CALLIRHYTIS FLORIDANA (Ashmead) 



Andricus? ■floridanus Ashmead, Trans. Amer. Ent. Soc, vol. 14, 1887. pp. 

 132, 137. 

 This species was described from Q. chapmani from Florida. As 

 the types have the claws simple the species is transferred to Calli- 

 rhytis. The stem swellings of this species are found in the fall 

 covered with normal bark. They look hard and woody but when 

 cut into they are found to consist of a thick layer of soft white 

 parenchymatous tissue which cuts like cheese, the numerous cells 

 being deeply imbedded next to the true wood. The writer has col- 

 lected them on Q. stdlata and reared flies which agree with the 

 types. Galls from Poplar Bluff, Mo., contained pupae when exam- 

 ined in November, the adults emerging in the spring. Galls were 

 seen also at Texarkana, Ark., and Trinity, Tex. Galls collected at 

 Washington on April 3, 1921, had adults emerging and they con- 

 tinued to emerge until April 18. A moth, Nola phyJla Dyar, whose 

 larva feeds on the tissue of the gall, emerged April 16. \V. ]\Iiddle- 

 ton collected galls at East Falls Church, Va., on March 14, 1920, and 

 reared adults April 19 (Hopkins U. S. No. 14636*^). To test the 

 powers of flight of a Cynipid some recently emerged flies of this 

 species were carried in a vial to a dimly lighted corridor which had a 

 north window at the end and allowed to escape one by one at various 

 distances from the window, on a cloudy day. One was seen to make 

 a straight-away flight to the window at a distance of 45 feet. In 

 1924 the makers emerged April 26. 



CALLIRHYTIS FUTILIS (Osten Sacken) 



SEXUAL GENERATION 



The wart galls on the leaves of Quercus alba have been observed 

 at Williams Bay, Wis.; Evanston, Winnetka, Fort Sheridan, and 

 Moline, 111.; Cedar Rapids, Iowa; Poplar Blufi", Mo.; Tuskahoma, 

 Okla. ; Texarkana, Ark.; Elyria, Ohio; Farmingdale (Crosby), 

 N. Y.; Rosslyn and East Falls Church, Va. Brodie collected the 

 galls at Toronto and adults emerged July 17-29, 1893, and July 

 7-12, 1896. For rearing the galls should not be gathered until the 

 producer has reached the pupa stage, which in the North would be 

 about the first of July. The galls have been observed on Quercus 

 hicolor at Evanston, 111., and on the rock chestnut oak, Quercus 

 ■montana, at Ithaca, N. Y., and Alexandria and Bluemont, Va. The 

 galls were ver^' common on the leaves of white oak about Washing- 

 ton in the spring of 1924.
