(J. D. Mitchell). He has collected galls on Quercus geminata at Car- 

 rabelle, Clearwater, and Daytona Beach, Florida. 



Biology.— Growing galls are found in October secreting honey-dew 

 and frequented by flies, wasps, and yellow jackets. Galls from Texas 

 sent to Evanston, Illinois, gave flies December 14. Others remained 

 inside the galls and were cut out alive on December 20 and February 

 6. Under natural conditions emergence is probably in late fall. 

 When attacked by quest-flies, which make cells in distal parts of 

 the gall, the size of the gall is much reduced.

Agamic female. — Uniformly reddish. Head quadrangular, width 

 2.8 times length of eye. Interocular space 0.72 transfacial and area 

 twice as broad as high. Facial line 0.82 times transfacial. Malar 

 space 0.63 eye, groove shallow. Palpi 5 and 3. Antennae 13; 

 lengths as 19:7:19:13:11:10:10:10:9:9:9:9:18. On same scale width 

 from 7 to end is 8. Mesoscutum smooth and polished, grooves per- 

 current. Scutellum faintly margined, disk granulate. Wing longer 

 than abdomen but reduced, veins about radial cell clouded, no areo- 

 let, pubescent and ciliate. Legs short and stout, evidently adapted 

 for digging, furcula of fore tibia reaching beyond middle of metatar- 

 sus, spur on middle tibia as long as normal spines, claws simple. 

 Hypopygium short, ventral spine broad, short. Ovipositor longer 

 than antenna, stout. Using width of the head as a base the length 

 of mesonotum ratio is 1.1, antenna, 1.8-2.0, ovipositor 1.9-2.2, wing 

 2.6-2.9. Range in length of 22 pinned specimens 2.3-3.1 mm. 

 Average 2.7 mm. 



Type— Cat. No. 24099, U.S.N.M. Type and 10 paratypes. 



Host. — Quercus geminata Small, and Quercus virginiana Miller. 



Gall. — Globular, hard, tan-colored galls occurring in numbers on 

 the under side of the leaf. Monothalamous, 4-6 mm. in diameter, 

 of dense cellular tissue. 



Habitat. — The type material is from galls collected at Clearwater, 

 Florida, November 7, 1919, on geminata and sent in as Hopkins U. S. 

 No. 15634 f . Flies issued December 8. Three paratypes from Jack- 

 sonville are probably from virginiana. The writer has seen galls at
