Jacksonville, Daytona, Tallahassee, and Gainesville on virginiana and 

 on geminata at St. Petersburg and Daytona Beach. Dr. J. C. Bradley 

 has collected galls at St. Simon's Island, Georgia. 



BELONOCNEMA KINSEYI, new species. 



Agamic female. — Reddish-brown, thorax darker. Head broader 

 than thorax, width 2.4 times length of eye, finely coriaceous, malar 

 space with groove and less than half length of e.ye, antennocular 

 space two-thirds occllocular, interocular area nearly 1.6 times as 

 broad as high, transfacial line 1.1-1.2 times facial, palpi 5- and 3- 

 segmented, antennae 13-segmented, third one and two-thirds times 

 fourth, 4-12 gradually shorter, last just over twice preceding. Pro- 

 notum with scattered punctures bearing white hairs. Mesonotum 

 shining, smooth, bare except for a few setigerous punctures along the 

 complete, deep, narrow parapsides, anterior and lateral lines very 

 faint. Scutellum rugose behind and on sides of disk, with scattered 

 setigerous punctures; base with two smooth distinct pits, sides with 

 triangular rugose impressions. Propodeum with two strongly 

 curved irregular ridges inclosing a rugose area. Front tibia pro- 

 longed on one side into a curved spine ending in a short blunt spine 

 and almost as long as the normal forked spine on the other side. 

 Hind tarsus shorter than tibia, second shorter than fifth, tarsal claws 

 simple. Wings hyaline, veins brown, second cross-vein heavily 

 clouded, second abscissa of radius strongly bent and thickened at 

 apex, areolet small and indistinct, cubitus reaching basal, surface 

 brown pubescent and margin ciliate. Abdomen smooth and shining, 

 compressed, longer than high, second segment with dorsal darker 

 area and patch of scattered hairs on sides, ventral spine about as 

 long as broad, ovipositor three-fourths length of antenna, eggs well 

 developed. Using the width of the head as a base, the length of 

 antenna ratio is 2.3-2.5; length of mesonotum ratio, 1.3; wing, 

 3.8-3.9; ovipositor, 1.8-2.0. 



Range in length of 62 pinned specimens, 2.0-3.1 mm. Average, 

 2.7 mm. 



Mr. A. C. Kinsey was the first to call the writer's attention to the 

 fact that adults bred from these leaf galls did not agree with the 

 description of Andricus virens Ashmead. Later an examination of 

 the type of virens showed it to be a Disholcaspis. 



Ti/pe..— Cut. No. 22832, U. S. N. M. Twenty-seven cotypes. 

 Fifteen, cotypes are in collection of William Beutenmueller. 



Host. — Quercus virginiana, Miller. 



Gall. — Similar to those of Belonocnema fossoria Weld. 



Habitat. — The type material is from Quercus virginiana collected 

 October 26, 1917, at Boerne, Texas. The galls then contained 

 pupae and adults. Flies emerged in cage before November 15, and
