larvae. 

 The emergence may be delayed evidently until as late as the fourth 

 spring in some cases. Dr. E. C. Van Dyke sent galls from In- 

 verness, in Marin County, and the National Museum has galls 

 from Placer County. The writer saw the galls in California Red- 

 wood Park, on the Martis Peak trail at north end of Lake Tahoe, 

 on Mount St. Helena in Lake County, and they were very common 

 in the fall of 1922 on Taquitz Peak in the San Jacinto ^Mountains. 

 Old galls were seen on top of the mountain above Siskiyou, Oreg. 

 Prof. W. L. Jepson collected galls at Monterey and in Mendocino

ANDRICUS CHINQUAPIN (Fitch) 



Figites chinquapin Fitch, 5th Rept. Nox. Ins. N. Y., 1859, p. 820. 



Cynips fusiformis Osten Sacken, Proc. Ent. Soc. Phila., vol. 1, 1861, p. 61. 



Cynips capsula Bassett, Canad. Ent., vol. 13, 1881, p. 101. 



The two type galls of chinquapin in the National Museum from 

 Q. prinoides are similar to those of capsula from Q. hicolor (another 

 chestnut oak) and the two type flies of capsula sent by Bassett can 

 not be separated from Fitch's type fly which, however, lacks the 

 abdomen. 



The holotype of fusiformis in the Museum of Comparative Zo- 

 olog}^ has not been compared directly with the above types but 

 flies bred from the precisely similar gall on Q. alba can not be 

 separated from them and the writer concludes that these three 

 names all refer to one species making galls on different white oaks. 

 This view has also been expressed by William Beutenmueller in 

 letter. 



Tlie writer has taken the gall on Q. 7Jiontana, rock cliestnut oak, at 

 Ithaca, N. Y. ; Alexandria and Great Falls, Va. ; Washington, D. C, 

 where a fly ready to emerge was cut out of gall on IVIay 31. On Q. 

 alba at Evanston, New Lenox, (fly emerged June 7), and Fort
