CALLIRHYTIS GEMMIFORMIS (Beutenmuellcr) 



Andricus (jcmmiformu Beutenmuellee, Caiiad. Ent.. vol. 4fl, 1017, pp. 34(>-7. 



Galls of this species have been collected on Q. alba at Fort Sheri- 

 dan, Kavinia, and Glen Ellyn, 111., and on Q. hicolor at Fort Sheri- 

 dan and Wilmette. Galls collected October 29, 1916, contained 

 pupae on September 17, 1917, and adults on November 15. These 

 would probably have emerged in the spring of 1918. From galls 

 collected in October, 1918, living flies were cut December 2. 1919, 

 which agree with the type. As the claws are simple the species is 

 here transferred to (JalUrhytis. 



CALLIRHYTIS HUMICOLA (Kinsey) 



Andricus liiniiicola Kinsey, Bull. Amer. Mils. Nat. Hist., vol 46, 1922. p. 2S3. 

 pi. 24, fig. 13. 



The gall of this species was described by the writer in 1921 as 

 Weld 1501. '^ The next year the species was described from a single 

 female from a gall on Q. keUoggii at Ashland, Oreg. The writer 

 collected galls on this host at Siskiyou, Oreg.; and in California at 

 Scott Bar and at Baird (where fresh galls seemed nearly full 

 grown in late May), at Fort Jones, at Placerville, and at Milford, in 

 Lassen County, on August 2 some cells were full of translucent 

 nutritive matter while others contained full-grown larvae. Tlie 

 galls are common also on Q. loislketul, being seen at Baird, Bartlett 

 Springs, Lakeport, Ukiah, Santa Kosa, on Mount Diablo, at Los 

 Gatos, in Palo Colorado Canyon in the Santa Lucia Mountains, in 

 the Santa Ana Mountains, and in Waterman Canyon in the San 

 Bernadino Mountains. In California Redwood Park galls were 

 found at the base of sprouts which had come up about the base 

 of stumps on the fire trail around the rim of tlie Big P)asin and 

 adults were already emerging on April 20; others came out April 

 25, 27, 28, 1922. Ten measured individuals range from ;3.G— t.l mm. 

 Average, 3.83 mm. 



CALLIRHYTIS INFUSCATA (Ashmead) 

 Andricus mfnscatus x\shmead, Trans. Aiiicr. Ent. Sot-., vol. 14. ISST, pp. 128, 144. 

 This species was described from Jacksonville, Fla., from galls on 

 Quercus cateshaei, the adults emerging in Marrli. As the tai-sal 

 claws are simple the species is here transferred to CaUlrhytU. The 

 writer has collected the galls on the above liost at Green Cove 

 Springs, Marianna, River Junction, Madison, Tallahassee, Carabelle, 

 Gainesville, Ocala, St. Petersburg, and Clearwater, Fla. Simihir 

 galls were seen at Marianna on Q. mmilandica and Q. chierea and on 



5 Proc. U. S. Xat. Mus., vol. 59, p. 243.
