Eumayria floridana Ashmead
Eumayria mutiarticulata
Doctor Ashmead described a root gall on Quercus laurifolia Michaux in 1887 in Transactions American Entomological Society (vol. 14, p. 133) as Eumayria multiarticulata. Later in the same paper he described Eumayria floridana, male and female, without gall, from five specimens taken at large in March, 1SS7, in Florida. In the old Ashmead collection at the United States National Museum are three male flies with the label "Jacksonville, Florida," and bearing a white label with the word "type." These are evidently of the original five. The American Entomological Society probably has another one. In the Museum collection, however, probably years later, he placed a red label with "U.S.N.M. Type 2883" on a gall which answers the description of multiarticulata and also on a female fly and accessioned them as Eumayria floridana. Both bear the "U.S. D.A. No. 2647" and are from Georgiana, Florida. With these are 37 other females all bearing the same number. The emergence dates are April 12, 13, 19, 20, 25, 27, and May 3, 1882. Pinned in case with them is a slip with name " Eumayria multiarticulata, " showing that as that name had been applied only to gall, he wished to call the species floridana and wished the large series of reared flies to be included in the type series for in the type book he wrote "many types." Whether there were any males in the reared series or any females in the captured series is not known. The writer has reared both males and females from galls collected at Jacksonville, Florida, and these agree with both sexes in the Museum, so that there is no doubt that the Museum material belongs to one species.
As Ashmead 's description of the adults was very brief, the following notes are added from the type material in the Museum:
Gall. — Photographed from galls on Quercus catesbaei Michaux collected at Jacksonville, Florida. In the late fall the galls contain a thick translucent nutritive layer in each cell. They should be collected in the spring for rearing.
Host. — It was described from Quercus laurifolia Michaux. The writer has collected galls on nine other species of oak, as shown below.
Habitat. — From Quercus catesbaei at Ocala and Jacksonville, Florida, galls were taken and adults of both sexes reared that agree with the types in the United States National Museum. They were collected April 21 and April 25, 1914, and the flies emerged and died in the box before August 10. Galls of this species and on this host were seen at Green Cove Springs, Ocala, Madison, and Gainesville, Florida. Galls have been taken, but no flies reared from the following oaks:
Q. rubra Linnaeus at Ravinia, Fort Sheridan, Highland Park, and Evanston, Illinois.
Q. coccinea Wangenheim at Millers, Indiana, and Evanston, Illinois.
Q. velutina Lamarck at Hot Springs, Arkansas.
Q.falcata Michaux at Gainesville, Florida.
Q. texana Buckley at Boerne and Kerrville, Texas.
Q. marilandica Muenchhausen at Mineola, Texas, and Hot Springs, Arkansas.
Q. brevifolia Sargent at Marianna and Ocala, Florida.
Q. myrtifolia Willdenow at Carrabelle and Daytona, Florida.
