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, " show- 

 ing 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: 



Female. — Dark yellowish-brown. Head coriaceous, broader than 

 thorax, axial line 0.6 of transfacial, facial less than transfacial, inter- 

 ocular area 1.48 times as broad as high, antennocular and ocellocular 

 spaces equal, malar space without groove and 0.68 length of eye, 

 antennae with last segment two and one-fifth times as long as thir-
